Occurrence; distribution and accumulation of pesticides residues in water, sediment and fish parts from a dam in Nigeria were studied. A gas chromatography coupled with electron capture detector (GC-ECD) was used to quantify the pesticides residues after careful extraction and clean-up. Trace amounts of the analysed pesticides were detected in all the sampled matrixes. High level of variations were reportedin the water and sediments values as observed in the calculated CV% but being more pronounced in sediments. In general, pesticides were obviously higher in the head and muscle than liver with a percentage ratio of 36.8: 33.7:29.5 respectively. Triadimefon, heptachlor, aldrin, chlordane and prochloraz showed evidence of high accumulation in the fish parts.
