Acute effects (48 h) on Daphnia mobility for the negative control (white), the eluates of three concentrations (1, 10 and 100 mg/L) of each of the three test materials (blue colors) and the positive control (potassium dichromate; orange color) as individual values and means of n = 4 (black dash). Effects were calculated in comparison to the mean value of D. magna mobility in the negative control and negative effect values show daphnid immobilization
