11 Toxicological information
• Primary irritant effect: • On the skin: Irritant to skin and mucous membranes. • On the eye: Irritating effect. • Sensitisation: No sensitising effects known. • Subacute to chronic toxicity:
Large amounts of lithium compounds may cause vomiting, diarrhea, ataxia, intestinal irritation, kidney injury, central nervous system depression and a drop in blood pressure. Central nervous system effects may include slurred speech, blurred vision, dizziness, sensory loss, convulsions and stupor. Chronic intake may cause neuromuscular effects such as tremor, ataxia, weakness, clonus and hyperactive reflexes. Lithium can cause kidney damage, gastrointestinal disturbances, fatigue, dehydration, weight loss, dermatological effects and thyroid damage. Lithium ion has shown teratogenic effects in rats and mice. Lithium carbonate LD50 oral rat is 525mg/kg.
Boron affects the central nervous system. Boron poisoning causes depression of the circulation, persistent vomiting and diarrhea, followed by profound shock and coma. The temperature may become subnormal and a scarlatina form rash may cover the entire body.
If small amounts of boron (4.1mg.cu metre) are inhaled it can cause irritation to the nose, throat and eyes. The Occupational Safety and health Administration (OHSHA) has set an exposure limit of 10 mg/cu metre for boron oxide and sodium tetraborate in the workplace air for 8 hour/day exposures over a 40 hour week. Lethal effects: Human studies have shown that boron can be lethal following short-term exposure. The minimal lethal dose of ingested boron (as boric acid) was reported to be 2 – 3 g in infants, 5 – 6 g in children and 15 – 20 g in adults (Locatelli et al. 1987; Wong et al. 1964). There appears to be a differential susceptibility with regard to death in adults. It has been postulated that increased competence of the adult kidney accounts for increased adult tolerance to boron. Hepatic effects; Acute oral exposure in humans caused congestion, fatty changes, and parenchymatous degeneration (Wong et al. 1964). It is not clear how boron affects the liver, however, limited animal data suggest impaired electron transfer and macrometabolism. Reproductive effects: Male workers exposed to borate aerosols during the production of boric acid revealed low sperm counts in 6 out of 28 workers (Tarasenko et al. 1972). Summary:
Information exists on the adverse health effects of boron compounds in humans. Studies of workers exposed to boron compounds demonstrated that boron can cause mild irritation of the eyes and respiratory tract ( Garabrant et al. 1984, 1985 ). Other human studies involve case reports of accidental or intentional ingestion of large quantities of boron compounds ( Litovitz et al. 1988; Locatelli et al. 1987). The studies identified key health effects ( lung, kidney, brain, and liver) associated with boron exposure (Wong et al. 1984). Animal studies of the birth rate of occupationally exposed workers is currently underway at a major U.S. borate production facility. References for boron:

To the best of our knowledge the acute and chronic toxicity of this substance is not fully known. No classification data on carcinogenic properties of this material is available from the EPA, IARC, NTP, OSHA or ACGIH.
