Book Description
An analytical method was optimized to determine the concentration of white phosphorus (WP) in sediments contaminated by smoke munitions. The method uses isooctane as the extractant and a gas chromatograph as the determinative instrument. Both field-contaminated samples and spiked sediments were analyzed and results on the spiked samples indicate that the method has a better than 80% recovery rate for WP. The detection limit for the method is 0.88 microg/kg of soil. The WP recovery is sensitive to the water content of the sediments and to prolonged shaking. Fluidizing the wet sediments by adding water to saturated soil greatly increases WP recovery. Since field samples are contaminated with WP particles of various sizes, subsamples may not accurately represent the concentration of the sample as a whole ...

Book Description
Sediment contamination is a widespread environmental problem that can potentially pose a threat to a variety of aquatic ecosystems. The sediment test methods in this manual will be used by The United States Environmental Protection Agency (USEPA) to make decisions under a range of statutory authorities concerning such issues as: dredged material disposal, registration of pesticides and toxic substances, superfound site assessment, and assessment and cleanup of hazardous waste treatment, storage, and disposal facilities. The use of uniform sediment testing procedures by USEPA programs is expected to increase data accuracy and precision, facilitate test replication, increase the comparative value of test results, and ultimately, increase the efficiency of regulatory processes requiring sediment tests.
