Part of the environmental risk assessment that's done by PMRA when they determine whether or not to register a chemical turns around some of that issue. Essentially the risk assessments that have been done by PMRA with respect to Alphamax and Salmosan have concluded that if they're used according to the label, they don't pose an environmental risk in the context of their application, in this case in New Brunswick, and possibly in Newfoundland.
