Description of key information
For the assessment of secondary poisoning, the results always have to be expressed as the concentration in food in order to be able to compare it to the PEC.
TheNOELs can be converted to NOECs with the following two formulae:
NOECrat=NOELrat.CONVrat
Conversion factors from NOEL to NOEC for mammalian species Rattus norvegicus (> 6 weeks) is 20 (bw/dfi)
bw = body weight (g); dfi: daily food intake (g/day)
NOECrat=200 x 20=4000 mg/kg/diet
Key value for chemical safety assessment
- Short-term EC50 or LC50 for mammals:
- 20 750 mg/kg food
- Long-term EC10, LC10 or NOEC for mammals:
- 4 000 mg/kg food
