| 摘 要： | 为明确草莓中施用噻苯隆的作用、噻苯隆在草莓和土壤中的残留行为及其产生的膳食摄入风险,开展了规范残留试验并监测了噻苯隆对草莓生长和品质的影响,同时对草莓中噻苯隆残留带来的急性膳食摄入风险进行了评估。噻苯隆在草莓和土壤中的消解符合一级动力学方程,在草莓中的半衰期为1.31-1.44 d,土壤中的残留半衰期为1.69-1.87 d,草莓中正常收获期的最大残留量为0.0023 mg/kg,土壤中的最终残留量均低于方法定量限。噻苯隆可增加草莓单果重,提高产量,可溶性糖含量也有所升高,推荐使用剂量为2 mg/L浓度喷施2次。草莓中噻苯隆残留对普通人群和儿童的膳食摄入暴露量分别为0.023和0.043 μg/kg bw/d,仅占ARfD的0.058-0.11%,均在可接受范围内,说明草莓中噻苯隆残留带来的膳食摄入风险极低。
