POLLUTION BY PCDDS AND PCDFS IN SEDIMENT FROM FRESHWATER FISH CULTURE PONDS NEAR INCINERATION SITES FOR METAL RECLAMATION IN WAN-LI, TAIWAN, REPUBLIC OF CHINA

摘要

Sediment samples from nine culture ponds for freshwater fish at and near waste incineration sites for metal reclamation in Wan-Li, southern Taiwan, Republic of China were analyzed for PCDDs and PCDFs by HRGC-HRMS. Four of nine samples were heavily polluted by PCDDs and PCDFs, indicating the latter to be dominant. The total TEQ concentrations of PCDDs and PCDFs in the four samples were in the range of 257 to 12200 pg/g dry weight. In addition, the levels corresponded to those of surface soil samples from the same waste combustion areas.
