Measurement of polycyclic aromatic hydrocarbons and other pollutants

A single point study of atmospheric pollution has been carried out in Granada (Spain); suspended particulate matter, sulphur oxides, ammoniac, nitrogen dioxide and polycyclic aromatic hydrocarbons were determined. There were variations in relation to the month and the day of the week. The PAHs have been determined through HPLC, with a mobile phase of acetonitrile-water (75-25). The results of measurements of benzo(a)pyrene were between 1.006 and 0.485 micrograms m-3 in two different periods of sampling.
