Environmental Chemistry is the study of chemical processes happening in the environment which are influenced by humankind's affairs. These effects may be felt on a local scale, through the existence of urban cities' air pollutants or toxic substances emerging from a chemical waste site, or on a global scale, by the exhaustion of stratospheric ozone or global warming.
Green Chemistry is the representation of chemical byproducts and processes that bring down or eliminate the utilize or creation of hazardous substances. Green chemistry relates across the life cycle of a chemical product, counting its design, construct, use, and ultimate dumping. Green chemistry is also called Sustainable chemistry.
