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 (billions) 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.
