Correlative studies on changes in lipid composition of gills and uptake of chemicals of willow shiner fish (Gnathopogon caerulescens) by exposure to detergent.
One group of willow shiner (Gnathopogon caerulescens) was exposed to 0.1 mg/l dodecylbenzenesulfonate (DBS) for analysis of lipid composition of gill extracts. Another group of fish was exposed to 0.0003 mg/l 2,4,6-trichlorophenyl-4'-nitrophenyl-ether (CNP) after regular intervals of pre-exposure to 0.1 mg/l DBS for analysis of uptake of CNP. The whole body residues of CNP were characterized by a 60% drop in DBS pre-exposure for 14 and 21 days. The cholesterol/total phospholipid ratio increased to 0.22 and 0.28 after 14 and 21 days from the normal of 0.18. These biochemical results might be correlated with the changes observed by the uptake of CNP.
