Abstract: Beryllium (Be) is known to be one of the most toxic elements but at the same time exerts a stimulating effect on plant growth. Despite this contradiction, little is known about theBemetabolism in living organisms, partially becauseof thelow amountspresent and because the analysis ofBe in plants byICP-MS remains challenging. The challenges arise from the complex organic matrix, the low abundance of Be relative to the other plant essential elements, and the matrix effects resulting thereof in the plasma. To address these challenges, wedeveloped and evaluated a newmethod for Be concentration anal- ysis in plant material. Key is the quantitative separation of Be from the other matrix elements by cation-exchange chromatography. The new method was verified by pro- cessing seven reference materials representing different plantmatrices yielding a long- term reproducibility of 16% (RSD). Applying the method, Be concentrations in tree, shrub, bush, and grass samples grown in non-polluted ecosystems from four temper- ate forests and a tropical rainforest were measured. The Be concentrations in different plant organs range from 0.01 to 63 ng/g that suggest a natural baseline for Be concen- trations of 52 ng/g (95 percentile of non-woody tissue) that may serve as bioindicator for Be pollution in the environment.Comparison of Be concentrations in plants with the soil’s biologically available fraction revealed that Be is discriminated from uptake into shoots and thus can be considered as non-essential.
