The role of metals exposure in allergic diseases in workers who work in iron factories

Essential metal concentrations in the blood are an important measure for monitoring environmental and workplace exposure to metals. The determination of this training. To conclude the range of zinc (Zn), lead (Pb), copper (Cu) and manganese (Mn) in the blood of 50 men working in factories doors and windows etc. For long period with 20 healthy men as controls not working in this occupation. The study found an increase in the toxicity rates of the aforementioned metallic substances and that this increase is more in the ages from 30 to 50 years. The study also found an increase in the toxicity of metallic substances It leads to a higher rate of IgE caused by infection with these agents and some allergic diseases, including skin allergies (atopic dermatitis) and asthma, or both cases, where the rate of IgE increases and is higher in mixed people infection. The conclusions of the study that prolonged exposure to metallic substances leads to toxic effects, which in turn leads to the emergence of some allergic disease
