Organochlorine pesticide residues in 12 freshwater Egyptian fish species with special emphasis on Aguilla vulgaris and Mugil cephalus.
Determination of DDT and endrin concentrations was carried out in fishes of Nozha hydrodrome to elucidate reasons for variations in the values, since little seems to be known about pesticide residues in Egyptian freshwater fishes. This study documents and examines the accumulation and biotransformation of water-borne pesticides by the gills, liver, gonads, muscle and heart of fishes tested. The response of eel and mullet to concentrations of 0.05, 0.1, 0.5 and 1.0 ppb DDT and endrin varied among organs, the residues were highest in the liver, intermediate in the gonads and low to non-detectable in muscles and heart for both species.
