  • The invisible fine dust

    Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous. According to a current study conducted by the Max Planck Society, ...

  • Down with road dust

    There are more than 3.9 million miles of roadway in the United States, according to the Federal Highway Administration, and, depending on the area of the country you're in, as much as 70% of that road mileage is unpaved. The 1997 U.S. Environmental Protection Agency (EPA) National Air Quality and Emissions Trends Report states that those unpaved roads--which can cover a wide range of ...

  • Reducing the risk of dust explosion hazards

    In the wake of recent tragic and highly publicized dust explosions, companies are asking, 'Could that happen here?' and 'What can I do to prevent such an incident at my facility?' One approach is to manage dust explosion hazards as though they were subject to OSHA’s Process Safety Management (PSM) requirements (29 CFR 1910.119), even though dust hazards often are not covered under this ...

  • Data Quality in Lead Dust Wipe Measurements

    Considerable investment has been made in studies to determine the usefulness of fieldportable XRF for the analysis of dust wipes on-site. With an estimated 38 million (40%) of housing units in the United States having Lead Based Paint ...

  • Global Model Simulations of the Transport of Asian and Sahara Dust: Total Deposition of Dust Mass in Japan

    Abstract  We simulated the global transport of dust emitted from all major dust source regions on earth by using a global three-dimensional chemical transport model for the year 2000. A modified dust emission flux scheme and an advanced nonlocal diffusion scheme for accurately determining the atmospheric eddy diffusivity in the atmospheric boundary layer were implemented to improve the ...


  • Assessment of cement’s dust impact on the soil using principal component analysis and GIS

    To evaluate the impact of the cement’s dust emitted by the eastern Moroccan cement factory (Oujda Holcim) and deposited on the soil of the Ain Lahjar commune, 58 samples of soil were collected around the factory on a radius of 3 km approximately. The physicochemical analyses of the upper 3 cm of the soil surface samples correspond to the pH, electrical conductivity, the chlorides and the oxides ...

  • Accumulation and distribution characteristics of platinum group elements in roadside dusts in Beijing, China

    The concentrations, distribution, and accumulation of platinum group elements (PGEs) were investigated in roadside dusts collected in four different foundational areas in Beijing during February to May 2010. The results showed that PGE levels in all samples were above the average upper crust values, with mean concentrations of 57.5 ng · g−1 Pd, 28.2 ng · g−1 Pt, and 9.8 ng · g−1 Rh, respectively. ...

  • How do typhoons and dust storms affect rainwater harvesting systems?

    This study aimed to investigate the effects of typhoons and dust storms on harvested rainwater quality. Rainwater samples were collected from the rainwater harvesting systems in northern Taiwan between September 2010 and April 2013. There were five typhoons and one dust storm that hit Taiwan during this period. Harvested rainwater was analyzed, including pH, electrical conductivity, turbidity, ...

  • Characterizing potential water quality impacts from soils treated with dust suppressants

    Received for publication April 24, 2008. Two separate laboratory experiment series, surface runoff and steady-state seepage, were performed to determine if dust suppressant products can be applied to soils with an expected minimal to no negative impact on water quality. The experiments were designed to mimic arid field conditions and used two soils (clayey and sandy) and six different dust ...

  • Portable lead analyzer to locate source of lead

    OBJECTIVE: To investigate the sources of lead in the environment in children with elevated blood, with the help of a Field Portable X-Ray ...

  • PureAire Oxygen Analyzer for 3D Printers: How Argon is used and Why O2 Detection is Required

    Thanks to new technologies, the 3D printers that have been used to create plastic three-dimensional objects can now print metal. Titanium 3D printing is possible thanks to a technique called DMLS, or Direct Metal Laser Sintering. While the potential to use titanium 3D printing is groundbreaking for many industries, the new advances could pose a health hazard if volatile gases used in the printing ...

  • Particulate matter effect on biometric and biochemical attributes of fruiting plants

    Dust accumulation capacity of Ficus carica L. and Psidium guajava L. was investigated from eight different sites of Multan, Pakistan.  Leaves of both plants were used for analyzing biometric (leaf area, fresh and dry weights) and biochemical attributes (chlorophyll contents, carotenoids and ascorbic acid).  Maximum dust accumulation was occurred in the plants growing near road sites, ...
