| 摘 要： | 灭多威属高毒农药,其可经地表淋溶等途径污染养殖水体。为了研究雍菜对水体中灭多威及其他水质指标的净化效能以及对罗非鱼生长的影响,以灭多威、罗非鱼、雍菜和室内养殖系统为试材,根据《水和废水监测分析方法》中的方法测得水质指标数据,以液相色谱-质谱联用仪(LC-MS)测得水体中灭多威浓度,以试剂盒测定谷胱甘肽(GSH)含量（DTNB法）、超氧化物歧化酶(SOD)活性（WST-1法）、过氧化氢酶(CAT)活性（紫外法）。研究结果表明,罗非鱼的生长速度随着水体中灭多威浓度的上升而降低。受灭多威污染可致罗非鱼肝脏氧化压力增大,SOD、CAT和GSH的活性发生变化。雍菜可通过机体吸收有效降低养殖水体中灭多威的含量,对受灭多威污染水体中TN、NH4 +-N、NO3 --N、NO2 --N等具一定的净化作用,并可减轻罗非鱼肝脏的氧化应激。研究显示,水体种植雍菜可有效减轻灭多威对水体的污染,保证鱼类的生长。

| Abstract: | Methomyl is a highly toxic pesticide, which can contaminate aquaculture water by means of surface leaching. To study the purification efficiency of water spinach on methomyl in the water body and other water quality indexes and investigate the impact of water spinach on tilapia, we took methomyl, tilapia, water spinach and indoor cultivation system as test materials to measure the water quality indexes according to the Water and Wastewater Monitoring Analysis Methods. The methomyl concentration in the water body was measured by the Liquid Chromatograph Mass Spectrometer (LC-MS), and the glutathione (GSH) content (the DTNB method), superoxide dismutase (SOD) content (WST- 1 method) and catalase (CAT) content (the Ultraviolet Spectroscopy) were measured using the assay kit. The results showed that the growth rate of tilapia decreased with the increase of methomyl concentration in water. Methomyl contamination led to increasing the oxidative pressure of the tilapia liver, and caused the changes of SOD, CAT and GSH. Water spinach could effectively reduce the content of methomyl in the aquaculture water through body absorption, it purified TN, NH4 +- N, NO3--N and NO2--N in the water contaminated by methomyl to a certain extent and reduced the oxidative stress of the tilapia liver. The study reveals that water spinach grown in water can effectively reduce the pollution of methomyl and ensure fish growth. |
