“…Previous studies showed that marine litter and microplastic can be found in all segments of the Adriatic marine environment, such as biota vertebrates [2,37,39] and invertebrates [36], exposing them to threats related to marine litter such as ingestion and entanglement. Furthermore, marine litter and microplastic are present in the water column [3], sediments [35,37], sea bottom [20,38], and beaches [1,24,33,34], as well as in kitchen salt for human consumption [45]. Levels of heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) [15] were found in the collected plastic pellets from two sandy beaches on the island of Vis, and microplastic was characterized from samples from the sandy sediment of Prapratna beach [46].…”
