Environmental hazard in a work place is an inevitable experience especially when it has to do with working in a filling stations where volatile and combustible substances like petrol, diesel and kerosene are dispensed via PMS and other channels of distribution or outlets and in the process pollute or saturate the air with hydrocarbons. Individuals working in a petrol station pose different risk of exposure to these xenobiotics that enter the body via different means (inhalation, ingestion and skin or eye contact) and could be detrimental to the body system resulting to death if not properly handled. This research was aimed at assessing some biochemical indicators of occupational hazard in fuel pump attendant from selected service stations in Ihiala, Anambra state. A total of eighty apparently healthy subjects (40 males and 40females) aged between 28-35 years volunteers participated in the study. Each gender was further categorized into two groups of 20 each for control (unexposed workers) and exposed pump attendants respectively. The pump attendants that volunteered for this study had spent an average of 5-6 years on the job. Blood samples were collected from the volunteers with their informed consent and selected biochemical parameters such as liver function test (ALP, AST ALT), kidney function test (urea, creatinine and uric acid), protein profile (total protein and albumin), and electrolyte levels were investigated using standard methods. The result of the investigations showed that urea and creatinine level of exposed female pump attendants (5.80±0.02 mg/dl and 82.50±2.15 mg/dl)were significantly higher (P<0.05) than unexposed female pump attendants (5.00±0.45mg/dl and 58.00±0.11 mg/dl respectively). Serum sodium (Na+ ) electrolyte levels of exposed male and female exposed pump attendant (143.00±1.05 and 141.00±1.25 mmol/L respectively) were significantly higher (P<0.05) compared to Na+ electrolyte levels in male and female unexposed workers (138.00±0.14 mmol/L and 139.50±2.11 mmol/L respectively) while the chloride ion level in male and female pump attendants were higher compared to male and female unexposed workers. Alanine transaminase and aspartate transaminase (ALT and AST) levels of male and female exposed pump attendant were higher than that in male and female unexposed pump attendant. Petroleum fumes are therefore environmental pollutants that could have serious consequences on biochemical parameters in petroleum product exposed individuals. Therefore, health Safety and Environmental training is recommended for petrol station workers on regular basis to improve their safety and create awareness on the dangers inherent associated with filling station workers exposed to petrol fumes.
