Explosion dust particle size measurements.
In situ measurements of the sizes and concentrations of dust particles generated by the detonation of high explosives in clay soil near Leesville, La., sandy clay soil near Huntsville, Ala., and sandy soils near Orogrande, N.M. are reported. Measurements were generally made within 1 m of the surface (in one case 10 m) at distances ranging from 10 to approximately 50 m from the detonation point ...
متن کاملDistribution of metals in particle size fractions from street dust of Murcia (Spain)
Many studies on concentration of heavy metals in street dusts have been conducted. However, the distribution of metals in the different particle size fractions, which compose the dust, has been much less studied. Some authors have showed the effect of particle size in heavy metal distribution and have indicated that concentration of metals in soils increases with decreasing particle size. Fine ...
متن کاملDistribution of pesticides and polycyclic aromatic hydrocarbons in house dust as a function of particle size.
House dust is a repository for environmental pollutants that may accumulate indoors from both internal and external sources over long periods of time. Dust and tracked-in soil accumulate most efficiently in carpets, and the pollutants associated with dust and soil may present an exposure risk to infants and toddlers, who spend significant portions of their time in contact with or in close proxi...
