Answer 1

Pesticides are chemicals that contain oxygen, sulfur, chlorine, nitrogen, phosphorus, and bromine as well as heavy metals such as copper, arsenic, sulfates, lead, and mercury – they are simply chemicals. They are used in the agriculture sector to control and/or eliminate pests. Pests such as insects, diseases, rodents and weeds can be harmful to crops if they are left uncontrolled and/or eliminated. And would otherwise damage them if they were allowed to thrive in agricultural land areas. As a result, pesticides are used to control and/or eliminate pests from agricultural land areas, thereby improving crop productivity and yields.

Excess of fertilizers are washed away into the surrounding water bodies. Thus, concentration of nitrates and phosphorus in the ground and surface water increases making it unfit for use.
