Chromium (Cr) is a potentially toxic metal originating from natural processes and
anthropogenic activities such as the iron-steel, electroplating, and leather industries, which …

Chromium (Cr) is the seventh most abundant chemical element in the Earth's crust, and Cr
(III) and Cr (VI) are common stable valence states of Cr. Several Cr-containing substances …

Site-specific Fe 2+ generation is promising for tumor therapy. Up to now, reported materials
or systems for Fe 2+ delivery do not naturally exist in the body, and their biological safety …

Soils are common sources of metal (loid) contaminant exposure globally. Lead (Pb) and
arsenic (As) are of paramount concern due to detrimental neurological and carcinogenic …

Iron oxides can be applied as adsorbents to remove harmful substances from the water used
in the textile process. If these oxides can be synthetized through acid digestion of ferrous …

Iron (oxyhydr) oxides are highly reactive, environmentally ubiquitous organic matter (OM)
sorbents that act as mediators of terrestrial and aqueous OM cycling. However, current …

Mine wastes pollute the environment with metals and metalloids in toxic concentrations,
causing problems for humans and wildlife. Microorganisms colonize and inhabit mine …

Iron (hydr) oxide nanoparticles are one of the most abundant classes of naturally occurring
nanoparticles and are widely used engineered nanomaterials. In the environment these …

Biogenic Fe (II) is a dominant natural reductant to convert carcinogenic Cr (VI) to less toxic
Cr (III). Field-applied biochar could promote microbial production of Fe (II) and form iron …

Sukinda Valley, one of the highly polluted areas of the world is generating tons of mining
waste and causing serious health and environmental issues in its surroundings. Several …
