Abstract

Due to industrial, vehicular and residential emission in Delhi, concentration of Black carbon (BC) emitted is
substantially high. Black carbon plays a major role in altering the earth’s climate and leads to adverse human
health. The current research estimates the concentration of Black Carbon, a light absorbing carbonaceous
aerosol at four locations of Delhi during 2017. The intra-seasonal variation indicated that the average
BC surface mass concentration was highest during winters around 26.27 ± 3.28μg/m3 followed by postmonsoon
and pre-monsoon season. As per the diurnal variation, minimum BC concentration was found
during the daytime between 12:00-17:00hrs due to enhancements in the MLH and increased convective
activity. The BC mass concentration exhibit positive correlation with PM2.5. This study will add significant
value to the current BC research literature.
