“…Earlier studies reported that M. procera has the ability to efficiently bioconcentrate Hg [54][55][56][57]. This species, apart from being rich in the essential elements (including Cu and Zn), is also rich in Cd, Pb, Hg, and Ag [2,14,26,40,56].…”

“…Typical examples of this are Al, Ca, or Fe [12]. Cadmium, chromium, mercury, lead, copper, and zinc are the heavy metals most frequently studied in wild mushrooms [40][41][42][43][44][45]. There is scarcity of data on mineral composition of the same mushroom species that emerged at geographically distant places that have different soil bedrock geochemistry and environment [46][47][48].…”

Fungi play a key role in the transfer of metals from the lithosphere into the biosphere. Within the biodiverse world, mushrooms are the important groups that constitute edible and medicinal mushrooms. Most of the estimated 2,000 species of edible wild mushrooms that grow worldwide are poorly characterized with respect to their composition and multi-mineral constituents as well as their bio-accessibility, while such information is completely absent for numerous species. In the studies of metallic elements and metalloids in mushrooms, the pertinent question is the unraveling of the qualitative and quantitative interrelationships between the elements/ Pol. J. Environ. Stud. Vol. 25, No. 6 (2016), 2445-2460 Original Research AbstractThis paper presents analytical and scientific monitoring data on the bioconcentration potential of trace elements and mineral compounds in Macrolepiota procera collected from background areas in upland regions of central Poland. The contents of Ag, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Pb, Rb, Sr, and Zn in caps and stipes (99 specimens) and underlying soil substrates were examined by ICP-OES and Hg by CV-AAS after wet digestion. The results showed that M. procera is a rich source of especially Ca, Cu, Fe, K, Mg, Mn, Na, and Zn. The contents of Pb, Hg, Ag, and Cd in the caps were 1.7±0.6 to 5.9±1.7, 1.8±0.8 to 5.3±0.8, 1.2±0.7 to 16±7, and 0.56±0.13 to 4.9±5.4 mg kg -1 dry matter, respectively. Probable dietary intake assessment showed that occasional consumption (once a week) of Macrolepiota procera caps could be safe, while consumption more than once a week could provide doses of toxic metals that exceed the provisionally allowed daily intake limits for humans.

Heavy metals constitute one of the most important environmental problems. They can be transported in an environment in various forms: emitted into the atmosphere they are carried over long distances, accumulate in soil, sediments and organisms by bioaccumulation, and the biomagnification processes in the trophic chain [1]. Deposition of trace elements and heavy metals in vegetables [2] and mushrooms [3][4][5][6] to a large extent already has been proven, especially in areas potentially contaminated or located in the zone of pollutants, such as power plants, waste dumpsites, metal smelters, and chemical plants [7].Due to the fact that overgrowing topsoil long-lived mycelium can retrieve with water significant amounts of trace elements and pass them to the fruiting bodies of macrofungi [8], there is a risk of bioaccumulation of detrimental elements in organisms of potential consumerswild forest animals, such as roe deer, red deer, wild boars [9], as well as people. The international surveys revealed that macrofungi are able to accumulate in their fruiting bodies a large amounts of cadmium, lead, mercury, zinc, copper, manganese, iron, chromium, silver, and nickel absorbed from contaminated soil [3][4][5][6][10][11][12].The purpose of this study was to determine the level of heavy metals (Pb and Hg) and trace element (Zn, Mn, Cu, and Fe) concentrations in fruiting bodies of 8 species of macrofungi, and to indicate the bioaccumulation factors of elements from soil substrate to fruiting bodies.Pol. J. Environ. Stud. Vol. 24, No. 2 (2015), [651][652][653][654][655][656] Materials and MethodsMushroom and soil samples were collected in October 2010 from Wkrzanska Forest adjacent to Nowe Warpno in the West-Pomeranian voivodeship of north-western Poland (Fig. 1). The main branch of industry in the sampling area is fisheries, thus the forest environment is potentially unpolluted. Macrofungi and soil substrate samples were collected from dry coniferous forest, characteristic for this region. The forest was a monoculture of Pinus sylvestris with a few other species occurring only in undergrowth, like juniper and maple.Generally, 25 samples (each comprising 2-5 fruiting bodies) of eight mushroom species with underneath fruiting bodies soil samples were collected. The examined species were edible Boletus badius (Fr.) Fr. The fruiting bodies were cleaned from any debris, divided into cap and stalk, and then dried in a laboratory oven with a temperature up to 40ºC. Dried samples were homogenized using a laboratory mill. Simultaneously, soil samples were air-dried for several days, sieved with 1 mm pore sieve, and then pulverized using a mortar.Digestion of mushroom samples (0.5 g) was performed with a cold oxi-acidic mixture of 65% HNO 3 and perhydrol (4 and 1 mL, respectively) for at least 12 hours and then put in a MilestoneTM microwave oven. Digestion of soil samples (0.5 g) was conducted using 6 mL of a 5:1 concentrated HNO 3 :HClO 4 (65:60%) mixture and 1 mL of perhydrol and also mineralized in the microwave oven. Mineral...

“…Regarding soil, the most important for contamination by both the radioactive cesium and toxic metals is the organic soil layer. Therefore, only concentrations and activity measured in the organic layer are used for the calculations [14][15][16][17][18][19][20][21][22][23][24].…”

Tightening of norms for air protection leads to a development of new and significantly more effective techniques for removing particulate matter, SOx and NOx from flue gas which originates from large solid fuel combustion. Recently, it has been found that combinations of these environmental technologies can also lead to the reduction of mercury emissions from coal power plants. Now the greatest attention is paid especially to the coal power plant in Opatovice nad Labem, close to Hradec Kralove. Its system for flue gas dedusting was replaced by a modern type of cloth fabric filter with the highest particle separation efficiency which belongs to the category of BAT. Using this technology, together with modernization of the desulphurisation device and increasing of nitrogen oxides removal efficiency, leads also to a reduction of mercury emissions from this power plant. The University of Hradec Kralove, the Opole University and EMPLA Hradec Kralove successfully cooperate in the field of toxic metals biomonitoring almost 20 years. In the Czech-Polish border region, comprehensive biomonitoring of mercury in bioindicators Xerocomus badius in 9 long-term monitored reference points is done. The values of mercury concentration measured in 2012 and 2016 were compared with values computed by a dispersion model SYMOS´97 (updated 2014). Thanks to modern methods of dedusting and desulphurisation, emissions of mercury from this large coal power plant are now smaller than before and that the downward trends continues. The results indicate that Xerocomus badius is a suitable bioindicator for a long-term monitoring of changes in mercury imissions in this forested border region. This finding is significant because it shows that this region is suitable for leisure, recreation, and rehabilitation.
