The contamination of microplastics and antibiotics in aquaculture wastewater: Their remediation technologies and interaction effects on their removal.

Water Quality
If you grow food with irrigation water sourced near fish farms or downstream waterways, both antibiotic residues and microplastic particles can reach your soil — and once antibiotics bind to plastic fragments, standard water-treatment filters may miss them entirely.
Fish farms produce wastewater laced with tiny plastic bits and leftover antibiotics from fish treatment. Scientists discovered these two types of pollution don't just sit side by side — plastic fragments can grab onto antibiotic molecules and carry them places, while antibiotics can interfere with how plastics break down. Current cleanup methods weren't designed with this interaction in mind, so they often fall short.
Key Findings
Microplastics adsorb antibiotic molecules onto their surfaces, altering how far antibiotics travel and how easily they are captured during water treatment.
Antibiotics can compete with microplastics for reactive oxygen species and adsorption sites, reducing the effectiveness of treatments targeting either pollutant alone.
The co-presence of microplastics and antibiotics can change antibiotic hydrolysis rates and biotoxicity, influencing biodegradation — yet how the same interactions affect microplastic behavior remains largely unstudied.
chevron_right Technical Summary
Aquaculture wastewater carries both tiny plastic fragments and antibiotic drugs into waterways, and the two pollutants interact in ways that make each harder to remove. This review maps current cleanup technologies and calls for combined approaches that account for how microplastics and antibiotics affect each other during treatment.
