Toxicology Litigation Support
Hexavalent chromium exists in many forms among which are strontium chromate, lead chromate, zinc chromate, barium chromate, and calcium chromate, all of which are considered to be known human carcinogens. Welding of stainless steel is known to produce hexavalent chromium in the resulting fumes. The major target organ for hexavalent chromium compounds is the lung. The published literature is abundant with results of epidemiology studies describing the inhalation of hexavalent chromium compounds resulting in statistically significantly elevated risks for lung cancer. Most of these studies are described in chromate workers, but other studies show elevated risks of lung cancer in pigment workers and painters exposed to hexavalent chromium pigments. Also well described in the literature are studies which report hexavalent chromium as a mutagen and animal carcinogen. Clearly, the elements necessary to prove a causal connection between hexavalent chromium and lung cancer are easily found in the peer-reviewed literature. Aside from its carcinogenicity, hexavalent chromium is an allergen described as producing allergic contact dermatitis and upper respiratory sensitization including asthma. There are over 640 references in our hexavalent chromium database. Other toxic effects may be found in the selected references below.
