“…The particulate matter (PM), which is of major concern for public health, was reported in the framework of a short campaign supported by the World Bank (1997) and also there were some studies on the chemical composition of aerosol samples (Caridi et al, 1989;Ozafrán et al, 1999;Bogo et al, 2003;Smichowski et al, 2004).…”

Air pollutant concentrations from a monitoring campaign in Buenos Aires City, Argentina, are used to investigate the relationships between ambient levels of ozone (O3), nitric oxide (NO) and nitrogen dioxide (NO2) as a function of NO(x) (= NO + NO2). This campaign undertaken by the electricity sector was aimed at elucidating the apportionment of thermal power plants to air quality deterioration. Concentrations of carbon monoxide (CO) and sulphur dioxide (SO2) were also registered. Photo stationary state (PSS) of the NO, NO2, O3 and peroxy radicals species has been analysed. The 'oxidant' level concept has been introduced, OX (= O3 + NO2), which varies with the level of NO(x). It is shown that this level is made up of NO(x)-independent and NO(x)-dependent contributions. The former is a regional contribution that equates the background O3 level, whereas the latter is a local contribution that correlates with the level of primary pollution. Furthermore, the anticorrelation between NO2 and O3 levels, which is a characteristic of the atmospheric photo stationary cycle has been verified. The analysis of the concentration of the primary pollutants CO and NO strongly suggests that the vehicle traffic is the principal source of them. Levels of continuous measurements of SO2 for Buenos Aires City are reported in this work as a complement of previously published results.

“…Regarding oxidants and O 3 the average concentrations were significantly greater for the industrial area than for the centric area. Caridi et al (1989) found out that typical concentration for Pb in the suburban areas was 0.3 g/m 3 and 3.9 g/m 3 in centric areas of the city. The average time of sampling is not specified.…”

“…PIXE experiments took place at the TAN-DAR Laboratory accelerator facility of the Comisión Nacional de Energía Atómica, Buenos Aires, Argentina, as it was done in previous works (for example, [23][24][25]). PIXE analysis was performed (on 19 filters of each fraction) by using heavy ions 16 O (7+ charge state) at 50 MeV energy.…”
