| 摘 要： | 本研究开展了4%联苯菊酯悬浮剂在荔枝上的残留检测,然后根据残留检测结果和我国的膳食消费量评估了联苯菊酯按照推荐方式施用后对我国不同类型人群的急慢性膳食暴露风险,还评估了对土壤非靶标生物蚯蚓的环境风险。结果表明:联苯菊酯在荔枝全果中的半衰期为2.6～6.9 d,在土壤中的半衰期为11.5～13.8 d;按照推荐施药方式(施药剂量:1000倍液,施药次数:2次,施药间隔期:10 d,推荐安全间隔期:21 d)在荔枝上施用不会对我国消费者存在急慢性膳食暴露风险,而且对土壤非靶标生物蚯蚓也是低风险。

| Abstract: | Residue experiments of 4% bifenthrin suspending agent in litchi were conducted in this study. The acute and chronic dietary exposure risks to different subgroups of Chinese and the environment risks to non-target organism earthworm were assessed according to the results of the experiments. Results showed the half life of bifenthrin in litchi and soil was 2.6-6.9 d and 11.5-13.8 d, respectively, the acute and chronic dietary exposure risks to different subgroups were low after spraying at the dosage of 1000 times for twice with 10 d intervals and PHI of 21 d, and the environment risks to non-target organism earthworm were also low. |
