Description of key information

Additional information

The effects of DIDP, an analog to DIUP, in a long-term toxicity study on the moor frog (Rana arvalis), a vertebrate, was evaluated by Wennberg et al. (1997) in a natural sediment. The authors assessed egg hatchability followed by tadpole survival and growth over a 29-day exposure period. DIDP at a measured concentration of 657 mg/kg sediment (dry weight)did not demonstrate a significant effect on frog egg hatching success following a 14-day exposure and tadpole survival and growth following a 29-day exposure. The 29-day LC50 and NOEC values were >657 and 657 mg/kg sediment (d.w.), respectively.
