Sources and distribution of chlorobenzenes and hexachlorobutadiene in surficial sediments along the coast of southwestern Taiwan

摘要

the spatial distribution of chlorobenzenes in surficial sediments of the estuaries of major rivers along the coast of southwestern Taiwan was determined. Analytical results from sediment sampling stations indicate that the three outfall fields near Taiwan's largest industrial city, Kaohisung, exhibit the highest concentrations of cchlorobenzenes. More specifically, sediments from Tso-yin outfall field, which receives the wastewater from a very large petrochemical complex, had concenration of 1,3,5- trichlorobenzene, pentachlorobenzene, heachlorobenzene and hexachlorobutadiene 2-3 times higher than those from Chon-chou and Da-lin-pu outfall fields.
