Abstract
Microplastics have become a global environmental concern because of their widespread presence
in coastal areas, the open ocean, and polar regions. Microplastics in the environment originate
from a variety of land- and sea-based sources. Regional industrial and human activities may
affect the abundance and contamination characteristics of microplastics in their surrounding
environment, which may be reflected to marine species living in its water body and transfer
through their food web. This study investigated the contamination characteristics of
microplastics in abiotic matrices such as seawater and sediment, and biotic matrices such as
oyster, mussel, and lugworm in urban, aquafarm, and rural areas. In abiotic matrices, different
polymer composition of microplastic was found among three regions. High diversity was found
from urban area, implying diverse sources of microplastic in this area. Polystyrene was relatively
abundant in aquafarm area, reflecting well the wide use of expanded polystyrene buoys. In rural
area, polypropylene is relatively abundant, probably related with the wide use of polypropylene
rope in fishing activity. Microplastic compositions in marine invertebrates followed well those in
abiotic matrices. This result implies that the accumulation profile of microplastics by marine
invertebrates reflects regional human activities.egional industrial and human activities may
