Particles longer than 5 ?m and with a length/diameter ratio >3 are defined as fibers. Asbestos or other fibers still identified in residential environments due to the emission from asbestos-used building materials. The respiratory system is primary route of asbestos exposure; under residence time, asbestos-related adverse health effects inevitable. Currently, have been replaced man-made vitreou...

asbestos applications were limited during past two decades in developed nations due to its debilitating health problems, while in developing countries it’s various usages continues. the main goals of present study were evaluation of asbestos concentrations in ambient outdoor and indoor air and occupational exposure, as well as exposure effects on pulmonary function. sampling procedure was ca...

As compared with other candidate carbon sequestration technologies, mineral carbonation offers the unique advantage of permanent disposal via geologically stable and environmentally benign carbonates. The primary challenge is the development of an economically viable process. Enhancing feedstock carbonation reactivity is key. Heat activation dramatically enhances aqueous serpentine carbonation ...

Given Australia’s significant and aged asbestos legacy, the long-term sustainability of effective accessible waste management is a national priority Asbestos National Strategic Plan. The current policy for managing hazardous via deep burial in landfill. Technological alternatives to approved landfill methods exist could be considered innovative sustainable additional options waste, where these ...

Mineral carbon dioxide sequestration binds carbon dioxide by reacting it with magnesium silicate minerals to form solid magnesium carbonates that are ready for disposal. Research onmineral sequestration has focused on enhancing process kinetics in aqueous processing schemes. High costs of these processes are associatedwithmineral processing, such as ultrafine grinding, or the consumption of aci...

The use of plasma arc technologies, especially in the treatment of hazardous wastes, is set to expand. The technology is intermediate within the waste management hierarchy and is characterised as an Advanced Conversion Technique (ACT) with Best Available Technique (BAT) attributes. Adoption is driven by the increasing stringency of environmental regulations, the requirement for efficient resour...

Asbestos-contaminated vermiculite attic insulation (VAI) produced from a mine near Libby, Montana, may be present in millions of homes along with other commercial asbestos-containing materials (ACM). The primary goal of the research described here was to develop and test procedures that would allow for the safe and effective weatherization of low-income homes with asbestos. The presence of asbe...

OBJECTIVES The aim of the study was to analyze the correlation between pulmonary concentrations of asbestos bodies and asbestos fibers and to characterize asbestos body counts from lung tissue of Finnish patients occupationally exposed and unexposed to asbestos. METHODS Ninety-nine surgically treated lung cancer patients were investigated. The number of asbestos bodies in iron-stained 5-micro...
