Abstract
The application of reference materials (RMs) for quality control in analytical chemistry within long-term environmental monitoring and banking programs is described. The profitable use of different levels of RMs, in particular the introduction of problem-designed internal control materials and internal reference materials at the German Environmental Specimen Bank is demonstrated. Moreover, further demands from biosphere-oriented programs for future developments of certified reference materials (CRMs) are discussed.
