“…Because of the high affinity of organic compounds for Cu, the increase soil OM content encouraged the formation of stable organic complexes with Cu in compost treated soils. These results are similar observation of other researchers who have reported the application of composted sewage sludge increased Cu in organic fraction (Achiba et al, 2010;Mohamed et al, 2010).…”

“…Organic carbon (OC) content increased from 0.5 % in control to 2.5% after three successive years application 100 Mg ha -1 of compost. Increasing the soil organic carbon content improves soil physical characteristics, such as soil water retention and movement, soil structure and porosity, and favours the establishment of carbon cycling and also enhances fixation of toxic heavy metals in soils by the formation of insoluble organo-metallic complexes and therefore, it decreases their mobility and phyto-toxicity (Achiba et al, 2010;Zare et al, 2010). The application of compost significantly reduced soil bulk density and increased saturated hydraulic conductivity and aggregate stability percentage for all the treatments (Table 4).…”

A b s t r a c t. A 3-year field study was conducted to assess effects of composted municipal waste on some properties, distribution of Zn, Cu in a calcareous soil and uptake of these metals by wheat. The treatments were 0, 25, 50 and 100 Mg ha -1 of municipal solid waste which was applied in three consecutive years. The application of composted municipal waste increased the saturated hydraulic conductivity, the aggregate stability,the organic carbon content and electrical conductivity, whereas it slightly decreased the soil pH and bulk density. A significant increase in the concentration of Zn and Cu were observed with increasing number and rate of compost application. The distribution of Zn and Cu between the different fractions in untreated and treated soils showed that the majority of Zn and Cu were in the residual form. Finally, the levels of Zn and Cu were higher in grains of wheat grown in composttreated plots compared to that grown in the control plots.K e y w o r d s: composted municipal waste, fractionation, Zn, Cu, calcareous soil

“…Results obtained by Yeganeh et al (2010) showed that the Zn, Cu and Pb concentrations in soil run up to 1600, 7 and 4.5 times respectively relative to controls after being undergone four years amendment. Significant increase in total Cd, Cu, Pb and Zn concentrations in topsoil has been found after amendment of sludge for seven years (Ben Achiba et al, 2010;Egiarte et al, 2009) so that the risks posed by recycling of sludge to soil need to be further and cautiously assessed. Trace metal (Cu, Pb, Zn) concentration limits have found to be exceeded in soil receiving a certain amounts of sludge for one year (Florido et al, 2011).…”

a b s t r a c tRecycling sludge as a soil amendment has both positive and negative effects because of its enrichment in both nutrients and contaminants. So far, the negative effect has to be extensively investigated that the severities of different types of contaminants also remain unclear. The environmental behavior and risk of organic contaminant and pharmaceuticals, heavy metal and salt as well as pathogenic microorganisms brought by sludge amendment are summarized and discussed here. Organic contaminants and pharmaceuticals are typically found at low concentrations in sludge, the risks from sludge-amended soil decrease over time owing to its biodegradability. On the other hand, application of sludge generally increases soil salinity, which may cause physiological damage to plants grown in sludge-amended soil. In some extent, this negative effect can be alleviated by means of dilution; however, greater attention should be paid to long term increasing possible risk of eutrophication. Heavy metal (particularly of mobile heavy metals, such as Cd) with high concentrations in sludge and soil receiving considerable sludge can cause its incremental abundance in soil and crop contamination, further posing risks to humans, but most cases showed that there remained not excessive in heavy metal caused by sludge amendment. It is worth noting that increasing soil organic matter content may reduce transfer of heavy metal from soil to crops, but not restrict its uptake by crops at all. Combined literature together, it is summarized that heavy metal becomes a relatively severe bottleneck in recycling of sludge as soil amendment due to its nonbiodegradability and potential damage to health by adventuring contamination from agricultural products. Particular attention should therefore be paid to long term monitoring the change of heavy metals concentration in sludge amended soil.

Areas contaminated with metals may pose a serious risk to public health and the environment. At the end of the 1980s, an installment of temporary storage of hazardous industrial waste was available in the area of the Centro Tecnológico de Residuos (CENTRES), in the municipality of Queimados, state of Rio de Janeiro. Inadequate management of these wastes has had a major environmental impact on the soil in the region. So, in 2009, soils of this company were sampled to be evaluated the mobility, toxicity, bioavailability and environmental risk of Cd, Cr, Cu, Ni, Pb and Zn, sequentially extracting for the geochemistry fractionation (BCR) and metals determinated by ICP OES. The sum of all the geochemical fractions presented a sample P1 is severely contaminated by Zn, and which as P5 and P5.1 samples are contaminated by Cu, Ni, Pb and Zn, that a sample P5.2 is contaminated by Ni, Pb and Zn and that the sample P6 has Ni concentrations exceed the value of industrial research recommended by the Brazilian legislation. Generally, Cd, Ni and Zn are shown as the most mobile metals, due to the enrichment of their concentrations in the soluble and exchangeable fraction of the soil (F1). Pb was only found to be highly soluble and exchangeable in soil samples that were severely contaminated with this metal. On the other hand, Cu and Cr showed to be less mobile, preferring to be adsorbed to the oxidizable fraction of the soil (F3) or to the residue (R), which contains a silica matrix and high crystalline oxyhydroxides. Finally, the risk assessment code (RAC) proved to be a limited measure in overestimating the environmental risk of Cd and Ni and underestimating that of Cu. Keywords: Soil pollution; BCR and environmental risk assessment (RAC). ResumoÁreas contaminadas por metais podem configurar sério risco à saúde pública e ao meio ambiente. No final da década de 1980 foi instalado um pátio de estocagem provisória de resíduos industriais perigosos na área da empresa Centro Tecnológico de Resíduos (CENTRES), no município de Queimados, RJ. A gestão inadequada destes resíduos proporcionou um grande impacto ambiental ao solo da região. Então, em 2009 foram amostrados solos desta empresa para que fossem avaliadas a mobilidade, toxicidade, biodisponibilidade e risco ambiental de Cd, Cr, Cu, Ni, Pb e Zn utilizando extração sequencial para o fracionamento geoquímico (BCR), determinando-se as concentrações destes metais por ICP OES. A soma de todas as frações geoquímicas mostraram que a amostra P1 é severamente contaminada por Zn, que as amostras P5 e P5.1 são contaminadas por Cu, Ni, Pb e Zn, que a amostra P5.2 é contaminada por Ni, Pb e Zn e que a amostra P6 possui concentrações de Ni que ultrapassam o valor de investigação industrial preconizado pela legislação brasileira. Geralmente, o Cd, o Ni e o Zn se mostraram como os metais mais móveis, devido ao enriquecimento das suas concentrações na fração solúvel e trocável do solo (F1). O Pb só se mostrou altamente solúvel e trocável em amostras de solos que foram severamente cont...
