“…Particle size analyses were performed on the dust samples in a minimallydispersed condition with a Coulter Multisizer, using the method of McTainsh et al (1997). The Névé 2000 sample has a mean grain size of 36.1 Am, a mode of 40.9 Am, and a standard deviation of 24.5 Am.…”

“…In the present study, deposition velocities of different sized particles are estimated based on Sehmel (1980) and Chamberlain (1975), and the surface roughness is assumed to be 0.10 m (rangelands with low surface cover). The dust particle size distribution is based upon the analysis, by Coulter Multisizer (McTainsh et al, 1997), of a dust sample collected at 10 m height during a regional dust storm in 1995 at Diamantina National Park in the Channel Country of southwest Queensland.…”

Widespread drought and record maximum temperatures in eastern Australia produced a large dust storm on 23 October, 2002 which traversed a large proportion of eastern Australia and engulfed communities along a 2000 km stretch of coastline from south of Sydney (NSW) to north of Mackay (Queensland). This event provided an opportunity for a study of the impacts of rural dust upon the air quality of four Australian cities.A simple model is used to predict dust concentrations, dust deposition rates and particle size characteristics of the airborne dust in the cities. The total dust load of the plume was 3.35 to 4.85 million tones, and assuming a (conservative) plume height of 1500 m, 62-90% of this dust load was deposited in-transit to the coast. It is conservatively estimated that 3.5, 12.0, 2.1 and 1.7 kilotonnes of dust were deposited during the event in Sydney, Brisbane, Gladstone and Mackay, respectively. In the South East Queensland region, this deposition is equivalent to 40% of the total annual TSP emissions for the region.The event increased TSP, PM 10 and PM 2.5 concentrations and reduced the visibility beyond the health and amenity guidelines in the four cities. For example, the 24-h average PM 10 concentrations in Brisbane and Mackay, were 161 and 475 µg m −3 respectively, compared with the Australian national ambient air quality standard of 50 µg m −3 . The 24-h average PM 2.5 concentration in Brisbane was 42 µg m −3 , compared with the national advisory standard of 25 µg m −3 . These rural dusts significantly increased PM 10 /TSP ratios and decreased PM 2.5 /PM 10 ratios, indicating that most of the particles were between PM 2.5 and PM 10 .

Industrial metals are now ubiquitous within the atmosphere and their deposition represents a potential source of contamination to surficial environments. Few studies, however, have examined the environmental fate of atmospheric industrial metals within different surface environments. In this study, patterns of accumulation of atmospherically transported industrial metals were investigated within the surface environments of the Snowy Mountains, Australia. Metals, including Pb, Sb, Cr and Mo, were enriched in aerosols collected in the Snowy Mountains by 3.5-50 times pre-industrial concentrations. In sedimentary environments (soils, lakes and reservoirs) metals showed varying degrees of enrichment. Differences were attributed to the relative degree of atmospheric input, metal sensitivity to enrichment, catchment area and metal behaviour following deposition. In settings where atmospheric deposition dominated (ombrotrophic peat mires in the upper parts of catchments), metal enrichment patterns most closely resembled those in collected aerosols. However, even in these environments significant dilution (by 5-7 times) occurred. The most sensitive industrial metals (those with the lowest natural concentration; Cd, Ag, Sb and Mo) were enriched throughout the studied environments. However, in alpine tarn-lakes no other metals were enriched, due to the dilution of pollutantmetals by catchment derived sediment. In reservoirs, which were located lower within catchments, industrial metals exhibited more complex patterns. Particle reactive metals (e.g. Pb) displayed little enrichment, implying that they were retained up catchment, whereas more soluble metals (e.g., Cu and Zn) showed evidence of concentration. These same metals (Cu and Zn) were depleted in soils, implying that they are preferentially transported through catchments. Enrichment of other metals (e.g. Cd) varied between reservoirs as a function of contributing catchment area. Overall this study showed that the fate of atmospherically derived metals is complex, and depends upon metal behaviour and geomorphic processes operating at landscape scales.
