sb smelters, coal-fired plants, and refuse incinerator. In polluted areas containing high levels of antimony, it may be found in the air, water and soil. Antimony is a silvery-gray, lustrous metal. It is a moderate fire and explosion hazard in the forms of dust and vapor when exposed to heat and flame. Antimony can react violently with acids, halogens and oxidants. Short-term exposure to antimony can cause gastrointestinal pain, cough, loss of appetite, itching, skin eruptions, and irritation of the eyes, nose, and throat. ® The OSHA PEL is listed as 0.5 mg/m'. ■ The CaVOSHA PEL is listed as 0.5 mg/m'. ® The TLV is listed as 0.5 mg/m'. Exposure to antimony at high levels can result in a variety of adverse health effects. Breathing high levels for a long duration can irritateyou eyes and lungs and can cause heart and lung problems, stomach pain, diarrhea, vomiting, and stomach ulcers. In long-term studies, animals that breathed very low levels of antimony had eye irritation, hair loss, lung damage and heart problems. Problems with fertility were also noted. Ingesting large doses of antimony can cause vomiting. At this time, we don't know what other effects may be caused by ingesting it. In addition, antimony can irritate the skin if not removed. OSHA has set an occupational exposure limit of 0.5 milligrams of antimony per cubic meter of air J0.5 mg/m' for an 8-hour workday, 40-hour workweek. The ACGIH and NIOSH currently recommend the same guidelines for the workplace as OSHA. WARNING: Antimony is known to the State of California to cause cancer. Arsenic Arsenic is a naturally occurring element in the earth's crust. It is very widely distributed in the environment, and all humans are exposed to low levels of this element. The main use of arsenic is for pesticides. Some products, mostly weed killers, use organic arsenic as the active ingredient. Other pesticides use inorganic forms of arsenic to kill plants, insects or rodents or to preserve wood. Metallic arsenic is most commonly a gray, brittle, crystalline solid. It can also be in a black or yellow amorphous form. Arsenic is also commonly found in its volatile white trioxide form. Arsenic is used in several insecticides, herbicides, defoliants, desiccants, and rodenticides and appears in a variety of forms. It is also used in tanning, pigment production, glass manufacturing, wood preservation, and anti-fouling coatings. Arsenic enters the body principally through the mouth, either in food or in water. Most ingested arsenic is Quickly absorbed through the stomach and intestines and enters the bloodstream, although this varies somewhat for different forms of arsenic. Arsenic which is inhaled is also well-absorbed through the lungs into the blood stream.
