The Determination of Algae Group as Bioindicator of Water Quality Change Affected by Mercury Release from Artisanal Small-Scale Gold Mining (ASGM)

Journal of Engineering and Technological Sciences, 2022
Artisanal small scale gold mining (ASGM) practices typically use mercury for amalgamation. Near water environments this can degrade water quality and aquatic biota, including algae. Changes in algal communities can reflect water environment disturbance.

Paving the Way to Elucidate Hg's Role in Tumorigenesis

Advanced Science, Volume 13, Issue 30, 28 May 2026.
Tumorigenesis can result from diverse environmental carcinogens. Among them, mercury—a lifelong bioaccumulative Group 2B carcinogen—has tumorigenic potential that remains poorly understood due to confounding co‐exposures and limited organ‐specific data.

Water and Artisanal and Small‐Scale Gold Mining: A Review of the Literature

WIREs Water, Volume 13, Issue 3, May/June 2026.
This paper reviews the relationships between artisanal and small‐scale gold mining (ASGM) and water. We show the variegated impacts ASGM has on water and, thus, socio‐ecological systems and health. We conclude by identifying gaps in the scholarship.

Senegalese artisanal gold mining leads to elevated total mercury and methylmercury concentrations in soils, sediments, and rivers

Elementa: Science of the Anthropocene, 2018
The largest source of global mercury (Hg) anthropogenic inputs to the environment is derived from artisanal and small-scale gold mining (ASGM) activities in developing countries.

Screening of Native Plant Species in the Artisanal Gold Mining Sites of Doko, Guinea: Perspectives for Phytoremediation

CLEAN – Soil, Air, Water, Volume 54, Issue 3, March 2026.
This study focuses on phytoremediation in a gold mining‐contaminated area in Doko, Guinea. Plant, soil, and rhizospheric soil samples were collected and subjected to physicochemical analyses to quantify heavy metal content. Biological indicators: bioconcentration factor (BCF), translocation factor (TF), and biological accumulation coefficient (BAC ...

Current Mercury Exposure from Artisanal and Small-Scale Gold Mining in Bombana, Southeast Sulawesi, Indonesia—Future Significant Health Risks

Toxics, 2017
The rapid expansion of the artisanal and small-scale gold mining (ASGM) industry in developing countries has marginalized the local communities in poverty, and resulted in occupational exposure to mercury via the gold extraction process.

Exposure to Toxic Metals (As, Cd, Hg, Pb) in Two Artisanal and Small-scale Gold Mining (ASGM) Areas in Zimbabwe

, 2020
Abstract Background: People living and working in ASGM areas are exposed to toxic metals such as arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb). Whereas Hg is purposely used to extract the gold from the ore, the other toxic metals can be liberated from the ore during the mining process.

Prenatal arsenic and mercury levels among women practicing geophagy in areas with artisanal and small-scale gold mining activities, Northwestern Tanzania

BMC Pregnancy and Childbirth, 2023
Background Artisanal and small-scale gold mining (ASGM) areas potentially pose increased exposure to arsenic and mercury through community contamination, occupations at gold mines, and/or geophagy when soil is locally sourced.
