- Abstract
This article discusses the physicochemical properties of artificial soil mixed with fly ash, sewage sludge and mine tailings in China. Water holding capacity was measured with simulated rainfall evaporation and heavy metals (copper, lead, zinc and nickel) were analyzed by atomic absorption spectrophotometry. According to the authors, after several days, most artificial soil mixtures increased in water holding capacity, pH increased indicating decreasing acidity, and the electrical conductivity decreased indicating less salinity in the soil. Heavy metals were found to be below the toxicity thresholds.
