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.

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.

Introduction: Mobile migrants are subject to restricted healthcare access, which may result in the spread of certain infectious diseases. The aim of this study is to evaluate the burden of a subset of priority infectious diseases in mobile migrants in remote gold mining areas in the forested interior of Suriname.
Methods: This cross-sectional study enrolled mobile migrants in 13 study sites between January and June 2022.

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).
