Quality of measuring and urban enviromental stations.

Abstract

Society is daily influenced by analytical measurements on which legal, commercial and social decisions are based. The accuracy of a chemical measurement is fundamental, depending on its purpose, but it becomes still more important when analysis concerns the state of the environment and human health. Industrialised countries generally spend about 6% of their gross internal balance on measurements and related operations. Much of these costs are wasted as they duplicate analysis already performed and relate to untraceable analytical data.
