Chemical Compound BPA Affects Lung Development says UC Davis Study

BPA Affects Lung Development
Collaborative efforts add critical information to understanding effects of BPA

BPA (bisphenol A), is used in the manufacturing of various plastics and food packaging, consumer products, some paper receipts, and medical devices. It is controversial because it exerts weak, but detectable, hormone-like properties which can mimic estrogen and may lead to far-ranging negative health effects including increased cardiovascular disease and diabetes in adults, increased cancer rates, including breast cancer, neurological difficulties, and hormonal and reproductive issues in both sexes and at all stages of life.

Recent results from research at the California National Primate Research Center (CNPRC) have shown that fetal BPA exposure during a critical window of susceptibility in the third trimester, at levels similar to those measured in human blood, caused an increase in mucin genes and mucous cell maturation in the lungs (Environmental Health Perspectives, National Institutes of Health).

This is of environmental health importance because increases in airway mucins are hallmarks of a number of childhood lung diseases that may be impacted by BPA exposure. Overly abundant secretion and storage of mucous can cause airway obstruction as found in a number of lung diseases including asthma and bronchitis.

CNPRC scientists Drs. Laura S. Van Winkle, Respiratory Diseases Unit, and Catherine A. VandeVoort, Reproductive Sciences and Regenerative Medicine Unit, along with co-authors Drs. Shannon R. Murphy and Miriam V. Boetticher (UC Davis Center for Health and the Environment), conducted this collaborative study to investigate the effects of BPA on fetal development.

Their data indicate that exposure to environmentally relevant levels of BPA during fetal lung development can alter expression of secretory genes (Muc5B, Clara cell secretory protein (CCSP)) and proteins (Muc5B mucins and CCSP) in the conducting airways. They also found that this increase is most pronounced in the bronchi (proximal conducting airways).

In companion studies conducted at the CNPRC, it has been shown that exposure of pregnant monkeys to BPA disrupts development of fetal ovaries, potentially causing birth defects and reproductive problems that would not emerge for a generation (Link); and that BPA also affects several developmental parameters of the mammary gland of rhesus monkeys, including some that are relevant to breast cancer risk in humans (Link).

The study of BPA in a primate model is critical because the rhesus monkey has estrogen levels as well as reproductive and developmental processes that are similar to humans.

Fragranced consumer products: effects on asthmatics

WAF Salutes Anne Steinemann, Department of Infrastructure Engineering, Melbourne School of Engineering, The University of Melbourne, Melbourne, VIC 3010 Australia

Fragranced consumer products, such as cleaning supplies, air fresheners, and personal care products, can emit a range of air pollutants and trigger adverse health effects. This study investigates the prevalence and types of effects of fragranced products on asthmatics in the American population. Using a nationally representative sample (n?=?1137), data were collected with an on-line survey of adults in the USA, of which 26.8% responded as being medically diagnosed with asthma or an asthma-like condition.

Results indicate that 64.3% of asthmatics report one or more types of adverse health effects from fragranced products, including respiratory problems (43.3%), migraine headaches (28.2%), and asthma attacks (27.9%). Overall, asthmatics were more likely to experience adverse health effects from fragranced products than non-asthmatics (prevalence odds ratio [POR] 5.76; 95% confidence interval [CI] 4.34–7.64). In particular, 41.0% of asthmatics report health problems from air fresheners or deodorizers, 28.9% from scented laundry products coming from a dryer vent, 42.3% from being in a room cleaned with scented products, and 46.2% from being near someone wearing a fragranced product. Of these effects, 62.8% would be considered disabling under the definition of the Americans with Disabilities Act. Yet 99.3% of asthmatics are exposed to fragranced products at least once a week. Also, 36.7% cannot use a public restroom if it has an air freshener or deodorizer, and 39.7% would enter a business but then leave as quickly as possible due to air fresheners or some fragranced product. Further, 35.4% of asthmatics have lost workdays or a job, in the past year, due to fragranced product exposure in the workplace. More than twice as many asthmatics would prefer that workplaces, health care facilities and health care professionals, hotels, and airplanes were fragrance-free rather than fragranced. Results from this study point to relatively simple and cost-effective ways to reduce exposure to air pollutants and health risks for asthmatics by reducing their exposure to fragranced products.

Introduction

Fragranced consumer products pervade society and emit numerous volatile organic compounds, such as limonene, alpha-pinene, beta-pinene, acetaldehyde, and formaldehyde (Steinemann 2015; Nazaroff and Weschler 2004), and semi-volatile organic compounds, such as musks and phthalates (Weschler 2009; Just et al. 2010). However, ingredients in fragranced products are exempt from full disclosure on product labels or safety data sheets (Steinemann 2015), limiting awareness of potential emissions and exposures. Fragranced products have been associated with a range of adverse health effects including work-related asthma (Weinberg et al. 2017), asthmatic exacerbations (Kumar et al. 1995; Millqvist and Löwhagen 1996), respiratory difficulties (Caress and Steinemann 2009), mucosal symptoms (Elberling et al. 2005), migraine headaches (Kelman 2004), and contact dermatitis (Rastogi et al. 2007; Johansen 2003), as well as neurological, cardiovascular, cognitive, musculoskeletal, and immune system problems (Steinemann 2016).

This article investigates specifically the effects of exposure to fragranced products on asthmatics in the US population. In addition to health impacts, it also investigates societal access, preferences for fragrance-free environments, awareness of fragranced product emissions, and implications for air quality and health. It compares results from the sub-population of asthmatics with non-asthmatics, as well as with the general US population, as reported in Steinemann (2016). The study provides important data on the extent and severity of the problem, pointing to opportunities to reduce the adverse health, economic, and societal effects by reducing exposure to fragranced products.

Methods

A nationally representative on-line survey was conducted of the US population, representative of age, gender, and region (n?=?1137, confidence limit?=?95%, confidence interval?=?3%). The survey drew upon a large web-based US panel (over 5,000,000 people) held by Survey Sampling International, using randomized participant recruitment (SSI 2016). The survey instrument was developed and tested over a two-year period before full implementation in June 2016. The survey response rate was 95% (responses to panel recruitment 1201; screen-outs 13; drop-outs 46; completes 1137), and all responses were anonymous. The research study received ethics approval from the University of Melbourne. Details on the survey methodology are provided as a supplemental document.

This article extends and deepens the general population study of Steinemann (2016) by analyzing specifically the effects on asthmatics and compared to non-asthmatics and the general population. Of the general population surveyed, 26.8% responded as being medically diagnosed with either asthma (15.2%, n?=?173) or an asthma-like condition (12.5%, n?=?142) or both (26.8%, n?=?305). For the purposes of the article, the sub-population of “asthmatics” will be those medically diagnosed with asthma, an asthma-like condition, or both; the sub-population of “non-asthmatics” will be those in the general population other than asthmatics.

Survey questions investigated use and exposure to fragranced products, both from one’s own use and from others’ use, exposure contexts and products, health effects related to exposures, impacts of fragrance exposure in the workplace and in society, awareness of fragranced product ingredients and labeling, preferences for fragrance-free environments and policies, and demographic information.

Specific exposure contexts included air fresheners or deodorizers used in public restrooms and other environments, scented laundry products coming from a dryer vent, being in a room after it was cleaned with scented cleaning products, being near someone wearing a fragranced product, entering a business with the scent of fragranced products, fragranced soap used in public restrooms, and ability to access environments that used fragranced products.

Fragranced products were categorized as follows: (a) air fresheners and deodorizers (e.g., sprays, solids, oils, disks); (b) personal care products (e.g., soaps, hand sanitizer, lotions, deodorant, sunscreen, shampoos); (c) cleaning supplies (e.g., all-purpose cleaners, disinfectants, dishwashing soap); (d) laundry products (e.g., detergents, fabric softeners, dryer sheets); (e) household products (e.g., scented candles, restroom paper, trash bags, baby products); (f) fragrance (e.g., perfume, cologne, after-shave); and (g) other.

Health effects were categorized as follows: (a) migraine headaches; (b) asthma attacks; (c) neurological problems (e.g., dizziness, seizures, head pain, fainting, loss of coordination); (d) respiratory problems (e.g., difficulty breathing, coughing, shortness of breath); (e) skin problems (e.g., rashes, hives, red skin, tingling skin, dermatitis); (f) cognitive problems (e.g., difficulties thinking, concentrating, or remembering); (g) mucosal symptoms (e.g., watery or red eyes, nasal congestion, sneezing); (h) immune system problems (e.g., swollen lymph glands, fever, fatigue); (i) gastrointestinal problems (e.g., nausea, bloating, cramping, diarrhea); (j) cardiovascular problems (e.g., fast or irregular heartbeat, jitteriness, chest discomfort); (k) musculoskeletal problems (e.g., muscle or joint pain, cramps, weakness); and (j) other. Categories were derived from prior studies of fragranced products and health effects (Caress and Steinemann 2009; Miller and Prihoda 1999) and pre-tested before full survey implementation.

Fragranced product exposure

Among asthmatics, 99.0% are exposed to fragranced products at least once a week, from their own use (71.1% air fresheners and deodorizers; 85.9% personal care products; 78.4% cleaning supplies; 81.3% laundry products; 76.7% household products; 67.5% fragrance; 3.6% other). Further, 94.8% are exposed to fragranced products at least once a week, from others’ use. Combined, 99.3% of asthmatics are exposed to fragranced products through their own use, others’ use, or both. Among non-asthmatics, 98.1% are exposed to fragranced products at least once a week from their own use, 91.1% from others’ use, and 98.9% from either or both. Thus, asthmatics are more likely to be exposed to fragranced products, from their own use and others’ use and both, than non-asthmatics (POR, 1.66; 95% CI, 0.36–7.71).
Adverse health effects

Among asthmatics, 64.3% reported one or more types of adverse health effects from exposure to one or more types of fragranced products (43.3% respiratory problems; 27.2% mucosal symptoms; 28.2% migraine headaches; 19.0% skin problems; 27.9% asthma attacks; 15.1% neurological problems; 14.1% cognitive problems; 12.1% gastrointestinal problems; 9.8% cardiovascular problems; 11.1% immune system problems; 9.5% musculoskeletal problems; and 1.3% other). Among non-asthmatics, 23.8% reported one or more types of adverse health effects from exposure to one or more types of fragranced products (see Table ?Table2).2). Thus, among all types of health effects (excepting asthma attacks), asthmatics are more likely to be affected than non-asthmatics (POR 5.76; 95% CI, 4.34–7.64).

Of the 64.3% of asthmatics reporting adverse health effects from fragranced products, proportionately more males report adverse effects than females, relative to non-asthmatics (asthmatic 52.0% female, 48.0% male; non-asthmatic 60.1% female, 39.9% male) (POR 1.39; 95% CI, 0.93–2.97) (see Table ?Table3).3). Among all age groups, proportionately more asthmatics in age group 25–34 report adverse effects relative to non-asthmatics (asthmatic 69.7%; non-asthmatic 23.3%) (POR 7.59; 95% CI, 4.19–13.76). Among all gender and age groups, proportionately more males age 25–34 report adverse effects relative to non-asthmatics (asthmatic 83.3%; non-asthmatic 18.1%) (POR 22.65; 95% CI, 8.15–62.92).

Specific exposure contexts

Air fresheners and deodorizers were associated with health problems for 41.0% of asthmatics (54.4% respiratory problems, 39.2% asthma attacks, 29.6% mucosal symptoms, 36.8% migraine headaches, 15.2% neurological problems, 26.4% skin problems, and others), and for 12.9% of non-asthmatics (see Table ?Table4).4). Thus, asthmatics were more likely to experience adverse effects from air fresheners than non-asthmatics (POR 4.71; 95% CI, 3.47–6.39).

Scented laundry products coming from a dryer vent were associated with health problems for 28.9% of asthmatics (38.6% respiratory problems, 30.7% asthma attacks, 30.7% mucosal symptoms, 27.3% migraine headaches, 18.2% neurological problems, 25.0% skin problems, and others), and for 6.5% of non-asthmatics (see Table ?Table4).4). Thus, asthmatics were more likely to experience adverse effects from scented laundry products coming from a dryer vent than non-asthmatics (POR 5.84; 95% CI, 4.03–8.46).

Being in a room after it has been cleaned with scented products was associated with health problems for 42.3% of asthmatics (51.9% respiratory problems, 32.6% asthma attacks, 27.1% mucosal symptoms, 32.6% migraine headaches, 21.7% neurological problems, 19.4% skin problems, and others), and for 11.4% of non-asthmatics (see Table ?Table4).4). Thus, asthmatics were more likely to experience adverse effects from being in a room after it has been cleaned with scented products than non-asthmatics (POR 5.69; 95% CI, 4.16–7.77).

Being near someone wearing a fragranced product was associated with health problems for 46.2% of asthmatics (54.6% respiratory problems, 29.1% asthma attacks, 28.4% mucosal symptoms, 31.9% migraine headaches, 19.1% neurological problems, 17.0% skin problems, and others), and 15.3% of non-asthmatics (see Table ?Table4).4). Thus, asthmatics were more likely to experience adverse effects from being near someone wearing a fragranced product than non-asthmatics (POR 4.77; 95% CI, 3.56–6.40).

Exposure to fragranced products can trigger disabling health effects, according to criteria from the Americans with Disabilities Act (ADA 1990): “Do any of these health problems substantially limit one or more major life activities, such as seeing, hearing, eating, sleeping, walking, standing, lifting, bending, speaking, breathing, learning, reading, concentrating, thinking, communicating, or working, for you personally?” Among asthmatics reporting health problems, 62.8% reported that the severity of the health effect from fragranced product exposure was potentially disabling. Thus, asthmatics were more likely to report disabling health effects from fragranced products than non-asthmatics (POR 7.13; 95% CI, 5.11–9.95).
Ingredient disclosure and product claims

Among asthmatics, 41.3% were not aware that a “fragrance” in a product is typically a chemical mixture of several dozen to several hundred chemicals, 57.4% were not aware that fragrance chemicals do not need to be fully disclosed on the product label or material safety data sheet, and 58.0% were not aware that fragranced products typically emit hazardous air pollutants such as formaldehyde. Further, 64.3% of asthmatics, and 75.7% of non-asthmatics, were not aware that even so-called natural, green, and organic fragranced products typically emit hazardous air pollutants (28.9% of asthmatics and 15.7% of non-asthmatics were aware). However, 60.3% of asthmatics, and 60.1% of non-asthmatics, would not still use a fragranced product if they knew it emitted hazardous air pollutants.
Societal and workplace effects

Fragranced products can also present barriers for asthmatics in public places and the workplace. Among asthmatics, 36.7% are prevented from using the restrooms in a public place, because of the presence of an air freshener, deodorizer, or scented product. Also, 28.9% are prevented from washing their hands with soap in a public place, if the soap is fragranced. Further, 43.9% are prevented from going to some place because they would be exposed to a fragranced product that would make them sick. Notably, 39.7% report that if they enter a business, and smell air fresheners or some fragranced product, they want to leave as quickly as possible.

Significantly, 35.4% of asthmatics, and 7.7% of non-asthmatics, have become sick, lost workdays, or lost a job, in the past 12 months, due to fragranced products in their work environment. Thus, asthmatics were more likely to have lost workdays or lost a job due to illness from fragranced products in their work environment than non-asthmatics (POR 6.58; 95% CI, 4.65–9.30).

Fragrance-free policies receive a strong majority of support. Among asthmatics, 66.2% would be supportive of a fragrance-free policy in the workplace (compared to 16.1% that would not). Thus, more than four times as many asthmatics would prefer a fragrance-free workplace than fragranced. Also, 72.1% of asthmatics would prefer that health care facilities and health care professionals be fragrance-free (compared to 14.8% that would not). Thus, nearly five times as many asthmatics would prefer fragrance-free health care facilities and professionals than fragranced.

Among non-asthmatics, 48.3% would support a fragrance-free workplace (compared with 21.0% that would not), and among the general population, 53.1% would support a fragrance-free workplace (compared with 19.7% that would not). Thus, regardless of population, fragrance-free workplaces receive more than twice as many in support as not.

Asthmatics also strongly prefer fragrance-free airplanes and hotels. If given a choice between flying on an airplane that pumped scented air throughout the passenger cabin, or did not pump scented air throughout the passenger cabin, 63.6% of asthmatics would choose an airplane without scented air (compared to 24.9% with scented air). Similarly, if given a choice between staying in a hotel with fragranced air, or without fragranced air, 63.0% would choose a hotel without fragranced air (compared to 28.5% with fragranced air).

Among non-asthmatics, 57.6 and 52.9% would prefer fragrance-free airplanes and hotels, respectively (compared with 23.1 and 27.5% that would not) and among the general population, 59.2 and 55.6% would prefer fragrance-free airplanes and hotels, respectively (compared with 23.6 and 27.8% that would not). Thus, overall, more than twice as many asthmatics, as well as the general population, would prefer that airplanes and hotels were fragrance-free rather than fragranced.

Discussion

Asthma is a serious and increasing health condition, affecting an estimated 25 million Americans, and costing an estimated $56 billion annually in medical expenses, missed school and work days, and premature deaths (CDCP 2017a). Nearly 12 million Americans had an asthma attack in 2015, many of which could have been prevented (CDCP 2017b).

Results from this study show that asthmatics are profoundly, adversely, and disproportionately affected by exposure to fragranced consumer products. While non-asthmatics are also affected, asthmatics are more likely to experience adverse health effects from exposure (POR 5.76; 95% CI 4.34–7.64).

Of particular concern are involuntary exposures to fragranced products, such as in health care facilities and workplaces. Asthmatics are prevented from accessing public toilets, businesses, and workplaces due to adverse health effects from fragranced products. Further, 35.4% have lost workdays or a job, in the past year, due to fragranced product exposure in the workplace. More than twice as many asthmatics would prefer that workplaces, health care facilities, health care professionals, airplanes, and hotels were fragrance-free than fragranced.

Limitations of the study include the following: (a) data were based on self-reports, although a well-established method for survey research; (b) all possible products and health effects were not included, although the low percentages for responses in the “other” category indicates the survey captured the primary products and effects; (c) product emissions and exposures were not measured directly; (d) the cross-sectional design of the study, while useful for determining prevalence, provides data that represent just one point in time, limiting the analysis of risk factors, temporal relationships between exposures and effects, and trends in prevalence, and (e) only adults (ages 18–65) were included in the survey, which overlooks the effects of fragranced products on children (such as in day care facilities and schools) and on seniors (such as in retirement communities and assisted living facilities).

Results of this study provide strong evidence that fragranced consumer products can harm health for both asthmatics and non-asthmatics, with asthmatics more affected. Understanding why these products are associated with a range of health problems is a critical topic that requires further research. Fragranced products emit a range of volatile and semi-volatile organic compounds, some of which are associated with adverse health effects, but virtually none of which need to be disclosed (Steinemann 2009, 2015), thus limiting scientific inquiry and public awareness of potential exposures to problematic compounds. A broader mechanistic framework is needed to understand which ingredients, or combinations of ingredients, could be associated with the adverse health outcomes reported in this study. In the meantime, a prudent and practical approach, and one that would provide direct and immediate benefits, would be to limit exposure to fragranced consumer products.

Perfumes, Magazines and Severe Asthma

Perfumes Strips and Scents in Magazines “Negatively Affect Asthmatics and adverse respiratory reactions to perfumes says study. In honor of #AsthmaAwarenessWeek and #WorldAsthmaDay can we stop doing this?

Note from the World Asthma Foundation. This study dates back to 1994. How much education is needed to change behavior? Can we PLEASE stop this practice already? It’s 2020 and we all know this to be true already right? Just saying People @people magazine.

Background

Perfume- and cologne-scented advertisement strips are widely used. There are, however, very few data on the adverse effects of perfume inhalation in asthmatic subjects.

OBJECTIVES:

This study was undertaken to determine whether perfume inhalation from magazine scent strips could exacerbate asthma.

METHODS:

Twenty-nine asthmatic adults and 13 normal subjects were included in the study. Histories were obtained and physical examinations performed. Asthma severity was determined by clinical criteria of the U.S.National Heart, Lung, and Blood Institute (NHLBI). Skin prick tests with common inhalant allergens and with the perfume under investigation were also performed. Four bronchial inhalation challenges were performed on each subject using commercial perfume scented strips, filter paper impregnated with perfume identical to that of the commercial strips, 70% isopropyl alcohol, and normal saline, respectively. Symptoms and signs were recorded before and after challenges. Pulmonary function studies were performed before and at 10, 20, and 30 minutes after challenges.
RESULTS:

Inhalational challenges using perfume produced significant declines in FEV1 in asthmatic patients when compared with control subjects. No significant change in FEV1 was noted after saline (placebo) challenge in asthmatic patients. The percent decline in FEV1 was significantly greater after challenge in severely asthmatic patients as compared with those with mild asthma. Chest tightness and wheezing occurred in 20.7% of asthmatic patients after perfume challenges. Asthmatic exacerbations after perfume challenge occurred in 36%, 17%, and 8% of patients with severe, moderate, and mild asthma, respectively. Patients with atopic asthma had greater decreases in FEV1 after perfume challenge when compared with patients with nonallergic asthma.

CONCLUSIONS:

Perfume-scented strips in magazines can cause exacerbations of symptoms and airway obstruction in asthmatic patients. Severe and atopic asthma increases risk of adverse respiratory reactions to perfumes.

Toxicants and Asthma – Recognizing Health Advocates and Champions for Asthmatics Everywhere

Toxicants and Asthma – Recognizing Health Advocates and Champions for Asthmatics Everywhere

“Polycyclic aromatic hydrocarbons, or PAHs — Exposure can come from breathing car exhaust, fossil fuel combustion, cigarette smoke, and wood smoke, among other routes. The toxicants were linked to problems such as reduced birth weight, asthma, and lower IQ.” Frederica Perera, Ph.D., Renowned environmental health scientist.

On behalf of the Asthma community around the globe, the World Asthma Foundation (WAF) salutes Frederica Perera as she is being honored for pioneering research, community engagement.

The NIEHS Spirit Lecture Awardee collaborates with disadvantaged groups to study how chemicals affect children and other vulnerable people.

Renowned environmental health scientist Frederica Perera, Ph.D., delivered the 2020 NIEHS Spirit Lecture on Mar. 5. Her talk was titled “Translational Research to Prevent Environmental Threats to Children: From Chemicals to Climate Change.”

Perera is a Columbia University professor and the founding director of the school’s Center for Children’s Environmental Health, which is co-funded by NIEHS. Her work focuses on pregnant women, children, and minority groups, who can be especially vulnerable to pollution.

“She is internationally recognized as a pioneer in the field of molecular epidemiology as it relates to better understanding how problems in the environment can lead to adverse health effects and disease,” said NIEHS Acting Director Rick Woychik, Ph.D.
Early-life vulnerability

In the late 1970s, after learning about an environmental disaster in Minamata Bay, Japan, Perera became inspired to pursue a scientific career in environmental health.

“Women there had been eating fish that were very polluted by mercury from industrial sources,” she told the audience. “The women were fine, but their children had serious cerebral palsy-like symptoms and intellectual disorders.”

“There are 82 billion neurons in the average brain, but almost all were formed before we were born,” she said. “You can imagine how highly choreographed and complex this development is over a short time window, and how readily any external exposure — whether a physical toxicant or psychosocial stressor — could disrupt these processes.”

Health effects over time

At Columbia, Perera and her colleagues seek to understand how early-life chemical exposures affect children’s health and brain development, and they look for potential long-term problems. The scientists follow cohorts of mother-child pairs in New York City (NYC), Poland, and China, tracking health effects of various substances over time.

In NYC, participants come from low-income African-American and Dominican households. Some findings from that cohort include the following.

Chlorpyrifos — Prenatal exposure to this insecticide was associated with lower birth weight, memory problems, and Parkinson’s Disease-like changes.
Phthalates — Found in cosmetics and plastic packaging, these chemicals were linked to reduced IQ in children who had been exposed to high concentrations prenatally.
Polybrominated diphenyl ethers, or PBDEs — These flame retardants were linked to reduced IQ in children who had high concentrations at birth.
Polycyclic aromatic hydrocarbons, or PAHs — Exposure can come from breathing car exhaust, fossil fuel combustion, cigarette smoke, and wood smoke, among other routes. The toxicants were linked to problems such as reduced birth weight, asthma, and lower IQ.

Many factors at play

According to Perera, understanding the effects of such exposures often is complicated by other factors, including genetics, nutrition, socioeconomic status, and climate change. She said that despite that complexity, studying individual chemicals still is beneficial.

“Most diseases require a set of sufficient causes,” Perera explained. “If we can take one of those causes out, it would be possible to prevent a child from developing a disease. Environmental exposures, by their very nature, are preventable once we identify them as harmful.”

Perera said that lowering the risks of environmental exposures will require a mix of regulatory policies, market reforms, and better data on the health and economic benefits of pollution mitigation.
Special award

“It’s a real honor for me to have the privilege to introduce Dr. Perera as this year’s recipient of the NIEHS Spirit Lecture Award,” said Woychik.

The award recognizes outstanding women who balance their careers with public engagement, volunteering, and mentorship.

“She works with many different community groups to address the safety and health of children,” he said. “Dr. Perera is a fabulous communicator and is doing cutting-edge, exciting research.”

Asthma and Toxic Consumer Products Linked Says Study

Hormone Disruption and Asthma Found In Consumer Products, says National Work Group for Safe Markets

Press reports reflect that toxic chemicals linked to rising rates of endocrine disruption related disease were found in consumer products and reported in a peer reviewed article in Environmental Health Perspectives today. Silent Spring Institute tested cleaning products, cosmetics, sunscreens, shower curtains, air fresheners, and other household goods made by Colgate, Unilever, S.C. Johnson, Johnson and Johnson, Procter & Gamble, Seventh Generation, and Ecover and others.”Test results show conventional and ‘green’ products contain hidden toxic chemicals not on product labels; consumers have no way of avoiding them,” says Alexandra Scranton from Women’s Voices for the Earth, who conducted their own tests for hidden toxic chemicals in products.

Martha Arguello, with Physicians for Social Responsibility – Los Angeles, says: “Silent Spring used Battelle Labs in Ohio: they found 55 chemicals associated with endocrine disruption or asthma, including parabens, BPA, triclosan, and more. It’s not good science to assume that cumulative exposure to chemicals is safe.””This study found PVC products, including a pillow protector and shower curtain, contained high levels of toxic phthalate DEHP,” explains Mike Schade from Center for Health, Environment & Justice. “Phthalates, banned in toys, are widespread in many PVC products in schools and at home. Linked to asthma, impacts on brain development, and reproductive health problems in baby boys, safer cost-effective alternatives exist for our schools and homes.””Many products are targeted to women of color who suffer from high health disparities that are linked to endocrine disruptors in products. We hope studies like this inspire better policies and regulations,” says Janette Robinson-Flint from Black Women for Wellness. “Mothers shouldn’t have to be biochemists to protect themselves and their families.”

“Many folks tested positive for BPA and Triclosan in our human biomonitoring studies,” says Sharyle Patton, Director of the Biomonitoring Resource Center at Commonweal. “One has to wonder if rising rates of health problems are linked to these exposures.”Caroline Cox, Research Director, Center for Environmental Health, says, “These unnecessary, untested and unlabeled chemicals in dozens of products threaten our children’s and families’ health. It’s past time for federal action.””This is another example of the failure of federal law to protect workers and consumers,” said Sarah Doll from SAFER States, “States have been acting to protect consumers from toxic chemicals.”

Asthma and Fragrance Sensitivity Law Introduced

According to published reports, a New Hampshire legislature has introduced a House Bill 1444 that could mandate that state workers who interact with the public as a part of their job would be prohibited from wearing fragrances or scented products during business hours. If approved, the bill would take effect within 60 days.

Chemical Sensitivity in Asthmatics Established

In 2009, a study conducted by Caress and Anne Steinenmann at the University of Washington found that nearly a third of people with asthma also have chemical hypersensitivity, and more than a third reported irritation from scented products.

“The more you’re around, the more likely it is to cause an attack,” one of the authors said. “People with asthma, many of them should try to avoid artificially fragranced products.”
