英文摘要	Animal protein supplement feeds (APFs) are important raw feed materials for livestock. APFs might be susceptible to organophosphate esters (OPEs) but have not been paid attention yet. In the present study, animal-derived (meat meal, feather meal, and blood meal) and plant-derived APFs were all found to contain detectable levels of OPEs, with 16 target OPEs ranging from 12.6 ng/g dry weight (dw) to 301 ng/g dw. Meat meal contained the highest OPE level (mean: 117 +/- 75.6 ng/g dw), followed by feather meal (54.6 +/- 30.0 ng/g dw), plant-derived feed (41.9 +/- 16.0 ng/g dw), and blood meal (28.0 +/- 12.0 ng/g dw). Considering its widespread consumption, plant-derived APFs might be an important source of OPE exposure for livestock. Dust adhesion contributed to OPE contamination both in feather meal and plant-derived APFs. Congener patterns varied among the different APFs. Tris(2-chloroisopropyl) phosphate dominated in the plant-derived feed and blood meal, while tris(2-chloroethyl) phosphate and triphenyl phosphate were the major contributors in meat meal and feather meal, respectively. Tributyl phosphate and tri-iso-butyl phosphate were found to be statistically correlated in all APFs (p < 0.01), indicating their similar behavior and common sources. The protein-associated transport pathways of OPEs need to be studied separately for different protein matrices in the future.
