珠江入海口水体中多溴联苯醚及其来源分析
Distribution and source of polybrominated diphenyl ethers (PBDEs) in riverine water of the Pearl River Delta
摘要
Abstract
A large-scale sampling program was conducted to collect water samples at eight major riverine nmoff 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.关键词
