Ultrafine and respirable particles in an automotive grey iron foundry.

Relationships among particle number, surface area, and respirable mass concentrations in automotive engine manufacturing.

This study investigated the relationships between particle number, surface area, and respirable mass concentration measured simultaneously in a foundry and an automotive engine machining and assembly center. Aerosol concentrations were measured throughout each plant with a condensation particle counter for number concentration, a diffusion charger for active surface area concentration, and an o...

Exposure to respirable dust and cardiovascular disease mortality among Swedish iron foundry workers

ارزیابی میزان مواجهه کارگران با ذرات سیلیس بلوری در کارگاه‌های استان مازندران

Abstract Background and purpose: Workers' exposure to respirable silica particles especially free crystalline silica in workplace could result in some dangerous diseases such as silicosis or lung fibrosis. This study was carried out to evaluate the workers' exposure to free crystalline silica particles in some industries using the infrared spectrophotometery method. Materials and methods: I...

Ultrafine particle exposure during fire suppression--is it an important contributory factor for coronary heart disease in firefighters?

OBJECTIVE Coronary heart disease (CHD) is the primary cause of death among US firefighters during fire suppression. In other populations, exposure to respirable particles, including ultrafine particles, has been widely implicated as a risk factor for CHD. This study is the first to report detailed characterization of respirable particles released by combustion of an automobile and model residen...

Dust exposure and impairment of lung function at a small iron foundry in a rapidly developing country.

OBJECTIVES A cross sectional prospective study was carried out among iron foundry workers (exposed) and soft drink bottling and supply company workers (unexposed) to assess their occupational exposure to ambient respiratory dust in their work environment and its effect on their lung function profile. PARTICIPANTS Lung function was measured in 81 exposed and 113 unexposed workers. Personal res...
