Description of key information

A 28-day NOEC value of ≥25 mg/L (as active acid) has been determined for the effects of ATMP-H on adult survival and reproduction of D. magna.

Key value for chemical safety assessment

Additional information

A 28 day NOEC value of ≥ 25 mg/L (as active acid) has been determined for the effects of the test substance on adult survival and reproduction of D. magna. The study represents the lowest reliable value available for this endpoint. A study of unknown reliability determined a NOEC of 3 mg/L. However the pattern of results was erratic and not enough information was provided in the report to determine the cause.

A 96 h NOEC value of 96 mg active acid/L has also been determined for the effects of ATMP-H on the growth of the eastern oyster Crassostrea virginica.
