Description of key information

Chronic toxicity of TCPP to aquatic invertebrates (Daphnia magna) was assessed in a reproduction test, performed according the OECD Guideline for Testing of Chemicals 202, (1984). After 21 days of exposure a NOEC for reproduction of 32 mg/l was determined. 

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
32 mg/L

Additional information

The chronic toxicity of TCPP to aquatic invertebrates (Daphnia magna) was conducted in a semistatic reproduction test according OECD Guideline for Testing of Chemicals 202 (1984). After 21 days of exposure a NOEC-reporduction of 32 mg/l and EC50-reproduction of 40 mg/l were determined. The results relate to nominal concentration, as the exposure concentrations were confirmed by chemical analysis. The analytical monitoring was performed via gaschromatography with external standard calibration. All validity criteria like control mortality, dissolved oxygen, pH, first young, cumulative young per female and number of broods per control group were fulfilled.
