Occurrence and distribution of bisphenol compounds in different categories of animal feeds used in China
2021
Abstract Bisphenol compounds (BPs) are of concern worldwide as potential environmental contaminants, and these chemicals may migrate into animal-derived foodstuffs from animal feeds. In this study, 12 BPs were analyzed in 7 varieties of animal feed groups totaling 203 samples collected from various provinces in China. 6 BPs were found in these feed samples, with a total detection frequency of 75.5%. The total concentration of all BPs (Σ6BPs) in each type of feed ranged from below the limit of detection to 75.3 ng g−1, with an overall mean value of 4.52 ng g−1. The frequency of BPs contamination and the Σ6BPs values were found to be higher in animal-based feeds (Pfrequency > 0.05, Pconcentration
