ClearVariations in microplastic pollution characteristics among different aquaculture modes: A case study from Dongting Lake area, China
A study of four aquaculture modes in China's Dongting Lake region found microplastics in all water and aquatic organism samples, with swamp eel ponds having the highest contamination and advanced ecological/facility systems showing notably lower levels. The findings are important for food safety because edible aquatic species across all farming methods were exposed to microplastics, with tailwater continuing to export contamination even from cleaner facilities.
A Review of the Distribution of Antibiotics in Water in Different Regions of China and Current Antibiotic Degradation Pathways
This review summarized the spatial and temporal distribution of antibiotic contamination across major Chinese water bodies, identifying livestock farming, pharmaceutical manufacturing, and aquaculture as primary sources and reviewing current biological and physicochemical degradation pathways.
Occurrence and Characteristics of Microplastics Contamination in Different Intensive Aquaculture Systems Nearby the Yangtze Estuary, China
Researchers compared microplastic contamination across four types of aquaculture systems near China's Yangtze Estuary, finding that earthen ponds had the highest concentrations (13.81 particles/L) while recirculating aquaculture systems had the lowest, with fibers being the dominant shape in most settings.
Aqua Drugs, Antibiotics and Chemicals Used in Freshwater Aquaculture in Northern Bangladesh: A Survey
A survey of freshwater aquaculture operations in northern Bangladesh documented widespread use of antibiotics and other chemicals for disease management, raising concerns about antibiotic resistance and environmental contamination. The findings highlight a lack of regulation and oversight of drug use in small-scale aquaculture that could accelerate antimicrobial resistance.
Occurrence of microplastic in the water of different types of aquaculture ponds in an important lakeside freshwater aquaculture area of China
Microplastics were detected in aquaculture pond water across an important freshwater aquaculture region in China, with pond type and cultured species influencing microplastic occurrence and composition.
Microplastic contamination caused by different rearing modes of Asian swamp eel ( Monopterus albus )
This study compared microplastic contamination in eels raised in four different aquaculture systems and found that recycled-water systems had the highest microplastic levels in eel tissues and wastewater. The farming method significantly affects how much microplastic contamination accumulates in farmed seafood, with implications for food safety standards in eel production.
Evaluating Pollution from Aquaculture Materials and Developing Sustainable Alternatives to Reduce Marine Environmental Impacts: A Case Study in Vietnam
Researchers assessed the status of marine pollution associated with aquaculture activities in Vietnam, with particular emphasis on plastic and microplastic contamination from aquaculture materials, and developed recommendations for more sustainable alternatives to reduce the environmental footprint of coastal aquaculture operations.
Prevalence and transmission risk of colistin and multidrug resistance in long-distance coastal aquaculture
Researchers investigated antibiotic-resistant bacteria and colistin resistance genes in long-distance coastal aquaculture farms. They found widespread multidrug-resistant bacteria and evidence that resistance genes can transfer between different bacterial communities through horizontal gene transfer. The findings highlight aquaculture farms as significant reservoirs for antimicrobial resistance that could spread through the broader environment.
A review on source, occurrence, and impacts of microplastics in freshwater aquaculture systems in China
This review examines microplastic pollution sources, occurrence, and impacts within freshwater aquaculture systems in China, the world's leading aquaculture producer. Researchers found that microplastics are widespread in Chinese aquaculture environments, originating from feeds, equipment, and surrounding water sources. The study highlights concerns about food safety and product quality, suggesting that microplastic contamination in farmed fish and shellfish deserves greater regulatory attention.
The problem of contamination of aquatic ecosystems with antibiotics (a review)
This review examines the contamination of aquatic ecosystems by antibiotics, synthesizing global data on risks associated with antibiotic presence in ocean and freshwater environments, including effects on aquatic organisms and the promotion of antibiotic resistance. The authors assess quantitative and qualitative contamination using bivalves as bioindicators and evaluate the spread of resistance genes through aquatic biocenoses.
The Occurrence, Distribution, Environmental Effects, and Interactions of Microplastics and Antibiotics in the Aquatic Environment of China
This review characterizes the co-occurrence of microplastics and antibiotics in Chinese aquatic environments, summarizing their sources, spatial distributions, and the environmental effects of their interactions.
A Review on the Main Antibiotic Drugs Used in Fish Farming: Ecotoxicity, Characterization and Remediation
This review examines antibiotics used in fish farming and their ecotoxicological effects on aquatic ecosystems, noting that pharmaceutical residues accumulate in water and sediments and promote antibiotic-resistant bacteria. Understanding drug fate and effects in aquaculture environments is important for protecting both ecosystem health and the safety of farmed seafood.
Characteristics of microplastic pollution and analysis of colonized-microbiota in a freshwater aquaculture system.
Researchers found microplastics averaging 288.53 items per liter in freshwater aquaculture ponds in China, dominated by transparent fibers and cellulose particles, and discovered that bacterial communities on microplastic surfaces had significantly higher species richness and diversity than those in surrounding water. The plastisphere communities were enriched with Proteobacteria, including cellulose-degrading and potentially pathogenic species.
Occurrence, fate, and risk assessment of antibiotics in typical pharmaceutical manufactories and receiving water bodies from different regions
Researchers surveyed four pharmaceutical manufacturing facilities in China and found thirteen different antibiotics in their wastewater and nearby receiving water bodies at concentrations up to 727 nanograms per liter. Fluoroquinolones and macrolides were the most prevalent classes, and while wastewater treatment removed some antibiotics, significant residues persisted in the environment. The study highlights pharmaceutical manufacturing as an important source of antibiotic pollution in waterways.
The impact of microplastics on antibiotic resistance genes, metal resistance genes, and bacterial community in aquaculture environment
Researchers discovered that microplastics in fish farming environments carry significantly higher levels of antibiotic resistance genes and disease-causing bacteria like Brucella and Pseudomonas compared to surrounding water. This means microplastics may act as floating platforms that help spread antibiotic-resistant infections through aquaculture, potentially reaching humans who consume the seafood.
Combined pollution of antibiotics and microplastics in livestock breeding process: Occurrence and correlation
Researchers conducted an integrated assessment of antibiotic and microplastic co-occurrence across four environmental matrices (feed, manure, soil, and sewage) from livestock farms in South China. Antibiotics were widely detected at highest concentrations in manure and sewage, and the study found correlations between antibiotic use and microplastic co-contamination in the farming ecosystem, highlighting compounding pollution risks from intensive livestock operations.
