“…The study's results show that the lung function parameters (FEV1, FVC, PEFR, FEFR25% -75%) are significantly reduced in petrol pump workers (Group I) as compared to the values for these parameters in subjects belonging to Group II (Control group) (Table 2, Figure 3). Similar findings were observed in previous studies on pulmonary functions in petrol-pump workers resembling to studies undertaken by Chidri SV, Patil S et al [15]; Sharma H, Agarwal et al [16]; Balamurugan Santhalingam et al [17]; Praveen Bhardwaj et al [18]; Sumathi et al [19]. In an earlier study conducted by Sandip M Hulke et al 2012 [20], a significant reduction was seen in the FEV1 (Forced expiratory volume in 1 sec), FVC (forced vital capacity) in petrol pump workers who were exposed to more than 5 years.…”
