Widely used chemical *(that was generally phased out in the 70s) linked to Parkinson's. Still important, but you don't need to start searching product labels in 2023 for it.

If I remember right, the phase-out happened in the 1990s, just when a lot of manufacturing was leaving the U.S.

A few years back I found an internet search for “United States TCE” would turn up articles about Camp Jejune. A search for “China TCE” would turn up a picture of a truck with a bunch of barrels and an offer to buy it on Alibaba.

70% higher risk is meaningless if you don't give the absolute risk. Common issue with this kind of reporting... EDIT: my bad, they did talk about the absolute risk later on. Should have been the first thing they mention, though, to avoid looking sensationalist. > The researchers calculated the rate of Parkinson’s disease in the veterans and compared it with the rate in more than 72,000 veterans who lived at Marine Co…

> Should have been the first thing they mention, though, to avoid looking sensationalist. There isn't a whole lot they can do if you don't actually read the article. I always try to read the article before I pass judgement on whether it's sensationalized or not.

"After adjusting for differences in age, sex, race, and ethnicity, the scientists found veterans from Camp Lejeune had a 70% higher rate of Parkinson’s disease than the Camp Pendleton group." Why didn't they adjust for socioeconomic status? Wealthier people tend to be able to afford better medical care, live in healthier environments, eat healthier foods, etc. These could all be confounding factors, and a study like…

The problem with this study is even more profound.

They only looked at two military bases. One with high TCE, and one with low TCE.

...but there could be thousands of causal differences between two locations. They should have looked at dozens of military bases across the country/world.

Is that the only data sets they looked at? Comparing only two locations means that there could be any number of site differences that account for the difference in the rate of Parkinson’s disease, other than the studied chemical.

Pendleton seems to be a reasonable control, since the reported prevalence of 0.21% in patients under 60 matches other large data sets like the UK (0.25%).

Untrue.

Why would you drink coffee if not for the caffeine. It's not exactly the most delicious drink.

I don't understand this - If you don't enjoy the experience of drinking coffee, and just want the caffeine, then why not just take a caffeine pill?

Or you could drink an energy drink/sugar free cola instead.

It’s the reverse. People wanted decaffeinated coffee and the TCE stayed for the ride.

I have no clue what trichloroethylene is so I think the title is fair. It could be a stone for all I know.

A very effective organic solvent. Used in dry cleaning and formerly in chip making in SV.

It's also highly toxic, works as an anaesthetic (i.e., knocks you out); it also decomposes into phosgene and hydrochloride when exposed to light and air. But on the other hand, it is a great organic solvent.

This is a rather explicit use of the Naturalistic Fallacy. https://en.wikipedia.org/wiki/Naturalistic_fallacy

"The naturalistic fallacy should not be confused with the appeal to nature..." (3rd paragraph in your link)

Further down the article it explains that the terms have been used interchangeable for a long time. Language is a funny thing.
