All selected NOEC/EC10 values from long term single-species toxicity tests with higher plants are summarised in the respective table listing effects to terrestrial plants. All these values are considered reliable (Klimisch score 1 and 2) and relevant for the effects assessment. Thereby all data are based on added doses (nominal or measured), as background concentrations are not always available and the added risk approach will be followed because of the significant difference in bioavailability between boron naturally present in soils and added soluble B. In total 192 individual high quality NOEC/EC10 values (for 28 different species) are selected for the PNEC derivation, ranging from 3 mg B/kg for barley root elongation in Zwijnaarde soil (Van Laer et al., 2010) to 84.0 mg B/kg for wheat shoot length, canola shoot yield and western wheatgrass root yield (Aquaterra, 1998). A large number of papers were assessed from the literature, yet only a limited toxicity dataset could be created due to the poor quality of most of the data.
