  • Algal Growth Inhibition: Effect of the Choice of Growth Rate or Biomass as Endpoint on the Classification and Labeling of New Substances Notified in the EU


From the complete base set notifications of new substances currently available, we have investigated what effect the choice of using growth rate or biomass in the algal growth inhibition test has on the relative sensitivity of the three aquatic tests. Both parameters derived from the algal test were more sensitive than either fish or Dapnia tests. Changes in the classification of substances after the removal of either algae. Dapnia or fish data from the base set, when applying current legal practice occur in 22.9%, 6.6% and 4.8% of the notifications respectively.
