no, they are considered eatable by the FDA. not that i would recommend eating them.
Yes, although I wouldn't feed it to them on a plate! Paintballs (including the paint) are made entirely from food-grade products and as such are non toxic.
The very first paintballs were meant to mark trees for logging companies, so no. They are both non-toxic and biodegradable.
Paintballs will not harm you if consumed and digested, as they are made from non-toxic materials.
They are non-toxic, but taste awful on purpose. so yes.
Nothing toxic is found in any legally sold paintballs. So long as you get your paintballs from some reputable souce you're safe. In fact there's not really any paint in the balls. It's actually Propylene Glycol, Sorbitol, color dye and sometimes a little wax.
Yes, Bromine is toxic
Phenol is toxic and corrosive.
The question is toxic to what. Not all chemicals which are toxic to humans are toxic to bacteria, and some chemicals which are toxic to bacteria are harmless to humans (which is why we can have antibiotics). There are chemicals (like Hydrogen Sulfide) which are very toxic to mammals that SOME bacteria eat as food. But there are other chemicals like chlorine which are toxic to both humans and bacteria. So the question does not have a simple answer.
yes
yes
No
The Australian plant Kangaroo paw is not toxic to humans or animals.
