  • Case Study: Highland Elementary School

    Prior to constructing new classroom buildings on newly acquired property adjacent to Highland Elementary School, the California Department of Toxic Substance Control (DTSC) requires that soil testing be conducted as part of a 'Preliminary Endangerment Assessment' (PEA). Ellis is administering testing of soils near existing buildings (lead), and beneath the location of a former hydraulic elevator ...

  • The Key To Controlling Airborne Contamination In Food Processing

    In the food and beverage industry, contamination is always a high priority concern. Small mistakes in handling, preparation, and even in the cleaning of the environment where food comes into contact with surfaces can cause disastrous results that can potentially affect hundreds of thousands of people. Often overlooked is the threat from another source of food contact: air. ...

  • 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 ...

  • Construction sites pollution monitoring - Case study

    Constructing buildings, roads and other infra structure can have a substantial, temporary impact on local air quality. Airborne contaminants generated are spreading around in the surrounding neighborhood during activities (excavation, raw material extraction, demolition, transportation, painting, covering, concrete…), mostly carried by wind. The main construction contaminants include PM10 ...

  • The Effectiveness of HEPA Filters on DNA-Poster

    Abstract Objectives: Most laboratory techniques utilize biosafety cabinets (BSCs) in order to provide contamination control of the experiments. BSCs depend on airflow and HEPA filters to remove aerosols and particulates from the environment. Aerosols may be created constantly by common lab practices, such as centrifugation, pipetting, and opening tubes. The main principals of HEPA filtration ...

  • Why doesn’t Testwell have detachable probes?

    While detachable probe may at first appear a convenient way to add multiple functions to a unit, they will inevitably cause leaks. This is because any detachable probe requires o-rings or a compression fitting, both of which our competitors use for their  field detachable probes. However, compression fittings are highly susceptible to even minute levels of contamination, i.e. airborne dust ...

  • 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 ...

  • Reduction of odor and odorant emissions from slurry stores by means of straw covers

    Swine (Sus scrofa) slurry stored in open storages is a source of airborne contaminants. A customary practice for ammonia and odor control consists of covering the surface of the slurry with floating materials, such as straw. Although straw covers have been proven to generally reduce gaseous emissions, more knowledge is needed regarding how age, moisture content, and microbiological development of ...

  • Nanoparticle Monitoring in Ultra-Clean Manufacturing Environments

    Abstract With its 10 nm sensitivity, the NPC10 NanoParticle Counter bridges the gap between conventional aerosol optical particle counting at 0.1 μm (100 nm) and sub-nm scale airborne molecular contamination. Experimental and field data demonstrate that ISO Class 1 and 2 environments, which have very low concentrations of particles greater than 100 nm, can possess much higher ...

  • Comparison of human exposure pathways in an urban brownfield: Reduced risk from paving roads

    Risk assessments often do not quantify the risk associated with soil inhalation. This pathway generally makes a negligible contribution to the cumulative risk, because soil ingestion is typically the dominant exposure pathway. Conditions in northern or rural centers in Canada characterized by large areas of exposed soil, including unpaved roads, favor the resuspension of soil particles, making ...
