BCS is submitting new information to PMRA related to Iodosulfuron-methyl-sodium (IMS). This information is not necessarily a new adverse effect of the subject chemical, but is rather new information submitted for the Agencys own review and evaluation because the data meet the Agencys administrative reporting criteria. The relevance of these formulation studies to the aquatic risk assessment has a high degree of uncertainty, as IMS has no labeled aquatic use patterns. It is important to note that formulation-based studies do not accurately represent aquatic exposure and toxicity compared to aquatic estimated environmental concentrations that include runoff. Formulations do not runoff as intact components, and comparison of percent active ingredient endpoints derived from the formulation studies may overestimate risk in these cases. The overly conservative approach of comparing endpoints based on percent active ingredient derived from formulations to estimated environmental concentrations calculated on runoff can however offer some insights when considering potential relative risk.
