Description of key information

All selected NOEC/EC10 values from chronic microbial tests are summarised in the following table. All these values are considered reliable (Klimisch score 1 and 2) and relevant for the effects assessment. In total 9 individual high quality NOEC/EC10 values (for 2 microbial processes) are selected for the PNEC derivation, ranging from 3 mg B/kg for substrate induced nitrification in Zwijnaarde soil (Van Laer et al., 2010) to 419.6 mg B/kg for nitrogen transformation (Förster and Becker, 2009b).
