Metabolic interactions between metals and metalloids.

How Saccharomyces cerevisiae copes with toxic metals and metalloids.

Toxic metals and metalloids are widespread in nature and can locally reach fairly high concentrations. To ensure cellular protection and survival in such environments, all organisms possess systems to evade toxicity and acquire tolerance. This review provides an overview of the molecular mechanisms that contribute to metal toxicity, detoxification and tolerance acquisition in budding yeast Sacc...

Mobility and biovailability of HM and metalloids in the soil, Violante et al. MOBILITY AND BIOAVAILABILITY OF HEAVY METALS AND METALLOIDS IN SOIL ENVIRONMENTS

In soil environments, sorption/desorption reactions as well as chemical complexation with inorganic and organic ligands and redox reactions, both biotic and abiotic, are of great importance in controlling their bioavailability, leaching and toxicity. These reactions are affected by many factors such as pH, nature of the sorbents, presence and concentration of organic and inorganic ligands, incl...

Speciation of trace metals and metalloids by solid phase extraction with spectrometric detection: a critical review

Considerable interest is continuing to be shown in the speciation of metals, metalloids, and organometals due to the dependence of their toxicity and mobility on their chemical form. This review focuses on the speciation analysis of metals, metalloids, and organometals by solid phase extraction before spectrometric detection, and all aspects of analytical speciation such as determination of oxi...

Sorption of metals and metalloids from reverse osmosis concentrate on drinking water treatment solids

Drinking water treatment solids (DWTS) from coagulation processes could be a low-cost sorbent for selective removal of certain metals and metalloids from brine. In this study, continuous-flow sorption processes and factors affecting sorption of boron (III), copper (II), chromium (VI), lead (II), and selenium (VI) from reverse osmosis (RO) concentrate were investigated using different types of i...
