Resumen
The urban aerosol has been studied in general and there are few detailed analyzes that determine
the specific contribution of anthropogenic sources, we study ten industrial production process
located in Chihuahua, City. According to the permanent report by Air-Quality-Monitoring-
System about the particulate matter level from the city, it is close to the regulatory limit level and
missing information concerning the type of morphology and elemental composition of particles
size minor to 1.0 μm. The main goal of this study was to characterize the individual morphology
and elemental composition of anthropogenic particulate matter generated in this city. The
particles samples were collected during 2009 between June and August, the monitoring time was
around 20 minutes. We used Eight-Stage-Non-Viable-cascade-Impactor-Mark-II and selected
aerodynamic diameter 1.1μm for study in detailed. TEM-grid was placed at this stage to
collected sample; they were studied by transmission electron microscope model CM-200-
Philips® with elemental analysis system. The NIH ImageJ software was used for treatment and
analyses the acquired images. From 358 particles analyzed we determined mean values for
diameter of Feret (DF), compactness ratio (C), lacunarity (Lm and Lp), perimeter and density
fractal dimension (Dm and Dp). From data analyzed we can classify into four morphology types,
and they are spherical for polymeric, irregular shape for ceramic, cubic for metallic and
aggregates for fuel oil handling. The elemental composition is related with morphologies, we
find clearly typical morphologies categorically distinguishable.
