“…Also, the lung function parameters of FVC and FEV1 showed a significant decrease in each exposed group compared with the control group. This was consistent with findings by Isara et al [10] among workers exposed to quarry dust in Edo state, Nigeria and Draid et al on quarry industry workers in Libya [11]. The same results were obtained by similar studies [14][15][16].…”

“…They found out that chronic exposure to quarry dust is associated with respiratory symptoms and reduced lung function indices among quarry workers [10]. According to study by Draid et al on quarry industry workers, lung function tests of FVC, FEV1, and PEF were significantly changed in exposed workers [11].…”

Background -Workers in the mineral industries are exposed to airborne dust and its occupational exposure can cause respiratory disorders. The aim of this study was to determine the lung function and respiratory symptoms of workers exposed to mineral dust in the Eastern part of Iran. Material and Methods -This cross-sectional study was conducted on 156 workers in kaolin mine, gold mine, quarry, and stone cutting workshops as a dust exposed group and 48 administrative personnel in these sections as an unexposed group. After the general medical examination and completion of the demographic questionnaire, workers' pulmonary function test was performed for each person using a spirometer according to the American Thoracic Society standards. Finally, data analysis was performed using Tukey's post hoc and chisquared tests. Results -The mean age in the exposed group to dust and control group were 33.8±7.9 and 36.7±8.0 years (data are presented as mean with standard deviation), weight -75.1±13.0 and 75.0±11.2 kg, height -173.2±6.8 and 173.1±6.3 cm, and work experience -9.1±4.6 and 8.4±5.3 years, respectively. There was no significant difference between the working groups in the kaolin, gold, quarry, and stone cutting sections and the control group on the demographic variables. The mean value of the lung function parameters was lower in different working groups than in the control group. Significant differences were observed between the two groups in forced vital capacity and forced expiratory volume in 1 second parameters (P<0.05); however, there was no significant difference between them in peak expiratory flow and forced expiratory flow 25-75% (P>0.05). Conclusion -The results showed the exposed groups have significantly lower pulmonary function than the control group. Two out of four main pulmonary function variables showed reduce amounts in exposed groups.

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.

“…Exposure to quarry dust has been associated with deterioration in lung function among the quarry or mining workers [ 18 , 19 , 20 ]. Previous studies have shown that quarry and stone cutting workers had lower forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1 ), and FVC/FEV 1 compared to unexposed control groups, in China [ 21 ], Libya [ 19 ], and Palestine [ 5 , 6 ].…”

Environmental exposure to dust from quarrying activities could pose health dangers to the population living nearby. This study aimed to investigate the health effects of dust exposure on people living close to quarry sites and compared them with those who live far from the quarry sites. A cross-sectional comparative study was conducted among 79 exposed participants, who lived less than 500 m away from the quarry sites, and 79 control participants who lived more than 500 m away. All participants answered a questionnaire on dust exposure at home and health effects, as well as performed a lung function test in which both reported and measured health effects were investigated. People who live in close proximity to the quarry sites reported exposure to dust at home (98%), land destruction (85%), plant leaves covered with dust (97%), and an inability to grow crops (92%). The exposed group reported significantly higher eye and nasal allergy (22% vs. 3%), eye soreness (18% vs. 1%), and dryness (17% vs. 3%), chest tightness (9% vs. 1%), and chronic cough (11% vs. 0%) compared to the control group. Lung function parameters were significantly lower among the exposed group compared to the control group; mean forced vital capacity (FVC) was 3.35 L vs. 3.71 L (p = 0.001), mean forced expiratory volume in the first second (FEV1) was 2.78 L vs. 3.17 L (p = 0.001). Higher levels of airway restriction were found among the exposed group. Among the exposed group, lung function parameters worsened with the increasing closeness of home to the quarry site. This study demonstrates the negative health effects of environmental dust exposure among two communities living near quarry sites in Palestine. The results highlight the importance of developing and strictly enforcing rules and regulations in Palestine to protect population health.
