title: A review of human exposure to polybrominated diphenyl ethers (PBDEs) in China.
abstract: This paper reviews recent studies on human exposure to polybrominated diphenyl ethers (PBDEs) in China, with particular focus on external exposure routes (e.g. diet and dust ingestion, inhalation of air) and internal doses based on biomonitoring studies of PBDEs (e.g. breast milk, blood and hair). PBDE concentrations reported for fish samples collected from electronic waste (e-waste) recycling sites, PBDE manufacturing sites, local markets in selected cities and estuarine areas in China have been compiled. House dust has been a significant contributor to human exposure to PBDEs in many countries. This is especially true for toddlers, who are exposed to significantly higher doses of PBDEs than adults. Infants are also exposed to high levels of PBDEs via breast-feeding. The general population's inhalation exposure to PBDEs from household products is likely a less significant source into the indoor environment. In addition, the contribution of several exposure pathways to PBDEs among various age groups was analyzed. We found that house dust contributed most to the daily exposure to PBDEs for both toddlers and adults in urban areas of China. Furthermore, workers and residents in and around electronic recycling and PBDE manufacturing sites are exposed to the highest PBDE levels among all populations studied thus far. For the occupationally exposed populations, BDE209 was the dominant congener, in most cases. Rigorous pollution prevention and occupational protection measures are needed in China to mitigate potential health effects associated with PBDE exposures.
