#CHROMIUM CHARGE SKIN#
Dermal exposure of the general public to chromium can occur from skin contact with certain consumer products or soils that contain chromium. The general population may be exposed to chromium by inhaling ambient air, ingesting food, and drinking water containing chromium. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons.The nucleus is composed of protons and neutrons.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Chromium is released to the environment from natural and anthropogenic sources, with the largest releases occurring from industrial sources. Chromium is widely used in manufacturing processes, and it can be found in many consumer products such as wood treated with copper dichromate, leather tanned with chromic sulfate, and stainless steel cookware. The three main forms of chromium found in the environment are chromium (0), chromium (III), and chromium (VI), also known as hexavalent chromium. The draft Toxicological Review of Hexavalent Chromium provides scientific support and rationale for the hazard and dose-response assessment pertaining to chronic exposure to hexavalent chromium via ingestion.Ĭhromium is a naturally occuring element in the earth's crust.
