USOS DEL CANNABIS EN LA BIORREMEDIACIÓN DE SUELOS CONTAMINADOS CON METALES PESADOS

<p><strong>Background. </strong>Bioremediation of soils contaminated with heavy metals is a vital area of research given the growing concern about environmental contamination. However, understanding of the ability of <em>Cannabis sativa</em> for this task has been limited. <strong>Objective</strong>. undertake a thorough analysis of the existing scientific literature to assess the role of Cannabis systematically and critically in the bioremediation of soils contaminated with heavy metals, emphasizing its effectiveness and potential applicability in restoring ecosystems affected by pollution. <strong>Methodology. </strong>A systematic review of the scientific literature was carried out, consulting databases such as ScienceDirect, Scopus, and SpringerLink. Relevant studies investigating the ability of <em>Cannabis sativa</em> to accumulate heavy metals and the factors affecting this process were selected and analyzed. <strong>Results. </strong>It was found that <em>Cannabis sativa</em>, especially the sativa variety and subvarieties such as Henola and Bialobrzeskie, exhibit a notable hyperaccumulation capacity of heavy metals, especially in roots and stems. Factors such as soil type, metal concentration, and weather conditions affect its effectiveness. <strong>Implications. </strong>These findings have important implications for agriculture and environmental management, offering a sustainable and less invasive alternative for the remediation of contaminated soils. However, the need to balance bioremediation with agricultural production and to properly manage the resulting waste is highlighted. <strong>Conclusions. </strong><em>Cannabis sativa</em> shows promising potential in the bioremediation of soils contaminated with heavy metals. Its hyperaccumulating capacity and the factors that influence its effectiveness offer significant opportunities for environmental restoration, remediation and sustainable resource management. The importance of future research is emphasized to maximize its effectiveness and minimize its impact on agricultural production.</p>
