  • 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 ...


  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Evaluations of Polar and Highly Polar Ionic Liquid Capillary GC Columns with Environmental Samples

    Ionic liquids are a class of non-molecular ionic solvents with low melting points.  These liquids are unique combinations of cations and anions and can provide a variety of different selectivities when used as stationary phases in capillary gas chromatography.  A number of ionic liquid phases have been evaluated and characterized for selectivity and determined to be polar or highly ...

  • 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 ...

  • The Characterization of Tentatively Identified Compounds (TICs) in Water Samples Collected from Public Water Systems in New Jersey

    Abstract This is a summary report of a detailed investigation in which the analysis of synthetic organic chemicals by Gas Chromatography (GC) and Liquid Chromatography (LC) was conducted on raw and finished water samples collected from public water supplies using ground water as a source of drinking water. All water systems sampled are known to be contaminated by volatile organic chemicals ...


  • Can Composting BMPS Reduce Air Emissions?

    Imagine a scenario where all yard trimmings collected for recycling have to be received, processed and composted under the cover of a building. It would be tough for most yard trimmings composting facilities to survive the expense. Yet this situation could have occurred in Southern California. At one point, the South Coast ...

  • Cartography for air quality monitoring: the geostatistical approach

    Being able to provide quick and accurate pollutant maps from readings at isolated measurement stations is becoming more important today in light of the European norms on air quality and the public’s demand to be informed. Commonly used algorithms for cartography are quick but their accuracy remains to be determined.Firstly, the choice of method is arbitrary and based on user’s subjective ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • Pesticides in Mississippi air and rain: A comparison between 1995 and 2007

    A variety of current‐use pesticides were determined in weekly‐composite air and rain samples collected during the 1995 and 2007 growing seasons in the Mississippi Delta agricultural region. Similar sampling and analytical methods allowed for direct comparison of results. Decreased overall pesticide use in 2007 relative to 1995 generally resulted in decreased detection frequencies in air and ...

  • Formaldehyde and Aromatic Volatile Hydrocarbons in the Indoor Air of Egyptian Office Buildings

    Indoor and outdoor measurements of formaldehyde and the aromatic hydrocarbons: benzene, toluene, ethylbenzene, m,p-xylene and o-xylene (BTEX) were conducted at six offices in a suburban area in Giza, Egypt, during the winter 2003-04 season. The mean indoor level of formaldehyde was 59.79ppb in offices where there was no smoking and 85.01ppb in offices where people smoked. The highest mean level ...

  • Bioremediation of fuel oil spill at a coastal naval air station in the united kingdom

    Introduction Approximately 1000 gallons of fuel oil had seeped from broken storage tank lines into the soil matrix beneath a boiler house. Oil was subsequently forced from beneath the boiler building by periodic heavy rainfall. The fuel oil migrated down a slope into a farmer"s field causing extensive damage to the vegetation and grazing area inhabited by sheep. ...
