“…However, total metal(loid)s concentration in fly ash, such as As, B, Cd, Cr, Co, Cu, Mn, Mo, Ni, Pb, Se can be toxic and can vary depending on coal, combustion conditions, operating parameters, transport system, leaching processes, effects on plants, and climatic conditions (Adriano et al, 1980;Haynes, 2009). Over time, proportion of total sand in fly ash is reduced (83.3-71.6%, Gajić et al, 2016) and the clay fraction is increased (1.2-2.5%, Gajić et al, 2016) whereas the percentage of hygroscopic water is increased (0.56-2.3%, Gajić et al, 2016) and this all together provides good aggregation and capillarity (DŽeletović and Filipović, 1995;Gajić et al, 2016). In weathering fly ash, EC values (101.4 µS/cm, 0.217-0.190 dS/m, Gajić et al, 2016) and pH decreased (7.95-7.87, Gajić et al, 2016;8.85, Pandey and Singh, 2014), content of organic carbon (1.85-1.13%, Gajić et al, 2016;2.05%, Jambhulkar and Juwarkar, 2009) and total nitrogen (0.06-0.11%%, Gajić et al, 2016;0.05% Pandey and Singh, 2014) as well as the available content of K 2 O and P 2 O 5 increased (52.5 mg/100 g and 10.1 mg/100 g, Gajić et al, 2016;38.2-59.5 mg/100 g, 25.3 mg/100 g, Kostić et al, 2018).…”

“…Unweathered fly ash fly ash and mine spoil, prevent wind erosion, decrease mobility, toxicity, and dispersion of chemical elements in the surrounding environment, provide the organic substance which can bind contaminants and reduce transfer of pollutants in the food web (DŽeletović and Filipović, 1995;Pavlović et al, 2004;Djurdjević et al, 2006;Mitrović et al, 2008;DŽeletović et al, 2009;Haynes, 2009;Pandey, 2012;Maiti, 2013;Pandey et al, 2015aPandey et al, ,b, 2016aGajić et al, 2016). Therefore, ecorestoration of degraded sites is the process of renewing ecosystem stability and resilience after stress or disturbance with respect to its health, integrity and sustainability (SER, 2002) presenting a key issue in environmental science and ecological engineering.…”

Fly ash generates as the result of coal combustion in thermoelectric power stations whereas ore mining activities produce mine waste-rock and tailings worldwide. High concentrations of metal(loid)s and organic pollutants in fly ash and mine wastes are released into soil, air, and water presenting a global threat to the surrounding environment and human health. The environmentally sound management of fly ash and mine wasterock and tailings includes monitoring stability of the dam construction and seepage flowrate, prevention of water erosion and dust spreading, reducing the footprint of the management facilities and successful restoration/revegetation. Harsh conditions prevailing on fly ash and mine deposits are unfavorable mechanical composition and pH, high concentrations of soluble salts, lack of nitrogen and phosphorous, reduced number of microorganisms and fungus, toxic concentrations of As, Au, Ag, B, Cu, Cd, Cr, Hg, Mn, Mo, Ni, Pb, Zn, and the presence of PAHs and PCBs. The review addresses phystostabilization, phytoextraction, rhizodegradation, and phytodegradation as main phytoremediation green technologies which use plants to clean up the contaminated area to safe levels. Establishment of the self-sustaining vegetative cover on fly ash and mine deposits is crucial for recovering ecosystem health, stability, and resilience. Therefore, here we have discussed the essential role of native plants in the ecorestoration process on waste deposits. Additional emphasis is given to the evaluation of plant adaptive response to pollution stress. This review presents a current knowledge in phytomanagement of fly ash deposits, mine waste-rock and tailings. Also, it provides a new frontier in restoration physiology where physiological and biochemical tools can be used to predict plant response to stressors and success of restoration projects.

“…Improving both physical and chemical properties appears crucial as the application of realistic quantities of inorganic fertilizer alone generally is not sufficient due to the immobilization of fertilizers' NPK in the receiving CCRs (Insam and Stalljann, 1989; Mulhern et al, 1989; Van Rensburg et al, 1998). Positive growth responses to inorganic fertilization have been reported only at application rates >480 kg ha −1 (Dzeletovic and Filipovic, 1995; Van Rensburg et al, 1998). The use of biosolids as an alternative to mineral fertilizers is potentially paralleled by a mobilization of As and Se (Jackson and Miller, 2000).…”

Disposal of Coal Combustion Residues in Terrestrial Systems: Contamination and Risk Management

et al. 2010

The world's ever-growing energy demand will lead to the installation of new coal-fired power plants. At least part of the coal combustion residue (CCR) generated in the coming years will be disposed of, adding to the large number of CCR disposal sites generated in the past and reinforcing the need for sound assessment and management of associated risks. Physical and chemical composition of CCR varies considerably depending on the quality of the feed coal, the combustion technology, fraction considered, and the method of disposal. Related risk pathways include (i) aerial routes, i.e., dust resuspension (Cr(VI)), emanation of radioactivity (Rn associated with U and Th series), and Hg volatilization threatening animal and human health; (ii) phytoaccumulation (B, Se, Mo, As) and plant toxicity (B) with subsequent effects on animals (e.g., Mo-induced hypocuprosis, As and Se toxicity) and humans (e.g., selenosis; food chain); and (iii) effluent discharge and percolation to groundwater and rivers (suspended solids, unfavorable pH, high Se, B, Hg, and As(III) concentrations). Recent and projected changes of CCR composition due to emerging clean coal technologies require close monitoring as the concentration of volatile elements such as Hg and Se, solubility (Hg, Cd, Cu) and volatilization (Hg, NH(3)) of some pollutants are likely to increase because of higher retention in certain fractions of CCRs and concurrent changes in pH (e.g., by mineral carbonation) and NH(3) content. These changes require additional research efforts to explore the implications for CCR quality, use, and management of risk associated with disposal sites.

“…Radi sprečavanja raznošenja pepela vrši se biološka rekultivacija površina odlagališta setvom trava na nasipima aktivnih i pasivnih kaseta, kao i setvom na ravnim delovima pasivnih kaseta, uz sadnju različitih vrsta drveća i žbunova. Iako je reč o hroničnom i sinergističkom delovanju stresnih faktora (vodni deficit, nepovoljne fizičke i hemijske karakteristike pepela, teški metali u višku) na pepelištu, veliki broj različitih vrsta biljaka toleriše oštre ekološke uslove, i sa manje ili više teškoća opstaje i širi se na pepelu [1,2]. Pepeo ima veliku sposobnost infiltracije vode i u letnjim mesecima ne zadržava vlagu, tako da se biljke moraju prilagoditi sušnom okruženju i generalno slabije napreduju nego u prirodnom okruženju, pa se vrši plansko navodnjavanje.…”

Sam proces setve zbog toga zahteva unošenje velikih količina semena trava i pojačano đubrenje sa većim normama azota u odnosu na klasičan pristup u poljoprivredi [1]. Rekultivacija je često diktirana i dostupnošću semenskog materijala specifičnih višegodišnjih travnih vrsta, otpornih na ekstremne agroekološke prilike odlagališta pepela.…”

Pet krmnih trava, ježevica (Dactylis glomerata L.), francuski ljulj (Arrhenatherum elatius Presl.), italijanski ljulj (Lolium multiflorum Lam.), crveni vijuk (Festuca rubra L.) i visoki vijuk (Festuca arundinacea Schreb.) su ispitivane na nezagađenom njivskom zemljištu na oglednom dobru "Radmilovac" u Beogradu, i na odlagalištu pepela termoelektrane "Nikola Tesla A" (TENT A) u Obrenovcu. Merene su koncentracije As, Pb, Cd, Zn, Ni, Fe i Cu u zemljištu i pepelu, kao i u tkivima ispitivanih vrsta trava u cilju utvrđivanja zdravstvene bezbednosti u ishrani domaćih životinja. Uzorci trava su prikupljani u fazi klasanja, u punom vegetativnom razvoju. Skidana je nadzemna biomasa u 3 ponavljanja na visini od 3-5 cm, oponašajući ispašu ili kosidbu. Analiza je pokazala visok sadržaj As i Ni u pepelu dok je sadržaj svih elemenata u zemljištu bio u dozvoljenim koncentracijama. Koncentracije As, Cd, Fe i Ni su bile više u travama sa pepelišta, koncentracije Pb i Cu u travama sa njivskog zemljišta, dok su koncentracije Zn bile slične u uzorcima sa oba lokaliteta. Rezultati ispitivanja ukazuju da krma trava sa obe lokacije ne akumulira metale iznad tolerantnog nivoa za ishranu goveda, ali da se mora oprezno pristupiti mogućnosti korišćenja trava sa pepelišta za krmu.
