“…8. We could see the PM10 concentration peak on January [25][26]2009 precisely happened during the fireworks display period, and the higher concentrations persisted for several hours with adverse dispersing meteorological conditions, such as the lower wind speed and humidity. According to the regulations, firework displays were in legal during the Spring Festival Holiday (from January 23 to February 9, 2009) in this city, and it was subjected awful air quality most of this period.…”

“…The unpleasant ambient air quality in S4, on the one hand, might be the result of combustion fossil fuels. On the other hand, it might be affected by the discharge of chemical industry, which was identified as one of the main sources of particulate matters including PM10 [20,25]. The air quality of S3, located in the center of this city, was relative better than that of S2 and S4 due to fewer particles from industrial and commercial activities.…”

Descriptive statistics methods were used to study the spatiotemporal variations and sources of ambient particulate matter (PM10) in Luzhou, China. The analyzed datasets were collected from four national air quality monitoring stations: Jiushi (S1), Xiaoshi (S2), Zhongshan (S3), Lantian (S4) over the period of 2003-2012. This city was subjected serious PM10 pollution, and the long-term annual average PM10 concentrations varied from 76 to 136 μg/m 3. The maximum concentration was more than 3-fold of the annual average (40 μg/m 3) issued by EPA-China for the ambient air quality. General temporal pattern was characterized by high concentrations in winter and low concentrations in summer, and general spatial gradient was in the reduction order of S2 > S4 > S3 > S1, which were both due to different particulate contributors and special meteorological conditions. The source apportionment indicated that vehicular emissions, road dusts, coal burning and chemical dusts were the major contributors of the identified PM10 pollution, and the vehicular emissions and the road wear re-suspended particles dominated the heavy PM10 pollution in recent years. Two other potential sources, agricultural and celebration activities could decrease the air quality in a short term. Finally, some corresponding suggestions and measures were provided to improve the air quality.

“…During 2005-2007, most of the studies were reported in the region of IGP with annual PM2.5 ranges from 56.2 µg m -3 to 136 µg m -3 and annual PM10 range from 134 µg m -3 to 306 µg m -3 [33,34]. 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].…”

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.

“…Industrialization, urbanization, and increases in the population are resulting in pollution of the environment (Nicolas et al, 2008). Deterioration of urban air quality has become an increasing and widespread concern throughout the world (Singh and Sharma, 2012). PM 2.5 , the fine air particle with an aerodynamic diameter less than 2.5 μm, is the pollutant with the most undesired health effects (Brook et al, 2010;Zhang et al, 2018).…”

Exposure to fine ambient particulate matter (PM 2.5) is known to be associated with cardiovascular disease. To uncover the molecular mechanisms involved in cardiovascular toxicity of PM 2.5 , we investigated alterations in the protein profile of human umbilical vein endothelial cells (HUVECs) treated with PM 2.5 using two-dimensional electrophoresis in conjunction with mass spectrometry (MS). A total of 31 protein spots were selected as differentially expressed proteins and identified by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) MS. The results demonstrated that DNA damage and cell apoptosis are important factors contributing to PM 2.5-mediated toxicity in HUVECs. It is further proposed that PM 2.5 can inhibit superoxide dismutase (SOD) activity and increase reactive oxygen species (ROS) and malonaldehyde (MDA) production in a concentration-dependent manner. Induction of apoptosis and DNA damage through oxidative stress pathways may be one of the key toxicological events occurring in HUVECs under PM 2.5 stress. These results indicated that the toxic mechanisms of PM 2.5 on cardiovascular disease are related to endothelial dysfunction.
