Intestinal effects of ingested PVC microplastic in Wistar rats
Summary
Researchers fed Wistar rats PVC microplastics and assessed intestinal effects including permeability, colonic morphology, and inflammatory markers. The findings showed that ingested PVC microplastics caused measurable changes in gut integrity and inflammation, contributing evidence for gastrointestinal toxicity.
Plastic has become a global environmental threat due to its irresponsible use and inadequate waste management, which has eventually led to the accumulation of microplastic in terrestrial and aquatic environments. Microplastics are now a growing concern for their impact on the ecosystem as well as human health. Humans are exposed to microplastic daily, mainly through ingestion and inhalation. With the ingestion of contaminated food and drinks or release of microplastic from food contact materials believed to be the main exposure route. This study aims to investigate the effects of ingested polyvinyl chloride (PVC) microplastic on animals’ overall wellbeing, intestinal permeability and colonic gene expression in Wistar rats.

Exposure to High-molecular-weight Polyvinyl Chloride Alters Bacterial Diversity in the Gut Microbiota of the Wistar Rat
Researchers exposed Wistar rats to high-molecular-weight polyvinyl chloride microplastics through their diet and measured changes in gut microbiota diversity and composition. PVC microplastic ingestion significantly altered bacterial diversity in the gut microbiome, supporting the hypothesis that microplastic exposure can disrupt intestinal microbial ecology with potential consequences for host health.
The Histopathological and Genetic Effects of Long-Term Treatment with High-Molecular-Weight Polyvinyl Chloride on Various Organs of Young Wistar Rats
Researchers fed young Wistar rats food containing 1% or 2% polyvinyl chloride for eight weeks, finding histopathological damage to the intestines, liver, kidney, and spleen, along with genetic effects including DNA fragmentation, demonstrating organ-level toxicity of chronic PVC microplastic ingestion.
Intestinal permeability and gene expression after polyethylene and polyamide microplastic ingestion in Wistar rats
Researchers found that Wistar rats fed polyethylene and polyamide microplastics for five weeks showed changes in intestinal gene expression related to mucin production and immune response, though intestinal permeability was not significantly altered.
Polyvinyl chloride microplastics induced gut barrier dysfunction, microbiota dysbiosis and metabolism disorder in adult mice
Researchers exposed adult mice to PVC microplastics for 60 days and observed significant damage to the intestinal barrier, including reduced mucus production and increased gut permeability. The exposure also caused notable shifts in gut bacteria composition and altered metabolic profiles in ways associated with intestinal injury. These findings suggest that chronic microplastic ingestion may disrupt gut health by weakening the intestinal lining and changing the microbiome.
Effects of Microplastic on the Gastrointestinal Tract and Gut microbiome of Sprague Dawley Rats
Adult male rats were fed polyethylene microplastics mixed with standard food for 24 days to assess effects on gastrointestinal tissue histology and gut microbiome composition. Microplastic exposure caused histological changes in the gastrointestinal tract lining and altered gut microbial diversity, providing direct evidence that oral microplastic ingestion disrupts gut health in mammals.
