| hazards summary | Boron is a compound that occurs in nature. It is often found combined with other substances to form compounds called borates. Common borate compounds include boric acid, salts of borates, and boron oxide. Several companies in the United States produce most of the world's borates by processing boron compounds. Borates are used mostly to produce glass. They are also used in fire retardants, leather tanning industries, cosmetics, photographic materials, soaps and cleaners, and for high-energy fuel. Some pesticides used for cockroach control and some wood preservatives also contain borates.Powder is a dust explosion hazard. Toxic by ingestion. May cause irritation, but not generally considered hazardous to handle boric acid and borates. Boron deficiency may cause reproductive injury in fish. Excess boric acid causes testicular damage in high-dose feeding studies of animals. Boron is a hepatotoxic agent. Minimal Risk Level (acute or intermediate oral dose) = 0.2 mg/kg/day (Develop.). Acute inhalation dose = 0.3 mg/m3 (Resp.). See Boric acid. |
| toxicity summary | IDENTIFICATION: . It is a naturally occurring element that is found in the form of borates in the oceans, sedimentary rocks, coal, shale, and some soils. Boron enters the environment mainly through the weathering of rocks, boric acid volatilization from seawater, and volcanic activity. Boron is also released from anthropogenic sources to a lesser extent. These sources include agricultural, refuse, and fuel wood burning, power generation using coal and oil, glass product manufacture, use of borates/perborates in the home and industry, borate mining/processing, leaching of treated wood/paper, and sewage/sludge disposal. HUMAN EXPOSURE: Only a few human studies have been conducted to assess health effects associated with exposure to boron compounds. The available data show that exposure is associated with short-term irritant effects on the upper respiratory tract, nasopharynx, and eye. These effects, however, appear to be short-term and reversible. The sole long-term follow-up study failed to identify any long-term health effects. No studies have been identified that assess reproductive outcomes. Based on the lack of human data and the limited animal data, boron is not classifiable as to its human carcinogenicity. ANIMAL STUDIES: Data regarding developmental and reproductive toxicity show that lower fetal body weight in rats is the critical effect. As dose level increases, the effects seen include: further rib effects and testicular pathology in the rat, decreased fetal body weight and increased fetal cardiovascular malformations in the rabbit, and severe testicular pathology in the rat; testicular atrophy and sterility in the rat; reduced fetal body weight in the mouse. Animal studies on mice and rats showed no evidence of carcinogenicity of boric acid. /Boron and Boron compounds/ |
