“…Such exposure levels appeared to be comparable or lower than those found in other countries. For example, the total ambient dust concentration of 0.33 mg/m 3 was reported among 68 bakers in Norway ( 28 ), whereas a concentration of 1.56 mg/m 3 was recorded from flourmills in Iran ( 29 ). Moreover, significantly higher levels of dust were evident for dough makers in comparison to those working in other areas of a mill factory ( 12 ) which is consistent with the findings of the present case study and was also reported elsewhere ( 11 , 30 , 31 ).…”

Occupational dust exposure can occur in various settings, including bakeries. A case study was conducted in an industrial bakery in Perth, Western Australia, to assess exposure to particulate dust concentration. The factory was separated into three production zones and an office area which represented as a control zone. Results indicated that bakery workers in the production zones were exposed to higher ambient dust particle concentrations compared to those from the office environment. Coarse particles (>10 μm in aerodynamic diameter) were the predominant particle size fraction measured in all studied areas with the highest median exposure level recorded in the dough room (0.181 mg/m3, interquartile range 0.283). High personal concentration of respirable particles was also measured in the dough room (median 2.26 mg/m3) which exceeded the recommended limit of 1.5 mg/m3 and was more than 50 times higher than the concentration recorded in the office (0.04 mg/m3). The variation in dust concentrations between production zones underlines the need of more knowledge about how aerosol fractions are distributed across the production process. The findings also suggest that bakery workers are exposed to high dust levels that may increase their risk of developing respiratory diseases and the decrease of present exposure levels is imperative.

“…[1,8,9] In previous studies, it was observed that the amount of serum antigen in the group exposed to flour dust has a significant difference comparing to control group. [10] Breathing flour dust can induce allergy and chronic respiratory problems like asthma. [11,12] The outbreak ORIGINAL ARTICLE of respiratory symptoms and chronic obstruction of the airways are observed in the workers exposed to heavy flour dust [13][14][15][16] and significant reduction of some pulmonary function parameters such as forced vital capacity (FVC), VC, forced expiratory volume in the first second (FEV 1 ), and peak expiratory flow rate (PEFR) is observed in the individuals exposed to dust.…”

Background and Aim: Flour dust is one of the allergens dust in the workplaces, and its occupational exposure can cause respiratory impairments. The aim of this study was to investigate respiratory and pulmonary function problems in flour mills workers exposure to flour dust. Materials and Methods: This cross-sectional study was carried out at 11 flour-producing factories in Iran. Study subjects were including to 286 males (176 male workers with current exposure to flour dust and 110 male unexposed employees). Determination of dust concentration was carried out with personal dust sampler at all production wards of studied industries. Respiratory symptoms were investigated with American Thoracic Society questionnaire. Lung function tests were done by a calibrated spirometer. The statistical analysis was performed by SPSS 18 software and t-test, Chi-square, linear, and logistic regressions. Results: Age and job tenure means of exposed group were 35.2 ± 8.6 and 11.9 ± 6.03 years, respectively. This result, for unexposed group, too was gained 35.3 ± 8.5 and 10.89 ± 6.5 years, respectively. Atmospheric concentrations of respirable and inhalable dust were 12.4 ± 2.41 and 33.26 ± 3.47 mg/m 3 , respectively. These results indicated that prevalence of respiratory symptoms in exposed subjects was significantly higher than non-exposed workers. Likewise, pulmonary function parameters were significantly lower in exposed than the reference group. Conclusions: The findings of this study showed that occupational exposure to flour dust could be a significant factor of the prevalence of respiratory symptoms and functional disorders of the pulmonary.

Many factors affect lung function capacity in textile industry workers. This research aims to determine the factors that affect the vital role of pulmonary spinning workers in the textile industry. This research used an analytic observational research design with a cross-sectional approach. The sampling technique used total sampling and getting the sample was 96 people, and measurement of lung vital capacity used spirometry. The Low Volume Sampler was applied to measure dust concentration, and the questionnaire was used to assess the individual characteristics. Bivariate analysis of the variables is the working environment dust, exercise habits, smoking behavior, and gender are significant. The result of multivariate analysis of dust is the most affecting to the lung vital capacity. In conclusion, dust concentrations are classified above the Threshold Limit Value (TLV), so the company should control the source of dust exposure.
