If you're old enough to remember, it's a little unsettling and strange. (lemmy.world)

The runoff levels are tested to be in the nM range, but they’re applying 10-50 mM to each insect directly injected. Even if they’re in the field and encountering mM concentrations as applied, contact with an insect probably isn’t going to transfer much to the bloodstream as there’s no direct transfer pathway for animals.

wouldn't the primary technicality here be exposure time? Rather than exposure levels. Ultimately depends on the lifespan of the insect itself. But this is a pretty significant factor to why things like leaded gas got banned.

Presumably. Also would be determining a pathway that gets those low concentrations through to the organism in levels high enough to induce the effects that they've determined with artificial exposures. But that's not even hinted at in the study, and that's usually where these studies fail.

I can introduce high levels of NaCl to a cell and kill it, but without finding a way that dunking someone in seawater kills them via mere exposure, saying the ocean is hazardous is a bit of a stretch.

uhm, drowning, hypothermia, being stranded in the middle of it. I can think of a few.
