Projecting Global Mercury Emissions and Deposition Under the Shared Socioeconomic Pathways

Earth's Future, Volume 12, Issue 4, April 2024.
Abstract Mercury (Hg) is a naturally occurring element that has been greatly enriched in the environment by human activities like mining and fossil fuel combustion. Despite commonalities in some carbon dioxide (CO2) and Hg emission sources, the implications of long‐range climate scenarios for anthropogenic Hg emissions have yet to be explored. Here, we

Assessing fish diversity in abandoned mining ponds in Madre de Dios, Peru, using environmental DNA

Environmental DNA, Volume 6, Issue 1, January–February 2024.
We surveyed four lentic systems in Madre de Dios, Peru: two abandoned mining ponds created by ASGM and two unmined oxbow lakes as a reference to assess fish recolonization. We compared two alternative eDNA processing methods and contrasted our results with historic data from traditional biodiversity monitoring. Our results indicate that eDNA could be a

Physicochemical Characterisation of Water and Sediment of the Semimechanized Artisanal Gold Mining Environment of the Béké Locality

Applied and Environmental Soil Science, Volume 2024, Issue 1, 2024.
This paper aims to investigate the level of pollution of water, sediment, and soil due to semimechanized artisanal gold mining in Béké, Adamawa region of Cameroon. For this purpose, water and sediment samples were collected and analyzed. In order to achieve this goal, several research studies and field observations were carried out. Questionnaires were
