“…In environmental studies, principal component analysis (PCA) and hierarchical cluster analysis (HCA) are the most commonly used multivariate statistical methods (Bahloul, 2020;Chalvatzaki et al, 2019). Thus, trace elements (As, Cd, Ni, Pb) originated from PM 10 were classified by using the Minitab17 statistical software, hierarchical cluster analysis method (Centroid Linkage, correlation coefficient distance), and the results were presented in a dendrogram.…”

In the present study, the concentrations of trace elements in PM10 were determined and analyzed at 115 monitoring stations in Romania throughout the period 2009–2018. The spatiotemporal distribution of trace element concentrations of PM10, the source apportionment and health impact assessment, was carried out. The results showed a very high multi-annual mean concentration for PM10 and trace elements as well. The multiannual average concentration of PM10 was higher by 29.75% than the World Health Organization recommendation. All studied air pollutants showed a decreasing trend during the studied years, showing with 17.84%, 50.21%, 43.36%, 11.27%, and 72.09% lower values for PM10, As-, Cd-, Ni-, and Pb-, respectively, due to environmental regulations. To assess the human health impact, the hazard quotient (HQ) and cancer risk (CR) were calculated using the health risk model developed by the US Environmental Protection Agency (EPA). The Cd and Ni might present a non-carcinogenic risk to both adults and children; however, the hazard quotient values are higher than the safe limit, with 9.53 and 1.93, respectively. In addition, our study results revealed that the inhalation of As, Cd and the dermal absorption of all studied trace elements were considered as the most important risk factors for developing cancer, especially in case of adults.

“…A large number of studies were focused on toxic trace elements, such as As, Co, Cd, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Se, and Zn, etc., in atmospheric deposition with particular attention to their distribution, fluxes, and sources [11][12][13][14][15][16][17][18][19][20], and recently some other studies have focused on the pollution and health risks of varied toxic trace elements in atmospheric deposition with various pollution indexes and hazardous quotients and hazardous indices. Using multiple indices to assess the pollution extent of toxic trace elements in atmospheric deposition has become a common approach by researchers [21][22][23][24][25][26][27][28][29][30][31][32]. In health risk assessment of toxic trace elements, the method recommended by the US Environmental Protection Agency is widely used in regards to atmospheric deposition [33][34][35].…”

A total of 56 atmospheric deposition samples were collected on a yearly basis from the Baicheng-Songyuan areas, Jilin Province, Northeast China. Each sample was subdivided into wet (soluble) and dry (insoluble) fractions, and the concentrations of toxic trace elements including As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Se, and Zn in both fractions were analyzed. The bulk fluxes and ecological and human health risk of these toxic trace elements in atmospheric deposition were evaluated. The bulk deposition fluxes of toxic trace elements decreased in the order of Mn > Zn > Cr > Pb > Cu > Ni > As > Co >Mo > Cd > Se > Hg. The fluxes of toxic trace elements in dry fraction accounted for 74.7–99.9% of their bulk deposition fluxes, indicating that the atmospheric deposition of toxic trace elements in the study area is predominantly dry atmospheric deposition. The mean values of the geo-accumulation index (Igeo) and enrichment factor showed moderately heavy contamination with Cd via dry atmospheric deposition, but no contamination from other toxic trace elements; Cd and Hg in dry atmospheric deposition were in the moderate to considerable ecological risk levels, while other trace elements were at low ecological risk levels. The health risk assessment showed that the effects of toxic trace elements in dry atmospheric deposition via three exposure pathways were in the order of ingestion > inhalation > dermal contact for adults and children. The mean values of hazard quotient (HQ) and hazard index (HI) of toxic trace elements via three pathways were less than one, indicating that their non-carcinogenic risks in dry atmospheric deposition may be low or negligible for adults and children. The mean values of carcinogenic risk (CR) and total carcinogenic risk (TCR) of As and Cr via the three pathways for adults and children were between 10−6 and 10−4, indicating that the carcinogenic risk levels of As and Cr were tolerable or acceptable, and the mean TCR value of Cd through the three pathways for adult and children was less than 10−6, implying that the carcinogenic risk level of Cd was negligible. Mn, Ni, Cr, and Co in dry atmospheric deposition were mainly contributed from the crustal sources, while As, Cd, Cu, Hg, Mo, Pb, Se, and Zn in dry atmospheric deposition were derived from both crustal and anthropogenic sources. The results obtained in this study advocate the necessity for monitoring atmospheric deposition in some rural areas, and also provide a scientific basis for controlling contamination posed by toxic trace elements in dry atmospheric deposition.
