  1. Soil chemistry

    Soil chemistry is the study of the Chemistry chemical characteristics of soil . Soil chemistry is affected by mineral composition, organic matter and Environment biophysical environmental factors. History Until the late 1960s, soil chemistry focused primarily on chemical reactions in the soil that contribute to pedogenesis or that affect plant growth. Since then, concerns have grown about environmental pollution , organic and inorganic soil contamination and potential ecological health and environmental health risks . Consequently, the emphasis in soil chemistry has shifted from pedology and agricultural soil science to an emphasis on environmental soil science . Environmental soil chemistry A knowledge of environmental soil science environmental soil chemistry is paramount to predicting the fate, mobility and potential toxicity of contaminants in the environment. The vast majority of environmental contaminants are initially released to the soil. Once a chemical is exposed to the soil environment a myriad of chemical reaction s can occur that may increase or decrease contaminant toxicity. These reactions include adsorption desorption , Precipitation chemistry precipitation , polymerization , solvation dissolution , complexation and redox oxidation reduction . These reactions are often disregarded by scientists and engineers involved with environmental remediation . Understanding these processes enable us to better predict the fate and toxicity of contaminants and provide the knowledge to develop scientifically correct, and cost effective remediation strategies.
