“…Boiler slag had higher concentrations of Sn, Mo, Cr, Al, Pb, and Mn than fly ash, which, in turn, had higher concentrations of Ni, Hg, Cd, and Zn. The pH was lower at the boiler-slag than the flyash site (Podgaiski & Rodrigues, 2010).…”

“…Two sites are found in the area, of which one is a deposit of predominantly fly ash and the other of boiler slag (for details see Podgaiski & Rodrigues, 2010). Fly ash and boiler slag are aluminosilicate minerals, with the predominant components SiO 2 and Al 2 O 3 that differ in both physical and chemical properties (Rohde et al, 2006).…”

“…Consequently, this region has a number of sites exposed to long-term coal ash pollution (Teixeira et al, 1999). A recent research at one of these sites investigated the leaf decomposition of three abundant pioneer plants and the diversity of the associated soil invertebrate macrofauna and identified the terrestrial isopods as the most abundant soil macrofauna group in the leaflitter (Podgaiski & Rodrigues, 2010). In view thereof, this study focused on this terrestrial isopod community and investigated (1) the colonization patterns of different isopod species during the leaf decomposition of three pioneer plants and (2) the isopod abundance and reproductive traits at different coal residue deposits (fly ash and boiler slag).…”

The irregular disposal of coal combustion residues has adverse impacts on terrestrial ecosystems. Pioneer plants and soil invertebrates play an important role in the recovery of these areas. The goal of this study was to investigate the colonization patterns of terrestrial isopods (Oniscidea) in leaf litter of three spontaneous pioneer plants (grass -Poaceae, shrub -Euphorbiaceae, treeAnarcadiaceae) at sites used for fly ash or boiler slag disposal. The experiment consisted of eight blocks (four per disposal site) of 12 litter bags each (four per plant species) that were randomly removed after 6, 35, 70 or 140 days of field exposure. Three isopod species were found in the litter bags: Atlantoscia floridana (van Name, 1940) (Philosciidae; n = 116), Benthana taeniata Araujo & Buckup, 1994 (Philosciidae; n = 817) and Balloniscus sellowii (Brandt, 1833) (Balloniscidae; n = 48). The isopods colonized the three leaf-litter species equally during the exposure period. However, the pattern of leaf-litter colonization by these species suggests a conflict of objectives between high quality food and shelter availability. The occurrence of A. floridana and the abundance and fecundity of B. taeniata were influenced by the residue type, indicating that the isopods have different degrees of tolerance to the characteristics of the studied sites. Considering that terrestrial isopods are abundant detritivores and stimulate the humus-forming processes, it is suggested that they could have an indirect influence on the soil restoration of this area.Index terms: detritivores, coal residues, litter bags.(

“…To evaluate the activity of the epiedaphic fauna, three litter bags (WIEDER & LANG, 1982) were used per repetition. These were made of nylon, with dimensions of 30 × 20cm and a mesh of 10 × 8mm to allow the entry of soil micro, meso, and macrofauna (PODGAISKI & RODRIGUES, 2010). A green mass of ryegrass leaves equal to 10g of dry mass was packaged in each litter bag.…”
