  • Monitoring Airborne Contaminants in Workplace Atmospheres, Using Sampling Devices and GC or HPLC

    Workers' exposure to hazardous substances must be held within acceptable limits. Therefore, airborne contaminant vapor and particles (including aerosols) in industrial atmospheres must be monitored. In the United States, the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) offer, for many such substances, specific ...

  • 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, ...

  • Exposure to dust, endotoxin and airborne microorganisms in wastewater sludge thermal drying units

    The objective of this study was to assess workers' exposure to bioaerosols in sludge drying units. Simultaneous collection of inhalable dust and airborne biological agents was carried out using rotating cup samplers (CIP 10, Arelco). Sixteen stationary and 30 personal measurements were performed in three drying plants, during summer and winter. Microbial content of air was characterized by high ...

  • 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:  ...

  • Monitoring Air Makes Sense

    Did you know that air filters were originally put in air handling systems to protect the life of the equipment, not human life? And that it is not uncommon for air filters to get changed less frequently to save on maintenance costs? Monitoring input from sensors can tell operators when filters and media need changing. We have required food labels that list all ingredients. Why not electronic ...

  • Plant area monitoring at Krško

    Post-Fukushima upgrades at Krško in Slovenia (www.nek.si) are being implemented in accordance with the requirements of the national regulator and the plant owners. The first phase, including a passive containment vent filtering system and hydrogen recombiners, a new emergency diesel generator, and a protected store of mobile emergency equipment, is already completed. The next phase in ...

  • Modeling streamflow from coupled airborne laser scanning and acoustic Doppler current profiler data

    The rating curve enables the translation of water depth into stream discharge through a reference cross-section. This study investigates coupling national scale airborne laser scanning (ALS) and acoustic Doppler current profiler (ADCP) bathymetric survey data for generating stream rating curves. A digital terrain model was defined from these data and applied in a physically based 1-D hydraulic ...

  • Assessment of levels and “health-effects” of airborne particulate matter in mining, metal refining and metal working industries

    The increased awareness of occupational health, hygiene and safety in recent years has resulted in improvement of working conditions and in reducing workers’ exposure to many toxic substances. However, substantial hazards remain, the number of cases of occupational illness due to hazardous exposure is still high, and new cases will continue to occur if there are no further improvements. During ...

  • Carbotrap Carbon Black: An Excellent Adsorbent for Solvent or Thermal Desorption/GC Analyses of Airborne Organic Compounds

    Carbotrap adsorbent traps and releases a wider range of airborne organic compounds than Tenax GC or Amberlite XAD-2 resin. Compounds adsorbed by Carabotrap adsorbent can be completely recovered through either solvent or thermal desorption. Carbon disulfide, a highly effective desorbing solvent, degrades Tenax GC and Amberlite XAD-2, forcing you to use potentially less effective desorbing ...

  • 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 ...

  • Detection of Airborne Viruses in a Pediatrics Department Measured Using Real-Time qPCR Coupled to an Air-Sampling Filter Method

    Children are vulnerable to viral infections. The study discussed in this article investigates the possibility of aerosol transmission of viruses in children under age 18 in the pediatrics department of a medical center in Taipei, Taiwan. After first using the filtration method to collect viral aerosols, the authors combined it with real-time quantitative polymerase chain reaction (qPCR) to detect ...

  • Wireless monitoring for a safe indoor environment

    This article discusses the benefits of wireless technology for continously monitoring the indoor environment. In striving for the construction of energy efficient and cost-effective buildings, the imperative issue of the buildings Indoor Air Quality (IAQ) is often overlooked. This can often lead to a unhealthy indoor environment and even to conditions such as Sick Building Syndrome (SBS) or other ...

  • Exposure to environmental tobacco smoke at work, at home, and during leisure time: personal exposure measurements by diffusive sampling of airborne 3-Ethenylpyridine

    Environmental tobacco smoke (ETS) is associated with an increased risk of several diseases. In 2002, the ETS exposure level was studied in a Finnish cross-sectional population sample with a sub-sample of currently working nonsmokers. In all, 123 nonsmokers (25-64 years) reporting at least 1 h of daily exposure to ETS participated in personal exposure measurements. Two 3 M organic vapor monitors, ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

  • Why is there no effective real-time Continuous Radiation Monitoring System?

    Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...
