[1] Atmospheric desert dust is potentially highly sensitive to changes in climate, carbon dioxide and human land use. In this study we use 6 different scenarios of the processes responsible for changes in source areas and explore changes in desert dust loading in pre-industrial and future climates, although all the scenario results are likely to be sensitive to the climate model simulations use...

A pilot study was conducted within the Ontario sawmill and veneer/plywood manufacturing industry. Information was collected by postal questionnaire and observational walk-through surveys. Industrial hygiene walk-through surveys were conducted at 22 work sites, and measurements for wood dust, noise, and bioaerosol were taken. The aim of the study was to obtain data on the current status regardin...

BACKGROUND Wood dust has been classified as carcinogenic to humans and the association with nasal cancer risk has been observed in a large number of epidemiological studies. OBJECTIVES The aim of this study is to summarise data about occupational exposure levels to wood dust in Italy and to examine some exposure determinants. METHODS Exposure measurements on wood dust were extracted from th...

Introduction: Control of fugitative dust from mining process and application of an appropriate and economical system for dust collecting is essential. The goal of this study was cost-benefit analysis of an integrated systems and compare to bag filter in a crushing plant of a mining company. Methods: A local exhaust ventilation system for capture of emitted particlees, a water spray for dus...

Prevention and mitigation of acid rock drainage from mining are decisive for limiting environmental impact. Five by-products and industrial remnants (lime kiln dust, blast furnace slag, granulated blast furnace slag, cement kiln dust and fly ash) were investigated for their suitability to prevent acidity and metal(loid)s during leaching from highly sulfidic (50wt%, sulfide) waste rock in small ...
