Immunological profiles in workers occupationally exposed to inorganic mercury.
Forty-one male mercury-exposed workers were examined for the serum concentration levels of immunoglobulins (IgG, IgA, IgM), alpha-1-antitrypsin (A1AT), alpha-2-macroglobulin (A2M), ceruloplasmin (CPL) and orosomucoid (ORO). In the period preceding this investigation the mercury concentrations in workplace air ranged from 0.106 to 0.783 mg.m-3, the range of urinary mercury concentrations was from 0.029 to 0.545 mg.1(-1). All but two (IgG and A1AT) of the immune parameters tested were at the levels that were evidently higher than those found in a control group of 55 workers matched by age who lived in a relatively clean area. The percentage of individuals with no value out of the range of normal physiological limits was in the controls almost 80%, in the exposed 36.6% only. These findings confirm the literature data which show that an inhalation exposure to inorganic mercury may evidently have a stimulating effect on some serum proteins in humans.
