Caribbean islands, including Puerto Rico, are biodiversity hotspots threatened by microplastics ( less then 5 mm).

Península La Esperanza, the most polluted beach, exhibited higher average abundance (17 items/kg dw) and diversity. High urbanization, industrial/port activities, and riverine input are likely sources of pla
