road dust control Articles

  • 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 ...

  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • 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, ...

  • Acute effects of road salts and associated cyanide compounds on the early life stages of the Unionid mussel Villosa iris

    The toxicity of cyanide to the early life stages of freshwater mussels (order Unionida) has remained unexplored. Cyanide is known to be acutely toxic to other aquatic organisms. Cyanide‐containing compounds, such as sodium ferrocyanide and ferric ferrocyanide, are commonly added to road deicing salts as anticaking agents. The purpose of the present study was to assess the acute toxicity of three ...

  • Features of machines used for hospital infection control

    Hospital infection control requires recourse to a good quality equipment that not only removes dirt but also eliminates molds, bedbugs, allergens, and germs. Healthcare services are grappling the problem of maintaining sanitization on a daily basis, and one of the most useful tools in this regard is a dry vapor system. A dry vapor system built for hospital infection control should have the ...

  • Cypher Environmental Ltd. Environmentally Friendly Soil Stabilizer Introduced to the Dominican Republic

    Building effective and long lasting roads in the Dominican Republic has proven to be difficult in the past due to high annual rainfall, high temperatures and the soil type predominantly found on the island. Recently a demonstration was performed on a stretch of road at the Naco Golf & Country Club near Santo Domingo with EarthZyme, a 100% environmentally friendly soil stabilizer that is ...

  • A quantitative approach to the traffic air quality problem: the traffic air quality index

    The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...

  • Evaluation of street sweeping and washing to reduce ambient PM10

    This paper presents an evaluation of street sweeping and washing by PM10 measurements and determination of silt load from active traffic streets. A modified Regenerative-Air Vacuum Sweeper (RAVS) and a washer were used. It was found that the impact of sweeping alone on ambient PM10 concentrations was short-lived, lasting no more than about 2?3 h. The method of sweeping followed by washing tested ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

  • Enhesa – Enforcement Corner

    As EHS regulatory activity continues to grow, enforcement continues around the world. Below are just a few examples of recent EHS enforcement actions. On 20 June 2011, an oil company branch in the United Kingdom was ordered by Ipswich Crown Court to pay a total of £1.24million in fines and costs over the explosion and fire at one of its gas terminals on 28 February 2008. The explosion blew ...

  • A Neural Model for SPM Concentration Prediction in Coal Mines

    ABSTRACT Coal mines are the major sources of suspended particulate matter. To implement any control techniques or to install any control equipment around the coal mines, ambient concentration of suspended particulate matter should be known. In this paper a model is developed to find the concentration of suspended particulate matter at various locations away from the source. The model is ...


  • Air quality issues drive vehicle alternatives

    Vehicle exhaust systems remain a major source of air pollution in cities, despite the progress being made to reduce emissions from new models. Energy World takes a look at efficiency improvements, and the alternative fuel alternatives to petrol and diesel. In early April, the south of Britain woke to a hazy blanket of smog. A few weeks earlier, Paris had choked and spluttered through its own ...
