Great Lakes microplastics study aims to spur tougher plastics rules

Researchers at the Experimental Lakes Area seed Lake 378 with microplastics to study their fate, transport, and entry into the food web, part of a broader effort to push monitoring and policy action across the Great Lakes; the work, along with a growing body of evidence that microplastics are widespread in the basin, has spurred calls for stronger regulation and binational cooperation, even as local pollution issues—like Sarnia's Chemical Valley emissions and nurdle pollution—highlight ongoing health and environmental concerns.

Cholesterol-filter Therapy May Also Sweep PFAS and Microplastics From Blood

Therapeutic apheresis, a blood-filtering therapy for lowering lipoproteins in severe cardiovascular disease, was found in small studies to also reduce circulating PFAS levels—up to 25% after one session in one protocol and 43.5–75.8% across five PFAS in another—while microplastic results were mixed and subject to measurement challenges. Researchers caution that these are exploratory, with small sample sizes and methodological differences; there is no proven reduction in total body PFAS or microplastics burden, and more controlled trials are needed before considering apheresis as a pollutant detox.

Today’s Everyday Things, Tomorrow’s Health Hazards: Readers Predict the Next Asbestos

A BuzzFeed Community post collects readers’ predictions about which everyday items and habits could be proven harmful in the future, ranging from microplastics and PFAS to AI-driven social media, scented products, vaping, and long-term effects of COVID, highlighting concerns about environmental exposures, consumer goods, and modern lifestyles becoming health risks down the line.

Blood filtration may also scrub 'forever chemicals' from the body, study finds

A study of plasmapheresis, a blood-filtering technique used to lower cholesterol, found that it also reduced levels of several PFAS 'forever chemicals' and microplastics in patients’ blood, with PFAS dropping up to about 25%. However, the results are not yet proven in a controlled trial, and researchers caution that preventing exposure remains the primary solution while further research is conducted.

Microplastics Found in Every Artery Sample, Study Raises Cardiovascular Questions

A Chinese-led study analyzed 17 arterial samples from surgical procedures and detected microplastics in all of them, with higher levels in arteries containing fatty plaques (coronary and carotid) than in the aorta; PET was the dominant plastic. While the findings raise concerns about potential cardiovascular effects, the researchers caution that a direct causal link isn’t proven and call for further study, alongside other 2024 findings that microplastics may associate with arterial plaques and stroke risk.

Heat-exposed water: bottled drinks left in cars may leach chemicals and microplastics

Health experts warn that bottled water left in hot cars can allow chemicals like BPA and phthalates to leach from the plastic, along with microplastics migrating into the liquid and bacteria growing in the moisture and warmth; switching to stainless-steel or glass bottles and keeping bottles clean is advised to reduce exposure.

Activists push to include microplastics in drinking-water testing

The EPA's proposed drinking-water monitoring would require testing for up to 30 contaminants, but microplastics are not included, prompting a letter from 250 health professionals urging their addition; California has already moved ahead with microplastic screenings, though validated testing methods are not yet available, and the UCMR 6 timeline aims for finalization by year-end with implementation in 2028, while the public can submit comments by August 31.

Six practical swaps to cut microplastics from your meals

A Washington Post Well+Being piece explains how microplastics and related chemicals can enter everyday foods via plastic packaging and canned goods, and offers six practical swaps—such as avoiding plastic containers and cans, using glass or metal alternatives, and prioritizing fresh, minimally processed foods—to lower exposure and protect health.

Microplastics Detected in Blood of Most Severe Heart Attack Patients, Study Shows

A study of 61 patients undergoing coronary angiograms found micro- and nanoplastics in the blood of about 84% of those with active severe heart attacks, with polyethylene most commonly detected; researchers stress that this shows association, not causation, and smoking and air pollution complicate interpretation. The authors suggest reducing daily plastic exposure (e.g., using glass containers) as part of a broader heart-healthy lifestyle.

New Research Finds Microplastics in Blood of Most Acute Heart Attack Patients

Italian researchers analyzed blood from 61 patients undergoing angiograms and found micro- and nanoplastics in about 84% of those having an active, severe heart attack, far more than in those with chronic heart disease (40%) or normal arteries (32%). Polyethylene appeared in 97% of plastics-positive cases, and smoking was the strongest predictor of detectable plastic particles. The study, published in the European Heart Journal, shows an association rather than causation and is limited by size and scope; experts say reducing daily plastic exposure (e.g., using glass/ceramic containers and avoiding heating plastic) may be prudent as part of overall heart-healthy practices.

Microplastics Reach Deep-Sea Vents; Indian Ocean Species Harbor 14.7× More Particles

A KRIBB-KIOST study analyzed deep-sea snails and mussels from hydrothermal vents in the North Fiji Basin (Pacific) and Central Indian Ridge, finding microplastics in 92% of the animals (average 3.42 particles per specimen). Polystyrene was most common; grazing snails concentrated plastics in digestive organs, while mussels showed a more even distribution. After adjusting for body weight, Indian Ocean specimens had up to 14.7× higher microplastic concentrations than Pacific specimens, likely due to differences in human activity, river inputs, and circulation. The researchers emphasize that surface plastic pollution has reached remote deep-sea ecosystems and advocate for monitoring and conservation policies.

Deep-sea vents show microplastics infiltration, study finds

A KRIBB–KIOST study found microplastics contaminating over 90% of deep-sea molluscs living on hydrothermal vents deeper than 2,000 metres, with Indian Ocean samples nearly 15 times more polluted than those from the southwestern Pacific; most plastics were polystyrene, suggesting coastal pollution and riverine inputs are delivering microplastics even to Earth's deepest ecosystems and underscoring the need for deep-sea monitoring and conservation policies.

Plastic particles in coronary blood peak in heart attack patients, linked to smoking and pollution

A study of 61 patients found micro- and nanoplastics in coronary blood were most common in heart attack patients (84%), more varied than in those with chronic ischemic disease (40%) or normal arteries (32%). Smokers and those exposed to higher air pollution had higher rates of plastics in their blood, with polyethylene being the most common type. The authors stress that the findings show association, not causation, but suggest environmental plastic exposure could be linked to cardiovascular risk and highlight the need to reduce pollution and smoking exposure.

Microplastics in Carotid Plaques Linked to 4.5× Higher Risk of Heart Events

A 2024 NEJM study found microplastics and nanoplastics embedded in the carotid plaque of 58% of patients; those with plastic in their plaque were about 4.5 times more likely to have a heart attack, stroke, or death within 34 months than those with plastic-free plaque, with inflammation and plaque destabilization proposed as mechanisms. Causality isn’t proven and replication is underway in New Mexico and elsewhere to determine if microplastics are a modifiable cardiovascular risk factor.

Hard-to-die plastic: PET bottles linger for centuries and seed microplastics globally

A PET water bottle takes about 450 years to decompose; since the 1970s essentially every bottle produced remains somewhere on Earth, gradually fragmenting into microplastics that are now found from Arctic ice to deep Mariana Trench sediments, while global plastic production continues and most of it remains unrecycled, ensuring centuries of pollution as plastics persist and disperse through air, water, and soils.
