Protecting our most TENDR: Experts Call for Reducing Children’s Exposure to Neurodevelopmental Toxicants

Jennifer McPartland, Ph.D., is a Senior Scientist with the Health Program.

Today, a prominent group of health care professionals, scientists, and advocates including EDF published a consensus statement highlighting the significant scientific evidence linking impacts on children’s brain development to exposures to certain toxic chemicals.

Beginning in utero, children are particularly vulnerable to the effects of toxic chemicals and exposures occurring early in development can result in lasting, later life outcomes. The TENDR (Targeting Environmental NeuroDevelopmental Risks) Consensus Statement, published in Environmental Health Perspectives, outlines troubling statistics on the high incidences of neurological disorders in children, ranging from ADHD and other behavioral disorders to reduced IQ. Some  of the exemplar chemicals featured in the statement include the PBDE flame retardants, phthalates, air pollution, and lead—all harmful chemicals that EDF has blogged about and been working to address through policy improvements, better exposure monitoring tools, and market action.

A number of factors contribute to neurological disorders, but exposure to neurodevelopmental toxicants is preventable. The TENDR statement calls on government, the business community, and health professionals to all redouble efforts to reduce children’s exposures to neurodevelopmental toxicants. We applaud the broad set of individuals and organizations that came together to develop and support the TENDR consensus statement, and hope that it will catalyze actions to protect children from chemicals that adversely impact their brain development.

Wearable wristbands detect flame retardants

Lindsay McCormick is a Research Analyst.

Chemical and Engineering News (C&EN) recently featured an article on simple, silicone wristbands used to detect chemicals in the everyday environment. Developed by researchers from Oregon State University, these wearable wristbands act like sponges to absorb chemicals in the air, water and everyday consumer products. EDF sees exciting promise in this technology, and has begun using this tool to make the invisible world of chemicals, visible.

The C&EN article highlighted two new studies which used the wristbands to characterize flame retardant exposure – the first two published studies to demonstrate that the wristband technology can be effectively used for this purpose.

There is good reason to explore flame retardant exposure. A 1975 California flammability standard resulted in the addition of flame retardant chemicals to hundreds of millions of foam products in the U.S. including couches and foam baby products. As furniture and other products get old and breakdown, flame retardants are released into surrounding air and settle in the dust in our homes. Evidence from the CDC’s National Biomonitoring Program demonstrates that 99% of people tested have polybrominated diphenyl ether (PBDE) flame retardants in their body, and other studies indicate that children are more highly exposed to flame retardants than adults.

EPA simply must do better on transparency and chemical data access

Richard Denison, Ph.D., is a Lead Senior Scientist.  Lindsay McCormick is a Research Analyst.

[This is Part Two of a two-part series.  Here is a link to Part One.]

Under this Administration, EPA has taken some significant steps toward reversing decades of passivity and secretive practices that evolved under the Toxic Substances Control Act (TSCA) when it came to transparency in decision-making and providing access to chemical information it obtains or develops.

Several initiatives undertaken through what EPA originally termed its enhanced chemicals management program have developed and laid out clearer policies and procedures in areas such as:  chemical prioritization (leading to its Work Plan Chemicals Program); enforcing limits on and reviewing confidential business information (CBI) claims asserted by industry (leading to its declassification of hundreds of previously hidden chemical identities and health and safety studies that companies had illegitimately claimed confidential or no longer merited protection from disclosure, but that EPA had not bothered to review or challenge before now); and EPA’s regulatory efforts to reduce risks from exposures to toxic chemicals (leading to its Action Plans on high-concern chemicals and proposed follow-up activities for work plan chemicals where assessments – the first completed in decades – have identified significant risks).

EPA has also developed new databases and tools to provide greater access to chemical information in its possession and regulatory decisions and supporting documents it develops; these include the Chemical Data Access Tool and ChemView.

All of these efforts are still very much works in progress but hold significant potential to improve transparency, information access and risk reduction.

But sometimes the Agency does something that makes clear just how far it still has to go in these respects.  Unfortunately, a case in point is its recent effort toward assessing risks of a cluster of flame retardant chemicals, the brominated phthalates, some of which are in wide use and are showing up in everything from house dust to dolphins.   Read More »

Very little, very late: EPA still lacks data on safety of widely used flame retardant chemicals

Lindsay McCormick is a Research Analyst.  Richard Denison, Ph.D., is a Lead Senior Scientist.

[This is Part One of a two-part series.  Here is a link to Part Two.]

Last summer, EPA released a Problem Formulation and Data Needs Assessment describing the inadequacy of data available to conduct risk assessments on a group of brominated phthalate flame retardants – two of which are major components in widely used Firemaster products. 

This is the first of two blog posts on the comments EDF recently submitted to EPA on this document.  In this post, we discuss the growing public health and environmental concerns over use of Firemaster products and the recommendations we made to EPA on steps it needs to promptly take to address these concerns.  In our second post, we’ll lay out our serious concerns about the lack of transparency, limited data access, and allowance of unwarranted confidentiality claims that our review of EPA’s document brought to light.

 

First, a brief history

In the mid-2000s, Great Lakes Chemicals Corporation (now Chemtura) agreed to phase out production of polybrominated diphenyl ether (PBDE) flame retardants due to mounting evidence of their health effects and their persistence and accumulation in people and the environment.  Soon after, the use of the company’s replacement Firemaster products skyrocketed.

The two main components of Firemaster products, 2-Ethylhexyl 2,3,4,5- tetrabromobenzoate (TBB) and bis(2-Ethylhexyl) -3,4,5,6- tetrabromophthalate (TBPH), are  high production volume (“HPV”) chemicals – each produced at more than one million pounds annually.

Unfortunately, use of these chemicals rose to such levels – replacing PBDEs in consumer products like polyurethane foam-based furniture and electronics – without sufficient data and review to establish their safety.   Read More »

Advancing the ball while minding the gaps: EDF’s comments on EPA’s risk scoping documents for flame retardant chemicals

Lindsay McCormick is a Research Analyst.

Until June 2014, EPA had not completed a chemical risk assessment under its Toxic Substances Control Act (TSCA) authority in 28 years.  Since then, EPA seems to have been somewhat picking up the pace: Over the past year and a half EPA has completed four additional risk assessments through the TSCA Work Plan Chemical Program, which is designed to assess the risks of priority chemicals currently on the market.

Recently, EPA initiated its assessment process for the next set of Work Plan chemicals, including three “clusters” of flame retardant chemicals.  We fully support EPA’s current efforts to assess the risks of these flame retardants – with the end goal of managing identified risks – and have provided quite extensive comments on EPA’s initial scoping documents.  In this post, I’ll highlight some of our comments and recommendations; see the links at the end to access the comments themselves.   Read More »

Flame retardants impair normal brain development: Even more evidence, still no action

Jennifer McPartland, Ph.D., is a Health Scientist.

Today a new study was published linking fetal exposure to certain flame retardants called polybrominated diphenyl ethers (PBDEs) with cognitive and behavioral effects that develop later in childhood.  While the specific findings in this study are new, the link between these types of neurodevelopmental effects and exposure to PBDEs is not. 

Numerous scientific studies and governmental bodies across the globe have flagged the health effects of PBDEs.  At the same time, current proposals by the Environmental Protection Agency (EPA) to better understand the hazards and sources of certain PBDEs remain in limbo.  Read on to learn more about today’s new study on PBDEs and the stalling of EPA initiatives to help protect us from exposure to them.  Read More »
