Aerosols – Dusts, Fumes and Mists
ثبت نشده
چکیده
Instead of the definitions for total dust and fine dust which were used in the past, from 1996 the new internationally agreed conventions for measuring concentrations of particles (DIN EN 481, 1993) are to be used in the establishment of MAK values. Therefore the definitions of particle fractions and the methods of measuring them have been modified in line with this convention and also extended to apply to all aerosols, that is, not only to dusts but also to fumes and mist.

Respiratory Diseases Among Dust Exposed Workers
Airborne contaminants occur in the gaseous form (gases and vapours) or as aerosols. Aerosols may exist in the form of airborne dusts, sprays, mists, smokes and fumes. In the occupational setting, all these forms may be important because they relate to a wide range of occupational diseases. Airborne dusts are of particular concern because they are well known to be associated with classical wides...

Purpose To investigate associations between occupational inhalation risks and fractional exhaled nitric oxide (FeNO) levels in patients with chronic obstructive pulmonary disease (COPD). Patients and methods Data of 16,486 subjects who had undergone spirometry with pre-bronchodilator and post-bronchodilator lung function assessment were retrieved from the National Health and Nutrition Examina...
متن کاملOccupational exposures estimated by means of job exposure matrices in relation to lung function in the PAARC survey.
OBJECTIVES The aim of this analysis of the French Cooperative PAARC (Pollution Atmosphérique et Affections Respiratoires Chroniques) survey, was to test whether occupational exposures to dusts, gases, or chemical fumes or to specific hazards, estimated by job exposure matrices, were related to a decrease in forced expiratory volume in one second (FEV1). METHODS The most recent occupation was ...
متن کاملStatement of Evidence Health effects arising from inhalation exposure to welding fume Summary Under HSE’s wide-ranging initiative to bring about a reduction in occupational disease arising from exposure to dusts, gases, vapours and fumes, welders
Under HSE’s wide-ranging initiative to bring about a reduction in occupational disease arising from exposure to dusts, gases, vapours and fumes, welders have been identified as an ‘at risk’ group. The initial stage in this process is to identify and set out the underlying evidence base for the potential ill-health effects arising from inhalation exposure. Hence, the purpose of this paper is to ...
