  • Design methodology for background air pollution monitoring site selection in an urban area

    We present an air monitoring site selection procedure to determine the minimum number and location of monitoring stations to identify the occurrence of background concentrations greater than a reference value in an urban area. The objective technique reported here is based on the analysis of concentrations estimated using an urban dispersion model for at least one year of hourly information. As ...

    Brownfields are properties that have, or may have, contamination or the stigma of contamination that hinders the reuse of land for new development. The lure to these properties is great – seemingly prime, large tracts of land being sold for relatively inexpensive prices; the vision of unrestricted development; putting residential communities on these lands and reaping a great return. To further ...

  • High resolution maps of nitrogen dioxide for the Province of Styria, Austria

    Knowledge about the spatial distribution of NO 2 concentrations is beneficial for setting up air quality measurement plans, assessing exposure, or in licensing procedures, where background concentration levels are required. Styria (16.400 km², 1.2 million population) is the second largest province in Austria. In order to take topographical effects on the pollutant dispersion into account, wind ...

  • The Application of TO-15 to Naphthalene Measurements in Indoor Air

    Introduction Naphthalene has recently become a compound of concern in many vapor intrusion investigations as a result of its reclassification to a carcinogen by California EPA and its proposed change to a 'likely carcinogen' by the USEPA. Naphthalene is commonly found in petroleum-based fuels and may be present at former manufactured gas plants. To assess the health risk of naphthalene vapor ...

  • Asbestos management goes digital - Mobile solutions for asbestos tracking

    Compliance with new regulations is nearly impossible using only paper-based systems, especially for owners of large numbers of buildings. A critical component of any asbestos management strategy is the effective application of technology – but selection and implementation of systems can mean a large investment of both time and money. The objective of this article is to provide an explanation of ...
