Air quality assessment in an industrial area by using environmental indicators

In the present work an assessment of the air quality in the Ptolemais - Kozani industrial area (Northwestern Greece) is attempted by the use of environmental indicators. Data about the air pollutant concentrations measured over this area through the years are used for the calculation of the Pollutant Standard Index (PSI). The spatial and temporal variation of the PSI is studied and the results are analysed in terms of air pollution daily levels in the area. Air quality comparisons among regions within the broader area of the basin under study are also given.
