Скачать или смотреть Are You Eating a Credit Card a Week? The Truth About Microplastics

Did you know that in 2023 alone, the world produced over 400.3 million metric tons of plastic?. But the real problem isn't just the visible trash; it's what you can't see.

In this episode of Fernandes Science, we dissect the "Invisible Invasion" of Microplastics and Nanoplastics. We are looking at the physics of fragmentation and the biology of exposure to understand how these particles—smaller than 5mm—are bypassing our biological barriers.

What the science says (No Filters): 💳 The Plastic Diet: Research estimates we could be consuming up to 5g of plastic per week—roughly the weight of a credit card. 🫁 Routes of Exposure: From ingestion (water/food) to inhalation and dermal contact. 🧬 Cellular Impact: We analyze in vitro studies showing potential cytotoxicity (cell death), inflammation, and even genotoxicity (DNA damage).

We dive into the latest papers to separate the panic from the data. The science is still evolving, but the signals are there.

Welcome to Fernandes Science. ⚛️🧬🐕 I’m David Fernandes, a Veterinary Medicine student. I believe that to understand life (Biology), we must understand the rules of the universe (Physics). Here, we dissect science based on the most recent and highly cited papers.
