The lung function impairment is the most common respiratory problem in industrial plants and their vicinity. Therefore, the purpose was to study the affects of wood dust and its duration of exposure on lung function. This was a matched cross-sectional study of Spirometry in 46 non-smoking wood workers with age range 20 - 60 years, who worked without the benefit of wood dust control ventilation ...
A homogeneous batch of dew retted hackled flax was divided into two portions. One was untreated and the other was steamed for 45 minutes at 125 degrees C in three pressure/vacuum cycles in an autoclave. Dust was collected when the two flaxes were separately processed by industrial doubler and stapler machines. From untreated flax 7.2 g of dust was collected per kilogram of flax after two proces...
The Himalayan villages of Chuchot Shamma and Stok were surveyed because silicosis had been suspected from the radiographs of some of the inhabitants. The villages are agricultural, and Chuchot is exposed to frequent dust storms. Chest radiographs of villagers aged 50-62 were assessed blind by two independent observers using ILO criteria. In Chuchot five of seven men and all of the nine women ex...
This article summarizes issues associated with the vulcanizing systems used in latex product manufacture, including industrial hygiene (dust, packaging), zinc and nitrosamines. The allergy problems which appears to affect only dipped goods is briefly summarized by reviewing the treatments described in literature that might help minimize residual allergens. References are given on how to access ...

Zu§kin, E., and Valic, F. (1973). British Journal of Industrial Medicine, 30, 375-380. Respiratory response in simultaneous exposure to flax and hemp dust. The effect of exposure to high concentrations of mixtures of hemp and flax dust was studied in 124 workers in two textiie mills (mill A: 65-70% hemp and the rest flax, mean dust concentration 13 9 mg/m3; and mill B: about 35% hemp and the re...
Background and aims: Extensive industrial and production activities are one of the major sources of dust. In many cases, cyclones are used as the control measure. The removal efficiency of dust in cyclones depends on different factors. Some of these factors are, the design parameters, e.g. cyclone diameter, particle density, operating temperature and fluid physical properties, density of gas ...
In this paper we investigate the relationship between economic growth and industrial pollution emissions in China using data for 112 major cities between 2001 and 2004. Using disaggregated data we separate FDI inflows from Hong Kong, Macao and Taiwan from those of other foreign economies. We examine four industrial water pollution indicators (wastewater, chemical oxygen demand, hexavalent chrom...

The diagnosis of pneumoconiosis during life depends upon an industrial history and radiological examination (Carpenter, Cochrane, Gilson, and Higgins, 1956). However, many miners complain of dyspnoea but have no radiological changes at all. This has led to the supposition that long exposure to industrial dust hazards may lead to pulmonary disability which is not typical pneumoconiosis (Carpente...
