Possible sources of ambient PM10 inside Jadavpur University Campus, Kolkata

High concentration of particulates in the university and research institutional campus can affect cognitive performance of students and researchers. However, studies on ambient particulate concentration in the campus of universities or research institutes are scarce. The ambient concentration of PM 10 was measured in the campus of Jadavpur University, Kolkata, during two different seasons (S1: Post-monsoon; S2: Winter) to identify major sources of pollutant here. Significant seasonal variation of ambient PM 10 was recorded in the campus. The average ambient PM 10 concentration was recorded higher in S2 compared to S1 of the study period. Morphological characteristics of PM 10 during the study period suggest that the roundness of particles was in the range of 0.66 to 0.68, whilst the mean spherical diameter suggests most of the PM 10 particles were
