  2. Chromium Hexavalent • Chemical Composition: Fuming Liquid • Does not react with water at room temperature • Characteristics: • Gray, white, & brittle as a solid • Practically insoluble in water • Movement: • Enters the air, water and soil through natural processes and human activities (steel, leather, textile manufacturing & coal combustion) Most will eventually settle and end up in waters or soils.

  3. Chromium Hexavalent • Major Sources: Paints, Welding, Anticorrosion agents, photography, Volcanic dust & gas • Toxicity Level: Extremely toxic especially when inhaled • Environmental Damage: • Can contaminate water • Can cause soil acidification which damages crops • High concentrations can damage the gills of fish

  4. Chromium Hexavalent • Health Risk: Carcinogen • Skin rashes • Ulcers • Respiratory problems • Weak immune systems • Kidney and liver damage • Alteration of genetic material • Lung cancer
