Determination of zinc serum in the workers of sarcheshme copper complex

Zinc is one of the essential elements in biological system. The role of this element in many enzymes has been proved. Zinc has an antagonistic effect on the toxic elements such as cadmium, as both binds to a carrier protein called metalothionein . Zinc can be found in atmosphere of different industrial environment. Due to its importance, it's concentration in the serum of ۳۹۹ Male workers of sarcheshme copper complex was Investigated. The samples were taken randomly from different sections and the level of zinc were determined by atomic absorption spectrophotometry. The average serum concentration of zinc was ۸۴.۸۷+_۱۹.۹۹ mg/ dl which was significantly lower than that of the Blood bank Donors as the control group ( ۱۳۰.۷+_۳۹.۷). No significant correlation was found between the level  of zinc and age, period of working and  the type of the work in the factory.
