They biodegrade（生物降解）very slowly over time and can persist over thousands of years in the environment, a property that has led to them being known as “forever chemicals”. They are linked to various health issues, including thyroid disease, liver damage, kidney cancer and so on. Furthermore, these chemicals are used in everyday items, such as outdoor clothing and non-stick pans, to make them water and heat-resistant. For a more in-depth analysis, the research team purchased 39 different brands of drinking straws made from five materials — paper, bamboo, glass, stainless steel and plastic, and then conducted two rounds of testing for PFAS. They found that most brands (69%) contained PFAS, with 18 different PFAS detected in total. In paper straws, PFAS was detected in 90% of the brands tested. PFAS was also detected in 80% of brands of bamboo straws, 75% of plastic straw brands and 40% of glass straw brands. They were not detected in any of the five types of steel straws tested. “The presence of PFAS in paper and bamboo straws shows they are not necessarily biodegradable,” says Dr. Groffen. “We did not detect any PFAS in stainless steel straws, so I would advise consumers
