Micro/nanoplastics (MNPs), plastic particles and fibers with sizes ranging from nanometers (≥ 1 nm) to micrometers (≤ 5 mm) have become emerging environmental pollutants and are widely distributed across various ecosystems worldwide. These tiny plastic particles not only pose a threat to marine ecosystems, but also present new challenges to terrestrial ecosystems. However, research on terrestrial MNPs lagged behind marine studies.
