Description of key information

The no observable effect concentration (NOEC) for reproduction after 21 days was greater than or equal 138.7 µg/L. 

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
138.7 µg/L

Additional information

"Should read: > 138.7 µg/L"

lmmobilization of parent animals was not affected by the substance. The slight decrease in the number of broods per animal following the exposure to estradiol is not considered a substance-related effect since it is not concentration-related.
