Hemp can clean up soil pollution
What can't hemp do?!
Not only does hemp rehabilitate and enrich the soil with nitrogen and oxygen, restore pH levels and combat erosion, industrial hemp can also naturally clean and detoxify soils that are contaminated with toxic substances and pollutants. Called 'phytoremediation', industrial hemp has a very high capability to absorb heavy metals like lead, nickel, cadmium, zinc and chromium.
Labelled a "mop-crop", industrial hemp can be used to clean up metals, pesticides, solvents, explosives, crude oil, and toxins leaching from landfills. Hemp and it's phytoremediative properties can also be used to remove radioactive elements from soil, having demonstrated the ability to decontaminate toxic soils in Chernobyl in the aftermath of the nuclear disaster.
How? The fast-growing, deep roots (around 8 feet below) of the hemp plant grow deep into the contaminated soil, and through their natural growth process, absorb, store or, in some cases, transform toxins into a harmless substance.
When heavy metals contaminate the environment, they remain a potential threat to humans and animals for many years to follow. With soil contamination increasing at a concerning rate due to human activities such as landfills, the releasing of industrial effluents/wastewater, and waste sludge, hemp and phytoremediation technology is an environmentally-friendly and cost-effective technology to repair our soils and environment.
