boiling precipitates the water's minerals onto the microplastic, making it bigger (and easier to filter)
that's why it works better with hard water than soft
ok I just found out there actually was a study link, on the caption of the 2nd picture
most of the time these articles never even include it, but even this one could just be linked at the very top
There was a microplastics article a year ago which warned people not to drink rainwater due to the microplastics in the air (made no mention of how that compares to natural MP concentration in tap water)
5x longer than it needs to be
Compare:
A greater concentration of NMPs was removed from samples of hard tap water, which naturally forms a build-up of limescale (or calcium carbonate) as it is heated. Commonly seen inside kitchen kettles, the chalky substance forms on the plastic's surface as changes in temperature force the calcium carbonate out of solution, effectively trapping the plastic fragments in a crust.
Even in soft water, where less calcium carbonate is dissolved, roughly a quarter of the NMPs were snagged from the water. Any bits of lime-encrusted plastic could then be removed through a simple filter like the stainless steel mesh used to strain tea, the researchers say.
to my edit:
more NMPs were filtered from hard water than soft, because the limescale in hard water naturally accumulates on NMPs, making them bigger and easier to filter.
Article has:
every cracker article is like this
true, except
crackers never take into account "resources per capita" or "food/land per capita" because it would demolish their narrative
it really does look like a zombie apocalypse rare critical support to Hummers and other oversized American cars
TIL that you can just copy and paste random shit from Libreoffice.
how are you getting your libreoffice calc tables to look like that
also that moment when Europe scores lower than India
This method is the best method, but it still doesn't control for having larger populations to choose from. Which is pretty irrelevant in China vs. USA but still relevant in China vs. Slovomoldslavia or whatever
Cracker 1: "only 7% of Americans actually own houses. how can we spin this into a positive?"
