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.

Key words: bifenthrin, litchi, residue behavior, risk assessment
