ClearRole of recirculating aquaculture systems (RAS) in the generation and removal of microplastics and additives chemicals
Researchers investigated the generation and presence of microplastics and additive chemicals within recirculating aquaculture system (RAS) infrastructure by building a reference library of plastic sources and conducting targeted analysis of intake water, recirculating water, sludge, fish, and fish feed. Results identified plastic infrastructure and consumables as potential microplastic sources, though detected levels above 300 µm were low.
Occurrence, distribution and sources of microplastics in typical marine recirculating aquaculture system (RAS) in China: The critical role of RAS operating time and microfilter
This study found microplastics in all parts of fish farming systems in China, including the feed, water, and the fish themselves. Systems that had been running longer accumulated more microplastics, and the plastic types found in fish closely matched those in their feed and water. The findings suggest that farmed fish -- a major protein source -- can be a route of microplastic exposure for people who eat seafood.

Microplastics in aquatic environments: a review of recent advances
This review synthesizes recent advances in understanding microplastic contamination in aquatic environments, covering sources, distribution, and physical, chemical, and biological removal methods, and highlighting that no standardized cost-effective removal solution currently exists. The review emphasizes that microplastics cycle through natural and engineered systems, requiring whole-system approaches to avoid unintended recontamination.
Microplastics in aquatic systems, a comprehensive review: origination, accumulation, impact, and removal technologies
This comprehensive review traced the sources of microplastics in aquatic environments, from industrial products and packaging to cosmetics and agricultural materials, and examined their toxic effects on living organisms. Researchers found that microplastics are remarkably stable and widespread, posing growing ecotoxicological risks to aquatic ecosystems. The study also evaluated current removal technologies, noting their advantages and limitations, and warns that without better strategies, microplastic pollution will become significantly worse in coming decades.

A review of microplastic pollution in aquaculture: Sources, effects, removal strategies and prospects
This review examines how microplastics contaminate fish farms through environmental inputs and aquaculture equipment, affecting water quality and the health of farmed seafood. Since contaminated aquaculture products are a direct pathway for microplastics to reach the human diet, reducing plastic pollution in fish farming is important for food safety.

When it Comes to Microplastic Pollution, is the Aquaculture Industry a Victim or Perpetrator?
This systematic review examines microplastic contamination in aquaculture facilities and the animals raised in them. The findings show widespread microplastic presence in farmed fish and shellfish, meaning that aquaculture products are a significant pathway for human microplastic exposure, which could affect immune function over time.
Aquatic toxicity of chemically defined microplastics can be explained by functional additives
Researchers manufactured microplastics from four polymer types with precisely defined chemical compositions, including different additive formulations, and tested their toxicity to aquatic organisms. They found that the toxic effects of microplastics could largely be explained by the functional additives they contained rather than the base polymer itself. The study suggests that the chemical additives in plastics, not just the plastic material, are a primary driver of microplastic toxicity in aquatic environments.
Plastic additives and microplastics as emerging contaminants: Mechanisms and analytical assessment
Researchers reviewed how chemical additives mixed into plastics during manufacturing — including stabilizers, flame retardants, and plasticizers — can leach out throughout a plastic's lifecycle and pose risks to ecosystems and human health, with microplastics acting as carriers that concentrate and transport these hazardous chemicals.

This review covers methods for detecting and removing microplastics from wastewater, which is a major pathway for microplastics to enter the environment.
