Abstract Artisanal and small-scale gold mining (ASGM) utilizes mercury (Hg) for the extraction of (Au) is responsible largest anthropogenic source emissions releases Hg to environment. Previous estimates use in ASGM have varied widely. In this effort, losses were derived from difference between total Au production reported by conventional mining. On basis result, average ratio lost produced was...

Abstract Increased prices and political pressure are boosting illegal gold mining in the Brazilian Amazon, threatening forests, indigenous people, conservation of biodiversity protected areas. The rate deforestation increased more than 90% from 2017 to 2020, reaching 101.7 km 2 annually 2020 compared 52.9 2017. In that period, grew clearing within leases. While formal is required comply with en...

The artisanal fisheries of Ecuador operate within one of the most dynamic and productive marine ecosystems of the world. This study investigates the catch composition of the Ecuadorian artisanal fishery for large pelagic fishes, including aspects of its spatio-temporal dynamics. The analyses of this study are based on the most extensive dataset available to date for this fishery: a total of 106...

This article is one of three synthesis reports resulting from an integrated assessment (IA) of artisanal and small-scale gold mining (ASGM) in Ghana. Given the complexities that involve multiple drivers and diverse disciplines influencing ASGM, an IA framework was used to analyze economic, social, health, and environmental data and to co-develop evidence-based responses in collaboration with pe...

Integrated field studies on environmental levels, bioavailability, biological exposure, and effects SUMMARY Iron-ore is the source of primary iron for the world's iron and steel industries. Almost all (98%) iron-ore is used in steelmaking. Australia and Brazil together dominate the world's iron-ore production, while China is the world's largest iron-ore consumer. In Brazil, iron-ore mining is m...

Artisanal and small-scale gold mining (ASGM) is inherently risky, but little is known about mining-associated hazards and injuries despite the tremendous growth worldwide of ASGM and the benefits it offers. The current study aimed to characterize the physical injuries associated with ASGM in Ghana to guide policy formulation. A cross-sectional survey was carried out in the Tarkwa mining distric...

Mining can be the source and target of opportunities threats different natures exceeding mine site perimeter, affecting socio-ecological system leading to social conflicts entrepreneurial risks for mining companies. Hence, a project is matter land planning rather than simple industrial object. Nevertheless, current mandatory risk impact assessment methods are often performed on one at time, neg...

In regions affected by artisanal and small-scale gold mining (ASGM), the inhalation of mercury vapor and the ingestion of fish contaminated with this metal constitute the main sources of mercury contamination that affect human health. Nevertheless, according to the World Health Organization, another source of contamination is polluted water. Although mercury in freshwater is usually found in ve...

This paper contributes to the growing literature on dynamics and governance challenges of artisanal mining in sub-Saharan Africa. It examines gold sector Liberia Sierra Leone, two neighboring post-war countries with extensive informal economies sector. comparative case study explores factors that help reveal struggles, including informality sector, multiplicity actors, ineffective monitoring, p...

Currently, the impacts of Covid-19 are receiving significant global attention. This also applies to extractive industries, where this crisis is directing gaze policymakers, donors and academics alike. seen as having far-reaching disruptive consequences, especially in case artisanal small-scale mining. While authors consider attention important, their work on mining Ghana – West Africa more broa...
