| 摘 要： | 采用5点法对珠江广州河段白鹅潭水域进行垂线采样,并采取表层沉积物的界面水。水样采用GF/F玻璃滤膜过滤分离出颗粒相和溶解相,据美国EPA标准对有机氯农药进行定量分析,结果显示有机氯农药浓度范围是23.89~61.69ng/L;据有机氯农药浓度的垂向分布特征、颗粒相为主要输运方式的DDTs的中下层高浓度跃层的形成、以及有机氯农药在颗粒相和溶解相浓度分布和分配系数表明,水柱上层和下层水体的有机氯农药的输入方式有较大的差异,结合主成分分析结果,在流速增加的动力条件下,表层沉积物存在二次污染的风险。

| Abstract: | Six water samples in different depths in water column from Guangzhou channel of Humen estuary in the Pearl(Zhujiang) River were collected,and were filtered by GF/F glass fiber filter.Organochlorine pesticides(OCPs) in particulate and dissolved phase were identified and measured based on USEPA 8000 series methods and under quality assurance and quality control(QA/QC).Concentrations of OCPs varied from 23.89 to 61.69 ng/L.The vertical distribution of OCPs,the partition coefficients(Log Kp) of OCPs between par... |
