Abstract

Aim: Present study was performed to investigate the possible human exposure to benzene through water pipe smoking, if any, in the selected rural population of Western Uttar Pradesh.

Methodology: Urine samples from water pipe smokers of both the sexes were collected and analyzed for urinary concentration of phenol, creatinine and malondialdehyde employing standard methods.

Results: The results showed that tobacco used by selected rural population contained traces of benzene in the range of 2.75 to 9.682µl ml^-1. Analysis of urine samples for phenol, a major metabolite of benzene, showed its increased concentrations in water pipe smokers than non smokers. Further, the effects of age and gender differences on the excretion of phenol were also recorded. Female water pipe smokers were found to be more vulnerable to benzene exposure than male smokers. Intriguingly, alcoholic water pipe smokers were less vulnerable than the non-alcoholic smokers.

Interpretation: It is concluded that respiratory, cardiac and haematological disorders caused by water pipe smoking might be attributed to long term benzene exposure amongst water pipe smokers. Large scale epidemiological studies are warranted in Indian rural population considering WHO (Framework Convention on Tobacco Control) regulations of water pipe smoking and tobacco products.
