Green roofs shown to capture nearly all microplastics from rainwater

A small team of researchers at Tongji University, working with a colleague from the Shanghai Academy of Landscape Architecture Science and Planning, both in China, has found that growing plants on roofs can serve as an effective way to remove microplastics from the air. In their study, published in the journal Communications Earth & Environment, the group measured the amounts of microplastics found on plants and the soil in which they grow.
