• To study the effects of low level manganese (Mn) exposure on the serum neuroendocrine hormones levels of the welders. The exposure group consisted of 41 male welders, 40 male workers without exposing to harmful agents served as controls. The serum contents of prolactin (PRL), luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (TST) and thyroid stimulating hormone (TSH) of 81 subjects were detected by chemiluminescence immunoassay. The geometric mean value of airborne Mn concentrations was 0.03 mg/m(3) (0.003 - 0.519 mg/m(3)) in the welding circumstances. The levels of Mn in red blood cells (RBCs) and urinary Mn of the exposure group were significantly higher than those of control group (P < 0.01). The contents of serum LH and TSH of the exposure group were 2.89 ± 0.69 mIU/ml and 1.45 ± 0.56 uIU/ml, which were significantly lower than those (3.82 ± 1.61 mIU/ml and 2.19 ± 1.28 µIU/ml) of control group (P < 0.01). The serum contents of LH, FSH and TSH of the group exposed to Mn for < 5 ye
