The lowest aquatic effect concentration for the test substance is
available from a 72h algae (Skeletonema costatum) study. The NOEC and
ErC50 values from this study based on mean measured test concentrations
are 0.0087 and 0.45 mg/L, respectively. These values were used to
determine the appropriate classification and labelling for the substance
for Aquatic acute Cat 1 (very toxic to aquatic life).
The ErC50 from the 72h algae study coupled with the observed lack of
ready biodegradation for the substance were used to determine the
appropriate classification and labelling for the substance for Aquatic
Chronic Cat 1 (very toxic to aquatic life with long lasting effects).
