Analytical techniques biota analysis

In the early years of analysis data on the bioconcentration of LAS in biota were obtained using radiolabeled compounds and LSC, not distinguishing between parent compounds and metabolites [1,27,30]. These methods were non-specific and the data produced were unreliable due to overestimation. Therefore, it was important to develop accurate and specific analytical techniques in order to isolate and quantify these separately. 

A narrow view of this mission would include only the use of analytical pyrolysis techniques (e.g., pyrolysis-mass spectrometry (Py-MS) and pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS)) to identify and measure contaminants in samples of outdoor air, soils, sediments, water, and biota. In order to include interesting and useful applications of analytical pyrolysis techniques that otherwise might not be mentioned in the other chapters of this handbook, a broader view of environmental applications will be used to include such topics as the use of analytical pyrolysis to gain an understanding of natural enviromnental processes, such as the conversion of plant materials into soil, coal, and petroleum hydrocarbons. This subject was included in a recent review paper describing the use of analytical pyrolysis for environmental research. Several other review papers contain references pertinent to environmental analysis. ...
