“…The second factor exhibited high loading for the anthropogenic-derived metals Cu, Pb, V, As, Ni and Cr, which might be identified as fossil fuel combustion source. Previous studies have suggested that As, Pb and V mainly derived from coal and oil combustion (Li et al, 2010;Xu et al, 2012), and Cr and Ni can be considered as indicators of emission from fuel combustion and vehicle emission (Tian et al, 2012). This source contributed 13.8% to PM 10 .…”

To investigate trace element pollution of PM 10 in urban Chengdu, a Southwest megacity of China, as well as to assess the human health risks caused by exposure to PM 10 , we analyzed ambient PM 10 samples collected at an urban site in Chengdu from November, 2014 to October, 2015. The annual mean concentration of PM 10 in the sampling period was 173.6 ± 77.9 µg m -3 , which is 2.5 times higher than the national recommended standard of 70 µg m -3 . The mean metals content in PM 10 was in the following order:The concentration of As in PM 10 was observed to be 2.9 times higher than the secondary level recommended by the China National Ambient Air Quality Standard (GB3095-2012), whereas the concentrations of other metals were within the limit. Enrichment factor analysis indicated that As, Pb, Zn, Cu, Cd, and Sb mainly originated from anthropogenic sources. Five factors were identified by positive matric factorization (PMF) model. The sources identified were soil dust (48.4%), road dust (19.4%), fossil fuel combustion (14.9%), electroplating industry (13.8%), and metallurgy industry (3.5%). Particle morphology and chemical composition analysis revealed six major particle types, namely aluminosilicate, sulfur-containing, carbon-containing, chlorine-containing, biomass burning, and metal particles. The results of the health risk assessment indicated that Cr can be carcinogenic to both children and adults, and other trace elements were determined to be below the legislation threshold (Environmental Protection Agency limit values), except for As, which was observed to be above the threshold.

“…The percent of variance explained by each significant factor was calculated by using the software (SPSS 10.0) with measured heavy metal as variables. As shown in Table 1, in PM 2.5 primary factor 1, Cr, and Ni have the highest values (0.930 and 0.929, respectively); this represents a contribution of anthropogenic sources of motor vehicles, coal, and oil burning (Tian et al, 2012). In main factor 2, Cu and Mn have the highest values (0.906 and 0.880, respectively) which represent the contributions of iron and steel industry, smelting, and automotive brake friction Tan & Duan, 2013).…”

“…The correlation coefficient (R 2 ) value between Ni and Cr was 0.598 (P \ 0.01), suggesting that part of them were probably derived from the same source. The coal combustion was the leading source of Ni contamination (Tian et al 2012). Thus, the significant correlation among As, Cr, Cu, Mn, Ni, Pb and Zn may come from traffic emissions and coal combustion.…”

Twenty trace elements in fine particulate matters (i.e., PM2.5) at urban Chengdu, a southwest megacity of China, were determined to study the characteristics, sources and human health risk of particulate toxic heavy metals. This work mainly focused on eight toxic heavy metal elements (As, Cd, Cr, Cu, Mn, Ni, Pb and Zn). The average concentration of PM2.5 was 165.1 ± 84.7 µg m(-3) during the study period, significantly exceeding the National Ambient Air Quality Standard (35 µg m(-3) in annual average). The particulate heavy metal pollution was very serious in which Cd and As concentrations in PM2.5 significantly surpassed the WHO standard. The enrichment factor values of heavy metals were typically higher than 10, suggesting that they were mainly influenced by anthropogenic sources. More specifically, the Cr, Mn and Ni were slightly enriched, Cu was highly enriched, while As, Cd, Pb and Zn were severely enriched. The results of correlation analysis showed that Cd may come from metallurgy and mechanical manufacturing emissions, and the other metals were predominately influenced by traffic emissions and coal combustion. The results of health risk assessment indicated that As, Mn and Cd would pose a significant non-carcinogenic health risk to both children and adults, while Cr would cause carcinogenic risk. Other toxic heavy metals were within a safe level.
