Abstract
Background: There are many petrol filling stations in an urban and semi-urban area of Hooghly District of West Bengal and a large number of attendants work in these stations. They are constantly exposed to petrol vapour as well as motor vehicle fuel which might lead to respiratory problems in workers.
 Objectives: To assess the pulmonary function of Petrol Filling Workers of West Bengal and to evaluate the effect of duration of exposure on those Parameters.
 Methods: This is a cross-sectional study design. Pulmonary function test was done among 52 Petrol filling workers and 20 office workers of college as well as students of those institutions of Hooghly district and nearby area of Kolkata by simple random sampling method. Pulmonary function parameters were assessed by digital expirograph (Spirovit SP1) and Wright’s Peak Flow Meter. A questionnaire was filled up by invigilator regarding years of exposure, respiratory abnormalities, smoking habit and any other diseases. All the study protocol was approved by the Human Ethical Committee of Raja Peary Mohan College and Serampore college
 Results:-From the above survey, it was observed that respiratory volume and capacities significantly(p<0.05-0.001) decreased with an increase in years of exposure. Odds ratios of different respiratory diseases (OR ranges from 1.12-3.12) indicate the risk of developing a cough, phlegm, asthma, skin diseases among petrol filling workers.
 Conclusion:- Safe threshold level of benzene VOC exposed in Petrol station is needed to protect the health of workers. Besides periodic health check-up, use of protective gadgets, improvement of technology and control strategies to reduce air emission of benzene VOC is essential to protect the health of Petrol filling workers of West Bengal.
