  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...


  • The Spectrex air sampler ideal for industrial hygiene.

    Comments by an industrial hygiene supervisor in Texas "The Spectrex PAS-500 is a great tool for collecting both personal and area air samples. I have yet to have a worker complain about having to wear the pump. The workers appreciate the drastic reduction of weight and size when compared to the traditional low volume pumps. The best advantage of the PAS-500 is the clip that holds the pump ...

  • 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 ...

  • The radiological impact on some workers due to the natural radionuclides from some industries

    A total of 37 different soil samples and 22 air samples were collected from natural industrial sources. The air samples were collected at a height of 1 m above the ground on 10.4 cm diameter filter paper (with a desired collection efficiency) using a high-volume air sampler. The activity concentration levels of naturally occurring radionuclides such as the U-238 series and Th-232 series were ...

  • Concentrations of Atmospheric Sulfur Compounds in an Extremely Snowy Region, the Hokuriku District, Japan

    It is well documented that a more elevated wet sulfate deposition and a more decreased pH are observed in winter than in summer in the part of the Hokuriku District that faces the Japan Sea. This is believed to be due to the extremely high volume of snowfall that contains a high concentration of sulfate. Because the typical pattern of air pressure in winter, i.e., high in the west and low in the ...


  • TVOC measurement for LEED/green building evaluation

    Total Volatile Organic Compounds (TVOC) may be evaluated when building designers/managers are pursuing the Leadership in Energy and Environmental Design Green Building Rating System for New Construction (LEED-NC) EQ Credit 3.2. The latest LEED-NC guidance document specifies that the maximum allowed concentration of TVOC measured in a building (post construction, pre-occupancy) is 500 µg/m3; the ...


  • Using the exhaled breath condensate as a tool for non-invasive evaluation of pollutant exposure

    The aim of the present study was to investigate whether Exhaled Breath Condensate (EBC) can be employed for a better risk assessment among human exposure to heavy metals. The objective was to develop a human bioindicator to be applicable for professional exposure that, compared with other common indicators, presents important advantages: it is non-invasive and it is easily and quickly collected. ...
