“…Interpolating the extraction degrees, achieved by acidified electrolyte solutions at pH 2.0 and 5.0, proton-induced metal solubilization seems to be of minor importance except for Cd and Zn. Extraction tests performed with an amino acid mixture, composed analogously to the amino acid fraction of the GS effluent, demonstrated that these components enhanced the solubilization of Cu only (20). This agrees with earlier findings of low leaching performances of glycine, L-histidine, L-cysteine, and Dpenicillamine at pH e5.0 (26,27).…”

“…The leaching efficiency of the GS effluent at pH 4.4 is governed by its main component, lactic acid (20). At the given pH, which is about a half unit above the pKa value of this compound, lactic acid acts as a proton-delivering and complexing agent.…”

“…Typical for this group are silage effluents released in large amounts during silaging of crops, for example, in cattle breeding farms. Effluents from grass silage (GS) and clover silage (CS) were sampled from Lower Bavarian farms (20). Group B comprises solid residues marked by high contents of proteins or peptides.…”

The utilization of biomass residues as sources for natural chelates is a new approach to improve the ecological and economical balance of leaching techniques for the remediation of metal-polluted soils. Residues, such as molasses, blood meal, and silage effluents, containing various aliphatic carboxylic acids, sugar acids, and amino acids or their precursor compounds were selected, hydrolyzed and oxidized, if required, and analyzed for their organic constituents. Soils that were contaminated with metals via sewage sludge amendment were extracted in batch and column experiments at various pH values. Grass silage effluent removed ∼75% of Cd and >50% of Cu and Zn at pH 4.4. The neutralized effluent was less effective except for Cu (69% leached). The neutral blood meal hydrolysate extracted primarily Cu (55−66%) and Ni (38−67%). Metal bonds attacked by this extractant were identified using a sequential leaching procedure. Hydrolysates containing sugar acids mobilized Cu and Pb under alkaline conditions. The actual results support the conclusion that biomass residues have a potential to serve as extractants in remediation techniques.

Dairy farming in Ireland generates an effluent known as dairy soiled water (DSW), which consists of a relatively dilute mixture of cow faeces, urine, spilt milk and detergents that is typically applied to grassland. However, relatively little is known about the volumes generated, nutrient content and management factors that influence volume and concentration. Sixty dairy farms that had a separate storage tank for storing DSW were selected for this study.
