Distribution and geochemical speciation of soil mercury in
The Wanshan Mercury Mine District (WMMD) is the largest historic Hg-producing district in China (Fig. 1). Long-term mining activities in WMMD have produced roughly 125.8 million tons of mine wastes, which are mainly consisted of the roasted calcines and gangue materials (Jiang et al., 2006). Mercury in mine waste has been mercury processing, preparation of the ore for use in various products.. Mercury (Hg) has a unique combination of physical properties.

Methylmercury Accumulation in Rice ACS Publications
Mercury is a global pollutant that can transform into methylmercury, a highly toxic and bioaccumulative organic form. Previous surveys have shown that fish is the main source of human methylmercury exposure, whereas most other food products have an average value below 20 µg/kg and primarily in the inorganic form.

Mercury (Hg) is a global pollutant and an acute neurotoxin (Lindqvist et al., 1991). As a unique heavy element that can exist in an elemental form (Hg 0), Hg exists largely as Hg 0 plus trace amounts of divalent gaseous Hg and particulate Hg in the atmosphere (Galbreath and Zygarlicke, 1996).

Environmental geochemistry studies in the area of Idrija mercury mine
Five centuries of mining and processing of mercury ore in the Idrija area have resulted in widespread contamination of different environmental compartments. Environmental impacts on a regional and local scale, caused by atmospheric emissions from the Idrija ore roasting plant, were established in the investigations of mercury spatial In this study, total mercury (THg) and methylmercury (MeHg) concentrations in muscles (leg and breast), organs (intestine, heart, stomach, liver) and blood were investigated for backyard chickens, ducks and geese of the Wanshan Mercury Mine, China. THg in poultry meat products range from 7.9 to 3917.1 ng/g, most of which Mercury risk in poultry in the Wanshan Mercury Mine, China

Spain, once a leading producer of mercury, mining at its centuries-old Almaden Mine stopped in 2003. In the United States, mercury occurrences are in Alaska, Arkansas, California, Nevada, and Texas. The declining consumption of mercury, except for small-scale gold mining, indicates that these resources are sufficient for centuries of use.In the Lanmuchang mercury mining area of China, the THg concentration in green cabbages (Brassica oleracea) has been shown to reach up to 18 mg kg −1. In the Wanshan mercury mining area of China, the THg concentration in rice samples has been recorded as between 4.9 and 215 μg kg −1 (dry weight).

Using mercury in small-scale mining stays a major threat
Exposure to mercury, even in small amounts, may cause serious health problems and is a threat to the development of the child in-utero and early in life. Mercury has toxic effects on the nervous, digestive, and immune systems, as well as on the lungs, kidneys, skin, and eyes. Mercury is considered by the WHO to be one of the top ten In the second half of the 20th century, fluorite mining made a significant visual impact on the whole area, whereas waste discharge from fluorite mineral processing in the zone reached the shoreline through rivers due to the absence of strict environmental controls ( Gutiérrez Claverol, 2009 ). 2.3.Contribution of fluorite mining waste to mercury contamination
