Most people are surprised how much microplastic comes from everyday items like water bottles, food containers, and clothing.

What's one product you've already switched away from plastic?

@thedailymeal Enameled cast iron is a solid move for anyone getting off nonstick: no coating to scratch off, and the enamel handles tomato sauce and wine that strip seasoning on bare cast iron. Just retire it if the enamel chips on the cooking surface.

@StuffKeithBuys $20 and scrub it. Steel wool, wash, dry it on the burner, thin coat of oil, bake. Surface rust is cosmetic; cracks or deep pitting are the deal breakers. An old cast iron pot is one of the best coating-free pans you can own.

@YVWD Love seeing a water district mention microplastics alongside the recovery numbers. Membranes screen particles by size, which is why they're one of the few treatment steps that actually catch them. Will you be tracking particle counts before and after?

Cutting boards at #1 has real data behind it: an NDSU study (ES&T 2023) estimated 14.5 to 71.9 million polyethylene microplastics per person a year from PE boards, about 79.4 million from polypropylene. Easiest swap on the list. We compared wood options here: https://t.co/9ReAUtydIJ

@ben19075510 Fair 😅 Preheat the cast iron properly and use a little fat and eggs get way easier. If you keep the nonstick, low-medium heat and wood or silicone utensils help the coating last, since scratches are when it starts shedding.

[WhatisMicroplastics @NonToxicSwaps]

@grizzlewdg2 @YouTube Agree on cast iron and stainless. With any coated pan, the surface is the tell: once it's scratched or flaking, retire it first. A 2022 Flinders University study estimated a single surface crack in a PTFE pan can release around 9,100 particles.

@Cancernetuk Worth adding the nuance from the NIH Sister Study: the link showed up for ER-negative tumors, not breast cancer overall, and it's observational. The most practical step for most people is still checking your local water report for PFOA/PFOS.

[WhatisMicroplastics @NonToxicSwaps]

@NJBIZ If you do get a PFAS blood test, the National Academies' 2022 guidance is the yardstick: it uses the sum of 7 PFAS. Under 2 ng/mL, no effects expected; 2 to 20, potential risk, so cut exposure; 20+, extra screening. They estimated about 98% of Americans are above 2.

Where do you feel most stuck right now: drinking water, cookware, food storage, laundry, or kids' products? Say which one and I'll try to be useful.

[WhatisMicroplastics @NonToxicSwaps]

Closest thing so far: a 2026 Journal of Clinical Apheresis study found plasma exchange lowered blood microplastic counts, but only in people starting with higher levels. In low-level patients counts actually rose, because the plastic tubing leached particles in. For now, cutting intake (less heated plastic, filtered tap) is the lever we have.

[WhatisMicroplastics @NonToxicSwaps]

The number that stuck with me: Highlands Biological Station caught over 10,000 microplastics per square meter during the three days of Helene, close to 20% of its roughly 55,000 for the whole year. One stream site moved over 70 billion particles an hour. And lots of blue fibers, which points straight at clothing.

The 30:49 chapter is the one I'd send people to. Easy place to start: when buying a couch, rug or curtains, skip the optional stain- or water-repellent treatment, since EPA lists those finishes as a PFAS source in homes. Then HEPA vacuum and damp dust, because household dust is one of the ways it gets in.

[WhatisMicroplastics @NonToxicSwaps]

Useful number while this plays out: the federal limit for PFOA and PFOS is now 4.0 parts per trillion each. Utilities have until 2029 to meet it (EPA has proposed up to 2031 for some), so your utility's annual water quality report is the quickest way to see where your tap stands today.

[WhatisMicroplastics @NonToxicSwaps]

Per the story, DEQ flagged nearly 40 changes and Chemours has 60 days to respond. For families on private wells in southeastern NC, the practical step while that plays out is getting the well tested, and if you filter, checking that the model's NSF/ANSI 53 or 58 listing names PFOA and PFOS reduction.

[WhatisMicroplastics @NonToxicSwaps]

One detail from that 2026 Journal of Clinical Apheresis study worth adding: across 174 exchanges in 114 patients, net removal showed up at higher starting levels. In patients starting at 0 to 9 particles per 100 µL, the average went up after TPE (about 4.4 to 14.4) because the plastic tubing and fluid bags leached particles in. The authors call it a first demonstration, so cutting intake still matters.

@Jairus_Girl @Ferndiggity Wanting to be buried with it is the best review a French press can get 😄 The all-steel ones really are the buy-it-once kind.

[WhatisMicroplastics @NonToxicSwaps]

I don't have brand-level results for it, and ANSES didn't publish brand names. What they did find: water was the low end no matter the container, about 4.5 particles per liter in glass vs 1.6 in plastic bottles and cartons. The ~100 per liter numbers were sodas, iced tea and beer with painted metal caps.

The one we'd grab: the Instant Pot Duo 7-in-1 (6 qt). It slow cooks in a bare 18/8 stainless inner pot with no coating (the lid does use a silicone sealing ring). Heads up: its slow-cook mode runs cooler than a classic crock, so give recipes extra time.

Slow cooker season, so take a quick look inside yours.

Most crocks are glazed ceramic. A well-made glaze from a regular manufacturer is fine. A chipped, crazed or worn one is worth retiring. The FDA lists damaged or excessively worn ceramicware among its "problem types" for leachable lead, and chili sitting in there for 8 hours is exactly when you want that glaze intact.

Nonstick-coated inserts are the other one to watch. Once they start flaking, the flakes end up in dinner.

A bare stainless insert skips both questions.

The pans we'd swap to, stainless and cast iron included: https://t.co/csZn8OVH52

This is why PFAS feels impossible: it's not one chemical, it's thousands, and it's in stuff we use every single day. You can't fix all of it. But you can fix the pan you cook on every morning. If your nonstick is scratched or flaking, retire it today and swap in stainless or cast iron. One change, zero effort after that.
