As mentioned previously in this book, CRMs should match as much as possible the composition of real samples , e.g. inhomogeneous soil samples may be more representative than finely ground powdered material which may create more problems to laboratories than actually offer them useful tools for their analytical quality assurance (i.e. finely ground soil materials are easier to analyse than real soil samples). 

This book attempts to cover chemical and ecotoxicological analysis related to routine contaminated land investigations. It does not cover analysis related to research or specialist one-off project type investigations. The following chapter deals with soil analysis method requirements, how methods should be validated and the need for all methods to meet clearly defined performance requirements. It also covers quality assurance/quality control aspects. Chapter 3 covers the key, and problematic area of sample homogenisation and the initial sample preparation. Chapter 4 covers the analysis of metals and elemental... 

The public health implications required a rapid, yet reliable assessment of these sites. A cost-effective procedure was developed to analyze for 2,3,7,8-TCDD down to 1 part per billion (ppb) in hundreds of soil samples ( ). From late 1982 thru 1985, over 13500 samples were analyzed by 50 different laboratories using procedures based on isotope dilution and high resolution gas chromatography with low resolution mass spectrometry. A comprehensive quality assurance program was implemented to assure the reliability of data generated during this massive monitoring effort ( 3).

In Figure 7.53 a flow-injection interface for fluorometric monitoring of focused microwave-assisted Soxhlet extraction is represented [195]. This assembly allows real-time online monitoring of the PAHs extracted from solid samples in each Soxhlet cycle and provides qualitative and semi-quantitative information from natural and spiked samples. The method has been applied to a certified reference material (CRM 524, BCR, industrial soil/organics) for quality assurance/validation. The proposed technique is as efficient as conventional Soxhlet to extract PAHs from soils but with a drastic reduction of both extraction time and organic solvent disposal.

Professionals working with GC analyze the content of a chemical product, for example in assuring the quality of products in the chemical industry or measuring toxic substances in soil, air or water. GC is very accurate if used properly and can measure picomoles of a substance in a 1 ml liquid sample, or parts-per-billion concentrations in gaseous samples.
