This study evaluates the diet composition of a rural population near a gold mine in the Cajamarca district of Peru. The main consumed items by this population were tubers and cereals, and the mean energy intake (1990 kcal) was shown not to cover the recommended intake values for the male population. The concentrations of As, Cd, Hg, Pb, Zn, Al, Cr and, Cu in drinking water and food samples of items contributing to 91% of this diet (145 samples, 24 different items) were determined and used to calculate their daily intakes for risk assessment. The As, Cd and Pb daily intakes exceeded the limit values established by the European Food Safety Authority (EFSA), entailing serious concerns for the population's health. Moreover, the intake values of As and Pb were shown to be higher, the closer to the gold mine the studied population was.

Department of Environment and Sustainable Development, Singidunum University, Danijelova 32, 11010 Belgrade, Serbia.

The growing demand for metal production promotes the search for alternative sources and novel modalities in metallurgy. Flotation tailings are an important secondary mineral resource; however, they might pose a potential environmental threat due to containing toxic metals. Therefore, proper leaching reagent selection is required.

Creep model of bond-degradation in deep granite based on variable radius particle clump.

Sci Rep

January 2025

Xincheng Gold Mine of Shandong Gold Mining Co., Ltd., Laizhou, 261400, Shandong, China.

The creep failure of rocks is related to its microstructure, external loading and time. A nonlinear yield model was introduced to describe the variation in the cohesion and friction angle with plastic strain and intergranular stress. The mechanical properties and creep characteristics of deep granite were obtained by indoor tests, and a variable radius particle clump model was constructed based on the particle flow method.

Mercury pollution is a significant environmental issue, primarily resulting from industrial activities, including gold mining extraction. In this study, 333 microorganisms were tested in increasing mercury concentrations, where 158 bacteria and 14 fungi were able to grow and remain viable at concentrations over 5.0 mg/L of mercuric chloride (II).

Article Synopsis
  • Galamsey, a Ghanaian term meaning "gather and sell," refers to informal gold mining that, while economically beneficial, poses serious environmental threats, especially to aquatic ecosystems.
  • The paper utilizes the Driver-Pressure-State-Impact-Response framework to analyze how pollutants from galamsey affect water quality and ecosystem services, revealing significant deviations from safe levels of mercury, arsenic, and turbidity in surface water.
  • Key findings indicate substantial negative impacts on ecosystem services like drinking water, recreation, and aquaculture, with varying levels of severity, prompting calls for cleaner, more responsible mining practices.
