Concentrations of chlorobenzenes, hexachlorobutadiene and heavy metals in surficial sediments of Kaohsiung coast, Taiwan

This work analyzes surface sediment samples collected from 40 stations along the Kaohsiung coast in southern Taiwan for chlorobenzenes (CBs), hexachlorobutadiene (HCBD) and heavy metals (Cu, Zn, Pb, Cd, Ni, Fe, Mn and Cr). The highest CBs concentrations are recorded in station T7-15 (about 10 km wes...

Description
Summary:This work analyzes surface sediment samples collected from 40 stations along the Kaohsiung coast in southern Taiwan for chlorobenzenes (CBs), hexachlorobutadiene (HCBD) and heavy metals (Cu, Zn, Pb, Cd, Ni, Fe, Mn and Cr). The highest CBs concentrations are recorded in station T7-15 (about 10 km west off the outlet of Da-lin-pu ocean outfall pipe), with total di-, tri-, tetra-, penta- and hexa-chlorobenzenes concentrations of 290.5, 117.1, 64.5, 15.7 and 22.3 ng/g, respectively. The major pollution source of HCBD is most likely located in the Tso-yin ocean outfall field; while the Dah-lin-pu ocean outfall field and Kao-ping Chi estuary, located in the southern portion of Kaohsiung coast, are the major contributors of hexachlorobenzene. The concentration of CBs congeners correlate faily well with each other, as do metals. However, concentrations of organics (CBs and HCBD) did not correlate with metals. This finding implies that the pollution characteristics of organics and heavy metals in this highly utilized coastal zone markedly differ from each other.
