Abstract
Riverine input is an important pathway for transporting microplastic to the ocean. Nevertheless, the information of microplastic in freshwater system is poorly understood. A heavily urbanized semi-enclosed bay, Masan Bay, in Korea was investigated spatiotemporally. The mean concentration of microplastics in five creeks was 1681 ± 480 (700-3360) n/m3. The high abundance of microplastics was detected in creeks crossing the high populated and industrialized areas than less populated and agricultural areas. The concentration of microplastic was high during the periods of high precipitation (July and September). The major polymer type was polypropylene (PP) and polyethylene (PE). Fragment was dominant shape, and less than 300 μm size range accounted for 70% of the total microplastics. The annual flux of microplastics into the bay via creek waters was estimated as 2.8×1011 n/y. Input of microplastics was increased in September after rainy season.
