Environmental chemistry is the study of chemicals, which by their absence or presence in critical amounts, influence life on land and in water.  Environmental chemistry includes the chemicals that influence the levels of critical chemicals such as oxygen and carbon dioxide.  Hence environmental chemistry is concerned with contamination of the atmosphere and water resulting from industrial pollution.  Environmental chemistry includes methods of detection, quantifying the presence, and measuring differences from the natural state, as well as their effects.
