Abstract/OtherAbstract:
Tetrabromobisphenol A (TBBPA) is the most widely used brominated flame retardants (BFRs). It has been detected in various environment media and has been approved to be high toxic to aquatic organisms. However, the exposure levels of TBBPA in the main watersheds in China have not been investigated sufficiently. In this study TBBPA concentrations in water, sediment and tissues of four fish species from Lake Chaohu were determined. Spatial and temporal distribution patterns of TBBPA in water and sediment, and the relationship among TBBPA concentrations in fish tissues and fish size were analyzed. The results showed that the maximum TBBPA concentration in sediment was 518 ng/g in March 2008. It is almost the highest value than those ever reported anywhere in the world. In lake water, TBBPA level reached the maximum value of 4.87 μg/L in July. Tissue distributions of TBBPA in four fish species were similar, and the mean concentrations in the fish were in the range of 28.5-39.4 ng/g, much higher than those reported in Japan, Europe, and the United States. The maximum concentrations of TBBPA were found in kidneys where TBBPA concentration was positively correlated with fish size of Cyprinus carpio. Results demonstrated a widespread distribution of TBBPA in Lake Chaohu. The source was mainly inflow rivers near the cities. The distribution coefficient among water, fish, and sediment was 1:28:117. This indicated that sediment was the main repository for TBBPA within Lake Chaohu. Furthermore, TBBPA may pose a potential ecological risk in the lake during summer.
