This book was released on 1992 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 ...

Available in PDF, EPUB and Kindle. Book excerpt: White phosphorus from exploded munitions is a difficult contaminant to characterize in the environment. Spatial heterogeneity of concentration estimates is extreme, varying over many orders of magnitude for closely spaced discrete samples. To provide cost-effective data upon which decisions may be made, two composite sampling methods were designed to aid in characterizing the site and monitoring the remedial process for an area contaminated by white phosphorus. For each method, closely spaced discrete samples were collected on a grid pattern and pooled to form composites. The composites were then divided by size fractions. Mean white phosphorus concentrations were estimated for the fine-grain-size fraction that was obtained by suspension with water. The presence of highly toxic solid white phosphorus particles, the form that may be ingested by feeding waterfowl, was determined in the coarse-grain-size fraction that was obtained by sieving.

Mayer and published by Burlington, Ont. : National Water Research Institute, Inland Waters Directorate, Canada Centre for Inland Waters. This book was released on 1981 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An analytical procedure for the determination of various forms of phosphorus in sediments is described. The method has been widely used on a variety of samples such as lacustrine and fluvial sediments, bluff material and some pure phosphorus minerals. It is suitable for the analysis of a large number of samples, because it is possible to carry out extraction in batches and the determinations on the extracts can easily be automated"--Abstract, p. v.
