“…The sampling site (Akrotiri monitoring station) is an urban background/marine monitoring station on the island of Crete (Greece), about 240 km from the Greek mainland (Athens) and 320 km from the northern African coast (Kopanakis et al 2012). A detailed description of Akrotiri station is given by Lazaridis et al (2008) and Kopanakis et al (2012).…”

“…However, only 14 of the 134 exceedances were due to African dust transport. The rest of the PM 2.5 exceedances can be attributed to local particle sources (Kopanakis et al 2012). In 2008 (PM 10 measurements, data coverage 89%) 67 exceedances of the daily limit (Table 2), 39 of which can be attributed to Sahara dust transport.…”

“…Half of those cases (37) were due to dust transport from the region of Sahara. During the period October-May (Table 2), almost all the daily PM 10 exceedances were due to African air-borne dust, unlike the period June-September, when the main reasons of PM 10 exceedances were associated with emissions from local sources (Kopanakis et al 2012). Table 3 shows the contribution of Saharan dust events to monthly exceedances of PM 10 concentrations in 2008 and 2010.…”

“…At Akrotiri station, several Sahara dust events were observed during the period -2009(Lazaridis et al 2008Kopanakis et al 2012 10 (50 μg/ m 3 ), the mean annual target value of EU and the daily limit of WHO guidelines for PM 2.5 (25 μg/m 3 ) were used. The Directive 2008/50/EC on ambient air quality and cleaner air for Europe provides Member States with the possibility to subtract the contribution of natural sources under certain conditions before comparing the ambient air pollutant concentrations to the limit values.…”

The eastern Mediterranean region is strongly influenced by long-range transported particulate matter such as desert dust from northern Africa. To investigate the dynamics of Saharan dust events and their origin, satellite images from the MODIS spectroradiometer of NASA's satellites Terra and Aqua, and back trajectories analysis of the HYSPLIT model were combined together with continuous ground-based field data. Field PM 10 and PM 2.5 measurements were performed in the period 2003-2013 at the Akrotiri monitoring station on the island of Crete (Greece). Furthermore, the mineralogical composition of a small number of samples was determined by X-ray powder diffraction, whereas elemental particle composition analysis was performed on the dust samples collected using the ICP-MS technique for a series of elements. The annual average percentage of days with Sahara dust outbreaks in the region of western Crete (Akrotiri station) was 9.3% for the period 2003-2013. Excluding the PM 10 exceedances caused by Sahara dust events, the average PM 10 monthly concentrations are decreased by 20.5% during the 8-month period November-June, with higher PM 10 concentration reduction (29.9%) in the period February-April. Mineralogical analysis showed that illite was the most abundant mineral identified in all samples, followed by quartz and calcite. Gypsum was detected only in the dry sample. Moreover, the elemental particle composition analysis showed that collected dust originated from Africa deserts.

Evaluation of the Dry Deposition of Particles Emitted by Biomass Combustion

et al. 2023

The dry deposition flux of particles smaller than 2.5 µm was investigated considering agricultural and urban regions. The concentrations, size distributions, and chemical characterization of particulate matter (PM) were evaluated and related to emission sources. The concentrations of fine PM were associated to the highest number of wildfire outbreaks. The results of the PM samples combined with the analyses of the air mass trajectories evidenced that the transport of this pollutant may have come from regions with industries that use biomass as fuel. The predominant water‐soluble ions in coarse and fine particulate were nitrate, potassium, calcium, magnesium, potassium, sulfate, and nitrate, respectively. The deposition fluxes of potassium, nitrate, and sulfate ions were higher during the sugarcane harvest than during the off‐season.
