Good news: Blood lead levels in children resume their downward trend

Tom Neltner, Senior Director, Safer Chemicals

It is always worth keeping an eye on the latest U.S. data on blood lead levels in children. While no amount of lead is safe, it is nice to see lower levels reported in findings released by the Centers for Disease Control and Prevention (CDC) late last year.

In case you missed it, blood lead levels decreased among the children most exposed to the heavy metal during the most recent two-year cycle, according to a biomonitoring data report released by CDC.

The 2017-18 data comes from the CDC’s National Health and Nutrition Evaluation System (NHANES), and it is a key measure of overall progress towards reducing children’s exposure to lead from all sources.

In April 2019, we reported disturbing news that after six years of sustained and significant progress, the NHANES 2015-16 cycle showed blood lead levels (BLLs) of the most exposed children 1 to 5 years of age increased compared to the previous two years. We saw a similar trend for children 6 to 11 years of age in the 2015-16 data. At the time, we cautioned that the increase was not statistically significant because of the relatively small sample sizes – between 600 and 800 children in each age range – but was still worth watching.

Changes for the better: EPA looks out for workers in revised risk finding for HBCD

By Samantha Liskow, Lead Counsel, Health

EPA has started to fulfill its promise to take another look at many of the chemical risk findings made during the Trump Administration. First up was “HBCD,” a collection of flame retardants present in many goods, including building insulation, furniture, and electronics. In its revised risk determination for the chemical EPA proposed important changes that are needed to protect health and the environment and are required under TSCA, our main federal law on chemical safety.

We highlighted these positive steps in our comments to the agency and urged EPA to formalize these changes when it releases its final revised risk determination for HBCD and other chemicals undergoing reevaluation.

Here is a look at the changes EPA made: Read More »

EPA can incorporate cumulative impacts in its chemical assessments right now

By Maria Doa, Senior Director, Chemicals Policy, and Lariah Edwards, Ph.D., EDF-George Washington University Postdoctoral Fellow

EPA recently asked its Science Advisory Board to provide advice on how it can incorporate cumulative impact assessments into its decisions making and on research to support cumulative impact assessments. At a public meeting of the SAB on March 2, we highlighted several areas where EPA can incorporate cumulative impact assessments right now.

Cumulative impacts refer to the total burden from chemical and non-chemical stressors and their effect on health, well-being, and quality of life. EPA asked the SAB for advice in two areas: First, what research should the agency conduct to strengthen the methods used in cumulative impact assessments. Second, and somewhat more important, how can EPA start now to incorporate cumulative impact assessments into its decision-making using data that is currently available.

People living in communities are often exposed to multiple chemical and non-chemical stressors. When individuals are exposed to multiple chemicals that cause a particular type of harm, they do not experience the risks for each chemical separately from the other. Nor are these chemical burdens experienced in isolation from other non-chemical stressors a person may face, like nutritional deficiencies or psychosocial stress. Cumulative impact assessments consider the combination and impact of both types of stressors, and therefore are more reflective of real-life conditions.

EPA assessments and decision making should take into consideration this reality and move away as much as possible from the status quo of evaluating one source, one chemical, and one environmental medium. Read More »

Understanding PFAS: Why a broad, transparent PFAS Testing Strategy is needed

Maria Doa, Senior Director, Chemicals Policy; Lauren Ellis, Research Analyst; and Lariah Edwards, Post-Doctoral Fellow

EDF this week sent EPA a letter identifying opportunities for the agency to improve the effectiveness and transparency of its strategy for testing per- and polyfluoroalkyl substances (PFAS).

EPA unveiled its National PFAS Testing Strategy (Testing Strategy) last fall, laying out its plan to better understand the class of chemicals and inform its future regulatory efforts. PFAS are a large group of synthetic chemicals used to impart water, oil, grease, and stain resistance to various materials, and they are used in hundreds of everyday products, from water-proof clothing to grease-proof food packaging. By its own count, EPA says there are more than 12,000 individual PFAS.

In their letter to EPA, EDF analyst Lauren Ellis and post-doctoral fellow Lariah Edwards commended the agency for developing a strategy to address some of the significant data gaps that exist around PFAS and committing to use its authority under the Toxic Substances Control Act (TSCA) ‒ the country’s main chemical safety law ‒ to require manufacturers to provide toxicity data on the chemicals.

As the letter points out, however, in its current state, the Testing Strategy lacks sufficient detail and is too narrow to fulfill the agency’s intended purpose to understand and regulate PFAS in a way that is protective of both human health and the environment. Read More »

The new FDA Commissioner has a full plate; here are three steps he can take to keep focused on food safety too

Tom Neltner, Senior Director, Safer Chemicals.

The U.S. Senate today voted to return Robert Califf to the role of FDA Commissioner, bringing needed leadership to an agency that plays a vital role in protecting public health. 

While Dr. Califf faces historic challenges in the form of the COVID-19 pandemic and the opioid epidemic, he also has a tremendous opportunity to elevate the agency’s important role in protecting the public from unsafe chemicals in food. 

We put together a list of three things Dr. Califf and the FDA have the authority to do right now to keep problematic chemicals out of our food:  Read More »

Did your kids have a hyper holiday? Why those vibrantly colored treats need a warning label

Terry Hyland, Communications Manager

Many parents have experienced that foreboding sense of what might come next as they watch their child indulge in a decadent treat at a holiday gathering or birthday party. All that sugar means things are about to get a little crazy, right?

While sugar has its own issues, perhaps the source of that burst of hyperactivity is another ingredient: the synthetic dyes that brighten many of our sweet treats, and many of the not-so-sweet ones too.

Last year, California government scientists at the Office of Environmental Health Hazard Assessment (OEHHA) released a report finding that commonly used synthetic food dyes can lead to hyperactivity and other neurobehavioral problems in children, with some reacting very strongly to relatively small amounts of colorants. Children’s exposure is also higher compared to adults.

That stands to reason. According to OEHHA, the most common food items associated with food dye exposures include icings, fruit-flavored and juice drinks, sodas, and breakfast cereals. And it is not only the more than 6 million children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) that may be particularly sensitive to synthetic dyes; kids without pre-existing behavioral disorders can also be affected.
