Evaluation of Biomarkers in Workers Exposed to Air Pollutants in Oil Refineries
Keywords:air pollution; oil refinery workers; oxidative stress
Air pollution is nowadays a complex problem due to industrial prosperity. Among the chemical industry,
oil refineries have been identified as major emitters of a wide range of pollutants, the workers of the oil
refinery are exposed to a great variety of toxic compounds. Air pollution is the main environmental cause
of human disease and death. Therefore, it is necessary to develop early warning signals or biomarkers
that convincingly reflect adverse biological responses towards anthropogenic environmental toxins
even at minute concentrations. This work aims to study the effects of exposure to the air pollution of oil
refinery, on the parameter blood, TNF-a, antioxidant glutathione peroxidase(GPx), and oxidative stress
malondialdehyde (MDA), in workers of the oil refinery. Results showed that exposure to air pollution
in the oil refinery lead to( a significant increase in levels Hb, WBC, Lymphocyte, TNF-a, and MDA,
decrease levels of GPx) P<0.05. And non –significant in( RBC, HCT, Neutrophils ) P>0.05 in workers,
compared to healthy control.
