The impact of PET particles on zebrafish was examined by researchers. PET, the plastic commonly used to manufacture bottles, is a widespread presence in our ecosystem. Researchers from Leipzig University and the Helmholtz Centre for Environmental Research (UFZ) have recently collaborated on a study
Nanoplastics are tiny plastic particles measuring less than 100 nanometers in size. They are created from the breakdown of larger plastic debris, such as water bottles and plastic bags, and are prevalent in both marine and terrestrial environments. The small size of nanoplastics allows them to easily enter and interact with organisms, posing a potential threat to the ecosystem and food chain.PET, the plastic commonly used to manufacture bottles, is a widespread presence in our ecosystem.
Polyethylene terephthalate, known as PET, is a widely used plastic. It is used to make plastic bags as well as practical containers for food and drinks. Little is known so far about the damaging effects of PET nanoplastics. In a recently published research project, scientists at Leipzig University focused on the effects of PET nanoplastics on zebrafish embryos.
“Our study provides the very first insight into the toxicity pathways induced by PET nanoplastics and the underlying damaging mechanisms in intact zebrafish larvae. We found that liver function was significantly impaired and that there was oxidative stress. PET nanoplastics also affect the cellular membrane and energetics of living organisms,” said corresponding author Dr. Alia Matysik, a scientist at the Faculty of Medicine’s Institute of Medical Physics and Biophysics.
“This research finding highlights the adverse effects of PET nanoplastics, which have been observed in zebrafish embryos and may also play a role in mammals and humans. While we do not yet have a clear answer to this question, it is now safe to assume that PET nanoplastics are disrupting our ecosystems. In any case, plastics should be prevented from entering the environment.
