Aquatic ecosystems have been suffering deleterious effects due to the development of different economic activities. Metal(loid)s are one of the most persistent chemicals in environmental reservoirs, and may produce adverse ...

Metals, metalloids and nonmetals concentrations along the Suquía River basin have been monitored in sediment and surface water, during the wet and dry season, at different points and by different authors since 1997 until ...

This review is focused to cover the application of different analytical techniques for the determination of metals and metalloids in different categories of dietary supplements. Atomic spectrometric methods based on flame ...

Chemical speciation is a relevant topic in environmental chemistry since the (eco)toxicity, bio (geo)chemical cycles, and mobility of a given element depend on its chemical forms (oxidation state, organic ligands, etc.). ...

Aquatic environments are dynamic systems, where metals and metalloids are continuously transformed and mobilised through different chemical forms among organic and inorganic substances and particulate material. These ...

Sinter deposits are formed by precipitation of silica from hydrothermal fluids that have reached the surface environment. They are commonly found around hot springs and represent surface expressions of underlying geothermal ...
