Soil water and particle size distribution influence laboratory-generated PM10
Management of soils to reduce the amount of PM10 emitted during agricultural tillage operations is important for attainment of air quality standards in California's San Joaquin Valley (SJV). The purpose of this study was to improve and expand upon earlier work of predicting tillage-generated dust emissions based on soil properties. We focus on gravimetric soil water content (GWC) and soil textu...
متن کاملSoy aeroallergens in thoracic fraction particles (PM10).
BACKGROUND The aerodynamic diameter of biological particles determines their ability to penetrate the human respiratory system. OBJECTIVE To assess the content of allergens less than 10 pm in diameter in the particle fraction of airborne dust in order to improve control of exposure to harmful soybean aeroallergens. METHODS In this study, 98 pairs of particulate matter measuring less than 10...
متن کاملDevelopment and application of an inhalation bioaccessibility method (IBM) for lead in the PM10 size fraction of soil.
An approach for assessing the inhalation bioaccessibility of Pb in the PM10 size fraction is presented, using an in vitro simulated epithelial lung fluid to represent the extracellular environment of the lung. The developed inhalation bioaccessibility method (IBM) is applied to a range of urban surface soils and mining wastes obtained from Mitrovica, Kosovo, a site where impacts upon human heal...
متن کاملParticle-size distribution and packing fraction of geometric random packings.
This paper addresses the geometric random packing and void fraction of polydisperse particles. It is demonstrated that the bimodal packing can be transformed into a continuous particle-size distribution of the power law type. It follows that a maximum packing fraction of particles is obtained when the exponent (distribution modulus) of the power law function is zero, which is to say, the cumula...
متن کاملParticle Size Distribution Analyses of Agricultural Dusts and Report of True PM10 Concentrations
This study presents the results of the particle size distribution (PSD) analyses of dusts from two agricultural facilities using filters from collocated PM10 and total suspended particulates (TSP) samplers. Ideally, PM10 concentrations obtained using the PM10 sampler should be the same as those using the TSP sampler. However, it was observed from numerous sampling episodes that there exists a b...
