Microplastics: Environmental Presence and Ecological Impact

This review examines the widespread problem of microplastic pollution by exploring where it comes from, how it is distributed in the environment, its impact on ecosystems and human health, as well as recent advancements made in detecting and removing it. The discussion includes a focus on the distinct distributions of microplastics across marine, terrestrial, and freshwater systems, detailing their varying concentrations and the long-term implications for ecosystem functionality and biodiversity. It details how microplastics originate from consumer products and the breakdown of larger plastics that permeate marine, terrestrial, and urban environments and highlights how they enter food webs, thus endangering wildlife and humans. The review also considers the global regulations against microplastic pollution and the technological innovations used to reduce its presence. It also explores the socioeconomic impacts on industries reliant on marine resources and the innovative solutions for microplastic mitigation, including biodegradable plastics and circular economy approaches. The paper underscores the need for strong policy frameworks supported by international cooperation, calling for urgent action to address the ecological and health risks posed by microplastics. It emphasizes the critical role played by interdisciplinary research and innovative solutions in tackling this environmental threat.
