There are 18 reliable NOEC or EC10 values selected for 5 different functional parameters for microbial processes. The functional parameters comprise C- and N-mineralization. The selected NOEC and EC10 values on functional parameters vary from 96 to 4144 mg Pb kg-1 (both values observed for respiration). Additionally, 20 NOEC or EC10 values are selected for 8 different enzyme assays, ranging from 132 mg Pb kg-1 for dehydrogenase to 16576 mg Pb kg-1 for phosphatase. The ecological relevance of reduced enzymatic activities is unclear and, therefore these data re not used for PNEC calculation, but only presented as supporting evidence.
