 So ethylene oxide is a carcinogen. It's a mutagen, which means it affects our DNA. So the molecule will impact our DNA and increase the likelihood that we get cancer. And I just want to point out that it's that same method of action is why it's a really good chemical sterilizer. So it's used for sterilizing medical equipment and to kill all the bacteria and viruses that may be on that. So how exactly is this chemical getting out into the surrounding air?
