Pesticide adjuvants (PAs) are important components of pesticide products. However, limited information is available regarding their occurrences in foodstuffs. Herein, eight common-used PAs were investigated in vegetables in North China in 2014-2016. The residue levels of total PAs in vegetables from markets and farms were 500 and 661 μg/kg, respectively. The highest residues of total PAs were found in cauliflowers (average: 1.53 × 10 μg/kg, market vegetables) and spinaches (average: 3.72 × 10 μg/kg, farm vegetables), respectively. In addition, Tristyrylphenol ethoxylates (TPE) dominated the total 8 PAs concentrations in most vegetable species. Moreover, the risk assessment showed that the human health risks associated with TPE and nonylphenol (NP) exposure via vegetables for adults were acceptable, and the estimated daily intakes (EDIs) of other six PAs were in the range of <0.010-0.89 μg/kg bw/day, which were less likely to pose a threat to human health.
农药助剂（PAs）是农药产品的重要组成部分。然而，关于其在食品中的存在情况的信息有限。本研究于 2014-2016 年调查了华北地区蔬菜中的 8 种常用农药助剂。市场蔬菜和农场蔬菜中总农药助剂的残留水平分别为 500 和 661μg/kg。总农药助剂残留量最高的是花椰菜（平均：1.53×10μg/kg，市场蔬菜）和菠菜（平均：3.72×10μg/kg，农场蔬菜）。此外，三苯乙烯基苯酚乙氧基化物（TPE）在大多数蔬菜物种中的总 8 种农药助剂浓度中占主导地位。此外，风险评估表明，成年人通过蔬菜接触 TPE 和壬基酚（NP）所带来的健康风险是可以接受的，其他 6 种农药助剂的估计每日摄入量（EDI）处于<0.010-0.89μg/kg bw/day 范围内，不太可能对人体健康构成威胁。
