  • Development of dry deposition velocity model for a typical medium level Indian city Karaikudi

    In this study, day and night dry deposition samples were collected with Eagle II arrangement of dry deposition plates. Karaikudi, one of the medium level city in India has been the chosen as area of study. Sampling locations were classified as zone1, zone2 and zone3. Wind speed was also recorded during sampling. Particle size was determined by using X–ray diffractometer (XRD). Relation between ...

  • Long-term Atmospheric Mercury Wet Deposition at Underhill, Vermont

    Section 112(m) of the 1990 Clean Air Act Amendments, referred to as the Great Waters Program, mandated an assessment of atmospheric deposition of hazardous air pollutants (HAPs) to Lake Champlain. Mercury (Hg) was listed as a priority HAP and has continued to be a high priority for a number of national and international programs. An assessment of the magnitude and seasonal variation of ...

  • Particle Monitoring in Sterilizing Tunnels

    Portable aerosol particle counters are designed to sample ambient air at 1 cubic foot per minute (1 cfm) and no greater than 35 oC. There are however applications which are based on ambient temperatures much greater than this, such as pharmaceutical sterilizing tunnels. Sterilizing tunnels are used to ensure sterility off glassware (vials, syringes, bottles) prior to their entry onto an aseptic ...

  • Manifold Particle Monitoring: Traditional Limitations

    In traditional manifold systems, a powerful pump pulls air simultaneously from as many as 32 different monitoring locations, with each location as far away as 125 feet. This large cumulative length of tubing, plus the volume of air being moved, requires the pump to create a strong vacuum. As a result, the particle counter samples air from the manifold at a vacuum. The counter no longer draws air ...
