The EC50 for growth rate reduction (72h-ERC50) was 0.039 mg/l with a 95% confidence interval ranging from 0.035 to 0.048 mg/l based on TWA concentrations. The 72h-NOEC for growth rate reduction was 0.0031 mg/l.
Based on these data, pymorolac is classified as Acute Aquatic toxicity Category 1 Regulation (EC) 1272/2008 (CLP). Based on these data, pymorlac is classified as acute aquatic toxicity Category 1 according to Regulation (EC) 1272/2008 (CLP), with an M-Factor of 10. These same data can be used to determine the classification for Chronic Toxicity. With a NOEC of 0.0031 mg/L, pymorolac meets the criteria for Chronic Toxicity Cat 1 (non-rapidly degradable substances with NOEC <0.1 mg/L ). M-Factor = 10
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
