In process of chlorine-alkali electrolyze the big mercury failure exist in vapor shape, which across respiratory system, expire in exposed persons organism. The aim of the work was to examine connection between mercury vapor air pollution and sicknesses coming from diseases belonging to the XI group of diseases by International Classification of Diseases th (ICD) - 10 revision. Exploring groups were workers “Kalium chemistry” factory and administration at CI ”Zupa”. Recognized diagnosis on periodical exams year 2000, 2002 and 2004 were entered in reports (expertises) analyzed later on. Analyzed reports for total 571 examinees were done, 184 examinees year 2000, 191 examinees year 2002 and 196 year 2004. As of diagnosis recognized the diagnoses were separate for diseases belonging to XI ICD group. Examinees were divided in a four group according to the grade of exposure: I group day by day exposed; II group sporadically exposed; III group earlier
exposed; IV group not exposed. First, second and third group of examinees were workers of “Kalium chemistry” factory. It was established during the examination at rooms were exposed workers stay that only mercury vapor pollution 3.01 overcomes Maximum Permitted Concentration allowed by JUS. The frequency differences testing between groups according to the grade of exposure, like as frequency differences testing of sicknesses between all exposed opposite un-exposed, showed
to us that differences are statistically significant. Based on the results of the this research it can be conclude that connection exist between mercury vapor air pollution and sicknesses coming from diseases belonging to the XI group of diseases by ICD.
