The occurrence of Lindane in some Egyptian water and its effects on swimming performance of carp fish cyprinus carpio

ABSTRACT

Residues of lindane were analyzed by capillary gas chromatography in water from different investigated areas. Variations were observed in the levels of lindane with the highest concentration at Rossetta Branch followed by Damietta Branch, Maryut Lake and Idku Lake. The median lethal concentration of lindane after 24 hours and 96 hours were 42 and 25.8 mug/l, respectively. The residues level of lindane from different investigated areas as well as its effects on fish swimming performance have been studied. Lindane was found to affect significantly fish swimming performance. It is suggested that lindane may influence the exchange of respiratory gases or the metabolic pathways involved in the mobilization of energy
