Environmental chemistry is the study of the chemistry of the natural world. This is sometimes related to, but is often separate from chemistry studies carried out in chemical laboratories. Environmental chemistry includes a number of sub-disciplines including atmospheric chemistry, geochemistry (see separate entry), biochemistry, and the related biogeochemistry. Biogeochemistry is concerned with chemical processes that take place as organisms interact with their environment. This might also be called ecological chemistry. Nutrient cycling is the study of the dynamics of the major chemical elements or macronutrients that control the productivity and metabolism of natural systems, including the carbon, nitrogen, phosphorus, sulphur, and silicon cycles. Plants require sufficient quantities of these and other elements for growth to take place and if one element is ...
