摘　　要：对珠江三角洲19个重点入河排污口共8个水功能区的污染状况进行研究，在常规项目监测的基础上，采用GC—MS定性分析样品中的有毒有机污染物，并对其中的59种有机物进行定量分析。结果表明，42％的排污口存在超标情况；有机污染物质量浓度范围为3．92～32．5μg/L，且79％的排污口以酞酸酯类为主要有机污染物；除了总有机污染物与TP外，各个污染指标之间的污染负荷比均具有显著相关性，其中总有机污染物、COD和BOD5、NH，-N的回归方程关联度最好。The pollutants from 19 key outlets （including eight water Junction zones） in the Pearl ltlver Delta were studied. Based on general parameters, poisonous organic pollutants were qualitatively analyzed by GC-MS, and 59 of them were quantitatively analyzed. The results show that 42% of the outlets exceeded the standard; the concentration of organic pollutants ranged from 3.92 to 32. 5 μg/L, and 79% of the outlets had the main organic pollutant of phthalate ; significant correlations were found between pollution load ratios of all the parameters, except between the total organic pollutants and total phosphorus; and the highest precision of the regression equation was found between the total organic pollutants and COD, and between BODs and NH3-N.
