After a 21d-exposure period, the total number of living offspring produced per parent animal which did not die accidentally or inadvertently during the test was assessed. In addition, the reproduction was calculated based on the production of living offspring by the surviving parent organism. The reproductive output of the Daphnia exposed to the test item was compared to that of the control in order to determine the Lowest Observed Effect Concentration (LOEC) and the No Observed Effect Concentration (NOEC) according to Williams Multiple Sequential t-Test procedure. Additionally, the survival of the parent Daphnia and the time to production of first brood was determined.
(time-weighted mean) [mg/L]
After A 21 day period, a NOEC of 0.005 mg/l (measured concentration) was obtained on the basis of reproduction.
