This study looks at chronic oral exposure of hexavalent chromium in rats, and its association with cancer. The other study mentioned is a human health assessment of chromium, titled Toxicological Review of Hexavalent Chromium. The final human health assessment is currently in the stage of draft development. [47] This stage is the first of seven.
Chromium toxicity refers to any poisonous toxic effect in an organism or cell that results from exposure to specific forms of chromium—especially hexavalent chromium. [1] Hexavalent chromium and its compounds are toxic when inhaled or ingested. Trivalent chromium is a trace mineral that is essential to human nutrition.
PG&E used chromium 6, or hexavalent chromium (a cheap and efficient rust suppressor), in its compressor station for natural-gas transmission pipelines. [1] [3] Hexavalent-chromium compounds are genotoxic carcinogens. In 1993, legal clerk Erin Brockovich began an investigation into the health impacts of the contamination. A class-action lawsuit ...
Exposure to large amounts of hexavalent chromium is associated with lung cancer, according to a toxicological review of the substance by the Environmental Protection Agency, which evaluated ...
Hexavalent chromium, or Chromium-6, ... “Workers may be harmed from exposure to hexavalent chromium,” the CDC says on its website. “The level of exposure depends upon the dose, duration, and ...
Hexavalent chromium is a toxic metal, known to cause several health problems and is a carcinogen. Exposure to hexavalent chromium can cause irritation and problems in the respiratory tract, stomach, and small intestine. It is linked to several cancers, such as lung cancer, oral cancer, and intestinal cancer. [11]
Hexavalent chromium compounds can be toxic and carcinogenic (IARC Group 1). Inhaling particles of hexavalent chromium compounds can cause lung cancer. Also positive associations have been observed between exposure to chromium (VI) compounds and cancer of the nose and nasal sinuses. [11]
Hexavalent chromium compounds (including chromium trioxide, chromic acids, chromates, chlorochromates) are toxic and carcinogenic. Chromium trioxide and chromic acids are strong oxidizers and may react violently if mixed with easily oxidizable organic substances. Chromic acid burns are treated with a dilute sodium thiosulfate solution. [18]
