Chronic exposure to mercury vapor occurs in the workplace. The classic triad of symptoms involves the oral cavity (gingivitis, salivation, stomatitis), tremor, and psychological changes. Central nervous system symptoms observed in workers exposed to mercury vapor are termed erethism, which includes insomnia, loss of appetite, pathological shyness, emotional lability, irritability, and memory loss. Renal dysfunction as determined by urinalysis has been observed in workers exposed to mercury vapor. Both glomerular (proteinuria) and tubular (enhanced excretion of tubular enzymes) effects have been reported.
