“…The higher SPM concentration during the winter season may be attributed to the use of more fuel during the winter season in industrial and automobile, thus the associated emissions are increased. Moreover, the relatively low wind speed and higher frequency of inversions occurring in winter lead to a decrease in the dispersion of SPM in the atmosphere, which, in turn, helped in the buildup of pollution concentrations to the higher levels . Concerning the average elemental concentrations of V and Ni, it can be observed from Table that they are similar between the two sampling areas, which suggests the similarity of any anthropogenic sources associated with these elements.…”

“…), incineration, resuspension of road and construction dust, and local emissions including mobile source emissions and motor vehicles represent the major sources of SPM . Long‐term effects of SPM on humans, plants, and animals have been previously reported . Particulate matter tends to persist in the atmosphere where it can undergo chemical reaction and transported from its sources over long distances to pristine areas of the environment .…”

Due to the remarkable increasing of the mass concentrations of suspended particulate matter (SPM) as an air pollution indicator in Greater Cairo‐Egypt, regular sampling during autumn 2014 and winter 2014/2015 seasons has been performed from industrial and residential areas. It was found that the average mass concentrations of the SPM collected from residential and industrial areas are equal to 531 ± 198 and 912 ± 230 μg/m3, respectively. These quantities are much higher than the maximum allowance level, especially for the industrial area. By utilizing three secondary targets, energy dispersive x‐ray fluorescence working under vacuum environment was used for elemental analysis of 19 elements namely; Na, Al, Si, S, Cl, K, Ca, Ti, V, Mn, Fe, Ni, Cu, Zn, Pb, Se, Br, Rb, and Sr. The present optimized selective excitation energy dispersive x‐ray fluorescence analysis has considerably enhanced the analytical range with respect to our previous similar studies, including low Z elements such as Na, Al, S, and Cl and attaining lower detection limits in the range of ng/m3. Remarkable high elemental concentrations were determined for most of the detected elements from the industrial area samples, strongly indicating the influence of the industrial and anthropogenic activities. The average percentages of the mass concentration of the detected inorganic elements account only for 3.2% and 10.5% of the total mass concentration collected from the residential and industrial areas, respectively, thus directly indicating that the content of organic pollutants in SPM is the dominant contribution.

“…Soil and/or dust re-suspension is an important source for TSP4849, and the organic carbon associated with dust deposition has been demonstrated as an input for DOM in alpine lakes650. The enhancement of WSN in summer periods might be related to the formation of water soluble inorganic nitrogen (WSIN, e.g., NO 3 − ) by the reaction of mineral aerosols with gaseous nitric acid5152.…”

Atmospheric aerosols have been shown to be an important input of organic carbon and nutrients to alpine watersheds and influence biogeochemical processes in these remote settings. For many remote, high elevation watersheds, direct evidence of the sources of water soluble organic aerosols and their chemical and optical characteristics is lacking. Here, we show that the concentration of water soluble organic carbon (WSOC) in the total suspended particulate (TSP) load at a high elevation site in the Colorado Rocky Mountains was strongly correlated with UV absorbance at 254 nm (Abs254, r = 0.88 p < 0.01) and organic carbon (OC, r = 0.95 p < 0.01), accounting for >90% of OC on average. According to source apportionment analysis, biomass burning had the highest contribution (50.3%) to average WSOC concentration; SOA formation and motor vehicle emissions dominated the contribution to WSOC in the summer. The source apportionment and backward trajectory analysis results supported the notion that both wildfire and Colorado Front Range pollution sources contribute to the summertime OC peaks observed in wet deposition at high elevation sites in the Colorado Rocky Mountains. These findings have important implications for water quality in remote, high-elevation, mountain catchments considered to be our pristine reference sites.

“…Soil dust events are spurious by nature because they are very dependent on local meteorology (Vallius et al 2003). In fact, the resuspension intensity depends on the wind velocity, temperature, and humidity, and there is no systematic relationship between adhesion to surfaces and these factors (Dordević et al 2004). Moreover, in addition to the local contribution, the presence of Fe in atmosphere is related to long-range transport events like desert dust transport.…”

The Fisher-Shannon information plane (FS), defined by the Fisher information measure and the Shannon entropy power, is proposed to investigate the complex dynamics of the concentration of three heavy metals (Cd, Fe, and Pb) in four different fractions of particulate matter data, recorded in Tito, a small industrial area of southern Italy. In the FS plane, the three metals are aggregated in three different clusters, characterized by different degrees of order. This result is related to different sources of the three metals.
