Sección: ArtículosTítulo: Toxicokinetics of hexavalent chromium in the rat after intratracheal administration of chromates of different solubilities / Peter C. Bragt and Ernst A. Van DuraAutor: Bragt, Peter C.Notas: Sumario: The kinetics of chromium in the rat after a single intratracheal dose of sodium, zinc or lead Cr-chromate have been investigated. Sodium chromate and the less soluble zinc chromate were absorbed into de blood and this resulted in increased excretion of chromium into the urine. The insoluble lead chromate was poorly absorbed from the lungs. The more insoluble a chromate was in water, the higher its elimination via the feces. With all three chromates, absorbed chromium was retained in the spleen and the bone marrow. After de administration of sodium chromate, chromium was also retained in the liver and kidneys. On the basis of the minor resorption of lead chromate, it is concluded that chromium levels in blood and urine are not indicative of exposure to soluble chromates via the inhalatory routeRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 3, 1983 ; p. 315-322Materia / lugar / evento: Higiene industrialContaminantes químicosCromoCromatosToxicologíaMedicina laboralExperimentosOtros autores: Dura, Ernst A. van Títulos secundarios: Título: The Annals of occupational hygiene Otras clasificaciones: 872Derechos: In Copyright (InC)
