Apple is facing a lawsuit in California over allegations that its Apple Watch bands contain PFAS, or per- and polyfluoroalkyl substances, which are linked to health risks, including cancer. The lawsuit claims that Apple was aware of the harmful effects of these chemicals yet continued to sell the products. Studies indicate that PFAS can be easily absorbed through the skin, raising concerns about their potential impact on users' health. In response, Apple maintains that its Watch bands are safe for consumers. This legal challenge comes amid increasing scrutiny of PFAS in various consumer products, with Canadian companies required to report on the presence of these chemicals in their supply chains by January 29.
