Sum of toxic units (sumTU) over time for primary producers based on the 72 h EC50 from algae test (dark bars) and invertebrates based on the 48 h EC50 from acute Daphnia test (bright bars). SumTU values are given as weekly average and consider the concentration at the time of PPP application (Note: RAC corrected by recovery of dosing solution; values for sulphur are excluded since they are considered as toxic toward sediment organisms only.)
