초록
The accumulation levels of tetrabromobisphenol-A (TBBPA) were investigated in samples of crucian carp and also in samples of associated sediments. Samples were collected from 15 locations along the four major rivers; the Nakdong, Han, Seomjin, and Yeongsan River. TBBPA was detected above the method detection limit from all of the sampling sites both in samples of sediment and muscle tissue of crucian carp. The TBBPA levels ranged from 0.13 to 1.4 ng/g lipid weight in the crucian carp muscle tissue samples, and from 0.090 to 1.1 ng/g dry weight in the associated sediment samples. These levels were much lower than those detected from the sites in adjacent to the point source of TBBPA or around the highly industrialized area. The accumulation levels of TBBPA distributed relatively homogeneously with very low levels, and did not show any increasing trends from the upstream sections to the downstream sections of each river. This result suggests that there may be no point sources of TBBPA along the major rivers investigated in this study
Abstract
The accumulation levels of tetrabromobisphenol-A (TBBPA) were investigated in samples of crucian carp and also in samples of associated sediments. Samples were collected from 15 locations along the four major rivers; the Nakdong, Han, Seomjin, and Yeongsan River. TBBPA was detected above the method detection limit from all of the sampling sites both in samples of sediment and muscle tissue of crucian carp. The TBBPA levels ranged from 0.13 to 1.4 ng/g lipid weight in the crucian carp muscle tissue samples, and from 0.090 to 1.1 ng/g dry weight in the associated sediment samples. These levels were much lower than those detected from the sites in adjacent to the point source of TBBPA or around the highly industrialized area. The accumulation levels of TBBPA distributed relatively homogeneously with very low levels, and did not show any increasing trends from the upstream sections to the downstream sections of each river. This result suggests that there may be no point sources of TBBPA along the major rivers investigated in this study
