The existence and distribution of certain pesticide residues and metals in the muscles and vescera of Bagrus bayad fish collected from the three main public markets locates at Kalubia governorate, Egypt during the four seasons of the year 2000–2001 were determined. Data indicated that the number of detected pesticides were varied from muscles to vescera, season to season and from location to the other. A different trend was recorded between muscles and vescera contamination. It seemed difficult to interpretate clear trend/pattern of pesticides residues in both muscles and/or vescera of fish samples in relation to season and location factors. In general, the detected amounts of pesticides were below the maximum residue limits with few exceptions. The obtained results indicate the existence of some metals in the muscles of the collected fish samples. The detected elements were Mn, Cu, Pb, Ni and Co. Both of Co and Pb were only detected in the samples collected at autumn, whereas the other metals were detected in all the other seasons and/or locations. Manganese was found in the highest amounts in the analyzed fish samples.
