“…Cinnabar is a toxic mineral, which becomes more toxic when subjected to thermal processes above 300°C because highly toxic gases of Hg 0 and SO 2 are released (Williams et al 1999;Berglund et al 2005;Liu et al 2008Liu et al , 2018Wei et al 2008;Sherman et al 2013;Wang et al 2015). The ability to characterize this metallic element isotopically opens up the possibility of tracking its geological source and following its dispersion during mining, metallurgy and/or contamination (Williams et al 1999;Berglund et al 2005;Llanos et al 2011;Sherman et al 2013;Balland-Bolou-Bi et al 2017). Its physical and chemical characteristics (e.g., bright red colour, low melting point) made this chromophore attractive to ancient populations and thus important to archaeological studies.…”

Toxic Pigment in aCapacochaBurial: Instrumental Identification of Cinnabar in Inca Human Remains from Iquique, Chile

We report on the analysis of a red pigment found in a lavish Inca burial from Cerro Esmeralda, Chile, associated with the human sacrifice of two young girls. The outcome shows that the red pigment is mainly cinnabar, with 95% of HgS content. Cinnabar is rarely found in the archaeological record of Chile. Thus, we propose that our results are another line of evidence supporting Iquique's Cerro Esmeralda inhumation as a unique Inca ritual. It was a special lower‐elevation capacocha burial, most probably undertaken to politically and symbolically incorporate the coastal people into the Tawantinsuyo Empire.

“…Metal mercury complexes, or certain amalgams, are considered to be less toxic because they are more difficult to mobilize without specific reactions, such as chemical or microbial reduction. The least toxic forms of mercury, such as mercuric sulphide or cinnabar (HgS) [14,15], are generally stable in soils, but may be weathered by simple dissolution in acidic environments [15] by significant root exudates such as those from fabaceae [16] or by microbial production of low molecular weight organic acid (LMMOAs) [17]. Determining mercury speciation at anthropized sites such as former mining sites is therefore very important for assessing the positive or negative health impact of ecological rehabilitation [15].…”

As rehabilitation efforts in Guyana are recent, there is little information on the effect of different ecological rehabilitation protocols for Guyana’s mining sites on biogeochemical cycles and mercury mobility. This study was conducted to assess the impact of different ecological restoration protocols on soil quality with the use of soil microbial indicators and by estimating the mercury mobility. We sampled soil from six rehabilitated mining sites in French Guyana with different ecological restoration procedures. We carried out measurements of enzymatic activities and an analysis of mercury environmental speciation to assess its potential toxicity according to a mobility gradient. The results obtained in this study show that the rehabilitation of mining sites has been carried out in a heterogeneous manner and soil quality is very variable, even in nearby sites. Sites that have been rehabilitated with fabaceous species have positive soil quality indicators. In addition, the results highlight a change in mercury mobility that is 82.1% correlated after co-inertia analysis with soil texture properties, which also confirms a direct effect of rehabilitation on mercury mobility. The non-restored sites had a much higher potential of mercury mobility and toxicity than the sites where ecological restoration was successful. These results highlight the positive effect of controlled rehabilitation and ecological restoration on microbiological activities and the potential toxicity of mercury.

“…Various studies have suggested that dissolved organic matter (Ravichandran et al 1998 ; Waples et al 2005 ; Miller et al 2009 ), oxidant conditions (Holley et al 2007 ), microbial activity under oxic and anoxic conditions (Barkay and Wagner-Döbler 2005 ; Balland-Bolou-Bi et al 2017 ), pH, and high-water concentrations of Fe 3+ and sulphur chemical species, such as HS − and S 0 (Jay et al 2000 ), are the major factors regulating the dissolution of cinnabar and metacinnabar (HgS). The dissolution of these Hg sulphides usually occurs by oxidation of sulphur (S 2− ), forming elemental Hg 0 and Hg 2+ water soluble species in relation to pH, redox conditions, and concentrations of ligands.…”

New geochemical data for defining origin and distribution of mercury in groundwater of a coastal area in southern Tuscany (Italy)

A geochemical study was conducted in a coastal plain in the Orbetello Lagoon area in southern Tuscany (Italy), acquiring new data on groundwater, lagoon water, and stream sediment for insights into the origin, distribution, and behaviour of mercury in a Hg-enriched carbonate aquifer. The main hydrochemical features of the groundwater are ruled by the mixing of Ca–SO4 and Ca–Cl continental fresh waters of the carbonate aquifer and Na–Cl saline waters of the Tyrrhenian Sea and Lagoon of Orbetello. Groundwater had highly variable Hg concentrations (< 0.1–11 μg/L) that were not correlated with the percentage of saline water, depth in the aquifer, or distance from the lagoon. This excluded the possibility that saline water could be the direct source of Hg in groundwater and responsible for release of the element through interaction with the carbonate lithologies of the aquifer. The origin of Hg in groundwater could be ascribed to the Quaternary continental sediments overlying the carbonate aquifer because i) high Hg concentrations were found in the continental sediments of the coastal plain and in the contiguous lagoon sediments; ii) waters from the upper part of aquifer had the highest Hg concentrations; iii) Hg levels in groundwater increased with increasing thickness of the continental deposits. The high Hg content in the continental and lagoon sediments is geogenic due to regional and local Hg anomalies and to sedimentary and pedogenetic processes. It can be assumed that i) water circulating in these sediments dissolves the solid Hg-bearing constituents and mobilises this element mainly as chloride complexes; ii) Hg-enriched water moves from the upper part of the carbonate aquifer due to the cone of depression generated by intense pumping of groundwater by fish farms in the study area.
