“…Junttila et al [41] and [48] gained also the highest PM10 mass concentrations varying from approximately 3000 µg/m 3 to almost 36,000 µg/m 3 . Olusegun et al [47] measured high PM10 concentrations near crushing, almost 11,000 µg/m 3 .…”

“…Measurements near (less than 50 m distance) the crusher or inside the aggregate quarry or at the aggregate quarry boundary at downwind direction (if direction reported) are considered to represent the source concentration for crushing. Finnish aggregate quarries had the highest TSP source mass concentrations on average from almost 30,000 to below 40,000 µg/m 3 [41,48]. In Iran, stone crushing produced TSP (total dust) and PM2.5 (respirable) almost 10,000 µg/m 3 and approximately 1200 µg/m 3 , respectively [49].…”

“…Majority of the studies which measured TSP and PM10 [e.g. 43,48,51] showed that the TSP concentration is approximately 2 to 4 times the concentration of PM10. Chakraborty et al [59] gained an emission factor for TSP which was ten times higher compared to the emission factor for PM10 reported by Aatos [6].…”

A review of dust emission dispersions in rock aggregate and natural stone quarries Fugitive dust constitutes one of the most severe environmental problems in quarries because it escapes capture. This review aims to provide overview of dust concentration caused by quarrying by synthesizing the current knowledge. The 25 studies explored here were conducted in open-pit quarries or mines. Three main dust sources surfaced from the studies: drilling, crushing and hauling. Analysis revealed a range of dust concentrations caused by different quarrying operations. Crushing was the most significant dust source, while drilling caused the highest variation. Dust concentration decrease was observed with increasing distance, but the retention was incoherent due to local dust sources.

“…In the literature, hornblende fibres have been described in dust collected at aggregate grinding sites [30], in soils associated with actinolite [31] without being classified as asbestiform or in the lungs of taconite miners [32]. Magnesio-ferri-hornblende has been described in hydrothermal veins [33].…”

Aggregates and rocks from quarries located in metropolitan France and New Caledonia, all likely to contain asbestiform amphiboles, were analysed by a routine laboratory (AD-LAB). Morphological observations were made using transmission electron microscopy and chemical analyses were obtained with energy dispersive X-ray spectroscopy. The chemical analyses obtained from amphiboles were treated in such a way that they could be plotted in a diagram (Si apfu versus Mg/Mg+Fe2+). The points corresponding to analysed particles, classified as asbestos, define a broader compositional domain than that corresponding to the compositional areas of actinolite and tremolite. The creation of two new domains is proposed. Samples of basic metavolcanics and amphibolites collected by the Geological and Mining Research Bureau (BRGM) in different quarries of the Armorican Massif and the Massif Central containing calcic amphibole fibres have been the subject of polarized light microscope and electron microprobe analyses. The representative points of the spot chemical analyses performed on the very fine and ultrafine fibres are contained in the range defined previously. The diagram that has been determined from chemical analyses coupled with morphological and dimensional observations can help the “routine laboratories” to better characterise asbestiform calcic amphiboles, but it also allows comparisons with geological observations.

“…Dust particles from quarry operations are observed to have elongated morphology (e.g. Junttila et al 1997 ;Hedges 2016 ). According to Räisänen ( 2004 ) the relative proportions of minerals in stone material are not the same as their proportions in the PM dust, whereas Belardi et al ( 2013 ) observed some correlation between size and morphology of particles and petrographic rock properties.…”

Dust mass concentration and concentration decrease was studied in two natural stone quarries in Finland. The dust mass concentrations produced during drilling was measured at several distances with short time interval (5 s) sampling. The variation of concentration was high, and wind direction had a crucial effect on dust dispersion. The impact of weather conditions, such as temperature and relative humidity, on dust concentration were inconsistent. The dust produced during drilling was mainly coarse-grained and it settled quickly. The background mass concentration was attained from 55 to 105 m at the downwind direction from the drill. The fine particle mass concentrations were low during the measurements. The fine particles originated mainly from other, remote, sources and from the machinery used in the quarries. Local dust sources, such as hauling, had a significant impact on dust mass concentrations 1,* 2 1 2 even inside the quarry. The drilling capacity effected on dust mass concentration near the drill, but the impact vanished quickly with increasing distance.
