  • Vapor intrusion and indoor air quality due diligence during property transactions

    Vapor intrusion (i.e. the migration of volatile chemicals from contaminated soil and/or ground water through the subsurface into overlying building structures) as a contributing indoor air has become a growing concern for property owners and prospective purchasers in recent years as it can cause significant indoor air quality problems. This is largely due to the increased focus on this issue by ...

  • Indoor Cats Improve Quality of Exhaust Emissions

    For over two decades, the automotive industry has struggled to keep up with emission standards by installing emission control systems that are increasingly more sophisticated and expensive.  In the meantime, emission control for materials handling equipment has not been a major concern. Without having to meet stringent ...

  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of ...

  • Intellisenc Building Air Quality Controllers control CO2, CO, VOC, O3, Humidity and temerpature.

    The quality of the air we breathe indoor (Indoor Air Quality, IAQ) is typically defined by the air chemical or gas composition and particulates. The sensors available today for sensing the gas composition of IAQ have many features and options. There is a wide application base for IAQ sensing with the most common being the regulation of HVAC ventilation systems for lower energy cost. Using an IAQ ...


  • Air uality in IVF Labs

    Since the birth of the first baby from in-vitro fertilisation (IVF) in 1978, Assisted Reproductive Technology (ART) has grown in importance as techniques and success rates have continued to improve. Put simply, IVF involves mixing sperm and egg in a lab to create an embryo which is then replaced in a woman's womb to develop normally with success being measured in terms ...

  • Air Pollution Is Making Office Workers Less Productive

    Businesses invest a great deal of time and money in interventions that claim to increase workers’ productivity through on-the-job training, new protocols, advice from consultants, and so on. Recent research suggests that there’s a surprising input into productivity that no one ever thinks about: clean air. We all know that air pollution is bad for our health, and researchers ...

  • From air conditioning to urban planning, defaults and standards create dysfunction by design

    How can we stop outdated assumptions from forcing us to waste? Personal heaters are a summer survival tool for many office workers chilled to the bone by hyperactive ventilation systems — an act of self-defense against an epidemic of overcooling that is wasting energy and confounding comfort in not only offices but also large shops, schools and other buildings. An audit ...

  • CO2 vs. VOC Sensors for IAQ - What`s the Difference

    People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...

  • What is a Breathing or Respiratory Zone?

    In the past, vehicle exhaust gas detectors have been installed on or near the ceiling. In contrary, Critical Environment Technologies Canada Inc. (CETCI) has always recommended that they be installed in the breathing zone. Recently, Quebec’s regulation has reinforced CETCI’s recommendations. It states that “dusts, gases, fumes, vapours and mists found in the workplace ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Prevention measures against radiation exposure to radon in well waters: analysis of the present situation in Finland

    Naturally occurring radioactive elements are found in all groundwaters, especially in bedrock waters. Exposure to these radioactive elements increases the risk of cancer. The most significant of these elements is radon which, as a gas, is mobile and dissolves in groundwater. In Finland, water supply plants are obliged to carry out statutory monitoring of the water quality, including radon. ...
