Description of key information

A reliable test result of 48 h EC50 64 mg/l, A. tonsa, nominal concentrations is available for the acid form.

Key value for chemical safety assessment

EC50/LC50 for marine water invertebrates:
64 mg/L

Additional information

A 48h EC50 value of 64 mg active acid/L has been reported for the effects of HEBMP-H acid on the mobility of the marine copepod Acartia tonsa based on nominal concentrations. This result is interpreted as 64 mg/l as active acid. Whilst the proportion of cyclic and linear constituents was not measured for the tested sample, it is conservatively interpreted that the cyclic constituent could have been present at ca. 50% w/w.
