Segregation of respirable dust for chemical and toxicological analyses
Archives of Environmental & Occupational Health, 2020Respirable dust can pass beyond ciliated airways of the respiratory tract and influence adverse health effects. Health effects can be studied using samples generated from bulk dust segregation. Because previous segregation methods diverge from size-selection criteria of the international convention for respirable particles (ICRP), a method was ...

Sampling for respirable cotton dust
Journal of the American Oil Chemists' Society, 1984AbstractThe nature of sampling from a dust cloud containing fine dust and lint fragments is reviewed. The definition of “respirable cotton dust” in the OSHA Cotton Dust Standard is compared and contrasted with the quantity measured by the NIOSH (Lumsden‐Lynch) vertical elutriator (VE) cotton dust sampler.

Damage to the human lung from breathing a dusty atmosphere is not new. Scientists who have studied Egyptian mummies have found cases of silicosis, a disease caused by damage to the lung from inhaling very fine particles of silica. These Egyptian incidents of silicosis probably were caused by the fact that it was common practice to create vases and ...

An Evaluation of Quartz as a Component of Respirable Coal Dust
Journal of Hazardous MaterialsThe rising cases of coal worker's pneumoconiosis since the early 2000s have driven research into respirable coal dust. Prolonged quartz dust exposure is deemed to be the primary cause of the resurgence in pneumoconiosis. This study examines how quartz present in coals of various ranks produces hydroxyl radicals (•OH), a reactive oxygen species linked ...

The cytotoxicity of respirable coal dusts
1994The pathogenesis of coal-workers pneumoconiosis has been related to three factors: total lung dust, rank of coal and the effect of quartz (Morgan et al, 1976,Parkes, 1982, Seaton, 1983), but the relative contribution of each constituent of the mineral dust remains incompletely understood as the incidence of disease in many collieries cannot be entirely

A new mass sensor for respirable dust measurement
American Industrial Hygiene Association Journal, 1975A new portable instrument measures mass concentration in the 100 mug/m3 range of airborne dust particles smaller than 10 mum. An electrostatic precipitator desposits particles as small as 0.01 mum onto a piezoelectric micro-balance sensor. The instrument utilizes digital readout and a built-in sensor cleaner.

An evaluation of pyrite as a component of respirable coal dust
Journal of Hazardous MaterialsOver the past two decades, the rise in coal worker's pneumoconiosis has prompted research into the effects of respirable coal dust components. This study explores how coal-pyrites produce hydroxyl radicals (•OH), a reactive oxygen species closely associated with particle toxicity, and assesses the ability of safe chemical additives to reduce •OH ...

Recent Developments of Dust Respirators in the United Kingdom
American Industrial Hygiene Association Journal, 1968Abstract Two significant developments concerning dust, respirators have occurred very recently in the United Kingdom. One development involves a half-mask facepiece with an inflated pneumatic face-sealing edge that fits human faces-as well as a conventional full facepiece.
