“…Previous studies reported that concentrations of deposited iron observed during Asian dust events were much higher than those observed during the nondust periods, while the difference between dust and nondust events in deposited nitrate and total phosphorus concentrations was not nearly as dramatic [Kang et al, 2009;Kim et al, 2009;Furutani et al, 2010;Onishi et al, 2015]. Therefore, in the WNP ecosystem (colimited by iron and nitrogen [Moore et al, 2002;Liu et al, 2004;Krishnamurthy et al, 2009]), it is expected that, along the transport pathways of spring Asian dust, OPP is temporarily enhanced through relief of iron stress that acts as a limiting factor for the phytoplankton growth under nondust conditions [Duce and Tindale, 1991 [Yuan and Zhang, 2006;Han et al, 2011].…”

As the western North Pacific Ocean is located downwind of the source regions for spring Asian dust, it is an ideal location for determining the response of open waters to these events. Spatial analysis of spring Asian dust events from source regions to the western North Pacific, using long‐term daily aerosol index data, revealed three different transport pathways supported by the westerly wind system: one passing across the northern East/Japan Sea (40°N–50°N), a second moving over the entire East/Japan Sea (35°N–55°N), and a third flowing predominantly over the Siberian continent (>50°N). Our results indicate that strong spring Asian dust events can increase ocean primary productivity by more than 70% (>2‐fold increase in chlorophyll‐a concentrations) compared to weak/nondust conditions. Therefore, attention should be paid to the recent downturn in the number of spring Asian dust events and to the response of primary production in the western North Pacific to this change.

“…High wind speed can also aggravate sand-dust pollution due to local dust blowing in Jeddah. High wind speed and high temperature, both increase turbulence and resuspension of the dust particles (Kim et al, 2009). In an arid region like Saudi Arabia, high wind speed with no rain for months, surrounding deserts and wind blowing into inhabited areas from the neighbouring desert lands lead to high concentrations of PM (PME, 2012; Munir et al, 2013).…”

Dust storm is a common phenomenonand, a severe environmental hazard in western Saudi Arabia. In this study, simultaneous measurement of PM 10 , PM 2.5 and PM 1.0 and elemental compositions analysis of PM 2.5 in Jeddah city during springtime (March 2012) dust storm (DS) and non-dust storm (non-DS) periods were carried out to investigate the impact of DS on the levels, characterization and elemental compositions of atmospheric particles. Results indicate that PM fractions concentrations were higher in DS environment compared to non-DS. The diurnal variation of PM fractions concentrations was uni-modal in non-DS environment and bimodal in DS. PM 1.0 /PM 10 , PM 2.5 /PM 10 and PM 2.5 /PM 2.5-10 ratios were relatively lower in DS, indicating that sand-dust events in spring carry much more coarse than fine particles to Jeddah. PM 10 , PM 2.5 and PM 1.0 in DS and PM 10 and PM 2.5 in non-DS might originate from similar sources. PM 10 , PM 2.5 , PM 1.0 in DS and PM 10 in non-DS were correlated negatively with relative humidity and positively with wind speed. PM 2.5 and PM 1.0 in non-DS were correlated positively with relative humidity and negatively with wind speed. The crustal elements accounted for 44.62 and 67.53% of the total concentrations of elements in non-DS and DS, respectively. The elements concentrations increased in DS, with highest DS/non-DS ratios for Ca, Si, Al and Fe. This indicates that the soil originating species contributed mainly in DS particles.The enrichment factors values and non-crustal fractions in both non-DS and DS indicate that the main sources of Na, Mg, Si, K, Ca, Ti, Cr, Mn, Fe, Rb and Sr are of a crustal type, whereas S, Cl, Co, Cu, Zn, Ga, As, Pb and Cd are anthropogenic. V and Ni in DS only are emitted from anthropogenic sources. The enrichment factors of these anthropogenic elements were lower in DS. They might originate mainly from local sources in Jeddah.

“…These are well documented anthropogenic elements and their enrichments are not surprising (Ho et al, 2003;Kim et al, 2009;Tecer et al, 2012). In order to distinguish the natural and anthropogenic sources of the enriched elements, enrichment factor (EF) diagrams which are the log-log plots of crustal enrichment factors of elements vs. Al concentrations were generated.…”

In this study, chemical composition of coarse (PM2.5-10) and fine (PM2.5) aerosols and their seasonal characteristics was used to investigate factors affecting seasonal variations in concentrations of species. Concentrations of 17 trace elements and SO4 2-were determined in coarse and fine aerosol samples collected at a high altitude (1115 m above sea level) site (Torul, 40°32'34"N 39°16'57"E) between March 2011 to November 2012 on the Eastern Black Sea region of Turkey. The samples were analyzed by energy dispersive x-ray fluorescence (EDXRF) using an Oxford ED-2000 Spectrometer. Measured concentrations varied between approximately 0.40 ± 0.7 ng m -3 for As and 2070 ± 1270 ng m -3 for SO4 2-. Soil-derived elements, Al, Si, K, Ca, Ti, V and Fe, had higher concentrations in the coarse fraction as expected. The results indicated that concentrations of elements showed well-defined seasonal variations. Crustal elements showed higher concentration in summer. Na, which is an element generally associated with sea salt had also higher concentrations in summer season, suggesting a strong crustal contribution to Na concentration at our station. Anthropogenic elements As, Zn, Pb and Cr had comparable concentrations in both seasons. Cu, Ni, and V, had higher concentrations in winter season due to sources close to sampling point. Crustal enrichment factors of Ni, Cu, Cr, As, Pb, Zn and SO4 2-varied between 12 for Ni and 800 for SO4 2-. Upper atmospheric flow climatology showed that most frequent flow direction was the sector between West and North, indicating the regions between these wind sectors are the potential source regions for the observed levels of species.
