So, here is my problem with this. Yes, things can be toxic, and sometimes it's the product, and sometimes its the process. But regardless, you can't apply a black and white policy because sometimes the only replacement blows (if there is one at all), and it's process is worse.
There was a VERY ugly rumor running around that the foam protection shedding issue on the the Shuttle was caused by a mandate from the EPA to switch chemistries. If it is indeed true, then you draw a direct line correlation to bad things happening. Sometimes a stinky process is the ONLY way to make something that works they way it should, whether it's foam, paint, medication or otherwise, and sometimes the alternative (if there is one), collectively, is much worse or makes the product unusable for its intended purpose.
Yes, you should understand the process, and yes, stinky stuff should be identified and corralled to the extent possible, but to make omelets, you break eggs, and you burn some trees to move up the tech tree.
