近江牡蛎作为重金属污染生物指示种的初步研究

对近江牡砺作为监测广东岸海域Ｃｕ，Ｚｎ，Ｃｄ，Ｐｂ污染的生物指示种的可能性进行了初步研究和评价，应用ＰＯＬＹＤＩＶ统计技术对采自广东沿岩海域１４个站点的近江牡盛的重金属含量进行了统计分析，结果表明近江牡蛎受Ｃｕ，Ｚｎ，Ｃｄ污染的地理分布类型与广东沿海排放的工业废水的分布以及潮间带生物和表层沉积物的Ｃｕ，Ｚｎ，Ｃｄ含量分布相一致，因此，近江牡蛎可作为监测研究Ｃｕ，Ｚｎ，Ｃｄ污染的可靠生物指示种，但能

Oyster Ostrea rivularis as an indicator of heavy metals pollution

Preliminary studies have been undertaken to test the indicator ability of the oyster Ostrea rivularis for monitoring copper, zinc, cadimium and lead in seawaters along Guangdong province. Applications of POLYDIV statistical analysis to heavy metal concentrations in oysters from 14 sites along Guangdong coastal waters confirmed that profiles of copper, zinc and cadmium abundance in the oyster agreed substantially with the distribution of industrial discharge along Guangdong province, amd also with patterns of contamination found in organisms and sediments collected from the tidal zone along Guangdong provice. As a result,this oyster appears to be a reliable bio-indicator for monitoring copper, cadimium and zinc,although its use to monitor lead requires further study.
