"A spectroscopic study to assess heavy metals absorption by a combined hemp-spirulina system from contaminated soil"

The efficiency of hemp (Cannabis sativa L.) in remediating sites contaminated with heavy metals has received great attention in recent years. The main advantage of this technology relies on its inherent sustainability, with a potential re-utilization of the significant amount of produced biomass, which acts as a valuable flow resource. In this study, a combined system consisting of Cannabis sativa L. (hemp) and the blue-green alga Arthrospira platensis (spirulina) was tested to clean up soils contaminated with cadmium, chromium, copper, nickel, lead, and zinc. The application of non-targeted nuclear magnetic resonance spectroscopy (NMR) methods ... (Full article...)
