Section 64 covers substances with very different types of issues. Some are of concern to human health in even very small amounts. Some are of concern if released in very large volumes, or if not managed properly, or can be damaging to the environment in a broad sense, but not to the immediate environment. Schedule 1 and the label “toxic” don't differentiate among these characteristics, and that causes confusion. Take, for example, something like ammonia, which has certain useful applications and is of concern only in particular circumstances versus things like dioxins and furans.
So it's a label that covers such a broad range that it doesn't communicate very much, and it can lead people to make assumptions. It makes discussion on how to manage things very difficult, because people tend to assume that everything on the list needs to be managed. For example, for our sector, releases from smelters—they're defined in a particular way—are on schedule 1. How do you compare those to a very specific substance that is used in a food product? You can't, yet the label seems to apply to the whole list, and most people interpret the label in a certain way.
