B We have all heard how plastic pollution has overflowed every corner of the world. Recently, scientists have made a surprising discovery that microplastics are even found in the human bloodstream. After analyzing blood samples (样本) from 22 healthy people, researchers found microplastics in 17 of them! Most of the microplastics were classified as polyethylene terephthalate (PET), which is commonly found in drink bottles, and there were small amounts of polyethylene, which makes up plastic bags. Although the exact chemical effects of microplastics on our bodies are unknown, it is clear that the increasing amounts of plastic in our environment could bring a risk to human cells in the future. Microplastics were never considered a significant threat to the atmosphere until recent studies began to reveal that they could be found everywhere across the skies. For example, scientists recently discovered the presence of microplastics in the Pyrenees Mountain Range in Europe, believed to have arrived by rain or snow. The low mass of microplastics makes them spread through air, which is why they can travel hundreds, eve ... ...
