Are “safe” exposure levels really “safe”?

Health risk assessment is the method that regulators use to determine whether chemicals in the environment pose a risk to people’s health and how much exposure to the chemical produces these effects. Unfortunately, current human health risk assessments don’t capture everyone’s risk level. Our recent paper, Application of Probabilistic Methods to Address Variability and Uncertainty … Continue reading Are “safe” exposure levels really “safe”?

With chemicals that can harm you, one size does not fit all

When the U.S. Environmental Protection Agency (EPA) evaluates chemical risks, it assumes for the most part that we are all the same. Or, rather, that some of us might be a little bit more sensitive than others. Ten times more sensitive, to be specific. But that’s not exactly true. When it comes to chemicals in … Continue reading With chemicals that can harm you, one size does not fit all

The weak link: gaps in exposure assessments

Protecting the public from the most concerning environmental chemicals and contaminants involves many individual steps. For example, when an agency like the US EPA or FDA evaluates a chemical used in consumer products, they want to evaluate:  the hazards associated with that chemical,   how that chemical causes harm, how much of the chemical is released … Continue reading The weak link: gaps in exposure assessments

Scientists recommend changes to chemical regulatory process

As Chemicals Proliferate in the Environment, a Science-Based Approach Is Needed to Protect Human Health With chemical production and use on the rise, and continued evidence that many chemicals in everyday products are linked to health problems such as cancer, infertility, and neurodevelopmental conditions, an interdisciplinary group of scientific experts said changes are urgently needed … Continue reading Scientists recommend changes to chemical regulatory process

EPA’s failure to properly implement TSCA puts lives at risk

In the 40 years between enactment of the original Toxic Substances Control Act (TSCA) in 1976 and its 2016 amendments, EPA regulated less than 1% of the existing chemicals on the market. EPA was even unable to ban cancer-causing chemicals like asbestos, part of the reason Congress updated TSCA to make it easier for regulators … Continue reading EPA’s failure to properly implement TSCA puts lives at risk

EPA must improve its TSCA systematic review method, scientific review says again

Six years have passed since Congress updated the Toxic Substances Control Act (TSCA), yet EPA still does not have an appropriate method for conducting systematic reviews of chemical risks - the method by which EPA evaluates potential health harms - which is critical to protecting the public’s health. This is the clear conclusion taken from … Continue reading EPA must improve its TSCA systematic review method, scientific review says again

Whether or not you’ve heard of the chemical bisphenol A, better known as BPA, studies show that it’s almost certainly in your body. BPA is used in the manufacturing of products like plastic water bottles, baby bottles, toys and food packaging, including in the lining of cans. BPA is one of many harmful chemicals in … Continue reading Decades of research document the detrimental health effects of BPA – an expert on environmental pollution and maternal health explains what it all means

EPA can require chemical companies to provide data on PFAS risks. Why isn’t it?

Scientist examining toxic water samples

In the recent ProPublica article, “She’s Supposed to Protect Americans from Toxic Chemicals. First, She Has to Fix Trump’s Mess and Decades of Neglect,” Dr. Michal Freedhoff, PhD, EPA’s head of the Office of Chemical Safety and Pollution Prevention (OCSPP) said: “You can’t ask companies to spend a bunch of money producing data that already … Continue reading EPA can require chemical companies to provide data on PFAS risks.
