| 英文摘要 | The substantial application of organophosphate triesters (tri-OPEs) may lead to a concentration escalation of their major metabolites, organophosphate diesters (di-OPEs) in animal-derived and plant-derived animal protein supplement feeds (APFs). APFs are major food for raised animals and may bring OPEs into the food supply. In the present study, the concentrations of Sigma(8)di-OPEs in animal-derived and plant-derived APFs were in the range of 1.98-182 ng/g dw (average: 39.2 ng/g dw). Meat meal had the highest average concentrations of di-OPEs (52.1 ng/g dw), followed by blood meal (49.9 ng/g), feather meal (23.3 ng/g dw), and plant-derived feeds (18.3 ng/g dw). The concentrations of di-OPEs were at the same order of magnitude as those of tri-OPEs in APFs. Bis(1,3-dichloro-2-propyl) phosphate (BDCIPP) was the major contributor in blood meal, feather meal, and plantderived APFs, while dimethyl phosphate dominated in meat meal. The ratios of di-OPEs/tri-OPEs (R-di/tri) displayed large variability, ranging from 0 for the bis(2-chloroethyl) phosphate-tris(2-chloroethyl) phosphate pair to 175 for the BDCIPP-tris(1,3-dichloroisopropyl) phosphate pair, which indicated that the metabolism capacities and environmental sources for di-OPEs are diverse in APFs. Different R(di/tri )between APFs and similar food matrices implied that di-OPEs may have different environmental sources. The similar R(di/tri )values for some of the di-/tri-OPE pairs among APFs and dust samples indicated that dust may be a direct exogenous source of OPE exposure in some APF matrices. Future studies should simultaneously focus on tri- and di-OPEs, together of which may reflect the actual exposure to OPEs through the food supply. |
