A high throughput procedure for polycyclic aromatic hydrocarbons (PAHs) assayed for biodegradation in contaminated soils
(2001) In International Journal of Environmental Analytical Chemistry 79(1). p.1-14- Abstract
- This study describes the development of a high throughput procedure for the extraction, purification, and quantification of all 16 polycyclic aromatic hydrocarbons (PAHs) on EPA's priority list, subject to biodegradation assays in a creosote-contaminated soil. We used various combinations of solvents, temperatures, ultrasonication, tumbling, saponification, vacuum centrifugation, adsorption chromatography, gas chromatography, and mass spectrometry to demonstrate that a) individual PAHs were quantified in the soil matrix with coefficient of variations varying between 5 and 28%, b) recovery from a spiked soil was 80% and more for most compounds but dependent on characteristics of the internal standard, c) up to 20 PAH analyses of soil...
