摘要: We investigated the physical properties of beaches contaminated with plastic fragments. We compared sediment cores from Hawai 'i Island's Kamilo Beach, notable for plastic accumulation, to cores from a nearby beach. Compared to the nearby beach, Kamilo sediments contained more plastics (up to 30.2% by weight), were coarser-grained, and were more permeable (t-test, p< 0.0001). 85% of the fragments were polyethylene, and 95% were concentrated in the top 15cm of the cores. We constructed artificial cores of standardized …
