US environmental agency says 1,3-butadiene is harmful for some industry workers, but not for the environment or those living near plants using it
The US Environmental Protection Agency (EPA) has concluded that the rubber ingredient 1,3-butadiene, which it classifies as a human carcinogen, might present health risks to industrial workers but poses no threat to the environment or those living near facilities where the chemical is used. The conclusions, announced on New Years Eve, contrast with regulations put in place during Joe Biden’s presidency that required companies to monitor levels of the chemical in the air outside their plants.
