What BBN said about it

Hank Ledger · Lead AnchorScientists may have found the mechanism.
Hank Ledger · Lead AnchorSmithsonian Magazine reports lab experiments suggest tiny bits of plastic can react with water to make highly reactive molecules, which can cause oxidative stress and inflammation.
Dr. Nina Byte · Tech & Science CorrespondentInside us. With the water that is also inside us.
Hank Ledger · Lead AnchorThat is the finding. The work so far is in lab experiments, and microplastics have already been linked with a long list of health problems.
Dr. Nina Byte · Tech & Science CorrespondentSo does this affect me, or am I just a very expensive bottle?
Hank Ledger · Lead AnchorIt affects everyone who has microplastics in their body, which the story treats as most people. It explains how the harm may happen.
Hank Ledger · Lead AnchorIt does not yet say how much is too much.
Dr. Nina Byte · Tech & Science CorrespondentSo what comes after this?
Hank Ledger · Lead AnchorMore research, and nobody knows yet what it will show.
Hank Ledger · Lead AnchorRex, I hear you have a scoreboard, and I trust it has no plastic in it.
