This paper reports an experimental investigation of the dust particle deposition process on solar photovoltaic (PV) modules with different surface temperatures by a heating plate to illustrate the effect of the temperature difference (thermophoresis) between the module surface and the surrounding air on the dust accumulation process under different operating temperatures. In general, if the tem...

Laboratory studies, numerical simulations, and desert field tests indicate that aeolian dust transport can generate atmospheric electricity via contact electrification or "triboelectricity." In convective structures such as dust devils and dust storms, grain stratification leads to macroscopic charge separations and gives rise to an overall electric dipole moment in the aeolian feature, similar...

Intensive swine production generates odorous emissions which flow from the buildings housing the animals. High ventilation rates bring in fresh air, remove heat and moisture and enhance pork productivity. Numerous compounds contribute to the uniquely offensive odors from swine facilities, including fatty acids, amines, aromatics and sulfur compounds. Dust particles, which originate predominantl...

OBJECTIVE This study was conducted to determine the dust mite fauna of houses in Bitlis and Muş provinces, the monthly value of mite numbers/g dust, as well as the impact of temperature, humidity and altitude on their numbers. METHODS Dust samples were collected monthly from May 2010 to April 2011 from six houses belonging to three settlements; two of the houses were located in Bitlis, while ...

[1] Dust storms originating in the Gobi desert and the surrounding areas critically impact weather, climate, and public health in China and neighboring Pacific Rim countries. In the decades between 1954 and 2007, reports of annual dust storm occurrences and the corresponding amount of total precipitation at 753 Chinese meteorological sites show a reduction in the occurrence and intensity of dus...

BACKGROUND Dust events have long been recognized to be associated with a higher mortality risk. However, no study has investigated how prolonged dust events affect the spatial variability of mortality across districts in a downwind city. METHODS In this study, we applied a spatial regression approach to estimate the district-level mortality during two extreme dust events in Hong Kong. We comp...

Salt dust in rump lake areas in arid regions has long been considered an extreme stressor for both native plants and crops. In recent years, research on the harmful effects of salt dust on native plants has been published by many scholars, but the effect on crops has been little studied. In this work, in order to determine the impact of salt dust storms on cotton, we simulated salt dust exposur...

BACKGROUND Exposure to traffic-related air pollution (TRAP) can adversely impact health but epidemiologic studies are limited in their abilities to assess long-term exposures and incorporate variability in indoor pollutant infiltration. METHODS In order to examine settled house dust levels of hopanes, engine lubricating oil byproducts found in vehicle exhaust, as a novel TRAP exposure measure...
