| Abstract: |
| To understand the pollution characteristics and ecological risks of pesticides and veterinary drugs in aquaculture environment and non-drugs fishery inputs, the residues of pesticides and veterinary drugs in aquaculture water, sediment, and non-drugs fishery inputs in Shanghai were analyzed using ultra-high pressure liquid chromatography electrostatic field orbital ion trap mass spectrometry. The risk quotient(RQ)method was used to evaluate the ecological risk of the screening results. The results showed that a total of 13 drugs were screened from 180 samples(27 waters, 43 sediments, and 110 inputs)from 27 farms; they include nine veterinary drugs(amantadine, diazepam, enrofloxacin, florfenicol, gatifloxacin, trimethoprim, avermectin B1a, erythromycin, and pefloxacin)and four types of pesticides (carbendazim, prometrazine, simetryne, and ethoxyquin)were included. Nine types of 70 drugs were screened from the water, six types of 93 drugs were screened from the sediment, and seven types of 37 drugs were screened from the input. Carbendazim, enrofloxacin, and trimethoprim were all present in the three types of samples. The range of the concentration of drugs screened from water, sediment, and non-drugs fishery inputs was 6.00×10-3~1.88, 1.47~292 μg·kg-1, and 9.68~1.39×105 μg·kg-1, respectively. The results of risk quotient evaluation showed that pesticides and veterinary drugs in the water and sediment samples of aquaculture farms have a certain degree of medium and high risk. Among them, prometrazine in the water had the highest ecological risk, with an RQ value of 3.14, and erythromycin in the sediment had the highest ecological risk, with an RQ value of 2.22. The RQ values of the two drugs exceed 1, indicating high risk. These results suggest that the supervision and control of the whole chain of pesticides and veterinary drugs, especially from non-drugs fishery inputs, need to be strengthened to protect the health of aquaculture ecosystem. |
