Analysis of samples of AGC’s effluent revealed levels of PFOA as high as 12,000 nanograms a litre in 2021.
What in buggery is a nanogram?
(NA-noh-gram) A measure of weight. One nanogram weighs a billion times less than one gram, and almost a trillion-times less than a pound.
A billion of a gram, or a trillionth of a kg therefore. A litre of water is a kg.
12,000 parts per trillion. Or 12 parts per billion.
Until perhaps 20 years ago we very rarely ever measured anything in lower concentrations than parts per million – ppm. Now here the squinnying is about 12 ppb?
Hmm, it might just be that greater possibility of measurement that’s the issue here, no? N0ot necessarily so, but we’d certainly want to consider it as the issue, no?
but the EU is considering imposing standards of 4.4ng/l of PFOA equivalents
4.4 ppt? Really?
He added: “More appropriate research and funding is desperately required
Nope, didn’t see that coming.
Even as this might be true:
PFOA, one of the most-studied substances in the group, has been strongly linked to a wide range of diseases, including testicular and kidney cancer, thyroid disease, hypertension and ulcerative colitis. It has also been linked to high cholesterol, low birth weight, reduced immune function and developmental problems.
Yes, but at what concentrations? Paracelsus Dear Boy, Paracelsus.
