Abstract
Abstract The prevalence of lead, cadmium, chromium, nickel, and magnesium in liver and kidney samples of slaughtered cattle at Sokoto abattoir was determined using Atomic Absorption Spectrophotometer. A total of twenty four samples were collected for analyses. Among the samples 19, 21, 23, 16, and 24 were positive for Lead, cadmium, chromium, nickel, and magnesium respectively. The mean concentration of lead, cadmium, chromium, nickel, and magnesium in liver of the slaughtered cattle were 1.523 mg/kg, 2.687 mg/kg, 4.775 mg/kg, 0.938 mg/kg, and 76.167 mg/kg respectively, while the mean concentration of Lead, cadmium, chromium, nickel, and magnesium in kidney of slaughtered cattle were 0.8442 mg/kg, 2.058 mg/kg, , 4.894 mg/kg, 0.772 mg/kg, and 68.258 mg/kg respectively. There was significant difference in the concentration of lead, cadmium, chromium, nickel and magnesium in liver and kidney of slaughtered cattle (P< 0.05). The mean concentration of lead, cadmium, chromium, in both liver and kidney of slaughtered cattle were higher than the permissible limit recommended by Food and Agricultural Organization.
