Abstract Microplastics (MPs) resulting from plastic fragmentation with a size less than 5 mm have become one of the main pollutants endangering water environment. Therefore, it is necessary to know about abundance and distribution in sewage waters as well influences quality on MPs. In this study, samples are collected 20 outlets Guilin, China, analyze morphology MPs their hydrochemical characteristics. Multivariate statistical analyses conducted identify major factors related MPs’ waters. Results show that mainly composed fiber film, 67.8% <0.3 mm. The range 6 (±1)–47 (±3) items/L. correlation analysis presents weakly correlated parameters metal ions due complexity data. redundancy indicates significantly affected by NO3-N, Zn, Ca, Cu contents, contents. study highlights occurrence characteristics environmental influencing water, which may be significant for future studies pollution control

Microplastics (MPs) resulting from plastic fragmentation with a size less than 5 mm have become one of the main pollutants endangering water environment. Therefore, it is necessary to know about abundance and distribution MPs in sewage waters their relationship quality. In this study, samples are collected 20 outlets Guilin, China analyze morphology hydrochemical characteristics. Multivariate statistical analyses conducted identify major factors related MP samples. Results showed that mainly composed fiber film, 67.8% sized <0.3 mm. The range 6 (±1)–47 (±3) items/L. correlation analysis presents weakly correlated parameters metal ions due complexity data. redundancy indicates significantly affected by NO3–N, Zn, Ca, Cu contents, contents. Adsorption kinetics analyzed using pseudo-first-order, pseudo-second-order, intraparticle diffusion models, revealing adsorption process predominantly governed chemisorption for smaller (0.3–0.5 mm), while larger (1.0–5.0 mm) constrained internal diffusion. Isothermal experiments fitted Langmuir Freundlich indicating nutrients (NH3–N, TN, TP) (Ca, Mg, Cu, Pb, Zn) on follows monolayer mechanism, showing higher capacities specific surface areas. This study highlights occurrence characteristics environmental influencing water, which may be significant future studies pollution control MPs.

Seagrass beds are significant sinks for microplastics. However, the degradation of seagrass poses challenges, and evidence regarding its impacts on microplastic remains scarce. In this study, sediment cores were collected to investigate stock composition, carbon, organic carbon in Zostera japonica bed adjacent degraded area a lagoon Swan Lake, China. The (84.5 ± 18.5 million particles ha -1 ) was found significantly higher than (51.8 0.6 ), resulting release 38.7% buried microplastics reactivated water column. Similarly, 30.0% 66.1% total eroded due degradation. stocks derived from estimated at 0.19 0.10 kg C 0.13 0.11 area, contributing minimally (0.0023% 0.0026%, respectively). Notably, within single year may trigger rapid erosion over 20 years Lake. A linear relationship observed between contents (Organic = 1990 + 35100 × Microplastic R² 0.26, p &lt; 0.001). Microplastics sediments predominantly fiber (48.1%), black (40.7%), 250–500 µm (47.0%) while plate (26.7%), blue transparent, each 26.7% 125–250 (38.2%) bed. not only reduce but also alter their composition. This study initially quantified contribution underscored urgent need conservation mitigate climate change prevent remobilization historically
