Seventy four male workers in the Idrija mercury (7439976) operations were examined and the blood and urinary mercury levels determined. The ranges and averages of those with and those without clinical evidence of mercury poisoning did not demonstrate any remarkable difference. Three symptomatic subjects with a prior history of mercury poisoning had low levels of mercury. One case of optic neuritis was seen. It is impossible to determine if this was due to inorganic and metallic mercury. Seventeen workers in a mercury mine in the Philippines with mild symptoms of poisoning and air exposure similar to that at Idrija showed blood and urine mercury content analogous to that found in the Idrija workers. Two years later a second study was done at the Philippines mine encompassing 30 workers. A comparison of workers at the smelter area achieved higher blood and urine mercury levels than found in the earlier study, reflecting the higher mercury vapor concentration in air, but this does not appear to be related to production of symptoms of poisoning. No increase in symptoms of mercurialism was found.
