岷江成都段有机物污染调查

对岷江成都段有机物污染进行了调查。共设置7个监测断面，共定性检出431种有机物：经过筛选确定苯系物、多环芳烃、有机氯农药、多氯联苯和挥发性卤代烃为主要污染物。对这5类有机污染物定量分析，并对其时空分布及其成因进行了探讨。指出，随着工业的发展，有机物污染问题日益突出，有机化合物的数目增加的很快，我国目前对有毒有害化合物的评价标准远远满足不了需要。建议在严格控制现有有毒有害化合物的基础上制定出更多的评价标准。

Organic Pollutbon Investigation ofthe M injiang River in Chengdu

To investigate the organic pollution of the Mingjiang River in Chengdu. There are seven monitoring sites, and 431 kinds of organic material. The main pollutants are benzene serial materials, polycyclic aromatic hydrocarion, organochlorine insecticide, PCB and volatile halogenated hydrocarbon. These five kinds of organic pollutants were determined, and their distribution was discussed. With the increase of organic pollutants, it need stipulate more evaluation standard for hazard material.
