“…These functional changes suggested obstructive changes in airways and increased compliance. Neukirch et al 30' reported that lung function measurements, even after adjusting for age, weight and smoking habits, were significantly lower in the silica dust exposure group than in the control group, and that this was observed in both small and large airways.…”

The Effect of Silica Dust on Ventilatory Function of Foundry Workers: Jung Wan Koo, et al. Department of Preventive Medicine, College of Medicine, The Catholic University of Korea-In order to study the exposure level of silica dust and the effects of silica dust on ventilatory function, respirable dust samples were collected with personal air samplers by means of NIOSH method 0500 in selected foundry operations, and ventilatory function tests were performed on 209 male foundry workers and 239 male control subjects. The average quartz concentrations of respirable dust were the highest in melting (0.079 Mg/M3) and followed by molding (0.051 mg/m3), finishing (0.041 mg/m3) and coremaking (0.023 mg/m3) in descending order. No significant differences in mean values for all ventilatory indices expressed as a percentage of the predicted value were demonstrated between smokers and nonsmokers in foundry workers and control subjects. Mean values for all ventilatory indices except FVC in foundry workers were significantly lower than those in control subjects. Mean values for FEV,%, MMF, FEF25, FEF50 and FEF75 expressed as a percentage of the predicted value tended to decrease with increasing cumulative dust exposure. In foundry workers, proportions of workers with low MMF, FEF50 and FEF75 were noticeably higher than those for other indices, and were significantly increased with increasing cumulative dust exposure. With the above considerations in mind, it suggested that increasing exposure to silica dust be associated with progressive deterioration in ventilatory function of an obstructive nature and that MMF, FEF50 and FEF75 be sensitive indices in the detection of early obstructive changes in air flow of workers exposed to silica dust.

“…In other words, if we repeat this study in ten years our exposed group may show a significant drop in lung function grouping respect to controls. Lung function begins to drop at the age of 25 to 30 years, and tobacco smoke accompanied by exposure workplace reduces it further (25).…”

Tile workers are exposed to dust particles and are susceptible to multiple pulmonary complications. Problems like asthma, chronic obstructive pulmonary symptoms, and silicosis are more common among them. As there are many tile factories in Yazd, we decided to evaluate the respiratory symptoms and lung capacities in these workers and compare them with controls. This study included 176 tile and ceramic factory workers occupationally exposed to dust and 115 unexposed workers as controls. We recorded the respiratory symptoms using the British Medical Research Council questionnaire and measured lung capacities of the two groups. All study subjects were male, and the two groups were comparable in age and smoking. The exposed group had frequent respiratory symptoms and a significant relationship between them and duration of employment. In addition, lung capacities in ceramic workers with symptoms were lower than in workers without the symptoms. Even though the respiratory symptoms were more frequent in the exposed group than in controls, lung capacities of the two groups were similar.

“…Silica exposure in diVerent workforces, such as gold miners, granite crashers, and foundry workers, has been linked to reduced spirometric lung function that seems to be independent of silicosis (Hnizdo and Vallyathan 2003). However, only a few studies have been carried out on its eVects in tile or pottery workers (Forastiere et al 2002;Neukirch et al 1994).…”

This study provides evidence that long-term exposure to dust in tile industry is related to lung function reduction. There was a suggestion of synergistic effect between dust exposure and smoking. Tile factories should consider measures to reduce dust exposure and arrange spirometry surveillance for workers with such exposure. Smoking cessation should be promoted to prevent harmful effects of occupational tile dust exposure.
