What's the mechanism for photosynthesis reduction? It's not explained in the PNAS article nor the abstract of the original paper, which is a meta-analysis.

Do you mean the Calvin Cycle?
Edit: oof alpha channel moment
MP exposure reduces the chlorophyll content of photoautotrophs by 10.96 to 12.84%.
From the abstract of the paper OP linked
Yeah but that means what exactly? Plastic deposits on the surface of the plant? Water contamination? Something else?
¯\_(ツ)_/¯
Probably further research needed?
That's beside my point. They talk about the difference between photosynthesis efficacy with and without MPs, but don't explain how the MPs affect the process.
You don't have to explain the process to observe the difference. But it could be useful to understand the process to help figure out ways to mitigate it. I think we'll have to wait for future research to find that out though.
So that's what all this stuff is!
Also, could someone share a pdf?
I appreciate it!
But perhaps I should have been clearer.
I didn't mean Joanna Thompson's at Scientific American.
I was looking for Baoshan Xing's at PNAS.

No such thing with 3-rd party js disabled.
Ohh yeahh, forgot about that trick. TY!
Brawndo’s got what plants crave….
how do you reduce microplastics once they have seeped into the earth though?
Wooooooooooo all gas no brakes wcgw
Btw, those plastic foils are just plowed under, it's nuts. Make them bio-degradable already. The vegs shouldn't be allowed to be labeled "bio" if they use plastics for growing.
