Environmental chemistry could be a branch of chemistry, comprising aspects associated with chemical science, chemistry, analytical chemistry and chemistry, moreover as additional numerous areas, like public health, biology, organic chemistry, toxicology, and medical specialty. Environmental chemistry is the study of chemical processes occurring within the setting that area unit compact by mankind's activities and therefore the impacts could also be felt through the presence of air pollutants or cytotoxic substances from a chemical waste web site, or through depletion of stratospheric gas which can have an effect on warming. the current environmental issues result in the redress of environmental media, and to new, low energy, low emission, and property processes. Environmental chemistry describes the pollution of air, water, food and living organisms by cytotoxic metals, soils, fossil fuels, pesticides and organic pollutants. Green chemistry highlights novel chemical reactions that area unit environmentally friendly.
