Marine microfiber pollution: A review on present status and future challenges

Area of Science:

• Environmental Science
• Marine Biology
• Ecotoxicology

Background:

• Microfibers are a significant and growing environmental pollutant.
• Millions of tonnes of microfibers enter marine ecosystems annually, primarily from synthetic textiles and laundry.
• These pollutants are widespread, impacting aquatic environments globally.

Purpose of the Study:

• To review global microfiber generation and sources.
• To examine pathways of microfiber entry into the environment and food chain.
• To assess the threats posed by microfibers to aquatic life and humans, and to explore current and future treatment technologies.

Main Methods:

• Literature review of microfiber generation, environmental pathways, and ecological impacts.
• Analysis of current microfiber treatment technologies.
• Discussion of challenges in microfiber pollution control.

Main Results:

• Domestic laundry is a major source of microfiber pollution, releasing substantial amounts per garment.
• Rivers contribute significantly to the influx of synthetic fabric waste into the oceans.
• Oceans already contain an estimated 1.5 million trillion microfibers, posing a direct threat through ingestion by marine animals.

Conclusions:

• Microfiber pollution presents a critical environmental challenge with widespread ecological consequences.
• Effective treatment techniques are crucial for mitigating microfiber contamination.
• Further research and technological advancements are needed to address future challenges in microfiber pollution control.
