• calculate
  • Numerical simulations were used to calculate the total dust flux from the sources as 180,000 and 280,000 tons for each storm. (mdpi.com)
  • storms
  • Particulate matter mass concentrations and size fractions of PM 1 , PM 2.5 , PM 4 , PM 10 , and PM 15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. (mdpi.com)
  • Both dust storms occurred in relatively densely inhabited areas of Iceland. (mdpi.com)

  • Within a few short years, the Owens Valley's riverine environment had undergone a profound transformation, unleashing a series of immense dust storms that continued to blow until the turn of the twentieth century. (au.dk)
  • Following these dust storms as they traffic through homes, into human bodies, and throughout the intensely anthropogenic airscape of Central California, this paper enquires into the shifting textures of everyday life in the shadows of the Los Angeles Aqueduct. (au.dk)
  • filter
  • The Opsis SM200 is a combined particulate monitor that can be used for both automatic measurement and filter sampling. (environmental-expert.com)
  • One technique uses a device that collects particulates on a filter strip and periodically shines light through the strip to record the difference in light transmittance. (vernier.com)
  • At the same time filters that are suitable for volatile substances must typically have their filter elements replaced more often than a particulate filter. (wikipedia.org)
  • citation needed] In 1848, the first US patent for an air purifying respirator was granted to Lewis P. Haslett for his 'Haslett's Lung Protector,' which filtered dust from the air using one-way clapper valves and a filter made of moistened wool or a similar porous substance. (wikipedia.org)
  • mass
  • The technique achieves microgram -level mass resolution even in the hostile mine environment and reports dust loading data on a continuous basis. (mst.edu)
  • research
  • First results on size partitioning of Icelandic dust presented here should challenge health authorities to enhance research in relation to dust and shows the need for public dust warning systems. (mdpi.com)
  • Research on wood dust health hazards comes within the field of occupational health science, and study of wood dust control comes within the field of indoor air quality engineering. (wikipedia.org)
  • relation
  • All these organisations recognize wood dust as carcinogenic in relation to the nasal cavities and paranasal sinuses. (wikipedia.org)
  • estimate
  • Images from a camera network were used to estimate the visibility and spatial extent of measured dust events. (mdpi.com)
  • Quality
  • When talking about air quality around animal agriculture, one of the most common neighbor complaints comes from dust (sometimes also called particulate. (extension.org)
  • problems
  • Many local governments have enacted general nuisance ordinances, which typically contain provisions aimed at such problems as illegal burning, dust, and noxious odors. (mrsc.org)
  • often
  • A nephelometer measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam. (wikipedia.org)
