| Zusammenfassung |
| Herewith, we present an extended time-series of seventeen years of particulate matter (PM10)
observations conducted at the background Agia Marina monitoring station in Cyprus (EMEP,
532m a.s.l). The above time series has been analyzed on a multiannual, annual and
diurnal basis to extract novel information on the contribution of the natural and
anthropogenic PM sources influencing the ambient air in Cyprus and the Eastern
Mediterranean Area. The analysis showed that the mean levels of PM10 at Agia Marina
(29.6±10.1 ug m-3: 1996-2012) are comparable to the ones reported for the Finokalia
background station in Greece (28±30ug m-3: 2000-2005) and the rural Erdemli station in
Turkey (36±28ug m-3: 2000-2001) suggesting a common regional influence on
the observed levels. Additional PM2.5 observations during the 2010-2012 period
showed that the coarse particles comprise a large fraction (40-50% depending on the
respective season) of the total PM10 particles as depicted from the ratio PM2.5 to
PM10. Noteworthy, the statistical analysis of the deseasonalized annual PM10 data
revealed a significant decreasing trend of ~0.6ug m-3 y-1 (Mann-Kendall, a50ug m-3). However,
when taking into account the regional influence of the transported air massed on the
daily PM10 levels by subtracting the background levels of Agia Marina station, the
respective number of the computed exceedances becomes significantly lower (8%). |
