“…Zn has different range of enrichment factor with the mean of 164.46 (Fig. 4 right axis), which is associated with activities mainly originated from anthropogenic sources such as traffic and industrial emission (Banerjee et al, 2015). Previous study by Zhang et al (2015) collected 24-h PM 2.5 samples every sixth day in Wuhan from August 2012 to July 2013, and the results about the EFs are traceable.…”

“…The characteristics of PM sources have been widely investigated in previous studies all around world, including China, as reviewed by (Karagulian et al, 2015), and several methods of receptor modeling have been used for identification and apportionment of PM (Viana et al, 2008). Enrichment Factor (EF) and Positive Matrix Factorization (PMF) are widely used because they only require observation data at the receptor site other than detailed prior knowledge of the sources and source profiles, and tools to perform these analyses are widely available (Schauer, et al, 2006;Yu et al, 2013;Gao et al, 2014;Banerjee et al, 2015).…”

The concentrations of PM 2.5 and trace elements with hourly resolution were measured during May 2014 in urban residential area of Wuhan, the biggest city in central China. During the period of measurement, the average temperature was approximate 25°C without domestic heating and cooling. The average concentration of PM 2.5 was 95.53 µg m -3 , which was higher than the limit of Ambient Air Quality Standard of China GB3095-2012 (75 µg m -3 , Level 2). A sand storm original from Northwestern China was also recorded. Concentrations of major trace elements (K, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Pd, Ag, Cd, Au, Hg, Pb, Co, Sn, Sb, Tl) were comparable to previous studies, except for Ba and Ca with more than doubled concentrations (103 ng m -3 , 1,792.49 ng m -3 ) due to the storm. Enrichment Factor (EF) and Positive Matrix Factorization (PMF) were employed to characterize the emission sources. The computation of EF showed that Zincs was highly enriched. Four sources, biomass burning (63.2%) might mainly related to power plants using biowaste burning and bio-related cooking activities, metallurgical and steel industries (14%), dust crustal (12.5%) and dust associated with vehicular traffic (10.4%), were identified in decreasing order of average percentage contribution to the PM 2.5 mass with the aid of trace elements. The orientations of emission sources were also addressed.

“…Aerosols are also associated with nutrient recycling and governing atmospheric chemistry (Kanakidou et al, 2018). Aerosol interaction with radiation mainly constitutes its radiative forcing of climate change (Bellouin et al, 2005;Bond et al, 2013) while it also modifies the climate by means of cloud formation processes (Seinfeld et al, 2016). Aerosol-radiation interaction necessitates understanding of spectrally varying aerosol optical properties, which are associated with particle size distribution, chemical composition, morphology, and mixing states.…”

Abstract. The large-scale emissions of airborne particulates from burning of agricultural residues particularly over the upper Indo-Gangetic Plain (IGP) have often been associated with frequent formation of haze, adverse health impacts, and modification in aerosol climatology and thereby aerosol impact on regional climate. In this study, short-term variations in aerosol climatology during extreme biomass burning emissions over the IGP were investigated. Size-segregated particulate concentration was initially measured and submicron particles (PM1.1) were found to dominate particulate mass within the fine mode (PM2.1). Particulate-bound water-soluble ions were mainly secondary in nature and primarily composed of sulfate and nitrate. There was evidence of gaseous NH3 dominating neutralization of acidic aerosol species (SO42-) in submicron particles, in contrast to crustal-dominating neutralization in coarser particulates. Diurnal variation in black carbon (BC) mass ratio was primarily influenced by regional meteorology, while gradual increase in BC concentration was consistent with the increase in Delta-C, referring to biomass burning emissions. The influence of biomass burning emissions was established using specific organic (levoglucosan), inorganic (K+ and NH4+), and satellite-based (UV aerosol index, UVAI) tracers. Levoglucosan was the most abundant species within submicron particles (649±177 ng m−3), with a very high ratio (> 50) to other anhydrosugars, indicating exclusive emissions from burning of agriculture residues. Spatiotemporal distribution of aerosol and a few trace gases (CO and NO2) was evaluated using both spaceborne active and passive sensors. A significant increase in columnar aerosol loading (aerosol optical depth, AOD: 0.98) was evident, with the presence of absorbing aerosols (UVAI > 1.5) having low aerosol layer height (∼ 1.5 km). A strong intraseasonality in the aerosol cross-sectional altitudinal profile was even noted from CALIPSO, referring to the dominance of smoke and polluted continental aerosols across the IGP. A possible transport mechanism of biomass smoke was established using cluster analysis and concentration-weighted air mass back trajectories. Short-wave aerosol radiative forcing (ARF) was further simulated considering intraseasonality in aerosol properties, which resulted in a considerable increase in atmospheric ARF (135 W m−2) and heating rate (4.3 K day−1) during extreme biomass burning emissions compared to the non-dominating period (56 W m−2, 1.8 K day−1). Our analysis will be useful to improve understanding of short-term variation in aerosol chemistry over the IGP and to reduce uncertainties in regional aerosol–climate models.

“…Significant uncertainties in estimating airborne particulate regional heterogeneity and its subsequent interactions with earth system have recently engrossed diverse groups of researchers to undergo extensive investigations (BANERJEE et al 2015). The approaches were mainly towards exploring dust radiative forcing, modifications in cloud microphysical properties, understanding roles in mediating physical and biogeochemical exchanges, ocean fertilization, food security and, in certain cases, more specifically on initiating adverse health impacts (BANERJEE and SRI-VASTAVA 2011;KUMAR et al 2015a, b).…”
