辽宁省普兰店湾养殖企业扇贝种苗死亡原因

Research on death cause of scallop seedlings in Pulandian bay of Liaoning province

通过对辽宁省普兰店湾养殖企业取水海域的监测和污染源分析,探究该地区2010年1月养殖企业扇贝种苗大量死亡的原因。通过水质监测和污染源调查发现:海水中氰化物和挥发酚显著超标是各水产养殖企业种贝、幼苗死亡的直接原因,而氰化物和挥发酚均属于合成氨工业产生的特征污染物,故以合成氨为主要中间产品的化工企业是此次事件的主要污染源,希望各大型化工企业以此为鉴,严格控制未达标生产废水的排放,维护我国渔业生态环境的健康发展。

Monitoring on marine area of cultivation enterprises and searching for pollution sources in Pulandian bay were taken to find out the death cause of massive scallop seedlings in January of 2010. The investigating results indicate superstandard cyanide and volatile phenols in the seawater of cultiva- tion enterprises cause the fishery accidents. Because cyanide and volatile phenols are the specific pollu- tants of synthetic ammonia industries, chemical industrial enterprises which used synthetic ammonia as intermediate should be the main pollution sources for these fishery accidents. Finally, it is hoped that all the chemical industrial enterprises would learn from the example and control the discharge of wastewater strictly to maintain the healthy development of ecological fishery environment.
