V        HEALTH HAZARD INFORMATION



          Bismuth compounds and its salts can cause kidney damage. Although the degree of such damage is usually mild. Large

doses can be fatal. Industrially it is considered one of the less toxic of the heavy metals, although intoxication has occurred from its

use in medicine. The similarity between the pharmacologic and toxic behavior of Pb and Bi has been pointed out in the literature.

Like Pb, Bi may be liberated from tissue deposits during periods of acidosis. Serious and sometimes fatal poisoning may occur from

the injection of large doses into closed cavities and from extensive application to burns. Death of animals from bismuth nephritis

following injection of soluble salts occurs within several hours to 24 days, the time being generally inversely proportional to the dose,

and it appears to be in the order of 5 - 10 times higher than the dose by slow intravenous injection for rabbits. It is stated that the

administration of Bi should be stopped when gingivitis appears, for otherwise serious ulcerative stomatitis is likely to result. Other

toxic results may develop, such as malaise, albuminuria, diarrhea, skin reactions and sometimes serious exodermatitis. Industrial Bi

poisoning has not been reported although bismuth absorbed in industrial cases may complicate the diagnosis of plumbism, since the

dark line in the gums, which is often present in lead poisoning, is also produced by bismuth. All Bi compounds do not have equal

toxicity.



Treatment and Antidotes: Personnel showing some of the symptoms noted above which might indicate that they were absorbing too

much bismuth into the body should be removed from exposure as soon as possible. Get medical advice. Personnel should be

cautioned against careless handling of these materials.
