... For example, accumulation of nitrogen-rich nutrients in some water bodies (lakes and rivers) from farm run-off results in “algal blooms” that leads to condition known as eutrophication. That is, the deplication of water oxygen content that causes suffocation to fish and other aquatic lives. Nitroge ...

Inorganic chemistry
Inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds. This field covers all chemical compounds except the myriad organic compounds (carbon based compounds, usually containing C-H bonds), which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, and there is much overlap, most importantly in the sub-discipline of organometallic chemistry. It has applications in every aspect of the chemical industry–including catalysis, materials science, pigments, surfactants, coatings, medicine, fuel, and agriculture.
