Summary Daily sampling of atmospheric PM10 particulate was carried out using a continuously weighing, Tapered Element Oscillating Microbalance (TEOM) equipped with a PM10 size selective inlet. The TEOM collects PM10 on a small filter interfaced with an inertial mass transducer, which allows near continuous weighing of the filter as the deposit accumulates. The sampler was sited at several urban and sub-urban places in Córdoba City, Argentina. With the complete data set of chemical and meteorological variables (CO, NOx, O3, wind speed, wind direction, ambient temperature, total and UV radiation, pressure and relative humidity, etc.) a stepwise regression was performed to select which variables have a major influence on the amount of PM10 measured. Results are presented from the June 1995–May 1996 field campaign. Data for PM10 values largely exceeded the one day standard average value of 150 μg m−3 during several days. The largest amount of particulate has been measured during the winter season. The primary aim of this work is to define the concentration characteristics of ambient PM10 at each site where this pollutant has been measured and to examine the seasonal variation of PM10.
