| Popis: | The possibility of deriving normal biological values for some rare metals is investigated. The metals under study are gallium, germanium, indium, niobium and tellurium, i.e. a group of metals with increasing utilization in the electronics industry. So far some data are unavailable for some of the elements, e.g. daily intake, oral absorption and half-life time for gallium, and body burden for gallium and germanium. Reliable values of blood concentration are available only for gallium, niobium and tellurium. The problem related to a proposed urinary biological limit value for tellurium is also discussed. |
