Huh? That seems normal for any organization that accepts donations. Someone has to coordinate how they track and interface with donors (e.g. mailers, webpage, etc) and how they process the donated funds (cheque, bank transfer, etc). In fact that usually takes a modest team of people to plan and deliver, and one of them has to be in charge, hence the Director.
Note, “gift” is commonly a synonym for donation here.
When we’re talking about molecules, millions is usually an extreme understatement. PPB (parts per billion) is a common measure for contaminants.
But PPB is still an enormous quantity. Remember Avogadro’s number (used to relate count to grams) is on the 10^23 scale (aka thousands of billions of trillions). Even 999 million is a drop in the ocean there.
EDIT: The journal abstract lists the leached nanoparticles as 10^9 (trillions) per mL, and the uptake by human-derived intestine cells as 100 micrograms/mL. So yeah this is coverage by a journalist who can’t math.
