摘要： 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 (Sigma(6)BPs) 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 Sigma(6)BPs values were found to be higher in animal-based feeds (P-frequency > 0.05, P-concentration < 0.01) than in plant-based feeds. BPA and BPS were the predominant BPs in these feed samples, accounting for (on average) 63.9% and 24.6% of the total BPs, respectively. Overall, the mean concentrations of BPA in these animal feeds were much lower than the legal limits set by China and European Union, implying a low direct risk to both animal health and animal-derived food safety. However, the evident risk of the contamination of various animal-derived food items with BPs passed through the feed chain merits further investigation. (c) 2021 The Authors.
