Atmospheric oxidation of the anti-degradation compounds 6PPD and DPPD that are present in tire wear particulates produce approximately 90 compounds that are found in near-road environmental air samples. This mixture caused inflammation and death of human macrophages, and was more toxic than 6PPD-quinone.

New study shows atmospheric compounds formed from tire wear may pose human health risk

Tire rubber contains antioxidant chemicals, most notably 6PPD and DPPD, that are released into the air as tiny particles during normal driving. A single compound formed from 6PPD, known as 6PPD-quinone was previously shown to be implicated in the death of coho salmon in urban waterways, but the broader atmospheric chemistry and potential human health impacts of these compounds have remained largely unexplored until now.

Bandenfabrikanten voor de rechter wegens massale sterfte van zalmen langs hele westkust van Amerika

Michelin, Bridgestone, Pirelli en tien andere internationale bandenfabrikanten moesten zich deze week voor de rechter in San Francisco verantwoorden wegens het vervuilen van rivieren met een chemisch additief uit autobanden.

A 2020 paper revealed the cause of mortality: a chemical called #6PPD that is added to tires to prevent their cracking and degradation. When 6PPD, which occurs in tire dust, is exposed to ground-level ozone, it’s transformed into multiple other chemicals, including 6PPD-quinone, or 6PPD-q. The compound is acutely toxic to four of 11 tested fish species, including coho salmon.

Toxic dust from tires is flowing into waterways from roads and highways, where it kills some species of salmon and trout.

Assemblymember Papan recently introduced legislation to remove these toxic tire particles before they slip into waterways and kill fish:

California salmon are in decline, but lawmakers believe they have a solution to the part of the problem: cleaning toxic tire dust from storm runoff that kills fish.
