Prenatal exposure to PFAS and PBDE chemicals linked to greater risk of preterm birth

Prematurity is the second leading cause of death among infants in the United States and exposure to PFAS and PBDEs (chemicals in non-stick pans, water-repellent fabric, and furniture foam) during pregnancy is associated with an increased risk of preterm birth. But while there is extensive research on some of these chemicals, the effects of other, … Continue reading Prenatal exposure to PFAS and PBDE chemicals linked to greater risk of preterm birth

Holding EPA accountable for its scientific methods

House Committee on Science, Space & Technology Chair Rep. Eddie Bernice Johnson sent a letter to EPA chief Michael Regan asking the Agency when it will update its systematic review methodology – the method used to evaluate chemicals risks - under the Toxic Substances Control Act (TSCA). PRHE has been working to ensure EPA uses validated systematic review … Continue reading Holding EPA accountable for its scientific methods

World’s OBGYNs say climate crisis threatens human reproduction and urge action on fossil fuels

The climate crisis has become a public health emergency that disproportionately affects pregnant people, children, those from disadvantaged and marginalised communities, and people of colour, including Black, Brown and Indigenous people.

Behind the Scenes: Meet 3 young scientists working to protect you from toxic chemicals

In high school, Swati Rayasam thought she would study architecture or Russian literature. Then a friend almost lost his leg to an antibiotic resistant staph infection and she switched gears into science. Today she monitors EPA’s implementation of the updated Toxic Substances Control Act (TSCA) - the law that governs chemicals in commerce - for … Continue reading Behind the Scenes: Meet 3 young scientists working to protect you from toxic chemicals

Environmental contaminants interfere with our metabolism

We know that all humans are exposed to some mixture of contaminants through consumer products and contaminated food, air, and water, but how do we determine which ones interfere with our metabolism and compromise our health? Scientists develop analytical methods to identify and measure the quantities of chemical compounds in people and in the environment. … Continue reading Environmental contaminants interfere with our metabolism

Running out the TSCA clock could give hazardous chemicals a “pass”

Is EPA giving itself enough time to evaluate the safety of chemicals and protect health? Or is the Agency’s planned process to gather data for risk evaluations on chemicals under the Toxic Substances Control Act (TSCA), called the “Tiered Data Reporting Rule,” giving harmful substances a “pass” by running out the clock? When TSCA was … Continue reading Running out the TSCA clock could give hazardous chemicals a “pass”

How does wildfire smoke affect pregnancy outcomes?
