A nationwide study was carried out to develop air pollution source profiles specific to India. Chemical speciation profiles are reported for 27 major non-vehicular sources of particulate matter (combustion and non-combustion) in six cities in India viz. Bengaluru, Chennai, Delhi, Kanpur, Mumbai and Pune. PM10 and PM2.5 samples were collected from these sources using three different modes of sampling viz. dilution, resuspension and source dominated sampling, depending on the nature of the source. Filter samples were analyzed for mass by gravimetric analysis, elements by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), water soluble ions by ion chromatography and elemental (EC) and organic carbon (OC) by thermal/optical reflectance. Reported profiles include 39 elements, 12 ions, EC and OC. Developed profiles are compared with similar profiles that have been reported previously. •PM10 and PM2.5 source profiles are developed for 27 major sources in six Indian cities.•Reported profiles include combustion and non-combustion point sources and area sources.•Speciation profiles are comprised of 39 elements, 12 ions, elemental (EC) and organic carbon (OC).•Developed profiles were compared with similar profiles reported from other countries.
