AI Article Synopsis
- Microplastics (MPs) are a growing environmental issue, particularly in areas like Sishili Bay, where their prevalence has significantly increased over recent years.
- * The study analyzed sediment samples from 2015, 2018, and 2021, revealing a rise in MPs abundance from 92.60 items/kg.dw in 2015 to 203.21 items/kg.dw in 2021.
- * Most MPs found were fibers and transparent particles, primarily made up of PET and Rayon, with an urgent call for targeted pollution control measures in mariculture zones.*
Article 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.
