My first question I want to direct to Dr. Khatter, Hugh, Derek, and then Gordon. It's on the issue of the Stockholm Convention, which was referenced a few times here today. It talks about trace contaminants. They suggest in the annex of the Stockholm Convention that “quantities of a chemical occurring as unintentional trace contaminants in products and articles shall not be considered to be listed...”.
What do you see as the benefits or risks of the approach suggested in the Stockholm Convention?
