    Thanks Rob, but......any chance of some distillation of the relevant info? It would be useful to know which solvents etc are the nasty ones.

    The thrust of the paper is that titanium dioxide pigment sized particles have been found in the pancreases of diabetics but not non-diabetics. TiO2 is an ingredient (opacifier) in practically every residential paint. TiO2 is the white material in paint base. It may act as an inflammatory stimulus and thus exacerbate diabetes and potentially other health problems.

    The study is very small and thus should be considered a 'bad sign' until it is validated in a larger group. We also don't know if these observations are a cause or a consequence, i.e. are they chicken or egg, wrt the diabetic subjects.

    Interesting, my copy paste didn't work. Here's another try: https://pubs.acs.org/doi/abs/10.1021/acs.chemrestox.8b00047

    Works for me now. Sorry for that, don't know why it happened, I looked at the mistaken link a couple of days ago but somehow it carried over on my clipboard.

    Given what else its used for paints might be the least of our worries;
    From https://en.wikipedia.org/wiki/Titanium_dioxide
    It is widely used to provide whiteness and opacity to products such as plastics, papers, inks, foods, and toothpastes. Used in food applications, it whitens skim milk and adds flavors to soups, beer, and nuts.[60] It is also used in cosmetic and skin care products, and it is present in almost every sunblock, where it helps protect the skin from ultraviolet light.[61]

    Such are not the only particles either, you tend to find what you look for.

    You may be seeing a confounding effect of something else here...

    It turns out that the body will substitute "bad" minerals for "good" minerals when faced with a shortage of the "good" minerals.

    So stuff like Aluminum, Lead, Arsenic, and Titanium will substitute for Calcium when faced with a shortage.... And that causes all sorts of weird problems... Also because once that stuff gets used by the body - it sometimes doesn't leave easily...

    It wouldn't surprise me that this is some of what we are seeing here..... Kinda like how they found high concentrations of Aluminum in the brains of Alzheimer's patients... It's not aluminum frying pans or white paint.... It's a failure to get enough nutrients so your body doesn't use the nasty stuff....

    I suspect that the observations are an 'egg' not a chicken too. OTOH it wouldn't be the first time that the medical community missed something obvious - such are the hazards of non-scientists (physicians) practicing science.

    It's a problem of different disciplines not talking to eachother. But - as you and I both know - it's a very common problem.....

    These findings have all been tested and validated by the "Animal science" and "Plant science" guys... But you can do trials on hogs, cows, chickens, corn plants, and oak trees - and kill them or cause all sorts of cancers and birth defects "For Science"... You just go buy some more... People not so much.... And people live a *REALLY* long time compared to cats and rats...

    But for some reason - the "Medical Science" realm can't accept that people's bodies often work a whole lot like animal bodies... And you can learn a whole lot about absorbing bad things by witnessing ragweed plants uptake arsenic or mercury when they encounter a severe shortage of minerals like Calcium.... Or cows eating the plaster off barn walls to get calcium into their diets... Or ancient traditions of people "eating dirt" for this or that malady....

    But it points to one of the weird things about taking vitamins and consuming a "complete" diet.... It may not actually make you any "Healthier" (studies are generally pretty negative in that regard)..... But it *does* help prevent you from getting really sick when you come in contact with some of that bad stuff. Because you just tend to excrete it rather than it absorbing up into your tissues....

    Particles generally, not just TiO2.

    Diesel exhaust is a particular issue.
