ClearEffects of PET microplastics on the physiology of Drosophila
Researchers used Drosophila fruit flies as a model to study the physiological effects of PET microplastics, finding that ingestion affected reproduction, lifespan, and gut function. The study suggests that even common plastic types found in food packaging can have measurable biological effects when consumed by living organisms.
Toxicological Profile of Polyethylene Terephthalate (PET) Microplastic in Ingested Drosophila melanogaster (Oregon R+) and Its Adverse Effect on Behavior and Development
Researchers fed PET microplastics to fruit flies and found that the particles accumulated in their bodies and caused dose-dependent declines in movement, climbing ability, and survival rates. Higher microplastic concentrations also slowed the flies' development from larvae to adults. While fruit flies are a simple model organism, these behavioral and developmental effects suggest that chronic microplastic ingestion could impair neurological and physiological functions in animals exposed through their diet.
The hazardous impact of true-to-life PET nanoplastics in Drosophila
Researchers created realistic nanoplastics by sanding commercial PET water bottles and tested their effects on fruit flies (Drosophila melanogaster). They found that these true-to-life nanoplastics were internalized through the digestive tract and distributed throughout the body, causing measurable biological impacts. The study highlights the importance of testing with environmentally relevant plastic particles rather than only laboratory-grade materials to accurately assess health risks.
Investigation of the effects of nanoplastic polyethylene terephthalate on environmental toxicology using model Drosophila melanogaster
Researchers synthesized polyethylene terephthalate nanoplastics and fed them to fruit flies to assess their toxic effects. The nanoplastics caused increased oxidative stress, reduced survival rates, and impaired reproductive capacity in the exposed flies. The study demonstrates that PET nanoplastics, one of the most common plastic types in food and beverage packaging, can have measurable toxic effects on living organisms.
Sustainable Management of Microplastic Pollutions from PET Bottles: Overview and Mitigation Strategies

Occurrence, analysis, and toxicity of polyethylene terephthalate microplastics: a review
This review focuses on polyethylene terephthalate (PET), one of the most common types of plastic found as microplastic contamination in food, beverages, dust, wildlife, and human tissues. The authors found major inconsistencies in how researchers measure and detect PET microplastics, making it difficult to accurately assess health risks. Better standardized methods are needed to understand the true scope of PET contamination.
A focused review on recycling and hydrolysis techniques of polyethylene terephthalate
This review examines techniques for recycling polyethylene terephthalate (PET), one of the most common plastics found as microplastic pollution. Chemical recycling through hydrolysis shows the most promise for breaking PET back into its original building blocks for reuse. Improving PET recycling is important because reducing plastic waste at the source is one of the most effective ways to decrease microplastic contamination in the environment.

Uptake and effects of polystyrene micro- and nanospheres on Drosophila melanogaster were studied, finding that both sizes of plastic particles affected locomotion and daily activity patterns. The results suggest that microplastic and nanoplastic ingestion can disrupt behavioral functions in the fruit fly model.
A review on microplastics: sources, environmental fate, degradation pathways, and analytical identification methods.
This review paper summarizes existing research on tiny plastic particles called microplastics and how scientists detect them in the environment. Microplastics are a growing concern because they contaminate our air, water, and food, potentially affecting human health when we breathe or eat them. The researchers found that new, cheaper detection methods could help us better monitor these plastic particles and understand their impact on our health and environment.
Polyethylene Terephthalate Hydrolases in Human Gut Microbiota and Their Implications for Human Health
Researchers searched the genomes of healthy human gut bacteria and discovered enzymes capable of breaking down PET, one of the most common plastics found in food and drink packaging. They identified multiple bacterial species in the human gut that produce these PET-degrading enzymes. This discovery suggests that gut microbes may play a role in processing the microplastics people swallow, though it also raises questions about whether the breakdown products could affect human health.

Polyethylene microplastics induce behavioural and developmental deficits in the Drosophila model
Researchers generated polyethylene microplastics sized 2-10 micrometers and tested their effects on fruit flies (Drosophila). They found that exposure caused severe declines in fly longevity, reduced locomotor function in both larvae and adults, decreased eclosion rates, and increased antioxidant enzyme activity along with stress-response gene activation. The findings provide evidence that polyethylene microplastics can impair growth, development, and survival in a well-established animal model.
PET microplastics affect human gut microbiota communities during simulated gastrointestinal digestion, first evidence of plausible polymer biodegradation during human digestion
Using a simulated human digestive system, researchers tracked what happens to PET microplastics as they pass through the stomach and intestines. The microplastics were structurally changed during digestion and appeared to alter the composition of gut bacteria, with some microbes forming biofilms on the plastic surfaces. This is the first evidence that microplastics may be partially broken down during human digestion and could disrupt the gut microbiome, which plays a critical role in overall health.
