A Model that Establishes a Parallel Behave Between Varying Chemicals and the Presence of Microplastics in the Ocean

Abstract

The box model is a commonly utilized tool for understanding oceanic phenomena, particularly regarding the spatial distribution of chemicals. In our study, we aimed to establish parallels between existing models that account for the input of various chemicals and the potential flux of microplastics within the ocean. Our objective was to bridge the gap between conventional chemical dynamics and the emerging concern of microplastic pollution. To achieve this, we examined the accumulation of microplastics within the ocean and their uptake by marine organisms while also considering processes such as mineralization and demineralization. Our model treated microplastics as constituents akin to traditional chemical elements like phosphorus (P) and oxygen (O), viewing the ocean as a dynamic system with inputs and losses. Through this modeling framework, we sought to identify our approach's strengths and weaknesses. One key observation was the realization that the ocean receives a significant influx of microplastics, surpassing its capacity for degradation or bioaccumulation. This recognition underscores the urgency of addressing microplastic pollution and highlights the need for effective management
strategies to mitigate its impact on marine ecosystems.
