Toxic Dust Threatens California Salmon Population, Lawmaker Seeks Solution

Assemblymember Diane Papan (D-San Mateo) recently introduced legislation — AB 1798 — that would mandate the state’s leading transportation agency to devise a plan for naturally removing the toxic tire particles, known as 6PPD-quinone, before they slip into waterways and kill fish. While the state has already asked the tire industry to develop alternatives for the chemicals in every tire sold in California, Papan’s plan seeks to clean up the pollution from the cars already on the road.
