I was curious if the micro-plastics could be coming from the bottles they are packaged in. The article says... It's not clear how the plastic is getting into the bottled water — whether it's the water source itself or the air or the manufacturing and bottling process. "Even the simple act of opening the cap could cause plastic to be chipping off the cap," Mason said. I think it's easy to assume it's from the water so…

> This also makes sense to me since San Pellegrino has the lowest profile, and often comes in glass.

No mention of which variant(s) (glass, plastic, both?) were tested, right? (or I haven't been able to find the statement)

My suspicion would be that at least some of the plastic particles are coming from the bottles themselves. Plastic degrades over time, so this would not be too surprising.

Right, I'm curious is some of the outliers at the high end were from older bottles that had been on the shelf longer.

Went looking to see what the comparison to tap water was: > Orb found on average there were 10.4 particles of plastic per litre that were 100 microns (0.10 mm) or bigger. This is double the level of microplastics in the tap water tested from more than a dozen countries across five continents, examined in a 2017 study by Orb that looked at similar-sized plastics. Worse... it's worse than tap water.

In at least a couple of European countries it is well known that unless your city has specific problems tap water is better than bottled water.

The reason being that (except some cases of corruption...) legal limit are much stricter for tap water.

Better in impurities at the very least, the taste is usually quite worse.

I wonder if pelligino is very low because it's bottled mineral water

Where I live they are all glass bottles, so I am not sure how plastic enters in the first place.

Yeah, I was under the impression they only came in glass so the fact that they have the lowest amount of plastic could implicate the bottle itself as the primary source.

Perhaps the low amount in SP is from that seal in the bottle cap?

I didn't notice any mention. Just a guess though, I've seen S. Pellegrino in plastic so it's possible theirs were.

While less common, San Pellegrino does come in a plastic bottle. I’m curious why they didn’t include the packaging in the graphic of the brand breakdown linked elsewhere, seems like this is a super relevant variable.

Just fyi in Switzerland I see the two main supermarkets (Migros & Coop) selling it only in plastic bottles.

None of these brands are known to me but I believe I've seen San Pelegrino in the south of Europe, the balkans. Iirc their bottle is a thick stiff bottle type, of the same type that my favorite bottled mineral water Ramlösa uses. Maybe someone could confirm this. Whenever I see bottled water in american TV it's always that cheap wrinkly bottle. That type is always cheaper here in Sweden. Depending on where you get it…

San Pellegrino is an italian brand, and it's quite common in Europe, not just in the south. Most of the time, you'll find soft drinks from that brand rather than water, though.

Edit: Was an italian brand until Nestlé bought it, it seems.

Or perhaps if they were exposed to heat, oxidation, or physical stress even (dropped, squeezed, overly pressurized)
