“…Neves et al, 39 in their study reported that adherence to PPE usage is determined by individual safety values and beliefs. Several studies have found that stone crushing is the main source of dust in stone quarries 16‐18 . This was observed in the quarries visited.…”

“…Quarry workers' distance away from the crusher (main dust source) and the use of required PPEs are important in determining the magnitude of dust exposure. Crushing is the most significant dust source in stone quarries and dust concentration decreases with increasing distance away from the crusher 16‐18 . Quarry workers are faced with varying concentrations of silica dust depending on the working location.…”

Background and aims Understanding the importance of using personal protective equipment (PPE) and the influence of work‐post (working distance to main dust source—crusher) in stone quarries is vital for designing tailored interventions in minimizing workers' exposure to silica dust. Nonetheless, studies on silica dust and disease symptoms in Ghana are nascent. This study assessed how work‐post and use of required PPE jointly influence exposure to silica dust and disease symptoms in Ghana. Methods Generalized linear models (complementary log‐log regression) were fitted to cross‐sectional survey data of 524 stone quarry workers in Ghana to assess the joint effect of work‐post and PPE usage on self‐reported disease symptoms while controlling for relevant compositional and contextual factors. Results Stone quarry workers who work between 1‐100 m and beyond 100 m from the crusher with the required PPE were 90% and 87% respectively less likely to report eye irritation compared with their counterparts who work between 1 and 100 m from the crusher without the required PPE. Individuals who work between 1‐100 m and beyond 100 m from the crusher with the required PPE were 94% and 95% respectively less likely to report breathing difficulty compared with the reference group. Workers who work between 1‐100 m and beyond 100 m from the crusher with the required PPE were 97% and 99% respectively less likely to report coughing compared with the reference group. Workers who work between 1‐100 m and beyond 100 m from the crusher with the required PPE were 93% and 97% respectively less likely to report common cold compared with their counterparts who work between 1 and 100 m from the crusher without the required PPE. Conclusion There are adverse health implications for people who work in silica dust polluted environments, suggesting the need for a national safety and health policy to target them.

“…Of the analysed studies, only one [43] was conducted in a construction-site environment; all other studies concerned mines or quarry sites. The exploited materials were, from the most commonly to least commonly exploited: coal [6,22,[30][31][32]41,44,52,56], iron [25,42], limestone [28,53], aggregates [24,51], taconite [47], granite [46], sandstone [55], copper [45], gold [48], platinum [54], and manganese [25].…”

“…Despite the experimental protocol of each paper, only 15 out of the 24 papers referred to dust-particle size [6,22,24,25,28,31,[43][44][45]48,49,51,52,55,56]. The remaining papers did not specify this parameter, despite mentioning "respirable dust" [41,47,53], "respirable and inhalable" [42,54], or just "dust" [32,50].…”

Occupational Exposure to Mineral Dust in Mining and Earthmoving Works: A Scoping Review

Anthropogenic activity is related to several environmental imbalances, including dust. Particulate matter can also hinder humans with numerous health consequences, such as asthma, cancer, and pneumoconiosis. With a particular focus on mineral dust, this review is intended to determine in which circumstances occupational exposure occurs in the mining and earthmoving industries. Research followed the guidelines provided by the preferred reporting items for systematic review and meta-analysis protocols and its extension for scoping reviews. Of the 8993 records identified, only 24 passed both exclusion and inclusion criteria. Within the pool of results, it was possible to identify the following variables related to dust exposure: job-related (activity, job category, and site), engineering (equipment, transport system), technical (distance), and physical (season and weather) variables. Due to the significant variance in protocol settings, it was challenging to perform a general analysis, resulting in a study-by-study approach. The most significant conclusion of this study is not related to the setting of occupational exposure, although it derives from it. The necessity of adopting standard procedures for data collection, independent of research objective, was demonstrated within the context of occupational exposure to mineral dust.

This study compares modelling results to measured concentrations near dust sources in a natural stone quarry and in two aggregate quarries. In the natural stone quarry, the dust source was drilling and in the aggregate quarries, it was crushing. Aim is to evaluate performance of model BREEZE AERMOD under 200 m from the dust source, and to estimate AERMOD’s applicability to represent short time dust dispersion events. If the model can capture the short-term variation of dust dispersion, it is usable in evaluation of weather conditions, when dust prevention should be enhanced, or production even paused, if there are critical objects near the quarry. The comparison between the measured and the modelled concentrations showed, that the model reacted more severely to changes in weather conditions, whereas the measurements showed no significant changes. AERMOD was not able to predict hourly concentration fluctuation, which is assumed to result from the lack of on-site meteorological data. The emission factors (EFs) determined for drilling either overestimated or underestimated the dust concentration. Therefore, the EF for drilling needs further research to obtain results reflecting the measured concentration levels better. The EF for crushing predicted well the dust dispersion near the dust source during the summer, but the model was unable to predict the dust concentration increase during the wintertime caused by the ground inversion, trapping the dust particles to remain near the ground. Modelling is applicable to aggregate quarries operating during unstable (non-inversion) meteorological conditions. Usage of on-site weather parameters is recommended.
