Default Is intake of excess atm o2 hazardous?

Q.We know that if excess supplemental o2 is given it can result in Oxygen derived free radical damage (like in bronchopulmonary dysplasia etc), but I would like to know, if we intake excess atmospheric oxygen (like doing 2-3 times of longer and aggressive breathing exercises Eg. pranayama) will that too forms o2 derived free radicals resulting in tissue damage?Pls share your thoughts and knowledge on this.
