Microplastic bioaccumulation (MPB) within marine fish through the food chain has been extensively validated in traditional experimental studies. However, idealized conditions of these studies fail to fully capture complex, nonlinear interactions among microplastics, biota, and environmental factors real-world scenarios, spatiotemporal characteristics risks are lacking studies, hindering accurate assessment control risk. To address above knowledge gaps, we constructed an improved sparrow search algorithm/geographic random forest (ISSA-GRF) conceptual framework analyzed MPB 82 common species from coastal ecosystems. The rate 22 major ecosystems increased by average 3.56% over past decade. Hotspot areas such as Red Sea coast, Gulf Thailand Sulawesi coast were identified; rates 8.00%, 5.68%, 5.34%, respectively. Ocean eutrophication, triggered changes nutrient levels, was revealed main driver via a causal analysis. These findings not only independently validate increasing risk microplastic biological accumulation outside laboratory environment but also highlight importance controlling eutrophication mitigate associated with microplastics.
