Petrochemistry and Chemical Engineering

Environmental chemistry is the scientific review of the chemical and biochemical phenomena that occur in natural places. Environmental chemistry can be described as the study of the sources, reactions, transport, effects of chemical species in the air, soil, and water environments; and the effect of human activity on these. Environmental chemistry is an integrative science that includes atmospheric, aquatic and soil chemistry, as well as uses analytical chemistry. It is allied to environmental and other areas of science. It is different from green chemistry, which tries to trim potential pollution at its source.

Whereas Environmental engineering deals with the combination of sciences and engineering principles to develop the natural environment, to provide healthy air, water, and land for human habitation and for other organisms, and to procure pollution sites.
