Environmental and occupational studies are necessary for managing risk in exposed humans. Although hazardous effects of gasoline were initially considered in occupational settings, the current study aimed to explore the effects of gasoline on blood, kidney and liver indices in unregulated gasoline traders. The case group was gasoline traders who directly exposed to the gasoline compounds. The data were collected through a medical assessment and obtaining a 10 ml venous blood sample. Complete blood count, blood urea nitrogen (BUN), creatinine (Cr), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (AP) were tested. The hemoglobin, hematocrit, mean corpuscular hemoglobin concentration, BUN, AST, ALT, AP levels were higher in the exposed group. However, the Cr level was significantly lower in the exposed group compared to the non-exposed ones. Most of parameters were significantly different between two groups. Proper controlling and training may limit the burden of future chronic disorders costs at risk populations.
