AB  - The objective of this study was to determine the concentrations and possible 
      sources of heavy metals and persistent organic pollutants (POPs) in water and 
      estuarine sediments from Gao-ping River in order to evaluate the environmental 
      quality of aquatic system in southern Taiwan. High concentrations of heavy metals 
      including Cr, Zn, Ni, Cu and As, ranging from 10.7 to 180 mg/kg-dry weight (dw), 
      were detected in sediments from Gao-ping River. When normalized to the principal 
      component analysis (PCA), swinery and electroplating wastewaters were found to be 
      the most important pollution sources for heavy metals. Of various organochlorine 
      pesticide (OCP) residues detected, aldrin and total-hexachlorocyclohexane (HCH) 
      were frequently found in sediments. The total concentrations of OCPs were in the 
      range 0.47-47.4 ng/g-dw. Also, the total-HCH, total-cyclodiene, and 
      total-dichlorodiphenyltrichloroethane (DDT) were in the range 0.37-36.3, 
      0.21-19.0, and 0.44-1.88 ng/g-dw, respectively. The polychlorinated biphenyl 
      (PCB) concentrations in sediments from Gao-ping River ranged between 0.37 and 
      5.89 ng/g-dw. The PCB concentrations are positively correlated to the organic 
      contents of the sediment particles. alpha-HCH was found to be the dominant 
      compound of HCH in the sediments, showing that long-range transport may be the 
      possible source for the contamination of HCH in sediments from Gao-ping River. In 
      summary, trace amounts of POPs in estuarine sediments from Gao-ping River were 
      detected, showing that there still exist a wide variety of POP residues in the 
      river sediments in Taiwan. These POP residues may be mainly from long-range 
      transport and weathered agricultural soils, while heavy metal contamination is 
      primarily from the swinery and industrial wastewaters.
