Abstract
Consumption raw oil may cause different pollutants which may have various environmental and health effects upon those occupationally exposed workers in industrial activities that used this energy.
A total of 60 workers from Qubiasa cement factory and 10 individuals from well away sites were examined during this work for vanadium blood content after being subjected to personal interview using questionnaire sheet consisting information health background and any signs that may be accounted for certain organic and psychological syndromes.
The results have found that vanadium blood content in occupationally exposed sample was varied from 9.07 ± 3.73 µg/cm³ to 16.89 ± 7.79 µg/cm³ and in environmentally exposed sample was 6.82 ± 1.69 µg/cm³ while in control sample was 4. 42 ± 0.7 µg/cm³. This, blood vanadium content was significantly (P ≥ 0.05) related to the exposure periods.
Also, this work has shown that several health symptoms such as teeth decay , hair fallen , weight fluctuation and vision impairment in most of those occupationally exposed workers while such signs were not found in both environmental and control samples Interestingly, the number of health syndromes that tested workers had, were found to be due ( P ≥ 0.05 ) to exposure times and not to the worker age.
However, the most occupationally examined workers have shown several psychological problems such as stress, depression and malaise. Finally, this study may need further investigations on similar samples to support a conclusion that these signs may be accounted for early diagnosing of any health sever or even lethal diseases to avoid such various diseases infections by different air contaminants caused by raw oil consumptions.
