ملخص: ResumeLe dosage du mercure total sanguin a ete effectue chez trois groupes de sujets travaillant dans un complexe d'extraction du mercure a partir de son minerai, le cinabre (sulfure mercurique). Les dosages sont realises par spectrophotometrie d'absorption atomique Le dosage sanguin est egalement realise chez un groupe de 18 temoins, non professionnellement exposes, incluant 11 sujets porteurs d'amalgames dentaires. La technique ne detecte pas de mercure chez quatorze sujets du groupe. En revanche, 4 autres sujets, tous porteurs d'amalgames dentaires, presentent des taux sanguins significatifs (3,5 a 20 [mu]g Hg/L). Il est a noter que les taux les plus eleves, retrouves chez 3 sujets (14, 15 et 20 mg Hg/L), correspondent au port de 2 et 3 amalgames depuis 4 et 6 annees.SummaryMercury was determined in blood of three groups of subjects working in a mercury extraction complex starting from cinnabar (HgS). Mercury was carried out by cold vapor atomic absorption spectrometry on digested samples. The first group of 26 subjects, working directly with the extraction of mercury, is very exposed with an average concentration of 53,9 [mu]g Hg/L (recommended value should not exceed 15 mg Hg/L). The second group, in charge of the security of the site, is fairly exposed (15,4 [mu]g Hg/L: n = 31). As for the third group of 32 workers, employed in the services of maintenance and logistics, shows an average level of 4,2 [mu]g Hg/l reflecting a weak exposure. The differences between the average levels were very significant (p [mu]g Hg/L). It should be note that these levels, correspond to 3 persons with 2 and 3 amalgam fillings since 4 and 6 years.
