Variability in Dust Exposure in a Cement Factory in

21/04/2005 Exposure to cement dust has recently been associated with laryngeal cancer (Diertz et al., 2004) and respiratory cancer (Smailyte et al., 2004). A review of cement studies has indicated that cement workers might be exposed to dust levels ranging 11–230 mg m −3 for total dust and 2–46 mg m −3 for respirable dust (Fairhurst et al., 1997). However, previous studies in cement factories have not assessed the variability in exposure

Exposure to cement dust at a Portland cement factory and

After excluding all men with documented exposure to asbestos during employment in an asbestos cement factory no increased risk of overall cancer or respiratory cancer was found among cement workers compared with white collar workers from the local reference population, using a Cox regression model controlling for age and smoking habits. Relative risks were 0.5 (95% CI 0.1-1.5) and 1.0 (95% CI 0.4-2.6) for men with 1-20 and more than 20 years of exposure

Variability in total dust exposure in a cement factory.

Exposure assessment is a main component of epidemiologic studies and variability in exposure. This assessment is considered as a common approach for such phenomenon. A total of 129 dust samples were collected randomly from 197 personnel from a cement factory located in Ilam province, during 2009 in Iran. The between- and within-group components of variability were determined to assess the contrast in exposure level between the Similar Exposure

Cement dust exposure and acute lung function: A cross

14/04/2010 A few studies [ 4, 5] have suggested a relationship between exposure to cement dust and acute, respiratory symptoms and changes in lung function. In a cement factory in Ethiopia there was an association between respirable dust and peak expiratory flow recorded after shift [ 4 ].

Cement dust exposure and acute lung function: A cross

14/04/2010 This factory was selected because no previous study has been carried out to assess dust exposure and respiratory health effects at this location which was expected to be representative for the numerous cement factories still using older technology worldwide. The factory is located 500 km east of the capital, Addis Ababa. It was established in 1935, and production began in 1945. There has been

Consequences of cement dust exposure on pulmonary

Several health conditions are associated with cement dust exposure; obstructive and restrictive lung disorders are the most common consequences. The aims of this study were to assess the pulmonary function of cement factory workers and to determine the distribution of respiratory consequences resulting from dust inhalation. Methods. A cross‐sectional study with convenience sampling was

Variability in Dust Exposure in a Cement Factory in

In conclusion, this study has demonstrated that exposure to cement dust in the factory has considerable variability. The a priori grouping by eight OGs representing the work area was found to be an efficient grouping scheme with regard to high contrast in exposure level between the work areas, minimal attenuation of exposure–response slope and small SE of the slope. Workers in the crane

Exposure to cement dust at a Portland cement factory and the risk of cancer J?rgen Vestbo, Kim M Knudsen, Edith Raffn, Bente Korsgaard, Finn Vejlo Rasmussen Abstract The relation between exposure to cement dust and cancer was examined in a population of 546 cement workers and a reference population of 858 randomly sampled men of similar age and area of residence. In 1974 all men gave

Effect of exposure to dust on lung function of cement

Exposure to Portland cement dust has long been associated with the prevalence of respiratory symptoms and varying degrees of airway obstruction in man. Apart from respiratory diseases, it was also found to be the cause of lung and laryngeal cancer, gastrointestinal tumours and also dermatitis. This Effect of exposure to dust on lung function of cement factory workers Med J Malaysia. 2000

Human Health Risk due to Cement Dust Exposure

The concentrations of these elements in the lungs of the exposed rats increased with closeness to the cement factory and length of exposure (Table 2-5). For example, from Table 2,the level of calcium and silicon had increased from 8.51 and 0.000 mg kg -1 to 75.50 and 0.97 mg kg -1,respectively for rats placed at 250 m from the cement factory after 180 days.

Exposure: occupational exposure to cement production dust, and exposure measurements including information regarding how the measurements were obtained (individual or group). Outcome: respiratory symptoms, lung function indices, asthma, chronic bronchitis, COPD, pneumoconiosis, outcomes identified by analysis of induced sputum or fraction of exhaled nitric oxide (FeNO) measurements.
