| 摘 要： | 2005年3月至2006年2月,选取珠江8个入海口,进行每月1次为期1周年的水样采集。检测了96个水样的多溴联苯醚（PBDEs,包括BDE 28、47、66、85、99、100、138、153、154、183、196、197、203、206、207、208和209）的残留状况。水体中PBDEs的质量浓度为0.344～68.0 ng·L-1。PBDEs的组成分析结果表明：珠江水体PBDEs的来源以土壤和沉积物源为主,而目前珠三角陆地环境中PBDEs仍不断蓄积,其通过珠江地表径流迁移转换的PBDEs将逐年增多,给珠三角水生态环境带来的压力逐日增加,所造成的生态环境及公众健康影响将是深远的。

| Abstract: | A large-scale sampling program was conducted to collect water samples at eight major riverine runoff outlets of the Pearl River Delta（PRD） monthly from March 2005 to February 2006.Ninety-six water samples were measured for PBDEs（sum of 17 BDE congeners,i.e.,BDE 28,47,66,85,99,100,138,153,154,183,196,197,203,206,207,208,and 209）,and the PBDEs concentrations were 0.344-68.0 ng·L-1.Results from compositional profiles indicated that soil and sediments are the main sources of PDBDEs in the water body of the Pearl River.Furthermore,the study also found that PBDEs in the terrestrial environment of the Pearl River Delta continued to accumulate,and the yearly input of PBDEs into Pearl River from surface runoff continues to increase,putting more and more stress on the water ecological environment;as a result,the impact of PBDE on the environment and human health is expected to persist for many years to come. |
