Description of key information

Two fish acute studies have been reported. One with Danio rerio (Mitschke,

1987), the 96 hour LC50 was found to be between 8.1 -11.5 mg/L. The second study was conducted with Oryzias latipes (Ueda et al, 1991), the 96 hour LC50 was 1.3 mg/L.

Key value for chemical safety assessment

LC50 for freshwater fish:
1.3 mg/L

Additional information

A 96 hour acute toxicity study was performed exposing Danio rerio to a range of concentrations of diphenyl cresyl phosphate (Mitschke, 1987). The 96 hour LC50 was found to be between 8.1 -11.5 mg/L, based on nominal exposure concentrations, the corresponding NOEC was 8.1 mg/L.
