Certainly. As we mentioned, the risk management strategy pulls together the risks and sources of a problem and how we should deal with them.
In the area of mercury, the original sources dealt with were large industrial emitters. Since that time, having many of those sources closed off, we are now looking at other sources, and many of those are in products. We have a pollution prevention plan dealing with mercury in lamps. We have measures coming into place--sorry, that's on switches. We have measures with provinces on lamps, and we're doing work on dental amalgam, which is another source that can get directly into the water. It's a very easy solution to deal with.
The risk management strategy sets out what you're trying to achieve and what are the major sources. We're using a mix of regulations, codes of practice, instruments with the provinces, pollution prevention plans--a number of different tools to deal with those.
The monitoring and release information informs us of whether there are ongoing sources that we need to deal with. In this case, it's the research is pointed to sources outside Canada, largely from Asia and other countries like the United States as well.
That is what has taken us into dealing with the United Nations Environment Programme to work on a legally binding instrument that would deal with sources from all countries. It would also help to deal with the fact that products may be manufactured offshore, not in Canada, and imported into Canada. It's very difficult to deal with it once it comes into Canada. It's sometimes difficult to know what the content is.
So it's very important to deal with countries, particularly in Asia, with its big manufacturers, to send the signal that mercury has to be eliminated except for essential products and that in those essential products it needs to be controlled to a certain limit, with labels as to what that limit is.
