[Clinical-toxicological aspects of micro mercury poisoning]

Thirty workers were hospitalised after clinical and laboratory screening of 65 women and 35 men from electrical lamp factory. The mercury concentration in air of the working places varied from normal value (0.01 mg/m3) to 0.04-0.05 mg/m3. Target neurological anamnesis, internal and neurological examination, EEG, renal function tests and several laboratory parameters of large extent were carried out. The analysis of results establishes the signs of micromercurialism in 20% of the examinees. The authors determine the peculiar clinical (neurasthenic syndrome, periodontal diseases ) and biochemical (blood Hg level and urinary mercury) parameters of this early, functional stage of the chronic Hg poisoning.
