I can provide you with a preliminary answer. If you want more detail, we'd be happy to follow up. We can give you a written submission, if you want, describing the precise parameters of the study.
The brief answer is that under the chemicals management plan, Environment Canada jointly with Health Canada has initiated a scientific review to assess the effects on the environment of microbeads in consumer products. We will also be discussing the issue of microbeads with the Canadian Council of Ministers of the Environment this summer to initiate broader joint work on microbeads. We've also done some literature review so that we understand the various sources of microbeads, which include land-based sources and marine sources. Then, of course, we've had to look at the various jurisdictional authorities that could be used, if needed, to control microbeads in the future.
Again, in terms of more precise parameters we'd have to get back to you, and we'd be happy to do that.
