Biodiversity and Environmental Philosophy: An Introduction

Illustration of the terms “precision” (reproducibility) and “accuracy” (the “true” value) in analytical chemistry (from Markert, 1996): a. Poor precision and poor accuracy, b. good precision and poor accuracy, c. poor precision and good accuracy, d. good precision and good accuracy, x– ϭ arithmetic mean, vr ϭ coefficient of variation. A. M. G. Zechmeister a matrix similar to the original samples to be measured in the laboratory); and (b) use of independent analytical procedures. With bioindicators we can, of course, carry out repeated sampling to get an idea of how “stable” the bioindicator under investigation is in respect of site and time variations.

2002 (this book)). 6. Strategies and concepts The following reflects only a very small part of the overall existing and proposed strategies and concepts for bioindication. A great many more details on specific programmes are given, for example, by the Environmental Protection Agency (EPA, US), the OECD and the EEA. Further international and national organisations (the International Standards Organisation (ISO), CH), the European Union (EU, Belgium), especially in its section on “Measurement and Testing” (the former Bureau Community of Reference (BCR, Belgium)), Deutsches Institut für Normung (DIN, FRG) and others have elaborated various programmes for environmental control, observation and protection which are available on request via literature search or (more effective) via the internet.

Modern statistical techniques have recently made it possible to indicate the relative contribution of one stress factor to the integral effect of a mixture of stresses. According to Costanza (1992), ecosystem health is a bottom-line normative concept. It represents a desired endpoint of environmental management, but the concept has been difficult to use because of the complex, hierarchical nature of ecological and economic systems. When developing and using (new) indicators, the following points have to be taken into consideration: 1.
