Description
Summary:The aim of this research was to determine the heavy metals concentration in blood (Pb, Ni and Cd), serum (Cu and Zn), hair and milk (Pb, Ni, Cd, Cu and Zn) of cattle raised in industrial (with steel mill) and non-industrial areas in Minas Gerais, Brazil. The samples were collected during summer and winter, aiming to verify animals contamination related to environment and year season. The environment significantly influenced the concentration of Cu obtained on serum samples, with higher values for cattle from the industrialized area. The sampling time affected the concentration of Cu (serum), Zn (serum and milk), Pb (blood) and Cd (blood and hair), with higher values for summer, except for Cd measured on hair.
