Exposure to Vehicular Pollution and Respiratory Impairment of Traffic Policemen in Jalgaon City, India

The ambient air quality monitoring was carried during the May 2003 to April 2004 along the (NH-6) passing through Jalgaon city. The average concentration of SOx 64 μg/m3, NOx 58 μg/m3, particulates (>10 μ) 515 μg/m3 and respirable dust particulates 224 μg/m3 was reported at Prabhat during the study period (May 2003-April 2004). This location represents the major highway crossings (four) in the study area. The present investigations are on the survey of health status and lung function of traffic policemen exposed to the inferior air quality as observed on the highway crossings. The spirometric analysis of traffic policemen shows significant variation in Peak Expiratory Flow Rate (PEFR), Forced Expiratory Volume in one second (FEV1) and Forced Vital Capacity (FVC). The parameters were significantly affected in the traffic policemen as against the control group of population. It reveals significant respiratory impairment in the traffic policemen due to exposure to vehicular pollution. The study suggest the compulsory use of personal protective equipment (nose mask) by the traffic policemen during duty hours will help for the protection from vehicular pollution. The regular periodic health checkup is required to understand the impact of vehicular pollution on the health of traffic policemen.
