通过 GC/MS法对池塘在用含氯消毒剂消毒前后水体中有机物的鉴定比较 ,发现含氯消毒剂在水环境中的主要次生产物为三氯甲烷 ,其生成量与消毒剂的用量、作用时间、反应温度、p H及光照等有关。这种次生产物具有一定的致突变活性 ,因此在养殖生产中必须严格控制消毒的使用量和使用条件 ,尽可能消除其不利影响 By GC / MS method for the determination of organic compounds in ponds before and after disinfection with chlorinated disinfectants, it was found that the main secondary products of chlorinated disinfectants in water environment were chloroform, the amount of which and the amount of disinfectant, Role of time, reaction temperature, p H and light and so on. This secondary product has a certain mutagenic activity, so the production of aquaculture must strictly control the use of disinfection and the use of conditions, as far as possible to eliminate its adverse effects
