“…This finding is consistent with that of Hueglin et al (2005), which was undertaken in Switzerland. Moreover, throughout the two-year period, the mean concentrations of PM 2.5 at all sampling sites in northern Taipei was 17.7 ± 13 µg m -3 , lower than that reported by recent relevant studies: 29.3-102.2 µg m -3 in central Taiwan (Cheng et al, 2008), 43.2 ± 20 µg m -3 in southern Taiwan (Cheng et al, 2014), 90.3 ± 55 and 95.5± 42 µg m -3 in Shanghai (Feng et al, 2009), 106-131 µg m -3 in Hebei Xing et al, 2017) and 60.7 ± 20 and 187 ± 48 µg m -3 in India (Panda et al, 2015). (range: 14.8-59.4 fg I-TEQ m -3 ) at Urban Site 1 and 11.0 ± 2.70 fg I-TEQ m -3 (range: 8.25-13.6 fg I-TEQ m -3 ) at Background Site.…”

Winter monsoonal air masses traveling from Inner Mongolia to downwind nations can transport cold temperature and air pollutants. This study investigated the effects of the long-range transport (LRT) of air pollutants by northeastern monsoons and local pollution (LP) episodes on atmospheric PM 2.5 , polychlorinated dibenzo-p-dioxin (PCDD), and polychlorinated dibenzofuran (PCDF) concentrations in northern Taiwan during the winters of 2014 and 2015. Air samples were collected in rural (Rural Site 1 was mountainous; Rural Site 2 was coastal) and urban (Urban Site 1 was urban; Urban Site 2 was suburban) areas in northern Taiwan as well as at a background site (Lulin Mountain) in central Taiwan. Atmospheric PCDD/F concentrations measured at different sites ranged from 11.0 ± 2.70 to 39.7 ± 22.7 fg international toxicity equivalency quantity (I-TEQ) m -3 in 2014 and 7.99 ± 5.58 to 17.5 ± 12.3 fg I-TEQ m -3 in 2015. During LRT and LP, the proportion of PCDFs was higher than that of PCDDs. Rural Site 1 (122 pg I-TEQ g

“…Low height of mixing and stable atmosphere, which limit the vertical movements of air masses are, next to low wind speeds, primary factors responsible for episodes of elevated pollutant concentrations in the air (including PM 10 and PM 2.5 ) in many cities around the world, observed particularly in the winter [4,11,17,18,28,29,35,38].…”

“…Further, in three years (2008-2010), particulate fractions have shown increasing trend with the ranges of 63.4-198 µg m -3 (PM2.5) and 107 -271 µg m -3 (PM10) [35][36][37][38][39][40][41][42][43][44][45][46][47][48]. Between 2011 and 2015, the ranges of ambient PM2.5 and PM10 were found to be 43.7-215 µg m -3 and 87.9-355 µg m -3 , respectively [27,34,[49][50][51][52][53][54][55][56][57].

“…The major component of PM is carbonaceous aerosols. Total carbonaceous matter (TC) (sum of OC and EC) accounted for > 50 % of PM2.5 emissions in most of the research articles with OC/ EC ratio > 1 [54,[58][59][60][61][62] attributed to the fact that Indian ambient carbonaceous matter contains larger content of primary and secondary organic carbon. A 15 years averaged concentration of selected chemical components of ambient PM2.5 in India (Fig.…”

From the last few decades, the studies related to source apportionment of airborne particulate matter (PM) have gain more attention among global scientific community including India. The outcomes from these studies are utilized for better and effective policy design to control pollution level. However, these source apportionment results have been shown much divergence for India due to differences in sampling technique, analytical methods, selection of source maker chemical species, and application of mathematical and statistical methods, etc. So, this review presents the trends and advancement of ambient PM2.5 and PM10 particles source apportionment studies for special perspective of India for better understanding of these above highlighted issues. The ambient PM2.5 and PM10 source investigations related earlier research articles and reports from various regulatory agencies which published between the years of 2000 to 2015 for India were selected and categorized into three plateau regions for review. Few studies were carried out with source apportionment centered objectives for ambient PM2.5 and PM10 mass concentration and maximum reported studies were confined to address aerosol mass concentration and its chemical characterization to evaluate spatiotemporal variation. Higher number of data were reported for the Indo-Gangetic plain (IGP) region during the year of 2005 to 2007 with the annual average range from 56.2 to 136 μg m-3 and 134 to 306 μg m-3 for PM2.5 and PM10, respectively. The annual average for ambient PM2.5 and PM10 levels has been raised about 50 % and 14%, respectively during the first fifteen years of 21st century in Indian environment. The carbonaceous matter (TC) has been found as the major component of PM mass in Indian environment. The carbonaceous matter was reported as major abundant species which was about > 50 % of PM2.5 mass concentration with OC/EC ratio > 1. The distribution of different PM2.5 chemical components were reported to be 7 ± 15 %, 1 ± 3 %, 46 ± 49 %, 34 ± 24 % and 12 ± 9%, for crustal elements (Al, Ca, Fe, Na, Mg, Si), trace elements (Cr, Zn, Ni, Cu, Cd and Pb), ionic (Na+, NH4+, Cl−, NO3− and SO4 2−) and carbonaceous matter fractions, respectively. The following six major contributing sources for ambient PM2.5 pollution in India have been found during the assessment period i.e. road traffic emissions as the major contributor, followed by marine aerosols/sea salt, crustal, industrial emissions, secondary aerosols and biomass burning emissions.
