Exploring the Potential of Industrial Hemp in Phytoremediation of Heavy Metals

Abstract

Extensive research has explored the potential utility of industrial hemp (<i>Cannabis sativa</i>) in phytoremediation, particularly its ability to alleviate soil pollution caused by heavy metals—a significant threat to human health and the environment. Various industrial activities, including mining, smelting, and manufacturing, can introduce heavy metals into the soil. Phytoremediation harnesses the unique detoxification abilities of plants like cannabis to rehabilitate polluted sites. Studies indicate that cannabis exhibits remarkable proficiency in extracting heavy metals like lead, cadmium, and nickel from contaminated soil, accumulating them in its tissues. This highlights the promising potential of cannabis as a candidate for phytoremediation. Noteworthy attributes such as hemp's deep roots and robustness enable it to endure diverse metal accumulations, and its biomass presents numerous commercial opportunities post-harvest. Additionally, research suggests that the integration of mycorrhizal fungi may enhance cannabis' phytoremediation capabilities. These symbiotic fungi establish beneficial relationships with plants, promoting nutrient absorption and fortifying environmental resilience.
