Effect values for the toxicity test with Aliivibrio fischeri using the porewater or the solid phase as test sample of the sediments from Atleverket wetland system. For the porewater a sample is considered toxic if an IC20 value can be determined at the highest concentration tested. The solid phase value in bold text exceeds Guideline 1 for classifying sediment as toxic according to the Canadian test method EPS 1/RM/42 (i.e. 0.5% w/v).
