“…Namely, Lemly (1997), having reviewed environmental implications of selenium, pointed out that 'Rain can leach selenium from coal and oil-shale mining, preparation, and storage sites, where it may enter down-gradient streams and reservoirs through precipitation runoff'. Also, Dreher and Finkelman (1992) determined elevated concentrations (0.60-0.90 mg/L) of Se in the groundwater of a small backfill area at a surface mine; the authors interpreted it in the context of oxidation of selenium-bearing pyrite in the geological past, combined with mining operations which disturbed the overburden and altered its environment. Coleman et al (1993) emphasised that modes of occurrence of Se must be examined so as to assess its environmental impact.…”

“…Rybicka (1996) reviewed mining and metallurgical impact on the Polish environment, and proposed that "a combination of hydrological, chemical and/or geochemical investigations can provide much additional valuable information on concentrations of pollutants, e.g., trace metals, for the estimation of the environmental impact of mining and processing activities on rivers, groundwater and soils". Herewith, element measurements of biological, aquatic, airborne, and soil samples commonly give an insight into the effects of human activities such as fossil fuel combustion and mining on the environment (Adriano et al, 1980;Dreher and Finkelman, 1992;Kierczak et al, 2008;Dowarah et al, 2009;Csavina et al, 2012;Silva et al, 2012;Flues et al, 2013;Gomez-Gonzalez et al, 2014Oliveira et al, 2014;Saikia et al, 2015). Since the Labin City area has represented the major Croatian coal mining, metal industry, and coal-fired electricity centre for more than two centuries (Medunić et al, 2016a), the local aquatic as well as terrestrial environments could have been presumably exposed to mine and/or ash wastes, and airborne particles from former as well as recent stacks' emissions by multiple pathways.…”

“…Furthermore, the authors point out that Cd and Pb were found by previous studies to be correlated with human health problems due to coal combustion. Also, by referring to previously published papers, Dreher and Finkelman (1992) emphasise that excessive selenium has been identified as a cause of peridontal disease and dental caries in humans and as a possible carcinogen. Table 3 shows that slightly increased levels in herbal species were found for the following trace elements: Se in all three species, Sr in foliage, Cr in clover and mushroom, Cu in clover, and U in mushroom.…”

Abstract:The Labin City area has represented the major Croatian coal mining, metal industry and coal-fired electricity centre for more than two centuries. The domestic superhigh-organic-sulphur (SHOS) Raša coal is a unique variety compared to other coal types worldwide, based on its highest organic sulphur values, up to 11%. It was utilised in the Plomin coal-fired power plant during the period 1970-2000, and was replaced by an imported low-S coal afterwards. This paper presents the levels of S, Se, V, U, Hg, Sr, Cd, Cr, Pb, Cu and Zn in the two coal types, their bottom ash, seawater and plant (clover, mushroom and foliage) specimens collected from the Labin City area, while the sulphate was measured in surface stream water. Their levels were compared with relevant legislative as well as the published data from different world localities. Data analysis was interpreted in the context of past and recent coal combustion activities.

“…At SP-4-NA, dissolved organic and selenium concentrations were both very high. Dreher and Finkelman (1992), studying backfill wells at a mine near to Gillette, including some of the wells discussed in Naftz and Rice (1989), stated that because the selenium concentrations were decreasing, competition of organic acids for sorption sites is not a strong factor at those wells.…”

Recent Changes in the Geochemistry of the Reclaimed Porcupine Creek Alluvial Valley Floor, North Antelope/Rochelle Mine Campbell County, Wyoming

Abstract. Two sections of the Porcupine Creek alluvial valley floor have been reconstructed at Powder River Coal Company's North Antelope Rochelle Mine using specialized reclamation methods. The lower section of Porcupine Creek (AVF Reach 1) was re-constructed in 1985, but flow was bypassed by a diversion until early-2001. In addition, the lower creek was reconstructed using old channel design criteria that utilized a guide channel and limited the amount of pooled water. The lower reclaimed Porcupine Creek was constructed from native alluvium as required by the Wyoming Department of Environmental Quality / Land Quality Division (WDEQ/LQD) at the time.TDS and selenium concentrations in the alluvial monitoring wells in the lower reclaimed channel have been higher than in premining alluvial waters. The water quality reflected the new mobility of the constituents after mixing and oxidation of the highly mineralized alluvial material occurred during mining and aquifer construction. The alluvial water quality slowly improved between 1985 and 2001, but the future postmining water quality remained a concern. Following construction of pools and counter-weirs on AVF Reach 1 in early 2002 as part of a wetland establishment project, alluvial water levels have risen significantly. Boron concentrations spiked upward in the alluvial waters as water flushed through the vadose zone, but are now lower. Selenium concentrations are now much lower and geochemical conditions appear to be more reducing. The results of recent monitoring highlight the important geochemical processes ongoing in the aquifer and show that the construction of the pools and wetlands has improved the alluvial water quality in the AVF Reach 1. Further study of AVF Reach 1 is warranted as water quality in the reclaimed alluvium stabilizes. An upstream section of Porcupine Creek (AVF Reach 2) was reclaimed in 1999 primarily using selected overburden material as alluvium. TDS and selenium concentrations are much lower in AVF Reach 2.

“…The severity of potential Se toxicosis may vary. Studies conducted by Dheher and Finkelman (1992) showed that Se solubility is reduced with time in some surface coal mines. Continued monitoring of these areas appears warranted.…”

Absorption of Excess Selenium and Sulfur by Plants and Animals

High concentrations of selenium (Se) and sulfur (S) often occur in over-burden soils and underlying shales associated with western coal mining areas. Knowing the ·role of Se and S in the soil-plant-animal system is important for proper management of mine spoil reclamation. This paper will discuss recent findings about Se and S forms in soil, their absorption and accumulation by plants, and their subsequent toxicity to grazing animals. Selenium absorbed by the accumulating plants is generally metabolized to non-protein forms, while that absorbed by the non-accumulating plants occurs predominantly as selenomethionine. Selenomethionine is readily absorbed by animals. In animals, both acute and chronic forms of selenosis are known. Death occurs when a large dose of highly-available Se is ingested. One chronic form includes symptoms of inappetence, hair loss, hardening and extension of nails and hooves, reduced weight gains, and poor reproductive performance. Beath and Rosenfield identified "blind staggers" as another form of selenosis, but this disorder; more appropriately called polioencephalomalcia (PEM), occurred only in ruminants. However; the historical association of selenosis to blind staggers has been questioned. Recent experimental evidence has shown that PEM is likely caused by excess SO,. Cases of this disorder have been documented in the USA and Canada when ruminants have high S intake from herbage and/or drinking water. Western mine reclamation decisions should consider the potential for not only excess Se, but also excess SO 4 in water, soil, and plants.Additional
