Ambient PM 2.5 pollution is a substantial threat to public health in global megacities. This
paper reviews the PM 2.5 pollution of 45 global megacities in 2013, based on mass …

Abstract Recently, PM 2.5 (atmospheric fine particulate matter with aerodynamic diameter≤
2.5 μm) have received so much attention that the observations, source appointment and …

The present study attempts to explore and compare the seasonal variability in chemical
composition and contributions of different sources of fine and coarse fractions of aerosols …

Due to its deleterious and large-scale effects on the ecosystem and long-range
transboundary nature, acid rain has attracted the attention of scientists and policymakers …

Delhi, the capital of India, suffers from heavy local emissions as well as regional transport of
air pollutants, resulting in severe aerosol loadings. To determine the sources of these …

Emissions of black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) from various
anthropogenic activities are often reported, yet cultural practices such as the multi-day …

This study presents results from size-resolved particulate matter (PM) source apportionment
in Ghaziabad, an industrial city adjoining New Delhi in the Indo Gangetic Plain (IGP). A full …

The Himalayas, which include delicate and unspoiled ecosystems, have the third-largest
glacier ice store in the world. Recent research reveals that anthropogenic and natural factors …

This study aims to assess the contribution of fossil-fuel combustion (BC ff) and biomass (or
wood) burning (BC wb) to wintertime black carbon (BC) concentrations in Delhi using the …

Abstract Fine ambient aerosols (PM 2.5) levels in the atmosphere are continuously
worsening over Delhi and National Capital Region (NCR) of India. Complete source profiles …
