Abstract

Eight chlorobenzenes (out of a total of 12 in the congener series) were measured in the sediments from 21 stations in the southeastern coastal areas of Korea. The levels of total chlorobenzene isomers varied between 2.08 and 12.45 ng/g dry weight. The highest contents of total chlorobenzenes (CBs) were found in the sediments from Pohang coast. Trichloro­benzenes (the sum of 1,3,5-, 1,2,4- and 1,2,3-trichlorobenzene) were dominant classes among four congeners, whereas tetrachlorobenzenes (the sum of 1,2,3,5-, 1,2,4,5- and 1,2,3,4-tetra­chlorobenzene) and pentachlorobenzene were low levels. The contributions of total CBs showed similar patterns for all stations with positive significant correlation within CBs species. It means that CBs contamination in the southeastern coasts of Korea came from the similar source.
