[Assessment of a risk from environmental factors to human health].

Analysis of the findings has shown that the estimation of the sensitization requires the use of a battery of tests, by taking into consideration both the persons having positive tests and the number of positive tests of the used ones. It is necessary to note that the estimation of the specific sensitization to hexavalent chromium has indicated the higher levels of parameters and percent of positive tests among the children living in the area adjacent to the industrial zone with a further decrease as the major sources of pollution is farther. It should be noted that the chromium sensitization is 10% even in the most distant areas.
