Being lazy here, but would love to know more about how testing for all of these plastics chemicals that are omnipresent is done in a way that ensures the measurement process or tools themselves do not contribute trace chemicals (e.g. lab tech wears latex gloves while handling the sample, whoops, etc).

They go into significant detail about their sample handling as well as documenting potential sources of contamination here: https://www.plasticlist.org/methodology

Nice and thank you! Will now go head my head in shame for not having bothered to click the “menu” icon on the main report :facepalm:

The boba tea result alone makes me want to never drink that again. Was a fun little treat while it lasted…

It seems noteworthy, but not commented that I can see (in the article), that the different samples of "Boba Guys Black Tea Pearls" have 20x variation in measured amount. So what's up with that? (I have uninformed ideas...)

This seems to be the happening with other items and chemicals tested as well. Look at the results for DNP in Clover organic milk for example.

I've been using a reverse osmosis water filter at home to reduce microplastics and other contaminants from my drinking and cooking water for the past few years. I am using the #1 recommended product on Buyer's Guide[1] for others who are interested. [1] https://buyersguide.org/countertop-reverse-osmosis-system/t/...

I’m not familiar with this buyers guide site. Is it critical rankings by a human or some sort of automatic ranking / SEO spam?

I tried reading their review. It was completely vacuous.

This isn’t a real review site. It’s an SEO trap for affiliate revenue. I thought HN readers could spot these affiliate spam sites, but I guess not everyone is on to this scam.

Are there prospective studies on effects? Afaik it's just in vitro, and I wonder if our bodies have a natural mitigation mechanism that would allow up to a certain amount without harm. I'm just afraid of what I see as a trend to attribute small factors to big things that are caused by societal problems, etc.

I am, in a different life, a consumer of compost and I have started looking very carefully at the compost products for sale in the bay area. On the urban consumer side of things I see compost collection bins which cannot possibly be decontaminated of all manner of plastic pieces which will, inevitably, be ground up into the compost product. On the rural side of things I see miles of plastic baling twine and weedeater…

I’m usually less worried about microplastics than many (human lifespan is at the longest it’s ever been, and people are healthy at older ages than ever - things can’t be that bad overall), but weed eater string is a pet peeve of mine. We’re just spewing nylon microplastics everywhere, and I can’t understand how it’s not at all controversial!

Ice cream strikes me as a lot healthier than boiled play-doh.

Ben & Jerry’s Cookie Dough has ~25g sugar per 100g. Boba has ~14g per 100g, depending on the type. Coca Cola has ~11g sugar per 100g. In other words, ice cream has 1.8x more sugar content than boba and 2.3x more sugar content of Coca Cola. If you’re concerned about the tapioca, that’s literally just starch. You know what else contains starch? Potatoes and rice.

> Ben & Jerry’s Cookie Dough has ~25g sugar per 100g. Boba has ~14g per 100g, depending on the type.

Nothing at Boba Guys weighs 100g. That's the difference! 100g really is a typical cup of gelato or ice cream.

Reverse osmosis leaches microplastics (because of the membrane):

I guess it’s possible to distill the water and add clean minerals back in. (Not sure if “clean minerals” are something that you can obtain though.)

Honestly what else are you going to make it out of? Metal? What about rust? Horrible idea to make it out of metal.

Is this sarcasm? Rust is fine to consume, but there are also metals that don’t corrode in water.

Semipermeable osmatic membranes cannot be made out of metal
