我国现在的淡水水域养殖通常是在池塘中进行，而池塘中的水是由外界的供水系统提供，很多农村地区的供水系统都比较落后，通常是露天的水渠形式。由于现在农业中使用的农药种类和数量在日益上升，这就会由一些农药残留在露天的水渠中，如果受农药污染水流到养殖的池塘，经过长时间的累积，高浓度的农药残留会给池塘的水产品造成危害，轻者影响水产品的产量，重者会引起水产品死亡，或者高浓度农药残留的水产品流向市场，危害消费者的身体健康，也可能引起食物中毒。因此，对于池塘的水质监测迫在眉睫。The current freshwater aquaculture in our country is usually carried out in ponds, and the water in the ponds is provided by external water supply systems. The water supply systems in many rural areas are relatively backward, usually in the form of open-air canals. As the types and quantities of pesticides used in agriculture are increasing day by day, some pesticide residues will be left in the open water channels. If the pesticide-contaminated water flows into the ponds for cultivation, after a long period of accumulation, the high-concentration pesticide residues will give Aquatic products in ponds cause harm. In mild cases, the output of aquatic products will be affected, and in severe cases, aquatic products will die, or aquatic products with high concentrations of pesticide residues will flow to the market, endangering the health of consumers, and may also cause food poisoning. Therefore, it is imminent to monitor the water quality of ponds.
