Hemotoxic effects of polyethylene microplastics on mice

Researchers exposed mice to different concentrations of polyethylene microplastics for 15 days and studied the effects on their blood. The highest dose caused significant damage to red blood cells, leading to abnormal shapes and reduced blood cell counts, along with impaired liver and kidney function. The study suggests that microplastic exposure may have harmful effects on blood health in mammals, including patterns consistent with anemia.

Hematological consequences of polyethylene microplastics toxicity in male rats: Oxidative stress, genetic, and epigenetic links

Researchers gave male rats different doses of polyethylene microplastics orally for 35 days and found significant damage to blood cells and the blood-forming system. Higher doses caused oxidative stress, DNA damage, and changes in gene expression patterns related to blood cell production. The study suggests that chronic microplastic ingestion could harm the blood system through both genetic and epigenetic pathways.

Microplastics exposure altered hematological and lipid profiles as well as liver and kidney function parameters in albino rats (Rattus norvegicus)

Researchers fed albino rats different concentrations of microplastics for 28 days and measured changes in blood, liver, kidney, and lipid profiles. They found dose-dependent effects including reduced immune cell counts suggesting immunosuppression, lower red blood cell levels indicating anemia, and altered liver and kidney function markers. The study provides evidence that microplastic ingestion may affect multiple organ systems and blood health in a way that worsens with higher exposure levels.

Microplastic contamination of donated blood and red cell concentrates

Researchers investigated whether blood donation and processing procedures introduce microplastics into transfusion products, finding that plastic blood collection packs and processing steps may contribute to microplastic contamination. Microplastics have previously been found in human blood at varying concentrations, with potential associations to vascular and thrombotic effects. The study raises important questions about whether blood processing equipment may be an underrecognized source of microplastic exposure for transfusion recipients.

PET-microplastics trigger endothelial glycocalyx loss via ER stress and ROS unleashing IL-1β-driven SMC switching and early aortic structural impairment

Scientists found that tiny plastic particles from bottles and food packaging can damage blood vessels when consumed regularly. In lab rats, these microplastics caused harmful changes to the cells lining arteries, which could lead to heart disease over time. This research suggests that plastic pollution may pose a direct threat to our cardiovascular health, though more studies are needed to confirm the effects in humans.

Potential risk of aromatic microplastic fragments during urinary excretion

Researchers compared aromatic PET and alkyl polypropylene microplastics in human blood, finding that PET adsorbed roughly three times more proteins and red blood cells, then preferentially stuck to vascular and urinary epithelial cells, triggering oxidative stress and cell death markers — suggesting that brief transit through the body is not biologically harmless.

Improved multivariate quantification of plastic particles in human blood using non-targeted pyrolysis GC-MS

Scientists developed improved methods for measuring plastic particles in human blood, finding that standard techniques can produce significant errors, especially for PET plastic. The new multivariate approach reduced measurement errors by up to 38%, which is important because accurate blood measurements are essential for understanding how much microplastic exposure people actually face.

Acute Toxicity Assessment of Orally Administered Microplastic Particles in Adult Male Wistar Rats

Researchers gave adult male rats a single oral dose of microplastics made from PET water bottles and found that even this one-time exposure altered markers of liver, heart, and kidney function. Higher doses also reduced food intake and increased signs of oxidative stress, which is cell damage caused by harmful molecules. This study suggests that even brief microplastic exposure could trigger early changes in organ function, raising questions about the cumulative effect of daily human exposure through food and water.

Multispectroscopic Investigations of the Binding Interaction between Polyethylene Microplastics and Human Hemoglobin

Scientists used multiple spectroscopic techniques to investigate whether polyethylene microplastics can bind to human hemoglobin, the protein that carries oxygen in blood. They found that microplastic particles do interact with hemoglobin, altering its structural shape and potentially affecting its function. The findings raise questions about what might happen when microplastics enter the human bloodstream and interact with essential blood proteins.

Renal and Hepatotoxic Effects of Polyethylene Terephthalate Microplastics in Chronically Exposed Albino Rats

Researchers exposed albino rats to different doses of PET microplastics for 90 days and measured kidney and liver function markers. They found that chronic exposure led to significant changes in serum urea, creatinine, and liver enzymes, suggesting potential kidney and liver damage at higher doses. The study also found that water stored in PET containers exposed to sunlight showed similar toxic effects, raising concerns about everyday plastic container use.

Evaluating Cellular Effects of PET Microplastics in 2D/3D Models: Methodological Considerations of Reagent Interference

Researchers assessed the cellular effects of PET microplastics using both 2D and 3D cell culture models and found dose- and cell-type-dependent reductions in viability along with rapid generation of reactive oxygen species. The study highlights significant methodological challenges, as microplastics can interfere with common lab assays through light scattering, dye adsorption, and surface interactions, potentially producing misleading results without appropriate controls.

Microplastic particles in human blood and their association with coagulation markers

In a study of 36 healthy adults, microplastics were detected in the blood of 89% of participants, with polypropylene and polyethylene being the most common types found. Higher microplastic levels were associated with changes in blood clotting markers, suggesting that plastic particles in our bloodstream may affect how our blood coagulates, though larger studies are needed to confirm this link.
