Micro Plastics in Marine Ecosystem

Abstract

Microplastics have emerged as a significant environmental concern, affecting marine ecosystems from primary producers like phytoplankton to apex predators such as marine mammals. These microscopic plastic particles originate from the breakdown of larger plastic materials, synthetic fiber wear, and cosmetic products, contributing to widespread oceanic contamination. Since 1950, global plastic production has exceeded 10 billion tons, with increasing annual output exacerbating pollution levels. Microplastics pose ecotoxicological risks, potentially impacting aquatic biodiversity and human health through bioaccumulation in the food chain. Research funded by the Joint Programming Initiative Healthy and Productive Seas and Oceans (JPI Oceans) explores their distribution in tropical and temperate waters, providing crucial insights for informed policymaking. This study examines the occurrence, types, and effects of microplastics in marine environments, highlighting their role in ecosystem disruption. To mitigate plastic pollution, efforts must focus on recycling, repurposing, and fostering innovative alternatives to single-use plastics, ensuring long-term sustainability for marine ecosystems.
