TL;DR: A comprehensive review of black carbon measurements in India from a survey of >140 studies spanning 2002-2018 is presented in this paper, where the authors identify key areas for improvement, such as the need for long-term BC monitoring networks, especially in regions where estimated emissions are high but measurement coverage is low; the general lack of understanding, despite some recent reports, of BC aerosol mixing states, aging and direct climate effects in the Indian context; the need to shift from qualitative approaches of BC source apportionment to robust quantitative measures; and the prospects for coupled chemical-opt

TL;DR: Children are comparatively more vulnerable than adults to HM exposure, with the ingestion exposure pathway dominating over dermal contact and inhalation, according to cumulative hazard index (HI) and incremental lifetime cancer risk (ILCR).

TL;DR: Measurements of aerosol black carbon and aqueous and methanol-extractable brown carbon from a receptor location in the eastern Indo-Gangetic Plain under two aerosol regimes: the photochemistry-dominated summer and biomass burning post-monsoon and the BB regime are reported.

TL;DR: Spectroscopic compositional analysis of brown carbon (BrC) and humic-like substances (HULIS) in the Indian context under varying conditions of source emissions and atmospheric processing uncover a complex interplay of emissions and Atmospheric processing of carbonaceous aerosols in the IGP.

TL;DR: In this paper, the authors reported the first characterization of the aerosol brown carbon composition in the Indian context using excitation emission matrix (EEM) fluorescence spectroscopy coupled with parallel factor (PARAFAC) analysis.
