fine dust sampling Articles

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • Dust collection dilemma: ostrich egg dust

    Rick Peil from the Toolking Superstore was presented with an interesting dust collection dilemma. Tamera Seevers creates unique fine art out of ostrich eggs (www.tameraseeversstudio.com). Carving and finishing the ostrich eggs takes up to three months and creates a very fine, ostrich egg dust. Her problem was with her 1-micron bag on the dust collection system, the dust was still escaping into ...

  • 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 ...

  • Your cell phone turns into dust

    For the sample preparation for the RoHS  analysis, several steps are necessary in order to achieve the desired degree of fineness. Optimal here are FRITSCH Mills.  Considering the characteristics of materials used for the construction of a cell phone the whole spectrum of hard-tough to hard-brittle up to soft, tough-elastic materials is found. Mentioned should be metals, ceramic parts ...

  • 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 ...

  • CaO–LOI classification system for cement kiln dust

    Cement Kiln Dust (CKD), a residual of cement production, has been used effectively as a cement replacement, but there is a lack of guidance for its appropriate selection and performance in specific engineering applications. Since CKD is not a controlled product, the chemical composition and material properties differ from source to source like coal fly ash. This paper presents a dual–letter ...

  • 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. ...

  • Study of mineral aerosols in fine (PM 2.5 ) and coarse (PM 10 ) atmospheric particles over a world heritage site at Agra, India

    PM 2.5 and PM 10 samples were collected at different sites from Agra to see their monthly and seasonal trends along with associated mineral aerosols. Annual mean mass concentrations of PM 2.5 and PM 10 over Agra were 104.25 and 261.89 µg/m 3 respectively. The monthly average varied from 26.94 to 211.56 µg/m 3 and 126.05 to 474.31 µg/m ...

  • Short-term variations in ambient particulates and their sources in Taichung, Taiwan

    Ambient particulate measurements were carried out using TE-PUF sampling and a Universal Air Sampler between 8 March and 25 April 2001 at Taichung. Samples were collected every 6 hours beginning at 0100 LST (Local Standard Time) each day at two sites, one at a university campus and the other at a roadside. Chemical species (Cl-, NO3-, ...

  • Traffic emission effects on ambient air pollution by PM2.5–related PAH in Upper Silesia, Poland

    The ambient concentration of particle–bound polycyclic aromatic hydrocarbons (PAHs) was investigated in two industrial towns in Upper Silesia, Poland. The 24 h samples of PM2.5 (particles with aerodynamic diameter ≤ 2.5 µm) were collected simultaneously at busy roads (or crossroads) and at an urban background site. Additionally, the samples were collected during the heaviest traffic density (rush ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • Welding Fumes and the effects of Manganese

    The potential risks of welding operations include the potential to breathe in metal fumes and toxic gases. Fume particles are formed from the vaporisation of molten metal that occurs during the process. These particles are very fine in size and may join together to form larger particles.. The biggest risk is exposure to the manganese contained in fumes that are given off during welding. ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...
