Source apportionment study based on selective wind direction sampling

The sampling technique may be a valid support in source apportionment studies. However, meteorological and territorial conditions could affect the results. The technique seems suitable for areas characterized by moderate winds and with two prevailing directions, as in the case of costal zones. The two sampled air masses monitored in this study often proved very similar, as far as the analyzed compounds are concerned. Results confirm that the study area does generally not seem characterized by a dominant source, as the incinerator, but by a widespread contamination due especially to vehicular traffic
