“…To estimate mercury mass balance in CETEPEC it was necessary to consider the mercury concentration in coal (0.335 mg/kg), mercury concentration in bottom ash and slag (0.148 mg/kg), and mercury concentration in fly ash (0.017 mg/kg), all of them analyzed by Fuentes et al (2017). CETEPEC consumed 5 832 666 t of coal in 2013, 10 % (583 266 t) corresponding to bottom ash and slag, and fly ash.…”

“…Considering how toxic and persistent is the presence of mercury in the atmosphere, Sosa et al (2014Sosa et al ( , 2017 investigated the mercury emissions from 2012 to 2013 using monthly coal consumption data provided directly by the industrial sector for the three Mexican coal-fired power plants, and Fuentes et al (2017) reported the spatiotemporal variability of atmospheric mercury using per-day and per-generatingunit data of one coal-fired power plant (CETEPEC) in Mexico. Fuentes et al (2017) reported that mercury concentration in the coal from a Kansas mine in the USA, which is used by CETEPEC, was 0.335 mg Hg/kg of coal, and Múgica et al (2003) reported a concentration of 0.333 mg Hg/kg in Mexican coal. Table I shows the mercury emissions from coalfired power plants by country.…”

“…Investigation shown that Hg pollution areas match well with the location of the expressway, peri-urban, rural settlement and quarries. Previous studies reveal that Hg concentrations in surface soils are mainly attributed atmospheric deposition [60][61][62][63]. The results of the air pollution monitor show that the concentration of Hg is relatively high in heavily polluted areas (Unpublished data).…”

With the rapid industrialization and urbanization, more attention is turning to heavy metal contamination in the soil environment. To assess the potential environmental risk on soil, a comprehensive geochemistry study on heavy metal was performed in Laizhou, eastern China, using 3834 surface soil samples (0–20 cm, regular grid of 1 × 1 km2) and 60 layered soil samples (0–200 cm) were analyzed. The average concentrations of As, Cd, Cr, Cu, Hg, Ni, Zn and Pb were 7.60 mg·kg−1, 0.15 mg·kg−1, 45.50 mg·kg−1, 19.10 mg·kg−1, 44.00μg·kg−1, 18.70 mg·kg−1, 51.40 mg·kg−1 and 29.00 mg·kg−1, which were lower than the threshold levels of the Grade II criteria of China national environment quality standard for soil, but the contents of As, Cd, Hg, and Pb were higher than background values of eastern Shandong Province surface soil. Fractionation analysis showed that the potential bioavailability in surface soils decreases in the order of Cd > As > Cu > Ni > Zn > Cr > Pb > Hg. Soil assessments with enrichment factor, contamination factor, Nemerow composite index, geo-accumulation index and potential ecological risk index, indicate the soil in Laizhou is contaminated strongly with As, Cd and Hg and a moderately Cr, Ni, Cu and Zn. The level of Pb pollution is between moderate to high. Multivariate analyses suggest that Cr and Ni were derived mainly from natural sources, and As, Cd, Pb, while Hg mostly came from anthropogenic sources. Cu and Zn were from a mixture of anthropogenic and natural sources. Our results demonstrate that more attention should be paid to monitoring soil quality in the heavily polluted site.

“…Natural sources include volcanoes, geothermal activity, geological deposits of Hg minerals and re-emission of Hg previously deposited from air onto the surface of soil and water, whereas anthropogenic sources derive from mining (both for Hg and for other minerals) and extraction and burning of fossil fuels, which contain Hg as a trace contaminant (primarily coal), as well as production of metals, alkalis, cement and waste incineration [ 7 , 8 ]. Among industrial activities, GEM emission is prevalent especially at mining sites [ 9 , 10 , 11 , 12 ] and chlor-alkali plants using Hg-cell technology [ 13 , 14 , 15 ], but also in other Hg-related factories [ 16 , 17 , 18 ]. The atmosphere is the central pathway of dispersion for Hg emissions.…”

We present the first assessment of atmospheric pollution by mercury (Hg) in an industrialized area located in the Ossola Valley (Italian Central Alps), in close proximity to the Toce River. The study area suffers from a level of Hg contamination due to a Hg cell chlor-alkali plant operating from 1915 to the end of 2017. We measured gaseous elemental Hg (GEM) levels by means of a portable Hg analyzer during car surveys between autumn 2018 and summer 2020. Moreover, we assessed the long-term dispersion pattern of atmospheric Hg by analyzing the total Hg concentration in samples of lichens collected in the Ossola Valley. High values of GEM concentrations (1112 ng m−3) up to three orders of magnitude higher than the typical terrestrial background concentration in the northern hemisphere were measured in the proximity of the chlor-alkali plant. Hg concentrations in lichens ranged from 142 ng g−1 at sampling sites located north of the chlor-alkali plant to 624 ng g−1 in lichens collected south of the chlor-alkali plant. A north-south gradient of Hg accumulation in lichens along the Ossola Valley channel was observed, highlighting that the area located south of the chlor-alkali plant is more exposed to the dispersion of Hg emitted into the atmosphere from the industrial site. Long-term studies on Hg emission and dispersion in the Ossola Valley are needed to better assess potential impact on ecosystems and human health.
