Abstract In this study, we have monitored 1-h (afternoon) ambient concentrations of size-segregated particles by means of 12 channels aerosol spectrometer (PALAS; welas® 2000) over 130 days in one year (2015/2016) from a highly polluted and populated region (Kanpur) in central Indo-Gangetic Plain (IGP). Average mass concentrations of PM2.5 (fine) and PM10-2.5 (coarse) varied from ∼40–160 and 30–67 μg m−3, respectively. PM mass size distribution analysis revealed multi-modal peaks in monsoon (tri-modal:
