"West Coast tribes prompt US regulators to investigate car-tire chemical's impact on salmon"
US regulators have agreed to review the use of a chemical called 6PPD, commonly used in tire manufacturing, after a petition from three West Coast Native American tribes called for a ban due to its harmful effects on salmon populations. The tribes argue that the chemical, which is washed into bodies of water through storm runoff, poses an "unreasonable threat" to their waters and fisheries. The decision to grant the petition is the first step towards banning the chemical, with tire manufacturers already seeking alternatives. The tribes have long fought to protect the dwindling fish population from various threats, including climate change and pollution.
