The percentage of PET of plastic does not have a citation

Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).[citation needed]

This is a very specific claim. On the Wiki page "Plastic" (https://en.wikipedia.org/wiki/Plastic#cite_note-Geyer2017-23) it is stated that PET makes up 8.1% of global plastic production. Which one is correct? How did they get 18%? 2804:14C:5BD6:9613:5440:7BA8:FB31:97CF (talk) 17:20, 31 October 2023 (UTC)[reply]

Which is to say they both are not correct? Need to be sure are comparing apples to plastic apples here--same year, same way of measuring (volume, mass, amount of carbon, etc) and that its raw stock production, not total amount (which has a variable amount of recycled esp. polyester) and that its all global or at least from same market / region and properly qualified.

Lack of citation in "Littering" section

"Nevertheless, littering has become a prominent issue in public opinion, and PET bottles are a visible part of that."

Call it WP:BLUE but I feel this is claim is atleast decently large enough to require atleast one or two citations, both in regards to calling it a "prominent issue in public opinion" and that "PET bottles are a visible part of that"

Not particularly doubting the claims, however blue they may be, made here but atleast one citation would do this sentence good. 62.182.223.128 (talk) 08:43, 10 April 2024 (UTC)[reply]

ALERT: Microplastics and Nanoplastics may cause increased risk of Cardiovascular Events!

"Microplastics and NanoPlastics (MNPs) are emerging as a potential risk factor for cardiovascular disease in preclinical studies.

Polyethylene was detected in carotid artery plaque of 150 patients (58.4%), with a mean level of 21.7±24.5 μg per milligram of plaque.

Patients in whom MNPs were detected within the atheroma were at higher risk for a primary end-point event than those in whom these substances were not detected (hazard ratio, 4.53; 95% confidence interval, 2.00 to 10.27; P<0.001)".

... We don't know yet where this Polyethylene comes from. Eeaten/drinked, or inhaled. And is the risk because of plastic, or because people drink soft drinks which are not healthy.

Scare talk

The following hefty section could be condensed to a sentence. "Antimony Antimony (Sb) is a metalloid element that is used as a catalyst in the form of compounds such as antimony trioxide (Sb2O3) or antimony triacetate in the production of PET. After manufacturing, a detectable amount of antimony can be found on the surface of the product. This residue can be removed with washing. Antimony also remains in the material itself and can, thus, migrate out into food and drinks. Exposing PET to boiling or microwaving can increase the levels of antimony significantly, possibly above US EPA maximum contamination levels.[56] The drinking water limit assessed by WHO is 20 parts per billion (WHO, 2003), and the drinking water limit in the United States is 6 parts per billion.[57] Although antimony trioxide is of low toxicity when taken orally,[58] its presence is still of concern. The Swiss Federal Office of Public Health investigated the amount of antimony migration, comparing waters bottled in PET and glass: The antimony concentrations of the water in PET bottles were higher, but still well below the allowed maximum concentration. The Swiss Federal Office of Public Health concluded that small amounts of antimony migrate from the PET into bottled water, but that the health risk of the resulting low concentrations is negligible (1% of the "tolerable daily intake" determined by the WHO). A later (2006) but more widely publicized study found similar amounts of antimony in water in PET bottles.[59] The WHO has published a risk assessment for antimony in drinking water.[58] Fruit juice concentrates (for which no guidelines are established), however, that were produced and bottled in PET in the UK were found to contain up to 44.7 μg/L of antimony, well above the EU limits for tap water of 5 μg/L.[60]"--Smokefoot (talk) 15:23, 19 January 2026 (UTC)[reply]
