“…Due to the presence of quartz in dust, the inhalation of the quartz particles in the size of 0.5-0.7 µm may produce diseases such as chronic silicosis, acute silicosis, accelerated 15 silicosis, and silica tuberculosis (Keramydas et al 2020, Ross et al 1993. Presence of quartz in the air might be a carcinogenic agent (Downward et al 2017, Keramydas et al 2020. The inhalation of hematite along with other substances in the dust might create lung disease.…”

The aim of this work is study of physical and chemical properties of dust of the Pre-Aral region of Uzbekistan such as Karakalpakstan and Khorezm that are located near the three deserts such as the Aralkum, Karakum, and Kyzylkum. The dust particles fell on glass have been collected in Karakalpakstan and Khorezm and studied systematically by employing wide range of methods. Particle volume vs size distribution has been measured with maximum around 600 nm and ~ 10 µm. The major and minor constituent materials present in the dust have been studied systematically by X-ray fluorescence spectroscopy, energy dispersive X-ray diffraction, and inductively coupled plasma optical emission spectroscopy. Main characteristic absorption bands corresponding to Si–O, Si–O-Si bonding in quartz and Fe–O bonds in hematite Fe2O3 have been identified by infrared and Raman spectroscopy. Quartz, hematite, lime, corundum, magnesia, and several other trace minerals have been identified in the dust particles. X-ray diffraction peaks corresponding to quartz, hematite, and corundum are sharp and are found to be more crystalline with some level of disorder. Analysis of the particle size and crystallinity on human being has been performed: disordered or crystalline quartz can create the lung disease; the particles in the size of 0.5–0.7 µm may produce diseases such as chronic silicosis, silicosis, and silica tuberculosis whereas hematite might create lung disease. Dust particles worsen optical transmittance of glass of the panels. Graphical abstract

“…In the same study, it was found that noise exposures to underground workers were independent of age which is similar to results obtained from this present study. In addition, Keramydas 26 reported in a similar study that the number of mine workers with hearing impairment increased exponentially with age until age 50, at which point 90% of miners had a hearing impairment, significantly associated with noise exposures above the PEL.…”

Background. Respirable dust, diesel particulate matter, crystalline silica and noise pollution are the most common causes of health issues experienced by underground mine workers. Assessment of exposure levels in relation to standard regulatory body permissible levels is essential for the safety of mine workers. Objectives. The present study compared exposure levels of diesel particulate matter, crystalline silica dust and noise experienced across different underground mine worker job titles. Methods. Subjective sampling was employed using gravimetric air samplers over an 8-hour time weighted average for two periods designated as period 1 (first half of the year) and period 2 (second half of the year). A comparative analysis of exposure levels between job titles and in relation to the National Institute for Occupational Safety and Health (NIOSH) permissible exposure levels (PELs) was performed. Results. In the present study, 90% of the selected job titles were over-exposed to noise and 80% were over-exposed to diesel particulate matter. The highest exposures for crystalline silica dust and diesel particulate matter were found in the 40–49-year-old age group. Conclusions. The present study of exposure levels of diesel particulate matter, respirable dust, crystalline silica, and noise during underground gold mining demonstrates that better control mechanisms are needed to protect workers.

Introduction: Occupational lung diseases are some of the common causes of lung function impairment. Spirometry is a gold standard to determine lung function and, to diagnose obstructive and restrictive lung diseases. Therefore, this study aimed to determine the prevalence of abnormal lung function among employees of different industries of Bhutan. Methods: This retrospective study was carried out by retrieving all the spirometry findings and demographic variables of employees of different industries of Bhutan from the Spirometry Software of Respiratory Laboratory at the Center for Research in Respiratory and Neuroscience (CRRN), Khesar Gyalpo University of Medical Sciences of Bhutan (KGUSMB) . All these retrieved data were saved in Microsoft Excel and simple descriptive statistics were used to analyze the data and were expressed in numbers, percentages, mean and standard deviation. Results: Spirometry and demographic results of 3508 industrial employees were obtained. The mean age was 33.8years and mean BMI was 24.95 Kg/m2. Non-smokers comprised 79.9% (2804) of the total industrial employees. Abnormal forced expiratory volume between 25% and 75% of vital capacity (FEF25%-75%), a marker of small airway disease, constituted 24.1% (846) of the total industrial employees. Furthermore, 1.1% (39) had abnormal forced vital capacity (FVC), 1.3% (46) presented abnormal forced expiratory volume in 1 second (FEV1 ) and 1.5% (53) showed reduced FEV1 /FVC. Conclusions: Small airway impairment is common among industrial workers of Bhutan indicating presence of high prevalence of occupational lung diseases in its early stage which may potentially become clinically apparent after long latency.
