HEMATOLOGIC STUDIES OF HUMANS EXPOSED TO SULPHUR DIOXIDE

The detrimental effects of air pollution on health have been recognized for most of the last years. The outdoor environment in industrial country without strong effective legislation remains a major health hazard. This papers discusses the effect sulphur dioxide in hematologic parameters of humans. The study investigates venus blood samples of 106 habitant of two areas in Albania, an industrial region where the observed ambient air included sulphur dioxide, and the other a non polluted one. The factors that can be effective as risk of hematological problems among habitants have been listed and regarding that, a database is taken.The parameters of blood samples of two areas are compared using ANOVA method and as result, no statistically significant changes are seen in erythrocytes or immunologic parameters examined and in leukocyte. The mean of erythrocytes is at minimum normal value. All parameters of leukocytes formula are examined and using statistical methods is studied the role of independent variables on these parameters. A possibly significant decrease is found in monocytes of rezidents that have only 20 years of timestay, but this is recovered after 40 years timestay. A decrease effect (statistically significant) was noted in lymphocyte.
