Additional information

Algal growth inhibition has been investigated on three structural analogues of the registered substance, the selected study being on the closest structural analogue to the registered substance. Tests were conducted according to OECD test methods and dissolution/dispersion agents were used to increase concentration of two of the substances in the test medium. Other studies investigated the effects of a water accommodated fraction resulting in significantly lower levels of exposure.
