Fugitive dust is generated along unpaved mine roads from intermitlent equipment traffic. Typically. the majority of such traffic consists of trucks hauling either mine product or waste from the surface mine pit andlor the processing plant. Fugitive dust generated along these unpaved mine roads includes particles of all sizes which become airborne. The potential hazards include the deleterious e...

A field study in a dark grey basalt quarry nearby Rome is presented. PM10 airborne concentration due to typical quarry operations was recorded during a period of two months. The aim of the work is testing the suitability of the laser light scattering method in measuring airborne dust concentration in such typical environmental conditions like those from quarrying operations. To the scope, two s...

Abstract Peat soil is one of the types available in Malaysia, which has a high compressibility and low shear strength. Thus, peat considered inappropriate to support construction site its natural state. Among methods suitable for stabilization using cement. However, quantity cement required quite large made this method not too environmentally friendly due carbon dioxide, CO 2 emission from prod...

AIMS To develop a job-exposure matrix (JEM) from personal and static respirable crystalline silica (RCS) measurements in UK industrial silica sand workers. METHODS A total of 2429 personal and 583 static RCS dust samples were collected using cyclone samplers at seven UK quarries between 1978 and 2000. These data were combined, and analysis of variance using general linear models was used to e...
