Abstract

Plant analyses are performed routinely for the assessment of their quality e.g. for feed and food but they can also be used as indicator organisms for environmental threat. Clover and grass for animal feed are analysed to determine elements of nutritive importance and of potential toxicity; other plant materials are used to assess the global distribution pattern of a wide range of elements in the ecosystem and to study the element fluxes through the environment from rain, airborne dust or soil and water to plants, animals and humans. To improve the quality of results in plant monitoring, the Community Bureau of Reference has developed a series of certified reference materials (CRMs) for the monitoring of trace elements in aquatic and terrestrial plants, and of major and trace elements in animal feed. This paper gives a brief outline of the CRMs already available and presents the most recent CRM of this series ie. a white clover grown on a soil relatively rich in Se. The results of an intercomparison of trace elements in two lichen samples are also presented.
