“…Leigong in subtropical southwestern China was reported to have distinctly increased with altitude (Zhang et al, 2013). In the Alpine Dimension Region of the Minya Konka (Mountain Gongga) on the Eastern Tibetan Plateau that is located far away from the industrial sources of emissions, Hg was found in elevated amounts in fruiting bodies of mushrooms (macrofungi) that have shallow mycelia and attains nutrients from leaf litter (Falandysz et al, 2014a).…”

“…Mercury, both as inorganic and metalorganic molecular forms (i.e., methylmercury, MeHg), accumulates in the food chain, while fungi are able to efficiently absorb this element from the soil substratum and accumulate in the flesh of the fruiting bodies. [1] Methylmercury is commonly known as the most environmentally relevant molecular form of Hg because of the high neurotoxicity of this compound. The MeHg is a persistent compound, which bounds firmly to the amino acid cysteine (MeHg-cysteine) in proteins.…”

This study aimed to examine the accumulation and distribution of total mercury (Hg) in fruiting bodies of edible wild-grown mushroom Hazel Bolete Leccinum griseum (Quél.) Singer, collected from six spatially distantly distributed places across Poland and to assess the probable dietary intake of the element by consumers. Mercury content of fungal and soil samples were determined by cold-vapour atomic absorption spectroscopy (CV-AAS) with a direct sample thermal decomposition coupled with gold wool trap of Hg and its further desorption and quantitative measurement at the wavelength of 296 nm. The median values of Hg content in caps of L. griseum collected from less-contaminated places (< 0.10 mg Hg kg(-1) dry matter in upper 0-10 cm layer of soil substratum) were from 0.23 mg kg(-1) dm to 0.43 mg kg(-1) dm. And for more contaminated topsoil (0.15 mg Hg kg(-1) dry matter), the median in caps was about 1.5 mg kg(-1) dry matter. The mushroom L. griseum has potential to accumulate Hg in fruiting bodies, while quantities of this element noted in consignments of this species originating from the forests with typical background values of Hg in topsoil are low. In the light of the published value of PTWI for Hg consumption of fruiting bodies of L. griseus emerged in forests of Poland is without health risk for consumers. Information on total mercury and methylmercury in Fungi of the genus Leccinum is also described briefly.

“…Once it reaches the ecosystems, Hg is distributed into the air, soil, water, and sediments, forming the largest metal deposits in the environment (Martinez-Finley and Aschner 2014). Elemental Hg is highly volatile and easily dispersed at the high temperatures that often occur at sites of amalgamation and subsequently undergoes global long-range atmospheric transport and deposition that allows its accumulation in biota, with subsequent human health risks (Falandysz et al 2014).…”

Background: Mercury (Hg) used in gold amalgamation is a major source of contamination in developing countries. The present study evaluates the concentrations of total mercury in water, sediment and fish from the Ankobra and Tano Rivers, which drain the major gold mining areas in Ghana. Total mercury (T-Hg) analysis was carried out using an atomic absorption spectroscopy (Perkin Elmer model 5100PC) equipped with a flow injection analysis system (FIAS, AS-90). Results:Water, sediment and fish T-Hg concentrations were 0.145-1.078 μg/L, 23.39-73.31, and 0.03-0.443 μg/g dw, respectively in Ankobra basin, while in Tano basin levels of 0.214-0.250 μg/L, 14.43-21.51, 0.068-0.413 μg/g were found for water, sediment and fish, respectively. The T-Hg concentration in water from both basins were within the World Health Organization threshold limits for drinking water except at River Asuo Kofi. Concentration of T-Hg in the sediment exceeded Environmental Protection Agency ecotoxicological threshold in some sampling stations, suggesting potential adverse ecological effects. T-Hg levels in fish from both basins were lower than the WHO value (<0.500 μg/g (wet wt). The target hazard quotient values, suggest that human should minimizing meals/week of the analyzed species to avoid deleterious effect during lifetime. Conclusions:The results suggested that mining activities significantly contribute to the considerable environmental Hg contamination in both Ankobra and Tano River basins. Therefore Hg levels should carefully monitored and controlled to reduce its inputs and mitigate potential health consequences of Hg accumulation in the environment.
