Interlaboratory Studies and Certification of Reference Materials for Environmental Analysis gives an account of the importance of reference materials for the quality control of environmental analysis and describes in detail the procedures followed by BCR to prepare environmental reference materials, including aspects related to sampling, stabilization, homogenisation, homogeneity and stability testing, establishment of reference (or certified) values, and use of reference materials. Examples of environmental CRMs produced by BCR within the last 15 years are given, which represent more than 70 CRMs covering different types of materials (plants, biological materials, waters, sediments, soils and sludges, coals, ash and dust materials) certified for a range of chemical parameters (major and trace elements, chemical species, PAHs, PCBs, pesticides and dioxins).
The final section of the book describes how to organise improvement schemes for the evaluation method and/or laboratory performance. Examples of interlaboratory studies (learning scheme, proficiency testing and intercomparison in support to prenormative research) are also given.
