How do we prepare for environmental measurements after Europe 1993?
Scientific measurements are used more and more as the basis for important decisions and regulations (legal, medical, environmental). Environmental measurements are becoming a particular case in point with the growing environmental awareness of both public and governments. These measurements also have to be comparable across borders. In order to achieve both credibility and comparability, the fulfilment of the following requirements seems to be needed: (i) express all results of (environmental) measurements in the SI unit for amount of substance, the mole; (ii) ensure their traceability to the mole, the SI unit for the amount of substance; (iii) assess their real performance through regular participation in external quality assessment programmes using undisclosed, real-life samples. Examples of highly unsatisfactory measurement performances are discussed as well as ways in which the situation may be improved. The need for an ethical approach by (environmental) scientists is briefly highlighted.
