To circumvent some of the previous limitations associated with contaminant-monitoring programs, we tested the suitability of the water strider (Hemiptera: Gerridae) as a mercury sentinel by comparing total mercury concentrations in water striders and brook trout (Salvelinus fontinalis) from a variety of stream sites in New Brunswick, Canada. There was a strong association between the two variab...

In this letter, we propose a Deep Learning (DL) based approach which exploits multispectral Sentinel-2 open-source data and small-size inventory to map artisanal small-scale mines (ASM). The study area is in central northern Burkina Faso (Africa) characterized by semi-desert environment that makes mapping challenging. sub-Saharan Africa, mining represents source of subsistence for significant n...

This study represents a joint pilot project between archaeological and natural sciences, aimed at exploring the technology and provenance of gold artefacts, exemplified for the case of Georgia. It is focussed on the prehistoric gold mine of Sakdrisi. The study included the investigation of both Bronze Age gold artefacts and native gold by chemical and lead isotope analyses using ICP-mass spectr...

Abstract The most common method used for gold processing in artisanal and small-scale mining is amalgamation using mercury as a extracting agent. Indonesia one of the countries that ratify Minamata Convention, meaning has agreed to reduce or even eliminate use mercury. Some methods replacing gold-extracting agent are cyanidation borax. research aims determine whether miners Pelangan still proce...

This paper explains the history of first ethical gold certification programme: Fairtrade and Fairmined Gold, launched in February 2011, its two successors. By presenting an overview key events that occurred UK Switzerland relating to these three leading schemes, it outlines trajectory relevance both countries up present day. material is then used explain why has survived but remained peripheral...

The study analyzed the information needs and accessibility of artisanal fisher folk in Benue State, Nigeria. Multistage sampling technique was used to select two fishing communities from each of the three agro-ecological zones in the study area. A structured questionnaire was used to collect primary data from 222 respondents. Descriptive statistics showed that artisanal fisher folk were mostly ...
