Abstract

|
|
|
Total 11 samples of sediments from the Geum river and the Nakdong river and its estuaries were analyzed to investigate the distribution characteristics of PBDEs and HBCD. Concentration of PBDEs in sediments ranged from 2.19~101.34 (average 30.70, median 20.91) ng/g-dw. The concentration range of PBDEs in river sediments is greater than those of estuary sediments. The HBCD concentration was ranged from N.D.~7.85 (average 1.47, median 0.32) ng/g-dw. HBCD concentrations compared with PBDEs are approximately 1/20 level, which is associated with low domestic usage. Isomer patterns of PBDEs and HBCD suggested that not only the use of commercial products, but the physicochemical properties of these materials, environmental degradation, and environmental behavior could affect the distribution characteristics of these chemicals and their isomers.
