[Mercury burden in humans caused by housing in formerly mirrored rooms].

42 persons aged from 3 to 70 years, who have lived in rooms with mercury pollution (mercury in the air 1-70 micrograms/m3), were examined clinically and by bio-monitoring (blood and urine). There was no evidence of macro-mercurialism. 2 persons showed reversible clinical signs of mercury intoxication. The correlation between mercury level of the indoor air and blood or urine is presented, the clinical findings and threshold values are discussed.
