Definition[edit]

The definition of microplastics, less than 5 mm dia, is illogical, considering all polymers leaving Polymerisation Factories are small beads that fall into this category. Most are 2- 3 mm dia by 4mm long,prior to processing. This definition condemns all Polymers to the "fear" of microplastics ingestion, when in fact the problem is a waste management issue that has been around for centuries.The world wide practice of dumping rubbish in the Ocean rivers creeks has now been exposed because a large percentage of plastics float, unlike steel cans and glass bottles that sink. — Preceding unsigned comment added by 118.82.147.188 (talk) 20:11, 1 February 2023 (UTC)[reply]

Intro to Policy Analysis Critique[edit]

A. Most of the facts have reliable sources but some of the facts come from sites that could be interpreted as biased or unreliable.

C. The article remains neutral because it seems that its main focus is to educate readers on the nature of microplastics as well as where it comes from.

G. A lot of the information is recent so not much needs to be updated, however, there are some sources from the 20th century and would most likely need to be updated. Due to the nature of the plastic pollution, it is important that the resources remain updated so I would try to keep the cited works as recent as possible.

citation[63]does not apply to the said contents, and an obvious error related to treatment plant discharge[edit]

Instead, citation [64] applys to the contents intended by [63]. And "Considering that one treatment plant discharges 160 trillion liters of water per day, around 8 trillion microbeads are released into waterways every day", the numbers in bold are related to the United States as a country, not one treatment plant. ThomasYehYeh (talk) 10:40, 22 January 2023 (UTC)[reply]

I found the same mistake. I don’t understand the calculations of the referenced text, but I removed the incorrect citation and the obviously wrong “160 trillion liters per plant and day”. 37.138.102.85 (talk) 16:23, 15 March 2023 (UTC)[reply]

Microplastic particles in human body[edit]

The #Human body section (permalink) collects a bunch of unrelated papers reporting random findings of microplastic particles. Such statements have clear (non-necessarily intentional) scaremonger effects on the reader, while there is no general consensus neither about how microplastics are widespread in the human body or in average human food, nor about how dangerous this presence would be. Horcrux (talk) 10:32, 7 October 2023 (UTC)[reply]

The #Humans section has a statement about the lack of consensus. Makes me wonder why the two sections are in completely different parts of the article. HansVonStuttgart (talk) 12:08, 10 January 2024 (UTC)[reply]
