First things first: vinyl chloride data updates and our case for stronger evaluations

NOTE: This is the first of a series about EPA’s prioritization of existing chemicals. 

 What Happened? 

EPA recently announced it had initiated the prioritization process for five chemicals for upcoming risk evaluation.  One of the chemicals, vinyl chloride, is a highly toxic chemical known to cause liver toxicity and liver cancer in humans. The other four chemicals are also carcinogens and cause other toxic effects such as harms to pregnant women and infants.  

We have added these five chemicals to our Chemical Exposure Action Map. Our map shows releases of TSCA high priority chemicals, focusing on three major categories of health harms from cumulative exposure to these chemicals: cancer, developmental harm, and asthma.  Why It Matters 

Prioritizing a chemical as high priority is a key step in the process of evaluating and managing its unreasonable risks under…
