Details

This seminar presents a comprehensive study focused on the characterization, modeling, and management of volatile organic compounds (VOCs) emitted from urban fuel stations. The research encompasses field measurements, dispersion modeling, health risk assessment, and the exploration of cost-effective control strategies. Field measurements were conducted at multiple fuel stations to identify predominant VOCs and their dispersion characteristics. The results were used to estimate the cancer and non-cancer risks associated with VOCs at fuel stations. The analysis shows that continuous exposure to more than one year can result in both carcinogenic and non-carcinogenic risk (Hazard quotient = 0.045 and Cancer risk > 10-6) in workers and ten years of exposure can affect the neighbouring areas. A Lagrangian plume-based dispersion model, CALPUFF, was used to analyse the spatial distribution of pollutants from fuel stations. The results indicated a direct relationship of high concentrations reported with the average daily fuel sale and congestion at the stations. To address pollution concerns at fuel stations, cost-effective and practical control strategies were compared. Lab scale experimental studies using plants were carried out to evaluate efficiency of the technique. The presentation will provide a detailed analysis of these findings, emphasizing the significance of proactive measures for VOC management at urban fuel stations.
