Dry separation of respirable lunar dust: Providing samples for the lunar airborne dust toxicity advisory group
In order to study the toxicity of lunar dust, the respirable size fraction of lunar soil needed to be separated with an apparatus that possesses the following capabilities: no use of liquid; fully recoverable sample; and use of only small sample quantities (o1 gm). We report the design of a simple apparatus that meets these requirements and implements an inertial-impaction mechanism established...
متن کاملDry Sliding Wear Behavior of Epoxy-Rubber Dust Composites
Composite pins of rubber dust collected from tyre retreading centres of trucks, cars and buses etc.and epoxy with weight percentages of 10. 15, and 20 % of rubber (weight fractions of 9, 13 and 17 % respectively) have been prepared in house with the help of a split wooden mould. The pins were tested in a pin-on-disc wear monitor to determine the co-efficient of friction and weight losses with v...

متن کاملChacinero's lung - hypersensitivity pneumonitis due to dry sausage dust.
OBJECTIVE Hypersensitivity pneumonitis (HP) comprises a large group of diseases that occur secondary to inhalation of a variety of antigens. This report describes a little-known cause of HP, previously unreported in the English literature. METHODS Five patients (three women) with a mean age of 41 years who fulfilled the criteria for HP due to exposure to dry sausage dust were studied. The cli...
متن کاملHuman Health Risk Assessment of Cadmium Exposure in Dry Deposition of Atmospheric Dust (Uncertainty Analysis)
Background and purpose: The atmospheric suspended particulate matter is a major route of human exposure to different kinds of environmental pollutants especially toxic heavy metals. The aim of this study was to assess the carcinogenic and non-carcinogenic risk of cadmium in dry deposition of atmospheric dust in Qazvin, Iran. Materials and methods: Glass traps were used for sampling dry atmosp...
