Preliminary results of size distribution airborne particles in Mexico city.
Particulate matter concentrations were measured in five size ranges, during an annual period, at the National University Campus in Mexico City.
Size distribution indicated high particulates values in the size ranges from 3.0 to >7.2 mum and from 0.49 to 1.5 mum.
The cascade impactor concentration represented 30% of the total suspended particles (TSP) values, with a correlation of 0.6 between them.
No significative seasonal difference in the mass particulate size distrubition was found, but in the rainy season a slight increase in fine particles with respect to the total mass impactor was found.
