The study determined the levels of cadmium, lead and total petroleum hydrocarbons (TPH) in shrimp waste meal supplemented feeds and droppings of the broiler birds. The samples were collected randomly over a period of two months. Cadmium and lead were determined by atomic absorption spectrophotometry, while total petroleum hydrocarbons (TPH) were determined gravimetrically by following standard methods. The results show for cadmium 0.61 plus minus 0.48 mug/g and 0.81 plus minus 0.32 mug/g, respectively; 9.49 plus minus 2.24 mug/g and 11.49 plus minus 1.55 mug/g for lead; 369.00 plus minus 108.40 mug/g and 330.20 plus minus 59.03 mug/g for TPH, respectively for the starter and finisher feeds. The statistical analysis of variance reveal significant differences at 95% confidence level for lead and TPH compared with control samples. The droppings of the broilers were also collected and analyzed with statistically significant difference existing for lead.
