| Abstract |
A study was conducted near ethylene dichloride (EDC) production and user facilities to determine ambient EDC levels. The results will be used in health risk assessment studies now in progress. Three geographical study areas were selected, and a 10-day monitoring program was conducted at each. Integrated sampling was conducted over a 24-hour period at 12 locations within each study area. Meteorological measurements, consisting of wind speed, wind direction, temperature, relative humidity, and rainfall were also made. The EDC in the ambient air was collected on charcoal sorption tubes, eluted with an organic solvent, and quantitated by gas chromatographic separation and mass spectrographic detection techniques. Ambient levels of EDC at some locations were found to be in excess of 500 micrograms/cubic meter (125 ppb). These high levels occurred during atmospheric conditions of calm or low wind speeds. The field monitoring activities, laboratory analyses, quality assurance program, and EDC levels obtained are presented in this report. |
