It looked like it was a combination with that and the chemical they washed it with. Also, for this particular product, it isn’t healthy to use the sulfur treatment, it seems. The producers said something to the effect of, “we know this will cause problems for people, but the fruit is prettier and we get better prices for them”.
The news company said that they tested them as well and found them to be toxic.
I just read the 25 pages and they used a lot of hard data from China’s own databases, though the data is very limited access and particularly opaque even when compared to other regions according to the report, and it looks pretty compelling.
Edit: I’ll add that I’m changing my mind about it. I used to believe it, then I started to distrust it, but now I guess I’m coming back to it. What’s pretty wild is I’ve watched videos of people going to Xinjiang and it looks totally normal. Mosques everywhere, arabic text, people smiling, etc. Then on top of that it’s pretty clear that western capital wants to reduce China’s gains, so of course we’re happy at these reports.
But the quickest way to clear it up would be for China to let the UN come and look and interview people, but they aren’t. I do recognize that UN investigations tend to come with US spies, but I don’t really see what’s over there to hide, anyway.
I see these things all over Latin America and stayed at a bunch of places that have them. It can get SUPER hot. The cool thing about them is that the pipes that heat the water are vacuum sealed and don’t heat the water directly. I forget the exact mechanics of it, but it pretty much doesn’t matter what the temperature is. It can take that solar energy and add it to water.
