“…Obeng et al (2019) investigated the impact of illegal mining activities (galamsey) on the forest ecosystem in local communities and found that over 70% of the respondents were extremely concerned about the decline in the quality of water resource and the drying up of streams and rivers due to galamsey. Attiogbe et al (2020) found human activities like galamsey, liquid waste discharge and leachate from dumping sites to be the main contributors to the higher level of zinc in Lake Amponsah at Bibiani in Western region of Ghana. Tahiru et al (2020) assessed the impact of land use land cover changes on water quality in the Nawuni catchment of the White Volta Basin over a ten-year period (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017) and observed that levels of ammonia, turbidity and total coliforms continued to increase over the period studied, while closed savannah, bare lands, grassland or farmland and settlement increased in the same period.…”

Illegal mining and inappropriate use of agrochemicals have exacerbated surface water pollution in Ghana. The quality of water has changed, and knowledge of their current condition is important for formulating policies to conserve the country's water bodies. This study assessed the quality of surface waters in Ghana's Pra River Basin. A survey of 344 local farmers randomly sampled was conducted and a physicochemical analysis of 33 water samples collected from 25 rivers in the basin. Boreholes are the main source of drinking water for 85% of farmers, and they assessed water quality by its appearance. Rainwater provides over 50% of the water needed by the respondents for domestic use. River water was mainly used for crop production and only secondarily for domestic use. At more than 80% of the sampled sites, pH, Fe and P were above the WHO recommended values, while Pb was exceeded at 30% of the sites. Cu, Hg, As and Fe were above permissible levels for irrigation, especially near the mining areas. The poor quality of river water makes it unusable despite its availability. A more effective and efficient land-use policy focusing on buffer zone protection is recommended to minimise water quality degradation in the basin.

“…Mostramos que existen grandes cantidades de mercurio que se vierte a la atmosfera, a los suelos y cuerpos de agua por parte de la minería a pequeña escala que se utiliza en la amalgamación (Calao et al, 2021). El hecho de tener más de 70,000 mineros informales en 23 regiones del país y un promedio de 5,000 operadores mineros en la región Puno que a su vez generan otros puestos de trabajo directo e indirecto, explica, como lo señalan Attiogbe et al (2020), que la minería tiene un rol importante económico y social.…”

“…No se puede negar que la minería hace una contribución económica y social en el desarrollo, pero a la vez sus impactos ambientales son significativos (Attiogbe et al, 2020), principalmente en fuentes de agua que elevan sus concentraciones de metales pesados, excediendo los estándares de calidad de los recursos hídricos (Attiogbe & Nkansah, 2017;Siddiqui & Pandey, 2019). Estos impactos ambientales no solo se dan en el agua, también se distribuyen en el suelo próximo a las operaciones de extracción de oro (Niane et al, 2019), donde el principal insumo es el mercurio, que tiene efectos graves sobra la salud de las personas (Budnik & Casteleyn, 2019).…”

La minería de pequeña escala crece cada vez con mayor número de operadores en diferentes partes de mundo. La región Puno, en Perú, no escapa a esta tendencia; colateralmente los impactos negativos en los ecosistemas son cada vez mayores. El objetivo del estudio es determinar la presencia de metales pesados producidos por la actividad minera artesanal en las provincias de Sandia, Carabaya y San Antonio de Putina. Se tomaron siete muestras puntuales de agua próximas a las operaciones de las tres provincias, muestras que fueron evaluadas en un equipo de espectrometría de plasma (ICP); y diez muestras en el centro poblado de La Rinconada analizadas en un equipo Milestone DM 80 exclusivo para análisis de mercurio. En el primer grupo se presentaron aluminio (Al) en rangos de 7,79 hasta 66,2 mg/L; cromo (Cr) con una muestra con 0,12 mg/L; hierro (Fe) con rangos de 36,1 a 280 mg/L; mercurio (Hg) con rangos de 0,0158 a 0,1301 mg/L; manganeso (Mn) variando de 0,4004 a 6,5092 mg/L y níquel (Ni) con valores entre 0,2278 y 1,2148 mg/L. De seis muestras cinco presentan metales que superan los estándares de calidad ambiental para riego y bebida de animales. En La Rinconada, donde operan más de 400 contratistas que conviven con alrededor de 30,000 personas, los análisis arrojaron resultados que varían entre 0,0013 y 0,0188 mg/l para mercurio, superiores a los permisibles de acuerdo con la norma nacional e internacional.

“…It was recommended that control measures of HM discharge into the canal should be implemented according to standard regulations stipulated in Law 48/1982 of the Nile River protection. Attiogbe et al., (2020) [37] Assessed the possible health impact of certain HMs polluting lake amponsah in Bibiani, Ghana's western North area. The study revealed that the concentrations of Hg, Cd, and As were all over the Ghana Environmental Protection Agency level, except for Zn.…”

Heavy metals present in wastewater and water scarcity are a global challenge worldwide. The elimination of heavy metals in wastewater is necessary to protect the ecosystem and human health. Heavy metals such as lead, cadmium, and mercury are among many other toxic heavy metals present in wastewater. There are several conventional methods that have been implemented to mitigate heavy metal pollution in wastewater and according to literature, it has been evident that the nanofiltration (NF) separation technique requires minimal pressure to obtain high rejections of multivalent inorganic salts compared to conventional methods. NF separation process is highly competitive in terms of selectivity and cost‐benefit. The growing research trend of NF fabrication and modification collates that the technology has been applied in various industrial and municipality wastewater treatment facilities. The review paper aims to illustrate the health impacts of heavy metal exposure, the cons of conventional methods and the utilization of NF membranes in wastewater treatment, the overall factors affecting membrane performance, and future aspects of the separation techniques.
