Environmental Science Environmental Science is multi-disciplinary science involving chemistry, physics, life science, agriculture, medical science, public health, sanitary engineering etc. It is the science of chemical phenomena in the environment. In broad sense, it is the study of the sources reactions transport effect fate of chemical species in the air, water and soil and the effect of human activity upon these. Therefore, an understanding of the basic concepts of environmental chemistry is essential not only for all chemists but also for all non-chemists engaged in environmental science, engineering and management.

Environmental Segments Earth is the only planet on which life exists. It consists of three components Lithosphere (Land), Hydrosphere (Water) and Atmosphere (Air). Life originated and evolved because of this unique combination of the three components and was ideal and favourable for life. The life supporting zone of the earth where atmosphere, hydrosphere and lithosphere meet, interact and make life possible, is known as biosphere. The environment consists of various segments like     Atmosphere Hydrosphere Lithosphere Biosphere  The lithosphere, hydrosphere and atmosphere are non-living components of the environment and are known as abiotic.
