“…A bottom-up approach was adopted to evaluate AHM emissions from China's industrial sources in 2010. The detailed process of emission inventory compilation has been elaborated and published by our previous research (Wu et al, 2018). In short, the AHM emissions in 2010 were calculated based on the sectoral activity level in 2010 and the integrate emission factors from the First China Pollution Source (FCPSC) database as shown in the following equation.…”

“…El Hg es un metal pesado volátil que se encuentra presente de manera natural en el suelo a bajas concentraciones (entre 0.01 y 0.2 mg/kg; Adriano 2001), pero su consumo en la MOAPE (1.0 a 2.0 g de Hg por gramo de oro producido) contribuye en gran medida al aumento de la concentración y circulación de este metal en la biosfera (Swain et al 2007). El Hg es un xenobiótico, porque todas sus formas químicas son exógenas al metabolismo de los seres vivos, y se encuentra catalogado conjuntamente con el plomo, cadmio, arsénico y cromo, como uno de los metales más tóxicos (Wu et al 2018). Ninguna de las formas químicas del Hg es inocua; una vez en el ambiente, el Hgº se oxida a Hg iónico, el cual se deposita eficientemente en el suelo y/o agua y es posteriormente convertido en metilmercurio (MeHg) por bacterias anaeróbicas (Le Jeune et al 2012).…”

Mercury (Hg) is the most harmful heavy metal for living beings due to its high toxicity, persistence, and bioaugmentation in the food web. Lantana camara has been considered promising for the phytoremediation of different metals, but its response to Hg has not been characterized. The objective of this study was to evaluate the effectiveness of L. camara to bioaccumulate, translocate, and volatilize Hg in artificially contaminated soils (1.0 and 8.0 mg/kg Hg). After two months of treatment, the dry weight was measured and the Hg present in stems, roots, leaves, and atmosphere was quantified using atomic absorption spectroscopy. The volatilized Hg was captured in hermetic chambers with continuous airflow, connected to a trap solution (5 % KMnO4 dissolved in H2SO4). The translocation factor was < 1, and the bioaccumulation factor was > 1 in both treatments. The Hgº values volatilized in high mercury indicate that approximately 7.1 µg/g plant/day can be released into the atmosphere. Our results indicate that L. camara accumulates Hg mainly in the root, showing potential for phytostabilization, but the observed volatilization rates point towards a more restricted use of this species in phytoremediation strategies.

“…High sulfate groundwater without treatment can cause equipment corrosion, soil acidification and crop wilting. Most research on high sulfate groundwater have focused on its removal, such as coagulant adsorbent, immersion ultra-filtration and packed bed anaerobic bioreactor (Wu et al 2018;O'Niell & Nzengung 2019), but did not understand its formation mechanism. To identify the formation mechanism can promote its treatment.…”

High sulfate mine groundwater at the Huaibei coalfield has exceeded the permissible limit (250 mg/l) of World Health Organization, posing serious threat to nearby water resource. A total of 28 samples were collected from Taiyuan formation aquifer (TA) and Ordovician aquifer (QA). In view of the mean concentration in two aquifers, the TA and OA were identified as high sulfate group and low sulfate group. The contrast on hydrochemical characterization and water-rock interactions were analyzed to reveal the mechanism of sulfate enrichment in mine groundwater. Compared with low sulfate groundwater, the high sulfate groundwater possess a higher content of TDS, Na+ and Cl−, which elevated by 3.83, 4.0 and 3.29 times, respectively. The low sulfate groundwater is controlled by Ca-Na-HCO3 type (82%), whereas the high sulfate groundwater is dominated by Na-SO4-HCO3 type (88%). The geochemical process of low sulfate groundwater is influenced by dissolution of carbonate minerals and weak ion exchange. The mechanism of sulfate enrichment in mine groundwater are predominately controlled by both silicate and carbonate minerals weathering, strong ion exchange interaction and competitive effect. The outcomes enhance understanding of the mechanism of high sulfate mine water and provide theoretical support for mine wastewater treatment.
