ClearEfectos Celulares De La Exposición a Micropartículas Plásticas En Organismos Acuáticos
This review examines cellular effects of microplastic and nanoplastic exposure in aquatic organisms, synthesizing laboratory evidence that plastics alone or combined with other toxicants cause membrane lysis, mitochondrial damage, reactive oxygen species generation, genotoxicity, and apoptosis.
Toxicity in vitro reveals potential impacts of microplastics and nanoplastics on human health: A review
This review summarizes laboratory cell-culture studies examining the potential health impacts of microplastics and nanoplastics on human cells. Researchers found evidence that these particles can cause oxidative stress, inflammation, and disruption to normal cell functions across multiple cell types. The study suggests that while more research is needed, the in vitro evidence indicates microplastics and nanoplastics have the potential to affect human health through several biological pathways.
Cytotoxic Effects of Microplastics on Human Cells
This study reviewed and tested the cytotoxic effects of microplastics on human cells, finding that microplastic particles can cause cell damage, inflammation, and oxidative stress at relevant concentrations. The results support growing concern that microplastics ingested or inhaled by humans may pose direct health risks at the cellular level.
An assessment of the toxicity of polypropylene microplastics in human derived cells
Researchers assessed the toxicity of polypropylene microplastics on human-derived cell lines and found that the particles triggered inflammatory responses and oxidative stress at concentrations relevant to environmental exposure. The microplastics also affected cell viability and caused measurable changes in immune-related gene expression. The study raises concerns about potential health effects from chronic human exposure to one of the most commonly produced plastic types.
Evaluation of potential toxicity of polyethylene microplastics on human derived cell lines
Researchers tested the toxic effects of two sizes of polyethylene microplastics on human cell lines representing different tissue types. They found that microplastic exposure triggered inflammatory responses and caused cellular damage, with effects varying depending on particle size and cell type. The findings suggest that microplastics commonly encountered in everyday life could pose health risks when they interact with human tissues.
A rapid review and meta-regression analyses of the toxicological impacts of microplastic exposure in human cells
Researchers conducted a systematic review and statistical analysis of studies examining the effects of microplastic exposure on human cells in the laboratory. They found evidence that microplastics can cause cell damage, inflammation, and oxidative stress, with smaller particles and higher doses generally producing stronger effects. The study provides the first pooled estimate of dose-response thresholds for microplastic toxicity in human cells, helping to frame the potential health risks of daily exposure.
