Abstract

Abstract

The BHC and DDT contents in three species of Nemipterus fish from continental shelf of northern South China Sea were determined by GC-ECD method in order on explore the effect of BHC and DDT on fishery resources and quality of fishery products off shore.The data showed that the contents of BHC and DDT in the fish muscle were from 0.04 to 0.89 with mean of 0.26μg/kg (wet mass), and from 0.71 to 8.0 (3.1)μg/kg (wet mass), respectively, both were below the superior limits in fishery products published by home and abroad, and under the mean level of some marine fish from near shore in Asia and Pacific Ocean.The mean content of BHC or DDT in the fish muscle along Guangdong was higher than that of Taiwan Bank.No significant difference of mean content of BHC or DDT in the fish muscle were observed among the different species or between the near shore and off shore (P > 0.10).In the fish N.bathybius, pesticide contents were significantly higher in the liver and lower in the gill thread (P < 0.05).The tissue of N.bathybius containing pesticides from high to low was in the order of liver greater than abdomen muscle greater than back muscle greater than intestines greater than skin greater than gill thread for BHC, and liver greater than abdomen muscle greater than back muscle greater than skin≈intestines greater than gill thread for DDT.The content of pp-DDT, op-DDT positively related to lipid content in different tissues of N.bathybius (P < 0.05).
