Bisphenol A diphenyl phosphate is a halogen-free flame retardant used plastics. It is used in polymer blends of engineering plastics, such as PPO/HIPS and PC/ABS, [1] which are commonly used to make casing for electrical items like TVs, computers and home appliances. It is formed by the transesterification of bisphenol A with triphenyl phosphate.
The researchers sampled 39 brands of straws made of paper, bamboo, glass, stainless steel and plastic. Of those, 27 were found to contain PFAS, though the concentrations were low.
