  • 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, ...

  • Why monitor dust in the workplace?

    Almost any place of employment can present a potential threat to health and safety from airborne particulates and aerosols. It is important to note, however, that dust hazards are not necessarily visible to the human eye and that the finest particles can represent the greatest threat because of their ability to travel deepest into the lungs. Effective monitoring is therefore key to the ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Reflectance spectroscopy as a tool for settled dust monitoring in office environment

    The aim of this study was to develop a technique based on reflectance spectroscopy that is capable of evaluating small amounts of sediment dust. Laboratory simulations and two field experiments conducted in the same office environment were carried out to generate particulate dust samples based on multivariate data analyses. Spectral measurements were taken using either a laboratory Quantum 1200 ...

  • 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, ...

  • TSI dust monitors and Lufft weather sensors make a great team

    Both aerosols and wind speed and direction influence air quality significantly. This is why TSI Incorporated, a world leader in particle measurements, cooperates with Lufft USA in order to provide complete systems to measure PM2.5 (fine dust), PM10 (particles with a maximum diameter of 10 μm) as well as total PM levels. TSI Incorporated offers a variety of aerosol ...

  • Monitoring surface water chemistry near magnesium chloride dust suppressant treated roads in Colorado

    Received for publication January 31, 2009. Magnesium chloride (MgCl2)-based dust suppression products are commonly used throughout western United States on nonpaved roads for dust suppression and road stabilization by federal, state, and county transportation agencies. The environmental implications of annually applying these products throughout spring and summer months on adjacent stream ...

  • Radiation Monitors and Meters

    Light Description and Applications The light meter is a portable unit designed to measure visible, UV, and near-UV light in the workplace. (The CTC has a UV light meter available through its loan program, ALEP.) The light meter is capable of reading any optical unit of energy or power level if the appropriate detector has been calibrated with the meter. The spectral range of the instrument is ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...

  • Operating Principle of an Oxygen Monitor

    The oxygen concentration in the flue gas of a combustion process such as that of a power plant or a waste incinerator gives a good indication of the efficiency of the combustion process. The parameter is therefore of great interest to optimize fuel economy, but also to control and reduce emissions of air pollutants. An ideal combustion process only results in CO2 and water, but ...

  • How to Monitor Mercury Emissions

    In recent years, mercury levels in the environment and in the food chain have risen substantially mainly due to human activities. As a long-range pollutant it can affect areas located thousands of kilometers away from its original source of emission. It’s no wonder then that the regulatory pressure to monitor mercury emissions grows stronger.  Before diving ...

  • What You Need to Know About Cyclone Dust Collectors

    Cyclone dust collectors are brilliant cleaning devices and once you have decided to use one, you must understand the job it does. A cyclone dust collector is different from other dust collectors, which is the first thing so you don’t get confused. Dust collectors remove dust particles as well as harmful pollutants flowing in the work environment. However, cyclone dust collectors are more ...
