Lung clearance, translocation, and acute toxicity of arsenic,

1985/4/1METHODS Oxides of arsenic, beryllium, cadmium, cobalt, lead, selenium, vanadium, and ytterbium were either purchased or prepared from solutions of soluble salts. They were administered to young adult rats via nose-only inhalation as a nonradioactive dry dust (BeO and PbO), or by intratracheal instillation of radiolabeled compounds in 0.9% saline (all others).

Beryllium

Beryllium has 4 electrons, 4 protons, and 5 neutrons.Beryllium has one of the highest melting points of the light metals: 1560 K (1287 C). It is added to other metals to make stronger alloys.Beryllium-copper alloy is used in tools because it does not make sparks.At standard temperature and pressure, beryllium resists oxidation when exposed to oxygen.
