Effect of pesticides on Mediterranean fish muscle enzymes

Abstract

       The effect of the pesticides aldrin, dimethoate and permethrin on muscle pyruvate kinase, lactate dehydro­genase, malate dehydrogenase, succinate dehydrogenase and cytochrome oxidase was investigated in the Medite­ranean fish, Boops boops, Coryphaena hippurus and Mugil cephalus. Aldrin and permethrin stimulated the extramitochondrial enzymes studied. Whilst permethrin inhibited the mitochondrial enzymes, aldrin inhibited only cyto­chrome oxidase. Dimethoate did not affect the extramitochondrial enzymes but inhibited the mitochondrial ones.
