Summary

This study investigated microplastic transport and redistribution in deep-sea sediment systems, examining how particle characteristics and ocean current dynamics influence deposition patterns. The findings reveal that deep-sea environments accumulate microplastics from distant surface sources, with long-term implications for benthic ecosystem health.
