The Phytotoxicity Changes of Sewage Sludge-Amended Soils
The aim of the present study was the estimation of changes in the phytotoxicity of soils amended with sewage sludge with relation to Lepidium sativum, Sinapis alba and Sorghum saccharatum. The study was realised in the system of a plot experiment for a period of 29 months. Samples for analyses were taken at the beginning of the experiment, and then after 5, 17 and 29 months. Two kinds of sewage...
متن کاملMobility of heavy metals in soils amended with sewage sludge
Morera, M. T., Echeverría, J. C. and Garrido, J. J. 2001. Mobility of heavy metals in soils amended with sewage sludge. Can. J. Soil Sci. 81: 405–414. Sewage sludges added to arable land can improve soil fertility and physical properties. However, the concentrations of heavy metals commonly found in sludges limits their application to soil. The purpose of this paper is to evaluate the mobility ...
متن کاملBioavailability of heavy metals in soils amended with sewage sludge
Morera, M. T., Echeverría J. and Garrido, J. 2002. Bioavailability of heavy metals in soils amended with sewage sludge. Can. J. Soil Sci. 82: 433–438. The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and Zn applied to soils in urban...
متن کاملImpact of sewage sludge conditioning and dewatering on the fate of nonylphenol in sludge-amended soils.
The fate of (14)C-labelled p353-nonylphenol (NP) in soils amended with differently treated sludges originating from the same precursor sludge was assessed. The effects of commonly applied conditioning and dewatering techniques were investigated. Nonylphenol was degraded considerably faster in soils amended with liquid sludge, while a significant portion of it remained intact and extractable by ...
متن کاملInfluence of Dissolved Organic Matter on the Solubility of Heavy Metals in Sewage-Sludge-Amended Soils
Sewage-sludge-amended soils generally contain elevated levels of organic matter and heavy metals compared to control soils. Because organic matter is known to complex with heavy metals, the solubility behavior of the organic matter in such soils may exert a significant influence on the solubility of the metals. Little is known about such a process. Using batch experiments in which the solubilit...
