Abstract:
Microplastics (MPs) are pervasive in various environmental media, posing a significant global issue. However, long-term data on marine MPs pollution trends are limited. This study investigates sediment samples from six stations in Sishili Bay, Yellow Sea, collected in 2015, 2018, and 2021, an area impacted by industrial, maricultural, and tourism activities. Findings reveal an annual increase in MPs abundance, with mean concentrations of 92.60 ± 23.93 items/kg.dw in 2015, 146.18 ± 14.80 items/kg.dw in 2018, and 203.21 ± 20.31 items/kg.dw in 2021. MPs distribution is spatially uniform, showing no significant seasonal changes, attributed to the bay's semi-enclosed nature. Predominant MPs are fibers (>70 %) and transparent particles (>35 %), with most particles <1000 μm. PET and Rayon are the main polymers identified. The study emphasizes the escalating MPs pollution in the mariculture area, highlighting the urgent need for targeted pollution control and mitigation strategies.
