One of the things that the health and environment communities, and even industry, have been pushing for in Canada over the last while has been better biomonitoring, or better testing of populations. What we're doing a lot more of is measuring emissions, and what we're doing a lot less of is actually figuring out how much people are being exposed.
Although body testing isn't perfect, it still gives us an indication. The U.S. is miles ahead of us in terms of having comprehensive testing programs that they do regularly and where they're getting a sense of whether chemicals are going up or down. We're big proponents of that as part of a general environmental health surveillance system that will allow us not only to look at where the emissions are happening, but also to get a sense of how contaminated our house dust, the air we're breathing, and our soil are in terms of people being exposed, and what kinds of chemicals people are being exposed to through food, measured by the way they're accumulating in their bodies.
