Past and present economic activities have often resulted in contamination of the soil underlying the place, where these activities took place. Contaminants affecting soil may be in the form of solids, liquids or gases. The most common toxic soil pollutants include metallic elements and their compounds, organic chemicals, oils and tars, pesticides, explosive and toxic gases, radioactive materials, biologically active materials, combustible materials, asbestos and other hazardous minerals. 
 Human activity leads to chemical compounds being discharged into the aquatic environment in various ways, for example in domestic sewage water and industrial effluent, through mining and through atmospheric deposition. These contaminants represent a threat both to aquatic ecosystem and to human health - a threat that is intensified by vast number of new synthetic organic compounds being produced and released into the environment.
