摘要
利用GC-MS技术定性和定量分析2008年不同季度太湖梅梁湾水体中的半挥发性有机污染物(SVOCs),并采用多介质环境目标值(MEG)分别就人体健康影响度(ASI)和生态环境影响度(ASII)对太湖梅梁湾水质进行了评价.结果表明,2008年春、夏、秋、冬太湖梅梁湾水体中25种EPA优先控制SVOCs的总浓度分别为17.459,11.140,11.147,5.675μg/L,其中检出率较高的是邻苯二甲酸酯类物质、苯系物和PAHs;健康和生态影响度均小于1,表明对健康和生态尚属安全.
The semi-volatile organic compounds in Meiliang Bay of Taihu Lake in different seasons in 2008 were determined qualitativelical and quantitatively by gas chromatography method with mass spectrometric detection. Ambient severity due to exposure to these organic pollutants were evaluated with the multimedia environmental goals （MEG）, including both health and ecological ambient severity. Total contents of 25 kinds of organic pollutants from water samples in 4 seasons were 17.459, 11.140, 11.147 and 5.675μg/L, respectively. And phthalate esters, benzenes and polycyclic aromatic hydrocarbons had been determined as high detective rate. The total ambient severity （TAS） of both health and ecology were less than 1, which indicated that water in Meiliang Bay was still safe to health and ecology.
