...Relevant to Craig's observation, I understand how academics work. I was at the UMKC-SOM for 7 years. Advancement is dependent of publishing and obtaining grant money (inter-related). The folks paying for studies expect the results they hope for. But today, every article requires the authors to list any financial connections to those paying for the studies. And falsifying data is academic suicide. You'll be eventually caught, and teaching in a Jr. High the rest of your life.
Blood lead testing has been confirmed by erythrocyte protoporphyrin since the 70s, and can be performed in the field with a small (finger prick-like) sample. It has nothing to do with lead isotope analysis....
No, don't lock it, lol.
My purpose for introducing the medical spin on "peer review" was because it was presented as grail. I have seen peer reviewed articles in the AMA Journal and The Lancet, conclude that when random people go to an emergency room for medical care, that black ethnicity is medically relevant for cutting to the head of the line?
Back to steel shot, and related to your insights, should we expect a predictable conclusion when various branches of the department of the interior, commission "studies". Who are the peers who keep this science on topic? Someone probably has the numbers, but I'd guess it's likely the late1800's, since any gov study said, yes hunters/shooters have a point.
The isotope test were mentioned because it is seen as indisputable proof that the source of lead is neccessarily sporting shotgun lead shot. Of course, even the purpose driven authors of these papers, such as one you linked, must admit to inaccuracies and assumption, in a minimalist way. The Canadian study in your link said that weather likely carried massive amounts US generated combusted gasoline containing lead additive, north, but isotopes say it's impossible for an earthworm to ingest that variant. I would bet we could shoot lead paint chips, and that would be safe, because of how assumptions are made by worshipping the isotope. Something tells me, any time lead isotopes come up mixed source, blame the shogun pellet.
I'll edit to add that I added a like to your post, right next to the prof, simply for the purposes of noting that there is a difference between traditional science that can be repeated any where in the world with high predictability, and the science of emotional triggers. Now faith is entirely a different matter, and hopefully the secular progressive prof doesn't belittle the notion.
