Realistically, the best thing you can do to reduce your microplastics intake seems to be to avoid microwaving in plastic bowls and to avoid using plastic bottles for soft drinks and water. (Though cans actually use a thin film of plastic inside too.. so, maybe just avoid packaged water?) Beyond your personal intake though there's bigger fish. Car tyres are the #1 source for microplastics entering rivers, and it's not…

The article says this is probably wrong. We breathe in much more.

I wonder when and if microplastics will get it's Asbestos moment. Obviously they are not as carcinogenic, but it seems we don't have the full picture, and microplastics are present at an insanely higher degree than asbestos where.

Given the fact that they are so ubiquitous and yet no causal relation between microplastics and any health issue whatsoever has been identified in any rigorous study until today [1], I'd say a lot of this reporting is fear mongering by the eco/organic industry, aimed at gullible people who know very little about science. Not as insane and unphysical as electro smog, but definitely nowhere near asbestos. The linked ar…

> BPA is a known endocrine disruptor. Although initially considered to be a weak environmental estrogen, more recent studies have demonstrated that BPA may be similar in potency to estradiol in stimulating some cellular responses.

> In 2017 the European Chemicals Agency concluded that BPA should be listed as a substance of very high concern due to its properties as an endocrine disruptor.[30] In 2023, the European Food Safety Authority re-evaluated the safety of BFA and significantly reduced tolerable daily intake (TDI) to 0.2 nanograms (0.2 billionths of a gram), 20,000 times lower than the previous TDI from 2015.

> In 2012, the United States' Food and Drug Administration (FDA) banned the use of BPA in baby bottles intended for children under 12 months.[31] The Natural Resources Defense Council called the move inadequate, saying the FDA needed to ban BPA from all food packaging.

> This followed another paper in early 2024, where a group of Italian researchers identified microplastics in plaques found in the carotid arteries – a pair of major vessels which deliver blood to the brain – of people with early-stage cardiovascular disease. This linked their presence to worsening disease progression. Over the following three years, individuals carrying these microplastics in their plaques had a 4.5-fold greater risk of stroke, heart attack or sudden death.

> Then in February 2025, another group of scientists identified microplastics in the brains of human cadavers. Most notably, those who had been diagnosed with dementia prior to their death had up to 10 times as much plastic in their brains compared to those without the condition. "We were shocked," says Matthew Campen, a University of New Mexico toxicology professor who led this study.

One action doesn't obviate the need for another.

Also, stop using dishwashing pods and laundry pods with the dissolvable plastic layer encasing them. Use powder or liquid detergent instead. If you can't find it in store, look for it online, because it definitely is in stock.

https://archive.ph/UcCq6 Saying HEPA filters remove "99%" of microplastic is pretty misleading. Most of the mass in airborne particles is in the larger sizes of visible dust. However these particles will "fall out" before they reach the air purifier. The best advice isn't "use only HEPA" or (an odd one, from this article) "use filters with multiple stages," it's to have an air purifier where the Clean Air Delivery Ra…

> Most people dramatically under-size their air purifiers, or run them on a very low fan setting, and then they throw up their hands and just say that air purifiers don't work.

I believe something is better than nothing here. One of the biggest complaints against air filters is noise so maybe a good compromise would be to run them at full speed and full noise for a certain amount of time or something when nobody is in the room?

  >microwaving in plastic bowls
More generally, never let hot food touch plastics. The high temperature is what damages the plastic surface, not anything special about microwaves.

For instance the same thing happens with plastic tea bags in hot water: https://www.sciencedirect.com/science/article/pii/S004565352...

Curious why you say this when the linked article says the best thing you can do is avoid synthetic textiles

the article lists several things including textiles, plastic packaging, and avoiding tyre particles. I led with containers/bottles because that's where the most concentrated single exposures seem to be (microwaving in plastic, bottled water), but you're right that textiles are up there too, especially for airborne microfibres.

The exposure from food packaging is many times more prominent than polyester, which slows down leeching over time.

There’s a big difference between nanoplastics/chemical leeching (which is what happens with heated food containers) and microplastics of the sort that break off from clothing other plastic materials (which is what the article is talking about). Both are significant issues though.

The way to get air purifiers to really work well is to install them at the air intake, i.e. in the windows, or where the central air intake is, so all incoming air passes through them. I use indoor air purifiers too, but not as a substitute for ones at the intake. Note that tires and diesel fumes are prominent neighborhood sources of harmful particulates.

It is not expensive to run intake fans in the spring and fall seasons when active heating or cooling are not required.
