Inorganic constituents are present in major, minor, and trace concentrations in aquatic environments as a result of weathering, atmospheric, and biogeochemical processes, and also as a consequence of industrial pollution. Inorganic constituents in aquatic ecosystems are a group of chemical species that are characterized by

1. A wide variety of chemical structures, from simple monoatomic ions and molecular ions to complex molecules.
