Abstract

An E-waste dismantling area in southern China was selected as the exposure area and a green plantation with no E-waste dismantling was chosen as a control area. Sex hormone levels were measured in the serum of 187 males in the exposure area employed in E-waste dismantling, 74 males in the exposure area not employed in E-waste dismantling and 92 males in the green plantation. Information was collected on the ages of study subjects, E-waste dismantling techniques and processes, length of time employed in E-waste dismantling, eating habits and living habits. Serum results from the three treatment groups were analyzed for correlations between the concentration of heavy metals and Follicle stimulating hormone and Luteinizing hormone levels. We found that males with occupational exposure to E-waste have higher levels of Follicle stimulating hormone in their serum than males who do not have occupational exposure to E-waste. The average value of which was 10.94 mLU/mL. The serum Luteinizing hormone levels of the non-occupational exposure group was higher (average value of 5.80 mLU/mL) than serum Luteinizing hormone levels of the green plantation group. The B-Pb ad B-Cd concentrations of occupation group males are similar to the concentrations of non-occupation group males, while they are higher than the B-Pb ad B-Cd concentrations of green plantation group males. A correlation analysis suggests that there are significant correlations between the serum Follicle stimulating hormone levels and B-Cu, B-Pb, B-Cd of occupational group males. The serum Follicle stimulating hormone levels have significant correlations with B-Pb and B-Cd of non-occupational group males. There was no correlation between Luteinizing hormone levels and the heavy metal concentrations of occupation group and non-occupational group males. There were significant correlations between serum Follicle stimulating hormone levels and the pickling dismantling method, consumption of external food and alcohol consumption (P < 0.05). There was no significant correlation between the other confounding factors and serum Follicle stimulating hormone or Luteinizing hormone levels in males employed in E-waste disassembling.
