HORTICULTURE

Detailed explanation-1: -Nanomaterials employed for water, soil, and air remediation include metal oxides, carbon nanotubes, quantum dots, and biopolymers.

Detailed explanation-2: -Nanomaterials reaching in the land have the potential to contaminate soil, and migrate into surface and ground waters. Particles in solid wastes, waste water effluents, direct discharges, or accidental spillages can be transported to aquatic systems by wind or rainwater runoff.

Detailed explanation-3: -Air purification with ions, wastewater purification with nanobubbles or nanofiltration systems for heavy metals are some of its environmentally-friendly applications. Nanocatalysts are also available to make chemical reactions more efficient and less polluting.

Detailed explanation-4: -Air pollution can be remediated using nanotechnology in several ways. One is through the use of nano-catalysts with increased surface area for gaseous reactions. Catalysts work by speeding up chemical reactions that transform harmful vapors from cars and industrial plants into harmless gases.
