Hmmm!
Here's the rub. Since WW2 the scientists have invented over 25,000 "new" substances. i.e. new chemicals that aren't found in nature.
All the manufacture has to do is to prepare a Material Safety Data Sheet that shows the toxicity of the substance and how such toxicity can be controlled.
It would be impossible to check how "new" substance "A" will react when mixed with "new" substance "B: and "new" substance "Z" so we only have general guidelines. This system is also used on lab rats for any "new" substance that is deemed suitable for human consumption.

Yippee doo! or is it
"Yippee doo?":thumb:The chemicals that are being generated are also breathed in by you, your children and any visitors to your home. If the substance being injected into the atmosphere of the home is capable of changing the actions of a semi-wild animal, then who is to say that it won't affect the people?
Personally, I have banned from my home
all gadgets that emit scents or other fumes into the air.
I saw a wonderful item on the TV one morning. They were discussing the recent massive increase in asthma and eczema in the youth of today when a visiting Doctor explained to the presenter
"To build up their immunity, kids should be allowed to get dirty, play in dirt and even eat dirt."
The presenter nodded sagely and the programme then cut to an advert that showed a housewife spraying a telephone, wiping down door handles and cleaning her floors with a product that "Kills 99% of germs, dead."
