Are all chemicals harmful to the body?
All-or-nothing is not the case because any chemical can cause poisoning if a sufficient dose of it is taken into the body. To put it another way, all chemicals have the potential to be poisonous. It is the amount or dose taken into the body that determines whether or not they will cause poisonous effects.
Can you breathe 100% oxygen?
Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can’t see properly, and your lungs, so you can’t breathe normally. So breathing pure oxygen is quite dangerous.
