“…The uptaken amount of heavy metals in soil and edible plant tissue exhibited higher level in sandy loam soil than clayey loam soil, implying that soil type plays important role in mobility, potential availability even uptaken ability to heavy metal by plant grown in amended soil (Bai et al, 2010;Brazauskiene et al, 2008;Singh and Agrawal, 2007). Results obtained by Li et al (2012) showed that level in the grain were found to be in the order of Zn > Cu > Cd, but for the straw the order was Cd > Cu > Zn, indicating different organs or tissues exhibited difference in bioconcentration factor for heavy metal. Bose and Bhattacharyya (2008) elaborated that the translocation amount from shoot to grain was found smaller than that of root to shoot of wheat, implying that heavy metal accumulation was proportionally lesser along with the elevation in plant height.…”

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.

“…However this practice possesses potential risks associated with contaminant accumulation in surface soils. Previous studies focus on the phytoavailability and toxicity of metals in soils extensively in order to conduct risk assessment of biosolids application (Li et al, 2012;McLaughlin et al, 2006). Besides metals, biosolids are known to contain significant levels of organic contaminants.…”

“…Initial field trials only focused on inorganic contaminants in the biosolid-amended soils (Li et al, 2012). Surface biosolid amended soil samples (0-20 cm) were collected on October 5, 2010 for the first time prior to the re-application of biosolid for analysis of organic contaminants in this study, and then once a month till October 2011.…”
