“…4, the mean EFs of Ca, Ba, K, Mn, V and Cr are below 10, which suggest that these elements would be more likely originated from natural sources such as crustal soil and re-suspended soil and have no obvious enrichment in particle matter (Xu et al, 2013b). It is worth to notice for K the 90% percentage is over 10, and there are outliers over 10, and K is associated to biomass burning as reported in many other studies (e.g., Hleis et al, 2013;Almeida et al, 2015). Zn has different range of enrichment factor with the mean of 164.46 (Fig.…”

The concentrations of PM 2.5 and trace elements with hourly resolution were measured during May 2014 in urban residential area of Wuhan, the biggest city in central China. During the period of measurement, the average temperature was approximate 25°C without domestic heating and cooling. The average concentration of PM 2.5 was 95.53 µg m -3 , which was higher than the limit of Ambient Air Quality Standard of China GB3095-2012 (75 µg m -3 , Level 2). A sand storm original from Northwestern China was also recorded. Concentrations of major trace elements (K, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Pd, Ag, Cd, Au, Hg, Pb, Co, Sn, Sb, Tl) were comparable to previous studies, except for Ba and Ca with more than doubled concentrations (103 ng m -3 , 1,792.49 ng m -3 ) due to the storm. Enrichment Factor (EF) and Positive Matrix Factorization (PMF) were employed to characterize the emission sources. The computation of EF showed that Zincs was highly enriched. Four sources, biomass burning (63.2%) might mainly related to power plants using biowaste burning and bio-related cooking activities, metallurgical and steel industries (14%), dust crustal (12.5%) and dust associated with vehicular traffic (10.4%), were identified in decreasing order of average percentage contribution to the PM 2.5 mass with the aid of trace elements. The orientations of emission sources were also addressed.

Steel production is an important source of particulate matter emission. In this study, both filterable and condensable fine particulate (PM 2.5 ) emissions from an electric arc furnace (EAF) and four integrated iron and steel plants were measured. Chemical compositions including water soluble ions and metal elements of these two types of PM 2.5 were analyzed. The results show that filterable PM 2.5 concentrations emitted from sintering, coke making, blast furnace, basic oxygen furnace (BOF) and EAF are 1.01, 0.37, 0.16, 0.15 and 0.28 mg/Nm 3 , respectively. Sintering has the highest filterable PM 2.5 emission concentrations. Condensable PM 2.5 concentrations emitted from the above processes are 65.3, 89.7, 3.84, 1.32 and 2.02 mg/Nm 3 , respectively, which are much higher than filterable PM 2.5 . K, Fe, Pb and Zn concentrations are high in filterable PM 2.5 for sintering process, which is attributed to the feedstocks of recycled materials. High sulfur content of the feedstocks results in high concentrations of SO 4 2-for all the test plants. In addition to Fe, the emissions of Pb, Zn and Sn are high for EAF, which is due to the complexity of the recycled steel feedstock for EAF. SO 4 2-is the highest emission ion for sinter process and coke making. For blast furnace, BOF and EAF, however, Na + , K + and Cl -are the predominated ions. For metal elements, concentrations of Na and K are highest for all the plants, which might be caused by their high potential of vaporization.

“…None of them afforded any information about the properties of PM 10/2.5 (particulate matters less than 10 μm/2.5 μm in aerodynamic diameter), which are generally more hazardous and has a high penetration to de-dust devices. 18) Others that provided the chemical profile and morphological features of PM 10/2.5 mainly focused on the particles sampled from the stack, [19][20][21] while the information about the properties of PM 10/2.5 generated throughout an integrated sintering process was still not found.…”
