In Hamilton 10 years ago, we had lead exceedance in our water. This week, cities across Canada are finding out that there's lead in the drinking water: “Oh, what are we going to do about it?” We already looked at this 10 years ago.
That brings me to you, Dr. Merali. I know that exposure to lead at levels generally considered safe is showing in more recent studies to be problematic, especially with regard to depression and behaviours and so on. You did the brain imaging. I know that some of the other researchers have found a decrease in the frontal lobe.
As regards our topic, are there predictors of behaviour that you could test even in recruits, as well as veterans, to see whether they might be predisposed to mental behaviours?
