摘要：A general awareness on the safety consumption of food in our society is imperative. In determing the trace element that could be toxic, three different organs (liver, kidney and lung) of cows were carefully selected and analyzed for the quantification of essential trace element, Cr and potentially toxic trace elements, Pb and Co. Atomic Absorption Spectrophotometry (AAS) was used for the analysis. The results showed that the concentrations of these elements were relatively high with highest being recorded in the liver. The concentration has been attributed to the source of food of the animals and other environmental factors.
