ALGUNOS RESULTADOS SOBRE LA CONCENTRACION DE COMPUESTOS ORGANICOS SOLUBLES EN BENCENO EN EL AEROSOL ATMOSFERICO

Preliminary results about the organic fraction, soluble in benzene, of the atmospheric aerosol are presented. 29 air samples taken at Ciudad Universitaria (Mexico City), between July 79 and August 80, were analyzed. The results indicate a variation with naxiu concentrations during December and January, and minimum during June, July and August; the concentration distribution is log-normal with a geometrical mean of 7.12µg/m3 and standard geometrical deviation of 1.81 µg/m3.
