“…These studies lay the groundwork for issues that must be mitigated and eliminated. The analysed database reflects that, over time, studies developed that focus on solutions to problems generated by ASM (e.g., [238,239,241,253,256,268,278,294,318,319]). However, despite the worldwide importance and impact of research aimed at ASM solutions, it is still scarce (less than 20% of the analysed database).…”

“…Faced with this problem, finding innovative research to eliminate, replace, or reduce environmental pollution in mineral processing is standard. Some examples are the cyanide phytoremediation by water hyacinths (Eichhornia crassipes) in the cyanide effluents treatment in small-scale gold mining [253], hyperaccumulation of zinc by Corydalis davidii in Zn-polluted soils [254], Erato polymnioides as a phytoremediation plant for soils contaminated with Pb, Zn, Cu, and Cd [255], and Heliconia psittacorum in remediating soils and water polluted with heavy metals [256].…”

Mineral resource exploitation is one of the activities that contribute to economic growth and the development of society. Artisanal and small-scale mining (ASM) is one of these activities. Unfortunately, there is no clear consensus to define ASM. However, its importance is relevant in that it represents, in some cases, the only employment alternative for millions of people, although it also significantly impacts the environment. This work aims to investigate the scientific information related to ASM through a bibliometric analysis and, in addition, to define the new lines that are tending to this field. The study comprises three phases of work: (i) data collection, (ii) data processing and software selection, and (iii) data interpretation. The results reflect that the study on ASM developed intensively from 2010 to the present. In general terms, the research addressed focuses on four interrelated lines: (i) social conditioning factors of ASM, (ii) environmental impacts generated by ASM, (iii) mercury contamination and its implication on health and the environment, and (iv) ASM as a livelihood. The work also defines that geotourism in artisanal mining areas is a significant trend of the last decade, explicitly focusing on the conservation and use of the geological and mining heritage and, in addition, the promotion of sustainable development of ASM.

“…La especie utilizada fue la Heliconia psittacorum que, debido a su amplio espectro de tolerancia a cambios ambientales drásticos, es capaz de sobrevivir a temperaturas que oscilan entre 18°C y 34°C. Esto posibilita la adaptación al medio en ecosistemas del trópico, condiciones propias del lugar de estudio (Decezaro et al, 2018;Orejuela et al, 2018;Samuel et al, 2022). Las plantas fueron obtenidas en un vivero de la zona de estudio, su acondicionamiento se realizó sobre el lecho del humedal durante 20 días, partiendo con una mezcla entre agua cruda y agua residual proveniente del entable minero en proporciones 1:1 por 5 días.…”

Antecedentes. La contaminación por mercurio (Hg) producto del beneficio minero aurífero es un problema de índole ambiental, dada su capacidad de afectar los ecosistemas y la salud humana. Por lo cual, es fundamental proponer alternativas enfocadas en disminuir la contaminación producida principalmente al recurso hídrico, debido a la persistencia y permanencia de este metal pesado en el ambiente Objetivo. Evaluar la remoción de Hg y la carga orgánica del agua residual proveniente de un entable minero mediante un sistema de humedales de flujo subsuperficial horizontal. Métodos. Se realizó la caracterización fisicoquímica del agua residual minera, además, se diseñó y operó un sistema de tres humedales a los cuales se les varió el Tiempo de Retención Hidráulica (TRH) y la presencia o ausencia de Heliconia psittacorum, se evaluaron parámetros como pH, OD, turbidez, DBO 5 , DQO y Mercurio. Se aplicó una prueba estadística ANOVA con significancia del 95%. Resultados. El efluente minero arrojó concentraciones para DQO y Hg de 197 mg O 2 /L y 0,0021 mg/L, respectivamente, valores superiores a los permisibles por la normativa colombiana y de la EPA. Los humedales evaluados mostraron eficiencias de remoción para turbiedad, DBO 5 , DQO y Hg superiores al 98,44%, 93,10%, 71,52% y 91,03%, respectivamente. Las pruebas estadísticas sugieren que no existe diferencia significativa con respecto a la variación del TRH, pues los porcentajes de eficiencia de remoción del Hg para 2 y 4 días son relativamente similares Conclusiones. Los humedales de flujo subsuperficial horizontal y Heliconia psittacorum, son altamente eficientes en la remoción de Hg de aguas residuales de minería aurífera, consolidándose como una tecnología prometedora para la biorremediación ambiental.

“…Samuel et.al [5] Studied on "irrigation of the Heliconia psittacorum with 10 ppm each of the heavy metals (mercury (Hg), arsenic (As), cadmium (Cd) and lead (Pb) and metalloid. The roots and shoots of the plant were analysed for the number of heavy metals and metalloid absorbed by the plant after specific periods.…”

Soil contamination has become a serious problem in many industrialized and developing countries. Indiscriminate dumping of urban and industrial effluents along with solid waste often lead to toxic accumulation of heavy metal ions which not only impair soil productivity but also cause health hazards by entering into food chain via soil-plant-animal/human route. With rapid urbanization and industrialization, large quantities of industrial effluents get mixed with sewage and river water [1]. Irrigating crop fields with such contaminated sewage water is being increasingly adopted by marginal farmers due to scarcity of irrigation water. It also inadvertently leads to addition of large quantity of heavy metals to the agro ecosystem [2]. Plants with abilities to hyperaccumulate, accumulate, exclude and indicate heavy metals are important in environmental remediation. Most phytoremediation studies are aimed at inorganic pollutants through different approaches defined as phytoextraction (the used of metal accumulating plants to transport and concentrate metals from the soil to roots and above ground biomass), rhizofiltration (the use of plant roots to absorb, precipitate, and concentrate toxic metals from polluted effluents), and phytostabilization (the use of plants to reduce the mobility of metals)
