  • Measurement of Trace metals in Ambient air case study

    Trace metals are found at low concentration in the ambient environment and are associated with adverse health effects. The gold standard metal measurement is Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES); however, sample preparation is laborious and expensive. The Xact 625 metals monitor uses non-destructive X-ray fluorescence technology. A built-in sample collection system ...

  • Intraurban variability of Ambient PM Arsenic and other air toxics metals case study

    The Missouri Department of Natural Resources (MoDNR) and Washington University participated in a project to collect and analyze air toxics metals data. It was funded through a Community Air Toxics Grant from the U.S. Environmental Protection Agency (USEPA). The study grew out of the southside St. Louis Community Air Project (CAP) which identified six hazardous air pollutants of concern including ...

  • Indoor air quality can be improved by employing plants as walls

    The practice of planting ivy to climb up the walls of buildings has existed for centuries. Now, the trend towards sustainability and green building practices can lead to the development and use of living walls as a means of filtering and improving a building’s indoor air quality. Green walls are a living, breathing, regenerating type of cladding that can be as simple as a living art installation ...

  • Microbial reduction efficiencies of filtration, electrostatic polarization, and UV components of a Germicidal Air Cleaning System

    Abstract: This study determined the effectiveness of components of a germicidal air-cleaning system involving filtration, electrostatic polarization, and UV light on the reduction of airborne bacteria and molds. The filter alone, filter and electrostatic polarization combined, and the filter, electrostatic polarization, and UV light were found to be effective (P < 0.05) in reducing a given ...

  • Urban Air Quality Management

    ' Poor air quality due to pollution is a serious environmental problem in most urban areas. The greatest burden of pollution is on human health. Urban air quality management requires an integrated approach that (i) identifies the most serious problems and measures that offer cost-effective and feasible solutions across a range of economic sectors and pollution sources including industries, ...

  • 10 easy fixes for indoor air

    Colder temperatures are upon us, and most people keep windows and doors shut to keep the chill out. But in closed-off rooms and homes, indoor air contaminants build up over time. The problem? Poor air quality has been linked to health effects in everyone, especially infants, children, seniors and pets. We listed 10 easy ways to improve IAQ. 1. Open windows ...

  • Filter damage monitoring with Dusty Ex - Case Study

    Application A chemical manufacturer producing photoinitiators. Photoinitiators are chemical compounds, which disintegrate after the absorption of light in a photolytic reaction. They produce reactive compounds, which are able to initiate a chemical reaction (for example a polymerisation). In praxis these initiators are used to harden lacquers and paints under the infl uence of ...

  • Field demonstration of a near-real-time multi-metals ambient fence line monitor case study

    National emissions standards for hazardous air pollutants (HAPs) are required under Section 112 of the Clean Air Act to limit the release of specified HAPs. Permitting, monitoring and enforcement of these emission limits are an integral part of managing air quality to protect human health and the environment. However, this is difficult and highly uncertain in the case of fugitive emissions ...

  • Gas-phase air filtration: Protecting you from what you can’t see

    Air filtration, covered previously, targets solid matter (particulates) such as dirt, dust, leaves, and any visible airborne debris. Gas-phase filtration is for the unseen pollution that is airborne gases that may have an odor–but not always. This is chemistry that came from a liquid or solid to become a gas at ambient temperature. Gases act very differently than particles since they are ...

  • Dust monitoring with AirSafe - Case Study

    Application A waste incineration plant burns waste. A fi nal product of this incineration process is fi lter dust, which is stored in silos before being evacuated. For the ambient air monitoring of the silos, convey lines and connected rooms, the plant manager looked for a maintenance-free way to detect dust leaks and malfunctions. Optical techniques were not ...

  • Compressed breathing air safety - how important is it?

    At first glance the physiological demands of the firefighter, the scuba diver and the hospital patient have little in common. One is trained to deal with fire and rescue, one swims underwater and one is concerned with either regaining or improving their health. Yet all three depend to some extent on a safe source of compressed breathing air, which is where our gas detection systems come in. ...
