Correction: Jia et al. Exposure to Polypropylene Microplastics via Oral Ingestion Induces Colonic Apoptosis and Intestinal Barrier Damage through Oxidative Stress and Inflammation in Mice. Toxics 2023, 11, 127
AI summary Read the abstract
This is a published correction to an earlier study on exposure to polypropylene microplastics via oral ingestion in mice, which found that polypropylene induced colonic apoptosis and intestinal barrier damage through oxidative stress and inflammation. The correction addresses specific errors in the original publication without changing the main findings.

Exposure to Polypropylene Microplastics via Oral Ingestion Induces Colonic Apoptosis and Intestinal Barrier Damage through Oxidative Stress and Inflammation in Mice
AI summary Read the abstract
Researchers gave mice polypropylene microplastics (smaller than 10 micrometers) by mouth for 28 days and found significant damage to the colon, including inflammation, destruction of the gut barrier, and increased cell death. The smaller particles caused more severe damage than larger ones, triggering an inflammatory pathway that broke down the protective lining of the intestine. This is one of the first studies on polypropylene, the most common plastic found in human tissue, showing it can damage the gut at sizes small enough to be absorbed by the body.
Correction to: No prominent toxicity of polyethylene microplastics observed in neonatal mice following intratracheal instillation to dams during gestational and neonatal period
AI summary Read the abstract
This is a published correction to an earlier study that found no significant toxicity from polyethylene microplastics in newborn mice exposed through their mothers. The correction addresses a methodological detail in the original paper. The underlying finding — that intratracheal exposure to polyethylene microplastics during pregnancy and nursing caused no prominent toxicity — remains unchanged.
Correction: Novel probiotics adsorbing and excreting microplastics in vivo show potential gut health benefits
AI summary Read the abstract
A correction notice for an earlier mouse and lab study of two probiotic strains and polystyrene particles. The notice itself reports no methods or results.
Correction: Comprehensive investigation on microplastics from source to sink
AI summary Read the abstract
This correction clarifies that a prior review paper mischaracterized evidence on microplastic gut translocation, replacing the incorrect statement that most spherical microplastics pass through the gut wall with the accurate interpretation of the cited source.
Correction to Human Consumption of Microplastics
AI summary Read the abstract
This paper is a published correction to the 2019 study "Human Consumption of Microplastics" by Cox et al., which estimated how many microplastic particles people ingest annually through food, water, and air. The correction updates specific data or calculations in that widely cited paper.
