They are the products of incomplete combustion of fossil fuels such as petroleum, coal and other organic materials from natural and anthropogenic sources in the rural and urban atmosphere. Eight PAHs were determined in PM10 collected at rural environment using Respirable sampler during winter, summer and post-monsoon seasons. The filters were extracted in ultrasonic bath with dichloromethane and analyzed by fluorescence technique. The total PAHs concentration varied from 2.67-17, 2.51-3.79 and 1.63-3.59 ng m-3 during winter, summer and post-monsoon season respectively. The benzo(a)pyrene and chrysene were found to be associated with particulate during all the seasons. The diagnostic ratio suggest that PAHs emissions were predominantly associated with coal, wood and biomass burning in rural environment. The higher toxic fraction observed during summer (53.8%) are probable human carcinogens associated with aerosols. Toxic equivalency factor (TEFs) of BaP estimated and expressed as BaPeq was low in concentration. The study could be of great significance for the planners while considering the environmental remedial measures. Copyright@ International Science Community Association
