“…The conclusion of research concerning IAQ in steel rolling industry, performed by Al-Zboon et al [8], is that PM 10 and PM 2.5 exceeded the international standards at most of the measuring points. Furthermore, within the study related to IAQ in steel making industry, Al-Zboon and Forton [9] reported extremely high concentrations of PM 10 and PM 2.5 in the indoor air. According to research performed by Nazli et al [10], PM 2.5 is one of the most prominent pollutants that causes workers' complaints in the food industry.…”

Air cleaners are devices that an increasing number of people use to improve Indoor Air Quality (IAQ) in their homes and workplaces, especially in areas where the outdoor air is often excessively polluted. However, such devices, from small to large air flow capacities, are also widely used in the industries of developed countries to control and reduce the impact of the pollutants’ emission. This study deals with the analysis of experimental data regarding IAQ in a production hall with CNC machines in conditions of high concentration of emulsion vapors, focusing on the application of mobile industrial air cleaners, as independent and supplementary components of HVAC systems. Exper-imental data is obtained through measurements, conducted by two different methods using two different measuring instruments. Analyzed results show that the application of mobile industrial air cleaners can lead to significant in-crease of the number of production hall working hours, during which, according to U.S. Environmental Protection Agency (EPA), indoor air quality, according to PM2.5 (µg/m3), coincides with the “Moderate” air quality category, while it may also lead to occurrence of working hours during which indoor air quality, according to PM2.5 (µg/m3), coincides with the “Good” indoor air quality category. Furthermore, the application of mobile industrial air cleaners leads to the decrease of the indoor air concentration of particulate matter of all sizes in the range of PM0.3 to PM10. However, analysis also shows that the devices’ effectiveness in the PM concentration reduction is heavily dependent on the mobile air cleaners mutual position, as well as the time that has passed since their actuation.

“…Some researchers have reported the levels of PM 10 and PM 2.5 in the cement processes. A study reported the levels of PM 10-2.5 in cement mill (2.15, 0.03 mg m −3 , respectively), loading area (0.03, 0.02 mg m −3 , respectively), and crusher (0.25, 0.07 mg m −3 , respectively) [41]. Another researcher reported the level of PM 10-2.5 in the cement processes included cement mill (0.59, 0.87 mg m −3 , respectively), packing (0.51, 0.50 mg m −3 , respectively), and crusher (1.55, 1.80 mg m −3 , respectively) [42].…”

Air pollution associated with suspended particles has become a significant concern in Vietnam recently. The study aimed to (1) investigate dust sources; (2) measure concentration levels of Total Suspended Particulate (TSP), Particulate Matter (PM) fractions; (3) identify silica levels and the correlation with respirable particles at a cement grinding plant in Vietnam. A total of 312 samples (52 TSP, 160 PMs) at 13 processes were measured using the direct-reading dust meter. The silica composition was analyzed in a certified laboratory using the X-ray fluorescence (XRF) technique. SPSS version 26 for Window was used to analyze the data. The operations of the cement grinding plant created multiple dust sources from the jetty to the cement dispatch process. The TSP levels ranged 0.06–38.24 mg m−3, and 40.38 % (n = 21) TSP samples exceeded the Permissible Exposure Limit (PEL) for an 8-h working shift. Besides that, there was a wide range and significant concentration levels of PMs in the cement processes. The levels of PMs were PM1 (0.00–0.06 mg m−3), PM2.5 (0.01–0.83 mg m−3), PM4 (0.02–4.59 mg m−3), PM7 (0.03–16.94 mg m−3), and PM10 (0.04–26.85 mg m−3). The highest mean levels of PMs factions were measured at the pre-grinding process. The inefficient operation of the dust collector contributed a significant factor to the dust dispersion in this process. The silica’s mean (SD) composition in respirable dust was 20.4 % (0.86) and was not significantly different amongst the processes. There was a significant correlation between the levels of respirable dust and silica exposure in the cement grinding plant (r = 0.99). The improvement of indoor air quality is needed to prevent health effects on cement workers.

“…The initial symptoms of VOCs inhalation include discomfort of throat and nose, dyspnea headache, irritation of skin, fatigue, and dizziness. High dosage may lead to loss of coordination, and damage to liver, kidney, and the central nervous system (EPA, 2017;Al-Zboon and Forton, 2019). Since there are thousands of VOCs, no standards have been set, while there are standards for some compounds which health risks such as formaldehyde.…”

Indoor air quality has significant impacts on occupational health, workers' comfort and their productivity. The aim of this study was to assess indoor air quality in a rolling steel plant and to identify corrective measures that could help improve indoor air quality. Many air quality indicators, namely: CO, CO2, VOCs, NOx, SO2, O3, PM10 and PM2.5 were assessed as part of the study. The results obtained showed that higher concentrations of CO, VOCs, were found at the furnace area, while the rolling and quenching process area has the higher concentration of SO2 and CO2 respectively. PM10 and PM2.5 exceeded the international standards in most of the measuring points. Potential negative health effects are expected due to the high temperature and VOCs at the furnace area in addition to the high particulate matters level in all points. Hazard indices (HI) were found to be >1 for all sites indicating possible health risk mainly due to the particulate matter. The respiratory system is the most affected organ, followed by cardiovascular system, then the eye irritation. Based on the potential health risks identified, the paper concludes with some recommendations for protecting workers' health. These include setting local standards for indoor air quality, applying job rotation strategy, periodical medical checks, good ventilation and conducting further studies concerning long-term effect of indoor air quality on occupational health.
