“…The P loaded into a separate factor and showed correlation only with Li. Principal component analysis of chemical composition data of Khamasen dust showed similar result because P also formed a separate factor in that case (Abed et al 2009). North Africa and the Eastern Mediterranean are well known to accumulate one of the most extensive phosphorite provinces in the world.…”

Elemental composition of dust deposited onto leaf surfaces was analysed in this study. Leaves of oleander (Nerium oleander L.) were collected for testing the environmental quality from Tripoli (Libya), Tajura (suburban of Tripoli) and Ghadames (remote area). Elemental analysis was carried out by ICP-OES. Principle component analysis (PCA) and enrichment factors were used for characterizing and estimating the level of the pollution. Samples from Tripoli were found to have higher contents of Pb, Zn, Cu in comparison with suburban (Tajura) and remote (Ghadames) areas. Our results demonstrated that the leaves of Nerium oleander were useful indicator to assessment of atmospheric deposition. Only limited information is available on environmental issues in Libya and the results reported here may contribute significantly to the assessment of the quality of the environment in this country.

“…Several studies in many countries attributed part of Pb pollution to airborne dust transported from other countries [32][33][34]. Accordingly, regional or continental transport of fine aerosols cannot be excluded as a source of Pb in Jeddah's atmosphere, particularly from countries with high atmospheric lead concentration (e.g., Egypt).…”

. The collected PM 2.5 -samples were analyzed by ICP-MS for determination of lead. The average atmospheric PM 2.5 concentration was 50.8 mg/m 3 . Atmospheric PM 2.5 -concentrations were higher than the 24-h U.S. National Ambient Air Quality Standards (NAAQS) in 14 sample events. The average lead concentration for all samples was 0.07326 mg/m 3 . Atmospheric lead concentration was dependent on the sampling location. Concentrations at the two southern locations were higher than at the two northern locations. Southern locations had higher lead concentrations due to very high traffic density, in addition to their proximity to industrial zone. In general, the results of this study show a considerable decrease in atmospheric lead concentration 7 years after phasing out leaded gasoline. The study recommends further studies to accurately determine the current sources of atmospheric lead.

“…This is a well-known feature in spring when Sharav cyclones along the African Mediterranean coast emit dust from the northeastern Sahara and transport these dust outbreaks to Saudi Arabia and the Middle East (e.g. Abed et al, 2009;Notaro et al, 2013). These track from west to east at speeds often greater than 10 m s −1 (e.g.…”

Abstract. The inter-annual variability of the dust aerosol presence over the Red Sea and the Persian Gulf is analysed over the period [2005][2006][2007][2008][2009][2010][2011][2012][2013][2014][2015]. Particular attention is paid to the variation in loading across the Red Sea, which has previously been shown to have a strong, seasonally dependent latitudinal gradient. Over the 11 years considered, the July mean 630 nm aerosol optical depth (AOD) derived from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) varies between 0.48 and 1.45 in the southern half of the Red Sea. In the north, the equivalent variation is between 0.22 and 0.66. The temporal and spatial pattern of variability captured by SEVIRI is also seen in AOD retrievals from the MODerate Imaging Spectroradiometer (MODIS), but there is a systematic offset between the two records. Comparisons of both sets of retrievals with ship-and land-based AERONET measurements show a high degree of correlation with biases of < 0.08. However, these comparisons typically only sample relatively low aerosol loadings. When both records are stratified by AOD retrievals from the Multi-angle Imaging SpectroRadiometer (MISR), opposing behaviour is revealed at high MISR AODs (> 1), with offsets of +0.19 for MODIS and −0.06 for SEVIRI. Similar behaviour is also seen over the Persian Gulf. Analysis of the scattering angles at which retrievals from the SEVIRI and MODIS measurements are typically performed in these regions suggests that assumptions concerning particle sphericity may be responsible for the differences seen.
