Do Microplastics have any significant effect on Red Blood Cells? An In-depth study by Systematic Review and Meta-Analysis
AI summary Read the abstract
This meta-analysis pools data from multiple studies to examine how microplastics affect red blood cells. The findings highlight a knowledge gap about how microplastics interact with our blood cells, which is significant because red blood cells carry oxygen throughout the body and any disruption could affect overall health.
Background: Despite growing interest, there remains a critical knowledge gap regarding the toxicodynamic interactions between MPs and human erythrocytes. This study was done to consolidate emerging evidence on microplastics’ effects on red blood cells and interpret their implications for public health. Methodology: In this study the studies were identified from multiple databases such as PubMed, Cochrane review, Google Scholar and all kind of data in any form of article was taken on 2 Key words “Microplastics” and “RBC” from last 20 years in Literature. Results: This systematic review of 63 articles provides consolidated evidence that MNPs interact directly with erythrocytes (RBCs), leading to oxidative damage, impaired deformability, and disruptions in oxygen transport. These effects are not isolated but form part of a broader cascade involving endothelial dysfunction, immune activation, and vascular complications. Most included studies report a statistically significant increase in haemolysis associated with the exposure under investigation, with effect sizes ranging from moderate (~6%) to large (~10%). Conclusion: Given the pervasive presence of microplastics in the environment, including recent confirmation of their presence in human blood, these findings raise significant concerns about their potential haematological and systemic health effects. Regulatory bodies and public health institutions must prioritize further investigation, public. Keywords: Microplastics, Red Blood Cells, Human Blood, Systematic Review, Meta-Analysis.

Are Polymeric Microparticles Dangerous for Red Blood Cells?
AI summary Read the abstract
This review of existing research shows that tiny plastic particles (microplastics) found in human blood can damage red blood cells by making them less flexible and even killing them. When red blood cells become damaged, they can't carry oxygen as well throughout the body, which could affect blood flow and overall health. While scientists need more research to understand the full health risks, this is concerning because microplastics are becoming more common in our environment and bodies.
The Impact of Micro/Nanoplastics on Human Hematopoietic Function: Exposure, Deposition, Toxicity, and Mitigation Strategies
AI summary Read the abstract
Researchers reviewed how micro- and nanoplastics enter the body via diet and inhalation and accumulate in blood cells and hematopoietic organs, synthesizing animal and in vitro evidence that these particles disrupt red and white blood cell production through oxidative stress and inflammatory signaling while also exploring biodegradation and dietary mitigation strategies.
Pengaruh Mikroplastik Polyethylene Terephthalate (PET) Terhadap Profil Eritrosit Tikus Betina Galur Wistar
AI summary Read the abstract
This animal study tested how PET microplastics (common in plastic bottles) affect blood cells in rats. Results showed that exposure to PET microplastics may lower red blood cell counts, hemoglobin, and hematocrit levels, suggesting potential effects on blood health that warrant further investigation in humans.
Microplastics in blood bags may affect red blood cells
AI summary Read the abstract
Scientists found tiny bits of plastic (microplastics) in bags used to store donated blood, likely coming from the plastic bags themselves, and these particles may affect the health of red blood cells over time. However, researchers caution it's too early to say blood bags need to be redesigned, more studies are needed to understand if this actually poses a risk to patients receiving blood transfusions.
Study of Microplastics in Human Blood
AI summary Read the abstract
This study reviewed findings on microplastic contamination in human blood, noting that particles have been detected in the majority of samples tested, while the health consequences remain unclear and warrant urgent further investigation.
