RBSE Class 11 Chemistry Chapter 14 Notes Environmental Chemistry

→ Environmental Chemistry:
It is that branch of science which deals with the chemical phenomenon occuring in the environment i. e., study of origin, transport, reactions and effects of chemical species in the environment.

→ Environmental Pollution:
The addition of any undesirable material to air, water and soil by a natural source or due to human activity to such a level of concentration which adversely effects the quality of environment is called environmental pollution.

→ Pollutants: The undesirable materials thus added the environment are called pollutants.

→ Troposphere: It is the most important region of the atmosphere because it is the habitat of all living organisms including animals and plants.

→ Stratosphere: It is the region above the troposphere lying between 10km to 50. km above the sea level.

→ Troposphere Pollution: It is in the lowest portion of the atmosphere which extends to a height of about 10 km from sea level.

• Gaseous Air Pollutants: The pollutants such as oxides of carbon, sulphur and nitrogen, hydrogen sulphide etc.
• Particulate Pollutants: Small solid particles and liquid droplets suspended in the air are collectively called as particulates. Such as dust, mist, fumes, smoke, smog etc.

→ Green Chemistry: It deals with producing chemicals of generally used in Green Chemistry are used for our daily needs using such reactions and chemical processes which neither use toxic chemicals nor emit such chemicals into atmosphere. The techniques prevention of environmental pollution.
