[h=1]DISCOVERY OF TOXIC CHEMICAL IN TIRES SPURS SCIENTIFIC AND REGULATORY INTEREST[/h]
"[FONT="]A chemical known as 6-PPD is often added to tires to extend their useful life. The additive works by reacting with ground-level ozone before the ozone can damage the tire’s rubber. The chemical reaction produces 6-PPD-quinone, a compound apparently never studied until now. The newly discovered compound is estimated to be more than 100 times as toxic as the parent compound, 6-PPD."[/FONT]
