“…As a probable consequence of the alkaline substrate, Cu:Mo ratios in the same plant species were below values reported to cause chronic toxicity symptoms in ruminants. Weinstein et al (1989) and Woodbury et al (1999) found Mo concentrations of up to 28.9 mg kg −1 in sweet clover and 18.7 mg kg −1 in bird's foot trefoil ( Lotus corniculatus ), respectively. In both cases, concentrations exceeded values indicating toxicity to animals (Adriano, 2001).…”

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.

“…Addition of CFA up to 8% in acidic soils increased yield of several agronomics crops ). CFA addition to soils has increased crop yield of alfalfa (Medicago sativa), barley (Hordeum vulgare), Bermuda grass (Cynodon dactylon), and white clover (Trifolium repens) and improved the physical and chemical characteristics of the soil Weinstein et al 1989). In a previous study, it was reported that mixed application of CFA and paper factory sludge caused appreciable change in soil physical and chemical properties, increased pH, and increased rice (Oryza sativa) crop yield (Hill and Lamp 1980;Molliner and Street 1982).…”

Plants grown on coal fly ash landfills can accumulate relatively high concentrations of selenium (Se), which may be ameliorated with gypsum application to the soil. In 1988 and 1989, experiments were conducted to measure the accumulation of Se in forbs and grasses growing on a coal fly ash landfill. In 1990, a dose-response study was conducted to determine whether forbs and grasses growing on a fly ash landfill would respond to gypsum applications with reduced tissue levels of Se and increased levels of S. Higher concentrations of Se were found in plants grown on the landfill than on nonlandfill control plots, and leguminous species tended to accumulate more Se than nonlegumes. Two of the four studied species-bird's-foot trefoil (Lotus corniculatus L.) and bitterweed (Picris hieracioides L.)-had higher concentrations of S when grown with gypsum. However, only bird's-foot trefoil showed significantly reduced Se. The difference in tissue levels of Se and S was a presence/absence response, not a monotonic response to the rate of applied gypsum. Although it is clear that gypsum applications have the potential for mitigating Se uptake by some plants, the response is quite variable on a fly ash landfill, probably due to variability in concentration and availability of Se in the soil cap.
