No, that's not why you so often see reference to the defined safe level of toxins in water when talking about foods. FDA does not always have standards defined for levels of those toxins in food, but there might be a level defined by EPA for water. If you want an official, scientifically plausible number to fall back on, the level defined for water is at least something.
For example, FDA didn't have a defined safe level of arsenic in rice-based foods for infants until 2020, and there's still no defined safe level of for adults AFAIK. There's nothing mysterious about this: the ag industry lobbies against these standards, and lobbies to weaken them as much as possible when they exist. But babies are cute, so eventually FDA made a standard, at least for infants - after years of pressure from groups like Consumer Reports.
The paper referenced in the article says:
The U.S. Food and Drug Administration (FDA) has proposed an action level of 10 μg/L of inorganic arsenic in apple juice (USFDA, 2013).
which suggests that at the time of writing, there's isn't an official number defined by the FDA. Based on the language on the FDA's website [0] I assume "draft guidance" (which has been in existence as a "draft" for a decade) means producers won't be held accountable for exceeding the numbers there.

I suppose it is a decent fallback -but it's a reminder that regulatory frameworks could use some refinement!
Well first show me a politician that wants to get rid of the lobbyist system. The last one I heard of was Ron Paul over a decade ago.
BTW, I read of a better way to cook brown rice that reduces arsenic. Instead of 1 part rice, 2 parts water, simmer for 45 minutes, one does this:
1. Cook brown 1 part brown rice in 6 parts water for 30 minutes. 2. Strain to remove the water. Put rice in a steamer basket. 3. Steam for 10 minutes.
Much of the arsenic is carried away in the water in step 2. The rice also comes out much fluffier.

tl;dr - rinse your rice with clean water and then cook it at a ratio of 1:6 rice:water followed by draining the excess water will more than halve the amount of arsenic in the finished product
edit - tl;dr updated for accuracy

It might not be possible to kick both at once, but I feel like my life is better since switching mostly to coffee.
Good luck!
But to answer the question I believe that they are -- I still see periodic demonstrations of dissolving a full can of soda with acid leaving the soda contained (first yt hit: https://www.youtube.com/shorts/xIVONw9Pr4w)
