  • Evaluation of Spatial and Temporal Variability in VOC Concentrations at Vapor Intrusion Investigation Sites

    ABSTRACT As vapor intrusion has become an increasing concern at corrective action sites, the USEPA and a number of state regulatory agencies have recently issued guidance documents covering the collection of subsurface gas, and above-ground air samples during vapor intrusion investigations. Most of these guidance documents do not provide specific recommendations concerning the number of each ...


  • Health And The Environment

    Is there cause for concern? According to the World Health Organization, air pollution is responsible for an estimated 5% of global disease. In addition to acute respiratory infections, air quality is related to the incidence and severity of asthma, heart and lung diseases, allergies, and several types of cancers. Allergies and Asthma Millions in the US suffer from allergic problems ...

  • The MoldScore Report

    When evaluating indoor levels of most pollutants, one can collect air samples, compare the sampling results to established exposure standards, and make relatively unambiguous decisions regarding the need for remediation. Bioaerosols as a group are not amenable to this general methodology, due to the difficulties in the development of such exposure standards for reasons that have been discussed ...

  • Seal Fireplace Dampers With Weatherstripping to Conserve Energy

    Introduction When fireplaces are not being used, they should be sealed with weatherstrip to air seal the damper and prevent wasted energy. The common perception should be that just like doors and windows, fireplaces require weatherstripping to prevent energy loss. Leaking Fireplace Dampers Waste Energy Fireplaces are the largest intentional opening in the ...


  • Screening of volatile organic compounds as a source for indoor pollution

    For a considerable period of time the presence of an increasing number of chemicals has been observed in almost all aspects of human life. This process also affects the living and working environment of man. Human development, including physical and mental health and well-being, depends on to a great degree on the surrounding environment. Considering that an average person spends a significant ...

  • Proactive Indoor Air Quality Surveys Save Budgets

    As facility budgets tighten, managers are realizing the many benefits that money spent for proactive indoor air quality is a smart investment. Here is a simple comparison to exemplify the point. Indoor air quality investigations conducted in response to employee complaint or illness clusters cost $3.00 to $10.00 per square foot of space investigated compared to 2 to 10 cents per square foot for a ...

  • 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 ...

  • Pollution survey of carbonyl compounds in train air

    The train is an important vehicle in China, but its air quality has important impacts on passengers’ health. In this work, pollution from carbonyl compounds was measured in the air of six trains. The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers. The ...

  • Measurement of indoor-outdoor carbonyls at four residential homes in Mexico City metropolitan area

    Formaldehyde, acetaldehyde, acetone, propionaldehyde and butyraldehyde were measured in indoor and outdoor air at three houses and one apartment in the Mexico city metropolitan area (MCMA). Formaldehyde presented the highest concentration in indoor and outdoor air, followed by acetone and acetaldehyde. Indoor carbonyl concentrations were higher than outdoor concentrations at all sampling sites. ...

  • The Economic Value of Air-Pollution-Related Health Risks in China: A Contingent Valuation Study

    The economic value of preventing adverse health effects related to air pollution is estimated using contingent valuation in three diverse locations in China. Values are estimated for three health endpoints: cold, chronic bronchitis, and fatality. Alternative statistical models are tested to study their impact on estimated willingness to pay (WTP) and on the relationship between WTP and respondent ...

  • Indoor Air as a Source of VOC Contamination in Shallow Soils Below Buildings

    US EPA and many state regulatory agency guidance documents recommend below foundation vapor sampling as a key element of site investigations to determine if vapor migration from underlying soil into buildings is a completed exposure pathway (USEPA, 2002; WIDHFS, 2003; San Diego County, 2004; PADEP, 2004). If volatile organic compounds (VOCs) are detected below the building foundation, then VOC ...


  • Feasibility Study of an Express Assessment Protocol for the Indoor Air Quality of Air-conditioned Offices

    It is costly to sample all major toxic pollutants in community air. Sampling should be conducted based on an assessment strategy and monitoring planning. Assessment methods that rely on monitoring some representative pollutants have been proposed variously at different times. In Hong Kong, the Environmental Protection Department (HKEPD) launched an Indoor Air Quality (IAQ) certification scheme to ...
