“…The mean concentrations of all five elements from these three sites followed the order YG > JLG > DZ ( Table 1), suggesting that both the operating and the abandoned Pb smelting facilities contributed to heavy metal(loid)s accumulation via atmospheric deposition. The concentrations of all elements at the DZ site (considered a control site in this study) were ∼3-2,500 times greater than the background soil elemental concentrations (Cheng et al, 2014) and were much greater than the heavy metal(loid)s concentrations from other studies (Jia et al, 2020;Liu et al, 2019). Given the distance of DZ from any industrial pollution source (∼25 km), element accumulation at this site was likely due to atmospheric resuspension and transportation/deposition of relatively small particles.…”

“…Depositional materials collected over time were also subjected to scanning electron microscopy-energy dispersal X-ray spectroscopy (SEM-EDS) to ascertain morphological and additional chemical composition information. Heavy metal(loid)s concentrations and the particulate matter depositional flux over time (Feng et al, 2019) may help elucidate whether surface-deposited heavy metal(loid)s from the abandoned and the operating Pb smelters contribute to particulate heavy metal(loid)s in local air.…”

Atmospheric deposition samples were collected over 15 mo at several locations near an operating smelter and an abandoned Pb smelter to investigate the contribution of Pb smelting to depositional fluxes and potential local air quality degradation. Samples were analyzed for As, Cd, Cu, Pb, and Zn and subjected to scanning electron microscopy (SEM)-energy dispersive spectroscopy (EDS). Concentrations of Cd and Pb at both sites were greater than at the control site (p < .05), and significant correlations existed between Cd and Pb concentrations at both sites (p < .05). Monthly depositional flux variations at both sites were similar, with greater deposition during cold and dry periods. Heavy metal(loid)s deposition during these periods was correlated with wind speed. Greater Cd depositional flux differences were found between the smelter and control sites compared with other elements. The SEM images suggested that some particles at the operating smelter site were from Pb smelting material. However, most particles at both sites had no characteristics of smelting, suggesting reactions occurred between the smelter-emitted particles and soil components. The EDS results indicated that atmospheric deposition from both sites had lower Pb concentrations than smelting material or ash. The main atmospheric deposition source at the operating and abandoned sites was likely from the resuspension of heavy metal(loid)-enriched soil particles. Greater risk of air pollution from historical Pb smelting facilities exists years after closing down. Reducing soil wind erosional losses may help reduce heavy metal(loid)s dispersion across environments. 1 INTRODUCTION Nonferrous metal mining and smelting are main sources of environmental heavy metal(loid)s pollution (Ettler,

“…Cement plants are frequently located in urban areas at high population density. However, the production of cement generates emission of particulate matter (Leone et al, 2016;Mohebbi and Baroutian 2007), gaseous pollutants (i.e., nitrogen oxides, sulfur oxides, carbon oxides (Lei et al, 2011)), heavy metals (Chen et al, 2010;Chen, 2020;Gupta et al, 2012;Liu et al, 2019;Wu, 2021), and persistent organic pollutants (i.e., polychlorinated dibenzo-p-dioxins and dibenzofurans, polychlorinated biphenyls Richards and Agranovski 2017;Zou et al, 2018)). Thus, the presence of cement plants has been linked with altered air quality in working areas (Noto et al, 2015) and in urban areas (Leone et al, 2016).…”

“…In particular, previous evidence points to cement production as a relevant contributor for the atmospheric emissions of several heavy metals as mercury (Chen et al, 2020;Wu et al, 2021), copper, arsenic, nickel, cadmium (Chen et al, 2010;Gupta et al, 2012;Liu et al, 2019), and chromium (Hwang et al, 2018;Isikli et al, 2003). Some of these metals have been identified as biomarkers of exposure deriving from cement production (Raffetti et al, 2019).…”

Cement plants located in urban areas can increase health risk. Although children are particularly vulnerable, biomonitoring studies are lacking. Toenail concentration of 24 metals was measured in 366 children (6-10 years), who live and attend school in a city hosting a cement plant. Living addresses and schools were geocoded and attributed to exposed or control areas, according to modeled ground concentrations of PM 10 generated by the cement plant. Air levels of PM 10 and NO 2 were monitored. PM 10 levels were higher in the exposed, than in the control area. The highest mean PM 10 concentration was recorded close to the cement plant. Conversely, the highest NO 2 concentration was in the control area, where vehicular traffic and home heating were the prevalent sources of pollutants. Exposed children had higher concentrations of Nickel (Ni), Cadmium (Cd), Mercury (Hg), and Arsenic (As) than controls. These concentrations correlated each other, indicating a common source. Toenail Barium (Ba) concentration was higher in the control-than in the exposed area. The location of the attended school was a predictor of Cd, Hg, Ni, Ba concentrations, after adjusting for confounders. In conclusion, children living and attending school in an urban area exposed to cement plant emissions show a chronic bioaccumulation of toxic metals, and a significant exposure to PM 10 pollution. Cement plants located in populous urban areas seem therefore harmful, and primary prevention policies to protect children health are needed.

“…Particulate matters (PM) are one of the components causing ambient air pollution. In general, PM were produced by human activity, such as chemical production and fossil fuel combustion [1,2]. PM are related to various diseases, including inflammations such as skin inflammation and lung inflammation, kidney diseases such as chronic kidney disease and end-stage renal disease, metabolic syndromes such as diabetes and obesity, as well as skin aging such as wrinkle formation [3][4][5][6][7][8][9][10][11].…”

Particulate matters (PM), the main contributor to air pollution, have become a serious issue that threatens human’s health. Skin is the largest organ in humans, as well as the primary organ exposed to PM. Overexposure of PM induces skin damage. Diphlorethohydroxycarmalol (DPHC), an algal polyphenol with the potential of skin protection, has been isolated from the edible brown seaweed Ishige okamurae. The purpose of the present study is to investigate the protective effect of DPHC against PM (ERM-CZ100)-induced skin damage in human dermal fibroblasts (HDF) cells. The results indicated that DPHC significantly and dose-dependently reduced intracellular reactive oxygen species generation in HDF cells. In addition, DPHC significantly induced collagen synthesis and inhibited collagenase activity in ERM-CZ100-stimulated HDF cells. Further study demonstrated that DPHC remarkably reduced the expression of human matrix metalloproteinases through regulation of nuclear factor kappa B, activator protein 1, and mitogen-activated protein kinases signaling pathways in ERM-CZ100-stimulated HDF cells. This study suggested that DPHC is a potential candidate to protect skins against PM-induced damage, and it could be used as an ingredient in pharmaceutical and cosmeceutical industries.
