Centro de Documentacion de Fundación MAPFRE - A Method for the determination of low concentration of organic vapours in air and exhaled breath

Notes: Sumario: A method is described for the determination of low concentrations of organic vapours in air and in exhaled breath. A measured volume is sample through a tube containing silica gel, then the vapour is desorbed with water in a closed tube and a sample of the head space air is taken for analysis by gas-liquid chromatography. The limit of sensitivity and maximal loading on the silica gel have been determined for benzene, n-butanol, acetone, hexane and trichloroethylene in street air and in the breath of non-occupationally exposed individualsRelated records: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 2, October 1977 ; p. 127-134Materia / lugar / evento: Higiene industrial Contaminantes químicos Contaminación atmosférica Control de la contaminación Benceno Acetona N-hexano Tricloroetileno Vapores orgánicos Técnicas cromatográficas Métodos de control Motores Fuel Otros autores: Lagesson, V.
