The worisome byproduct of stainless steel welding is hexavalent chromium, also refered to as Cr(VI). A. Hexavalent chromium Cr(VI) is a metal particle that can occur naturally in rocks, but most commonly is produced by industrial processes. The intensity of the color development is directly related to hexavalent chromium content.

(Fig 3) While squeezing gently, rub the swab on the test area for 30 seconds. Cr (VI) can enter the environment through many processes such as, but not limited to, cooling towers and water plants, plating operations, the tanning industry, and from paint pigments. Chromium is a naturally occurring element found in rocks, animals, plants, soil, and volcanic dust and gases. Monitoring methods for hexavalent chromium include NIOSH Methods 7604 (by ion chromatography) and 7600 (by visible absorption spectrophotometry) or OSHA Method ID-215 (noted in the hexavalent chromium standard). One of the more superior brands is 3M. Chromium is a metal that exists in several oxidation or valence states, ranging from Cr-2 to Cr+6 (hexavalent chromium). It has the ability to gain electrons from other elements; it is a strong oxidizer, which means it can react easily with other elements. The Air-O-Cell® is designed for the rapid collection of a wide range of airborne aerosols including mold spores, pollen, insect parts, skin cells, fibers and inorganic particulate.
