Microplastics in aquaculture environments: Current occurrence, adverse effects, ecological risk, and nature-based...

Area of Science:

• Environmental Science
• Aquatic Toxicology
• Food Safety

Background:

• Microplastics originate from diverse sources, including land-based waste, shipping, and atmospheric deposition.
• In aquaculture, microplastics release additives, attract pollutants, degrade habitats, and cause toxicological effects.
• Assessing microplastic fate in aquaculture is vital for understanding watershed contamination and ecological impacts.

Purpose of the Study:

• To analyze the repercussions of microplastic contamination in aquaculture.
• To highlight ecological consequences for aquaculture species and human health threats.
• To propose nature-based solutions for microplastic removal.

Main Methods:

• Comprehensive literature review on microplastic sources, impacts, and mitigation strategies in aquaculture.
• Analysis of ecological risks and toxicological effects on aquaculture species.
• Evaluation of proposed nature-based solutions, including biofilters, biodegradation, and wetlands.

Main Results:

• Microplastics pose significant ecological and human health risks within aquaculture systems.
• Aquaculture can contribute to microplastic contamination within watersheds.
• Nature-based solutions show promise for microplastic removal in aquatic ecosystems.

Conclusions:

• Strict regulations are essential to control microplastic presence in aquaculture and ensure food safety.
• Novel approaches like microplastic biofilters and biodegradation offer effective removal strategies.
• Further research and emergency treatment measures are needed to address microplastic impacts on aquaculture and human health.
