近年来,由于我国工农业迅速发展,污水处理设施跟不上,致使渔业水域生态环境遭到不同程度的污染和破坏。全国各地渔业污染事故不断发生,给渔业生产带来极大损失。在处理渔业污染事故过程中,鱼类死亡原因的鉴定是一项重要环节,死鱼原因的诊断是十分复杂的问题,除污染中毒死鱼外,病害、缺氧、毒藻、机械损伤等都可能造成死鱼。而化学污染中毒死鱼又包括农药中毒、重金属中毒、非金属无机物或有机物中毒等。因此,分析和探讨化学污染物引起鱼类急性中毒的特征及诊断方法,显得尤为重要。
In recent years, due to the rapid development of industry and agriculture in our country, sewage treatment facilities can not keep up. As a result, the ecological environment in fishery waters has been polluted and destroyed in varying degrees. Fishery pollution accidents all over the country continue to occur, which has brought great losses to fishery production. The identification of the causes of death of fish is an important link in the process of handling fishery pollution accidents. The diagnosis of the causes of dead fish is a very complicated issue. In addition to all the poisoned dead fish, diseases, hypoxia, poisonous algae, mechanical damage, etc. May cause dead fish. The chemical contamination of dead fish and pesticide poisoning, including heavy metal poisoning, non-metallic inorganic or organic poisoning. Therefore, it is particularly important to analyze and explore the characteristics and diagnostic methods of chemical contaminants caused by acute fish poisoning.
