The Enrichment and Distribution of Trifloxystrobin in Medaka Fish
2020
In order to evaluate the safety of trifloxystrobin in environment and non-target organisms, the enrichment and distribution of trifloxystrobin in Medaka (Oryzias latipes ) were studied in this experiment. Medaka were exposed in the water containing 0.1 μg/L, 1 μg/L, 10 μg/L and 100 μg/L trifloxystrobin continuously for 21 days. The results indicated that in female, the concentration order was as follows: fat > liver > intestine > gonad > flesh; in male, the concentration order was as follows: fat > intestine > liver > flesh in the low concentration exposure group with 0.1 μg/L and 1 μg/L, while the concentration order was as follows: fat > liver > intestine > flesh in the high concentration exposure group with 10 μg/L and 100 μg/L. This study provides important data support and theoretical basis for predicting the behavior of trifloxystrobin in the environment, evaluating the environmental safety of trifloxystrobin and guiding the use of drugs.
