On the representative sampling of plants for multielement analysis

In the multielement analysis of plants sampling appears to be a substantial source of error (up to 1000%). The reason for this is the difficulty for standardization of the procedure. Fluctuations of concentration in the elemental composition of plants determined by biological variety, seasonal and climatic changes, age and height of sampling, soil conditions, etc. call for preliminary investigations. The present contribution describes and discusses the factors which influence the sampling parameters in multielement analysis of plants. Recommendations for representative plant sampling are made.
