I defer to the scientists and the toxicologists on this, but my understanding, and Marian Stanley can explain further, is that phthalates are not retained in the body. They pass through the body. So if a patient, an infant, a child, an adult, were treated with a device containing DEHP, that substance might go into their body, yes, but it would not be retained in the body. It would be expelled within a certain time period.
I ask Marian to comment on that.
