Abstract

Although inexpensive plastic items are helpful, they have greatly improved modern living. The increased micro-nanoplastics pollution has become a primary worldwide environmental concern, and aquaculture is becoming a research hotspot for investigation. They are small enough to be ingested by a wide range of organisms and may cross some biological barriers at a nano-scale. Micro-nanoplastics in aquatic habitats seriously threaten the entire food web. Micro-nanoplastics enter marine ecosystems through rivers, runoff, and atmospheric deposition, while radioactive contaminants come from industrial discharges and nuclear waste. Moreover, micro-nanoplastics can absorb hazardous contaminants i.e. radioactive isotopes and release harmful compounds, which degrade the aquaculture environment. Marine life can experience developmental delays and reproductive problems due to the micro-nanoplastics buildup in aquatic habitats and with radioactive contaminants exacerbating these effects. Thus, there needs to be more concern about aquaculture's ability to turn a profit. Promising techniques have also been observed for ecological purification and interception. To lessen the impacts of micro-nanoplastics contamination, several removal techniques, including filtering, coagulation, and sophisticated oxidation procedures, have been investigated. Additionally, improving aquaculture management practices, enhancing fishing gear, and utilizing better packaging materials are practical solutions currently being implemented. Developing portable monitoring systems for micro-nanoplastics and using remote sensing technology are anticipated to play significant roles in managing this pollution.
