Chromium Estimated Population At Risk At Identified Sites: 7.3 Million People. Estimated Global Impact: 13 to 17 Million People. Introduction. Chromium is a naturally occurring heavy metal that is commonly used in industrial processes and can cause severe health effects in humans. Although it can be released through natural forces, the majority of the environmental releases of chromium are from industrial sources.
Chromium is pronounced as KROH-mee-em. History and Uses: Chromium was discovered by Louis-Nicholas Vauquelin while experimenting with a material known as Siberian red lead, also known as the mineral crocoite (PbCrO 4), in 1797.He produced chromium oxide (CrO 3) by mixing crocoite with hydrochloric acid (HCl).hromium can be polished to form a very shiny surface and is often plated to other metals to form a protective and attractive covering. Chromium is added to steel to harden it and to form stainless steel, a steel alloy that contains at least 10% chromium.
