=====Microplastics are everywhere: Is it possible to reduce our exposure?=====
[https://www.bbc.com/future/article/20240110-microplastics-are-everywhere-is-it-possible-to-reduce-our-exposure by Isabelle Gerretsen 6/3/24 BBC]
Microplastics have been found on every part of the planet. The tiny particles of this anthropogenic material have been found buried in Antarctic sea ice, inside the guts of marine animals inhabiting the deepest ocean trenches, and in drinking water around the world.
=====Your brain is full of microplastics: are they harming you?=====
[https://www.nature.com/articles/d41586-025-00405-8 by Max Kozlov 11/2/25 nature]
A sliver of human brain in a small vial starts to melt as lye is added to it. Over the next few days, the caustic chemical will break down the neurons and blood vessels within, leaving behind a grisly slurry containing thousands of tiny plastic particles.
=====Microplastics Are Filling the Skies. Will They Affect the Climate?=====
[https://e360.yale.edu/features/plastic-waste-atmosphere-climate-weather by Nicola Jones 1/2/23 YaleEnvironment]
Plastic has become an obvious pollutant over recent decades, choking turtles and seabirds, clogging up our landfills and waterways. But in just the past few years, a less-obvious problem has emerged. Researchers are starting to get concerned about how tiny bits of plastic in the air, lofted into the skies from seafoam bubbles or spinning tires on the highway, might potentially change our future climate.
=====Bioaccumulation of microplastics in decedent human brains=====
[https://www.nature.com/articles/s41591-024-03453-1 by Alexander J. Nihart 3/2/25 nature medicine]
Rising global concentrations of environmental microplastics and nanoplastics (MNPs) drive concerns for human exposure and health outcomes. Complementary methods for the robust detection of tissue MNPs, including pyrolysis gas chromatography–mass spectrometry, attenuated total reflectance–Fourier transform infrared spectroscopy and electron microscopy with energy-dispersive spectroscopy, confirm the presence of MNPs in human kidney, liver and brain.
=====How microplastics are infiltrating the food you eat=====
[https://www.bbc.com/future/article/20230103-how-plastic-is-getting-into-our-food by Isabelle Gerretsen 3/1/23 BBC]
Microplastics have infiltrated every part of the planet. They have been found buried in Antarctic sea ice, within the guts of marine animals inhabiting the deepest ocean trenches, and in drinking water around the world. Plastic pollution has been found on beaches of remote, uninhabited islands and it shows up in sea water samples across the planet. One study estimated that there are around 24.4 trillion fragments of microplastics in the upper regions of the world's oceans. 
=====Microplastics infiltrate human organs, raising health concerns=====
[https://www.ehn.org/microplastics-infiltrate-human-organs-raising-health-concerns by EHN Curators 27/2/25 EHN]
In 2024, toxicologist Matthew Campen discovered that the adult human brain contains about a disposable spoon's worth of plastic, a 50% increase from eight years prior.
Studies have found microplastics in human tissues such as placentas, breast milk, and semen, suggesting widespread infiltration of our bodies.
Research indicates potential links between microplastic exposure and health issues like cardiovascular disease, reduced sperm count, and certain cancers.
=====Microplastics are in our bodies. How much do they harm us?=====
[https://www.nationalgeographic.com/environment/article/microplastics-are-in-our-bodies-how-much-do-they-harm-us by Laura Parker 8/5/23 NATIONAL GEOGRAPHIC]
A few years ago, as microplastics began turning up in the guts of fish and shellfish, the concern was focused on the safety of seafood. Shellfish were a particular worry, because in their case, unlike fish, we eat the entire animal—stomach, microplastics and all. In 2017, Belgian scientists announced that seafood lovers could consume up to 11,000 plastic particles a year by eating mussels, a favorite dish in that country.
=====How do microplastics impact our gut health?=====
[https://www.ehn.org/microplastics-and-gut-health by Allison Guy 6/10/23 EHN]
Nowadays, nearly all of our meals come seasoned with a flurry of tiny plastic particles and fibers. Scientists don’t know exactly how much we consume, but estimates range from five grams a week – the weight of a credit card – down to a minute fraction of that. Weight, however, isn’t all that matters. Exceptionally tiny fragments, as small or even smaller than a single bacterium, can penetrate human cells and pass from the gut to the bloodstream.
=====Microplastics block blood flow in the brain, mouse study reveals=====
[https://www.nature.com/articles/d41586-025-00178-0 by Smriti Mallapaty 23/1/25 nature]
For the first time, scientists have tracked microplastics moving through the bodies of mice in real time1. The tiny plastic particles are gobbled up by immune cells, travel through the bloodstream and eventually become lodged in blood vessels in the brain. It’s not clear whether such obstructions occur in people, say researchers, but they did seem to affect the mice’s movement.
=====How a microplastics researcher avoids plastic in daily life=====
[https://www.ehn.org/how-a-microplastics-researcher-avoids-plastic-in-daily-life by HN Curators 23/7/25 EHN]
Plastic fragments have infiltrated air, water, soil, and food chains worldwide, entering human bodies through what we eat, drink, and breathe. Research shows they lodge in vital organs and can disrupt hormones, impair fertility, and fuel inflammation, yet their long-term health impacts remain poorly understood.
=====The distribution of subsurface microplastics in the ocean=====
[https://www.nature.com/articles/s41586-025-08818-1 by Shiye Zhao 30/4/25 nature]
Marine plastic pollution is a global issue, with microplastics (1 µm–5 mm) dominating the measured plastic count1,2. Although microplastics can be found throughout the oceanic water column3,4, most studies collect microplastics from surface waters (less than about 50-cm depth) using net tows5. Consequently, our understanding of the microplastics distribution across ocean depths is more limited.
=====Microplastic research must consider microbes=====
[https://www.nature.com/articles/s41564-025-01960-6 by Nature Microbiology 5/3/25 nature microbiology]
It is increasingly clear that microplastic pollution can be detrimental to human, animal and environmental health. More research is needed to determine if and how our microbial partners are also negatively impacted, and what this means for host and ecosystem health.
=====What scientists have learned from 20 years of microplastics research=====
[https://grist.org/science/20-years-microplastics-research-pollution-health-environment/ by
Joseph Winters 20/9/24 Grist]
Twenty years ago, a team of U.K. scientists sounded the alarm on a then-underappreciated problem: the breakdown of plastic litter into small, even microscopic, fragments. While many previous reports had documented the buildup of plastic bottles and bags in the natural environment, much less attention had been paid to what the scientists dubbed “microplastics.”
=====Microplastics and pollution combine to become much more toxic: Study=====
[https://www.ehn.org/are-microplastics-toxic by Krystal Vasquez 18/4/22 EHN]
Although the dangers of both microplastics and harmful compounds have been studied individually, few researchers have look at their combined effect. This study is also unique in that the researchers tested these polluted plastic particles on human cells—most previous research has focused on the impacts on marine life.
=====Who Said Recycling Was Green? It Makes Microplastics By the Ton=====
[https://insideclimatenews.org/news/16052023/recycling-plastic-microplastics-waste/ by James Bruggers 16/5/23 Inside Climate News]
A study finds one plastics recycling plant in the U.K. produces as much as 3 million pounds of microplastics a year—and that’s with filtering.
=====Microplastics generated when opening plastic packaging=====
[https://www.nature.com/articles/s41598-020-61146-4 by Zahra Sobhani 19/3/20 scientific reports]
Millions of tonnes of plastics have been released into the environment. Although the risk of plastics to humans is not yet resolved, microplastics, in the range of 1 μm - 5 mm, have entered our bodies, originating either from ingestion via the food chain or from inhalation of air.
=====Microplastic particles in human blood and their association with coagulation markers=====
[https://www.nature.com/articles/s41598-024-81931-9 by Dong-Wook Lee 6/12/24 scientific reports]
Recent studies have indicated potential health risks associated with microplastics (MPs) exposure, including alterations in blood coagulation homeostasis. This cross-sectional study aimed to quantitatively examine MPs in human blood and assess their association with coagulation markers.
=====Microplastic hotspots mapped across the Southern Ocean reveal areas of potential ecological impact=====
[https://www.nature.com/articles/s41598-024-79816-y by Aidan Hunter 30/12/24 Scientific reports]
Marine microplastic is pervasive, polluting the remotest ecosystems including the Southern Ocean. Since this region is already undergoing climatic changes, the additional stress of microplastic pollution on the ecosystem should not be considered in isolation.
=====Stand Up to Plastic=====
[https://www.nature.org/en-us/about-us/where-we-work/united-states/california/stories-in-california/stop-plastic-waste/ by stories in California 5/5/25 The Nature Conservacy]
Microplastics are largely invisible to the naked eye, but they pose a major threat to people and the planet. These tiny fragments of plastic are less than five millimeters in diameter but collectively, they make up about a third of the plastic in our oceans. Microplastics have been found from the heights of Mt. Everest to the deepest ocean trenches.
=====Food contact articles as source of micro- and nanoplastics: a systematic evidence map=====
[https://www.nature.com/articles/s41538-025-00470-3 by Lisa Zimmermann 25/5/25 npj]
Micro- and nanoplastics (MNPs) in foodstuffs lead to widespread human exposure and are often linked to environmental contamination. However, the role of plastics in food contact articles (FCAs) has received less attention, despite being a known source.
=====Environmental impacts of biodegradable microplastics=====
[https://www.nature.com/articles/s44286-024-00127-0 by Zhengyin Piao 27/9/24 nature chemical engineering]
Biodegradable plastics, perceived as ‘environmentally friendly’ materials, may end up in natural environments. This impact is often overlooked in the literature due to a lack of assessment methods.
=====You’re eating, drinking, and breathing microplastics. Now what?=====
[https://massivesci.com/articles/microplastic-straws-single-use-plastic-pollution-ban-canada/ by Anna Robuck 14/6/19 MASSIVE SCIENCE]
A new study led by Kieran D. Cox and researchers at the University of Victoria in British Columbia confirms a logical but cringe-worthy conclusion: humans are consuming plastic. The researchers estimate that humans are eating about 250 pieces of microplastic per day, or roughly 94,000 microplastics in a given year. The average amount consumed varies with age and gender, but the basic premise remains.
=====The Plastics Crisis: A Neuropsychiatric Problem Hidden in Plain Sight=====
[https://www.psychiatrictimes.com/view/the-plastics-crisis-a-neuropsychiatric-problem-hidden-in-plain-sight by Elizabeth Ryznar 3/9/24 Psychiatric Times]
The impact of plastics on health is an area of increasing concern. Plastics specifically affect brain health and development, which is why psychiatry must pay attention to the growing plastics crisis.
=====Microplastic pollution found in insect casing from 1971=====
[https://www.nature.com/articles/d41586-025-01265-y by Shamini Bundell 17/4/25 nature]
Tiny particles of plastic are everywhere today, but a discovery in a museum collection proves that this isn’t a new phenomenon. While combing through drawers of caddisfly specimens, researchers found evidence of microplastic particles being used as a building material by caddisfly larvae as far back as the 1970s and 1980s.
