1. Introduction
Organochlorine (OC) pesticides are among the agrochemicals that have been used extensively for long periods. They have been used widely in agriculture, as well as, in mosquito, termite and tsetse fly control programs (Guo et al., 2008). OC pesticides are characterized by low polarity, low aqueous solubility and high lipid solubility (lipophilicity) and as a result they have a potential for bioaccumulation in the food chain posing a great threat to human health and the environment globally (Afful et al., 2010). Residues and metabolites of many OC pesticides are very stable, with long half lives in the environment (El-Mekkawi et al., 2009). Studies have shown that DDT is still in its highest concentration in biota of some areas. It is a hydrophobic molecule which disrupts ionic channels like Na+/K+ pumps in nervous cell membrane leading to automatic stimulation of neurons and involuntary contraction of muscles (Esmaili Sari, 2002). Many other recent works have indicated the presence of OC residues in surface waters, sediments, biota and vegetations (Darko et al., 2008; Dem et al., 2007; Wang et al., 2007; Imo et al., 2007; Ize-Iyamu et al., 2007). The persistent nature of organochlorine residues in the environment may pose the problem of chronic toxicity to animals and humans via air, water and food intake. Many of these OC pesticides and their metabolites have been implicated in a wide range of adverse human and environmental effects including reproduction and birth defects (Edwards, 1987), immune system dysfunction, endocrine disruptions and cancer (Adeyemi et al., 2008). Fish are used extensively for environmental monitoring (Lanfranchi et al., 2006), because they uptake contaminants directly from water and diet. Generally the ability of fish to metabolize organochlorines is moderate; therefore,
