Microplastics are some of the Earth’s tiniest and 【小题1】 (harm) enemies. 【小题2】new study reveals that microplastics have even polluted Alpine snow and Arctic ice. How did the microplastics get there? The study,【小题3】 (publish) this week in the journal Science Advances,assumes that the tiny particles become airborne and, when 【小题4】 (sweep) up into the Earth’s atmosphere, can be transported virtually around the globe. If microplastics 【小题5】(find) in original Arctic ice, they’re probably being breathed in, lived in and eaten by animals in other ecosystems.【小题6】 microplastics are being swirled around the atmosphere, the study says, we’re breathing 【小题7】in, as well. And that could have serious health 【小题8】 (consequent).“The high MP concentrations detected in snow samples from continental Europe to the Arctic indicate significant air pollution and stress the urgent need for research 【小题9】 human and animal health effects 【小题10】 (focus) on airborne MPs,” the study says.
