A comprehensive characterization was performed to investigate the composition and mineralogy of soils from a gold mining region and their correlation with arsenic (As) total concentration and its bioaccessible fraction. The arsenic bioaccessible (BAC

An analytical protocol was developed to identify arsenic (As) in soil samples and in the ≤10 µm fraction of surface dust samples (fine surface dust-FSD). Single-particle identification of trace As constituents was undertaken by combining scanning

Bioaccessibility (BAC) of fine surface dust (FSD, particle size ≤10 μm) and surface dust samples (particle size ≤250 μm) collected from a gold mining district was used as a tool to determine the portion of arsenic that would be available via si

Internal sulfate attack is one of the most harmful deterioration mechanisms to concrete. A testing procedure was developed to evaluate how reactive is a sulfide-bearing aggregate to use in concrete. The aggregates were produced from iron sulfide rock
