Iron (Fe) - Chemical properties, Health and Environmental ...

CharacteristicsUseCompositionToxicityHealthSafetyIron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table). It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids. Iron is chemically active and forms two major series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III), or ferric, compounds.

A clearer look at how iron reacts in the environment ...

Sep 06, 2012 ARGONNE, ILL. (Sept. 6, 2012) — Using ultrafast X-rays, scientists for the first time have watched how quickly electrons hop their way through rust nanoparticles. This gives key insight to how iron oxide, one of the most abundant minerals in soil, behaves and alters the condition of soil and water around it. This also demonstrates the potential of time-resolved X-ray and optical methods to ...

The Effects of Iron in Water on Aquatic Life Cuteness

Iron in water has many effects on aquatic life, both good and bad.

What Is The Environmental Impact Of The Mining Industry ...

Air PollutionWater PollutionDamage to LandLoss of BiodiversityAir quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining. Wind erosion and nearby vehicular traffic cause such materials to become airborne. Lead, arsenic, cadmium, and other toxic elements are often present in such particles. These pollutants can damage the health of people living near the mining site.
