“…higher EF, but it is known that Alicante soil is Ca enriched [36,37]. For example, EF were: Al 1.2, Ca 21, Ti 2.1, Fe 2.8 Sr 13.2 during normal period; during mascletà we obtain Al 28, Ca 31, Ti 5.9, Fe 2.4, Sr 126.…”

h i g h l i g h t sStreaker/Dekati/PIXE are suitable to study high-intensity short-lived firework events. Fireworks related elements showed >80% elemental mass in the submicrometric region. Resuspended soil dust is an important source of atmospheric particles in these shows. a r t i c l e i n f o b s t r a c tTypical of festivals in Eastern Spain, mascletàs are high-intensity pyrotechnic events where thousands of firecrackers are burnt in an intense, rapid episode that generates short-lived heavy aerosol clouds. High temporal resolution and size distribution characterisation of aerosol components were performed to evaluate the effects of the brief (<30 min) and acute exposure on the spectators present. Very high concentrations of firework specific elements, especially in the fine fraction, were reached during mascletàs, with values of about 500 g/m 3 for K and 300 g/m 3 for Cl. Sr, Al, Mg, Ba, Cu, Co, Zn, and Pb concentration increase factors of more than 100 (1000 for Sr and Ba) were observed in the fine fraction with respect to background levels. Crustal origin elements, like Ca, Fe, Si, Ti, also showed an important concentration rise (∼10 times above background levels) but this is due to dust resuspension by pyrotechnic explosions. The crustal components are mainly in the coarse mode (>90% elemental mass), between 2 and 3 m. Most firework related metals are concentrated in the submicrometric region (>80%) with a trimodal size distribution. This may be interesting to epidemiologists given the toxic effects that such fine, metal-rich particles can have on human health.

“…Moreover, meteorological factors that affect pollutant emissions and transformation processes could also account for the observed seasonal variation. Greater SO 4 2− levels during summer have also been observed in nearby urban and suburban areas as a result of increased photochemical oxidation of SO 2 (Galindo et al, 2011b;Yubero et al, 2015). However, the seasonal variation of carbonaceous species at Mt.…”

From February 2011 to September 2012, PM 1 samples were collected at the regional background station of Mt. Aitana, located near the eastern coast of the Iberian Peninsula at 1558 m a.s.l. Samples were subsequently analyzed to determine the major chemical composition (elemental and organic carbon, secondary inorganic ions and oxalate). The seasonal patterns of the concentrations of PM 1 and its main components and the influence of long-range transport of dust from the Sahara desert were studied in this work. PM 1 was mainly composed of organic matter and ammonium sulfate, while EC and nitrate were minor components. Concentrations ranged from 3.4 µg m -3 in winter to 5.8 µg m -3 during summer. This seasonal cycle is typical of high mountain sites, which are generally above the planetary boundary layer during winter time. All the analyzed components exhibited the same seasonal pattern except nitrate, which showed minimum values in summer. This is most likely the result of the decomposition of NH 4 NO 3 favored by the higher summer temperatures. Due to the close proximity to the African continent, PM 1 levels significantly increased during Saharan dust intrusions. The concentrations of sulfate were 35% higher during dust events since the formation of secondary ammonium sulfate is favored by heterogeneous reactions on the surface of mineral particles.

“…Major inorganic water-soluble ions are associated with the degradation atmospheric visibility (Cheng et al, 2011), adverse human health effects (Karthikeyan et al, 2006) and acidity of precipitation (Kerminen et al, 2001;Soo et al, 2011). Inorganic ions can arise from both natural and anthropogenic sources such as oceans, dust storms, biomass combustion, construction, road traffic, industrial activities or even indoor activities and have been commonly used for the identification of PM sources (Hu et al, 2008;Khan et al, 2010;Deshmukh et al, 2011;Galindo et al, 2011;Zhang et al, 2011).…”

Ambient PM 2.5 was sampled in three indoor environments (a common office, a photocopy room and a student dormitory) and one outdoor environment (a rooftop) on a campus of Nanchang University in Nanchang city, China, on June 5-20, 2009. Analysis by ion chromatograph showed the indoor-outdoor differences and relationships of water-soluble ions. The indooroutdoor distributions indicated that chemicals and household garbage contributed most to the generation of water-soluble ions indoors. The indoor-outdoor relationships of water-soluble ions in PM 2.5 in the common office and student dormitory were unrelated or weak, which indicated that the ions were produced indoors rather than carried in from outdoors. Correlations between various water-soluble ions in indoor and outdoor PM 2.5 are discussed here, and it is suggested that the photocopier machine contributed little to the water-soluble ions indoors. Ion balance calculations indicated that the anions and cations in the photocopy room and outdoor environment shared an origin, but part of the anions and cations in the common office room and student dormitory originated indoors. The linear regression slopes (anion/cation) are all lower than 1, with the anion deficits probably affected by the absence of data on F
