Cadmium from soil amended with sewage sludge: effects and residues in swine.
Liquid digested sewage sludge from a Chicago waste treatment plant was applied to experimental corn plots starting in 1968. The treatment plant received a high proportion of industrial effluent and the sludge averaged about 200 ppm Cd (dry weight). Corn grain harvested from the plots in 1974 was fed to growing swine for 56 days, and other swine were permitted to forage on the plots during the w...
متن کاملToxicologic studies with swine fed corn grown on municipal sewage sludge-amended soil.
Over a 3-yr period 336 MT/ha of dried sewage sludge, from a municipal waste treatment plant, was applied in liquid form to land subsequently used to grow corn. The sludge contained 115 mg Cd, 4,200 mg Zn and 538 mg Ni/kg dry matter and comprised the solids remaining after treatment of the waste waters of approximately 260 industries as well as domestic users. Corn grain harvested from the plot ...
متن کاملMicrobial activities in soil cultivated with corn and amended with sewage sludge
BACKGROUND One of the main concerns related to the increasing use of sewage sludge in the soil is the possible presence of excess nutrients, which could cause environmental problems and detrimental effects on the soil microorganisms, considered essential to soil nutrient cycling. Thus, the objective of this work was to evaluate the microbial biomass and activity and some chemical characteristic...
متن کاملCommunity Level Physiological Profiles (CLPP), Characterization and Microbial Activity of Soil Amended with Dairy Sewage Sludge
The aim of the present work was to assess the influence of organic amendment applications compared to mineral fertilization on soil microbial activity and functional diversity. The field experiment was set up on a soil classified as an Eutric Cambisol developed from loess (South-East Poland). Two doses of both dairy sewage sludge (20 Mg·ha(-1) and 26 Mg·ha(-1)) and of mineral fertilizers contai...
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 ...
