The Effects of Air Pollution and Smoking on Cadmium Concentration in Human Blood and Correlation with Biochemical Parameters

Problem statement: The study described the research of the effects that the environment pollution and smoking have in cadmium concentration in human blood, as well as in the correlation between cadmium and the biochemical parameters. Approach: In a comparative study of cadmium concentration in blood of human population of two different environments in Kosovo, one nearby Kosovo Thermo Power Plants (Obiliq), a highly polluted environments (Investigated Group) and the other that was considered as relatively clean rural environment Dragash (control group). Results: The results showed that there exists a significant difference in the average concentration of cadmium in human blood between the Investigated Group (IG) and the Control Group (CG) (t = -3.34, p = 0.0006). The series of determination of cadmium concentration in blood of population that lives in this environment had shown direct effects in biochemical parameters (direct bilirubine, total bilirubine). Conclusion: Air pollution (from coal burning in power plant) and smoking were very important factors for the level of cadmium concentration in blood, which had an inhibitory effect in the syntheses of bilirubine.
