This study was conducted in the PanvelTaluka of Raigad district, Maharashtra, to investigate the presence of Benzo[a]pyrene (B[a]P) within Particulate Matter (PM) and its sources. B[a]P is known for its widespread environmental distribution and persistence, posing risks to human health. The research focused on assessing B[a]P concentrations associated with PM emissions in diverse settings such as industrial zones, roadsides, residential areas, and agricultural lands. Sampling was conducted in 2022, both before and after the monsoon seasons, revealing higher average B[a]P concentrations during the pre-monsoon period compared to the post-monsoon period. Specifically, average B[a]P concentrations ranged from 22.88 ng/m³ to 94.55 ng/m³ pre-monsoon, and from 18.57 ng/m³ to 54.58 ng/m³ post-monsoon. Significant correlations (r=0.7-0.9) were observed between B[a]P levels and PM10 & PM2.5. The study found varying levels of B[a]P among different sampling sites, with concentrations generally highest in industrial areas, followed by roadsides, residential areas, and agricultural regions. Literature reviewed indicated that atmospheric conditions played a crucial role in the deposition of B[a]P. Additionally, backward trajectory analysis demonstrated long-distance transport of B[a]P to the study area, contributing to higher concentrations alongside local emissions.
