Abstract: The present study revealed the post spray increase in particle mass concentration of fipronil in ambient air near the application site viz. PM1, PM2.5 and PM10 were about 51.2, 66.1 and 161.9 μg/m3, respectively. The ambient particle size distribution of pesticide at agricultural application site of 15 m2 with varying nozzle size diameters followed with Optical Particle Counter (OPC) detection showed finer particles ranging from 0.23 to 40 μm got deposited significantly in the human pulmonary region.
