美国黑石河有机污染物输送入海的一维水质模式研究

DEVELOPMENT OF ONE DIMENSIONAL WATER QUALITY MODEL FOR ORGANIC POLLUTANTS TRANSPORTED TO SEA FROM THE BLACK-STONE RIVER

沿着黑石河沿岸城镇和废物处理场设九个取样站,于1985年夏秋取样三次。在分析和统计的基础上提出黑石河有机污染物一维水质模式,指出黑石河有机污染物的来源、输送和归宿。

This article introduces the study on development of one dimensional water quality model for the organic pollutants transported to Narragansett Bay from Blackstone River, Rhode Island, U. S. A. Samples were taken three times at nine stations along the Blackstone River in Summer and Autumn of 1985. A one dimensional water Quality model for the sources, transport and fate of organic pollutants was developed from their chemical analyses and statistics.The results of this model show that suspended particle, PAHs, PCBs did not sink to the bottom of the River during the transport, but the total hydrocarbons, phthalates and cho-prestnol have sunken to the bottom and their sunken percentage were 47%, 65% and 75% respectively. The HCH could not be discussed here.
