I'd rather wait and see how the PCPA changes play out in time. I'm not keen to go down that path, because I think toxic substances are inherently different from pesticides, perhaps. There may be some that are similar and others that are different. They're a broader range of chemical substances that I wouldn't want to force into the same mould as the PCPA employs.
