2014 Abstract: The influence on the future of our country by the application, environmental distribution and ecological risk of Polybrominated diphenyl ethers (PBDEs) is a social issue, particularly concerning about industry, environment, health and human reproduction. Due to their high flame retardant efficiency, excellent thermal stability and low price, PBDEs are widely used as flame retardant additive in many fields including electronics, electrical appliances, chemical industry, transportation, building materials, textile and oil industry. Once PBDEs were discharged into the environment, they can migrate and accumulate in the sediments and organisms, enter human body and harm to human health by endocrine disturbance, liver toxicity, neurotoxicity and fertility falling. Thus, this review focuses on the source, characteristics and environmental impact of PBDEs by analyzing literatures about PBDEs′ production and application, physical and chemical characteristics and toxicity. the environmental background concentrations, distribution, 环境科学学报35 卷migration and time effect of PBDEs from five aspects, i.e. sediments, water, atmospheric, aquatic organisms and human body, were studied and the results indicate that the spread of PBDEs pollutants is a global phenomenon. sediment is a main place for the fate of PBDEs. the indoor concentration of PBDEs is higher than outdoor. The concentration of PBDEs in water is low, and both aquatic organisms and human body can accumulate PBDEs by the intergenerational transmission through the diet, milk i........
