Chromium metal is an essential trace element, but hexavalent chromium (Cr(VI)) is very toxic and carcinogenic.

Chromium contains the carcinogenic and mutagenic chromate ions.

Chromium can cause harm to the local ecosystem if poured into the water supply.

Chromium is from the Greek word chroma, color. Chromium is a steel-gray, lustrous, hard metal that takes a high polish. Discovered in 1797 by the Frenchman Louis Nicolas Vauquelin.
