Abstract:
Bisphenol analogues (BPs) are widely applied in varying consumer products. Many studies have reported their presence in indoor dust samples from China. However, the differences in occurrence and concentration profiles of BPs in indoor dust between rural and urban areas are still not well characterized. In this study, eight BPs were measured in 60 indoor dust samples collected from rural and urban districts of Hangzhou, China. Bisphenol A (BPA; mean 1.8 μg/g, range 0.20-7.2 μg/g) was the predominant BP in indoor dust samples, accounting for mean 57% of the total BP (∑BP) concentration, followed by bisphenol S (BPS; 0.58 μg/g,
