The impact of pollution due to gas flaring on men native to Ebocha in the Niger Delta Area was investigated. Forty apparently healthy men between 30 to 50 years were screened; twenty from Ebocha and twenty from Uturu a control location with no history of petroleum hydrocarbon (PHC) pollution. Standard analytical procedures were used in the determination of the concentrations of the parameters. Parameters investigated were haematological: haemoglobin (HB) concentration, packed cell volume (PCV), white blood cell (WBC) count, percentage of lymphocytes, monocytes and neutropphils; renal function: urea, creatinine, K+, Na+,Cl– and HCO3– Results obtained revealed that mean values of haemoglobin, packed cell volume, white blood cell counts and neutrophils (10.22±1.40 g/dl, 31.20±4.08%, 2.98±0.16×/µl 43.90±2.08%) respectively were substantially lower in men from Ebocha when compared to those of men from Uturu (13.20±1.29g/dl, 39.7±3.84%, 4.6±0.98±×103/ul and 60.00±7.48% respectively. The mean value counts of lymphocytes of the men from Ebocha (55.40±7.87%) were significantly higher than those of the men from Uturu. However, the mean values of monocytes were essentially similar for men from both locations. Of the renal function parameters, only creatinine and urea gave values in mg/dl (1.31±0.38 and 46.41±5.03) respectively that were significantly (p<0.05) higher in men from Ebocha when compared to values in mg/dl (0.81±0.37 and 11.81±2.62 respectively for men from the control location. The mean concentrations of sodium and potassium ions of the men from Ebocha were significantly (p<0.05) higher than those of men from Uturu. However, there was no significant (p<0.05) difference in the mean concentrations of chloride and bicarbonate ions of men from the two sites. Thus, these findings show that haematological and renal function parameters of men from Ebocha were altered, possibly due to chronic exposure to gas flaring in that environment.
