Australia has very stringent controls and standards regarding chemical manufacturing. That doesn't mean I advocate cupboards full of potentially hazardous potions used liberally for any and all occasions - just that common sense and established scientific research should be applied.
This website dispels some common myths around chemical use in Australia. (FTR I'm not entirely comfortable with everything this website says but it provides links to the research it uses and if I had the time and inclination I would investigate further.)
Again (and I can't emphasise this enough), I am not trying to be antagonistic, I just believe that statements need to be supported with links to research.
