Abstract
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.
Highlights
Kosova possesses a considerable energy potential of coal
The purpose of this study is to find the correlation between environmental pollution, smoking and the concentration of cadmium in blood[3], as well as the correlation between cadmium and Total Bilirubine (TB) and Direct Bilirubine (DB) in the blood of human population
We have investigated 75 human blood samples: 50 blood samples of the citizens from the industrial area of Obiliq, who in this project are treated as the Investigated Group (IG) and 25 blood samples of the citizens from the Municipality of Dragash, who in this project are treated as the Control Group (CG)
Summary
Kosova possesses a considerable energy potential of coal (lignite). Currently in Kosova, coal is excavated only in the Prishtina Pool, in superficial Mines in Bardh and Mirash, which lie in an open surface, 10-15 km far from Prishtina[1]. Dust (flying ash) and bottom ash are the main components of the environment pollution, which results from the industrial area of Obiliq. These components contain elements with high toxic potential such as: Pb, Cd, As, Be and Hg[1,2]. Most of the bilirubin is chemically attached to another molecule before it is released in the bile This "conjugated" (attached) bilirubin is called direct bilirubin; unconjugated bilirubin is called indirect bilirubin. The purpose of this study is to find the correlation between environmental pollution, smoking and the concentration of cadmium in blood[3], as well as the correlation between cadmium and Total Bilirubine (TB) and Direct Bilirubine (DB) in the blood of human population
