Reliable and metrologically comparable results of quantitative analytical methods are essential to assure that decisions taken on their basis have meaning and context. Problems with combining measurement results, calculating their uncertainties and establishing metrological traceability can prove complicated and ambiguous for measurement scientists. Combining and Reporting Analytical Results discusses in detail the problems faced by scientists, and presents a variety of approaches across biological, chemical and environmental sciences to resolving these types of issues. Topics include: validated methods of analysis; application of internal quality control procedures; participation in proficiency testing schemes; metrological traceability of measurement results and associated uncertainties, as well as some quality system issues and formal accreditation. Written by leading experts, and with worked examples and illustrations throughout, this invaluable reference source is ideal for analysts from various scientific fields.

1 INTRODUCTION

The objective of environmental monitoring is to quantify the condition of ecological systems in spatial and temporal differentiation. The organized and systematic measurement of selected variables provides the establishment of baseline data and the identification of both natural and human-induced changes in the environment. Therefore, spatially and temporally measured values have to correspond to real conditions and not to different measurement methods. In addition, the environmental monitoring enables to guide the formulation and the implementation of environmental management policies designed to protect human health and well-being, which includes ecological well-being. In general, the objectives of environmental monitoring programs can be summarized as follows;

• to verify the compliance with national or international environmental quality standards;

• to provide a basis for the implementation of environmental legislation;

• to assess human population and ecosystem exposure to pollution.


To reach these objectives, both at national or international level, a combination of a high amount of environmental data are necessary, collected in different period and coming from different sources. In the case of data used to provide information on the status of natural values and threatening processes, and to determine the type and magnitude of trends over time in assessing long-term trends, quality assurance, high precision and consistency of data, are of the utmost importance. The same considerations are valid if the monitoring data are used to evaluate the pattern of environmental contamination across a country or Europe. In addition, the assessment of compliance with national or international environmental quality standards, is vitally dependent on reliable environmental data. In this frame, the analytical laboratories have a great role, as the results of analytical measurements may be the basis upon which economic, legal or environmental management decisions are made, and they are essential in international trade, environmental protection, safe transportation, law enforcement, consumer safety and the preservation of human health. It is essential that such measurements are accurate, reliable, cost effective and defensible to ensure that correct decisions are made. This requires data determined with standardized methods, measurement results traceable to national or international standards with a stated measurements...
