Accumulation of antibiotics in the environment: Have appropriate measures been taken to protect Canadian human and ecological health?
This review examines how antibiotics and other contaminants of emerging concern, including microplastics, are legally discharged into Canadian freshwater from treatment plants and accumulate in the environment. The buildup of these substances raises concerns about antibiotic resistance and ecosystem disruption, with potential downstream effects on human health through contaminated drinking water and food sources.
Pharmaceuticals in Water: Risks to Aquatic Life and Remediation Strategies
This review examines how pharmaceutical drugs in waterways threaten aquatic life and potentially human health. The biggest concern is the rise of antibiotic resistance from drugs entering water through household and agricultural waste. While not specifically about microplastics, the topic is connected because microplastics can adsorb and transport pharmaceutical residues through water systems.
Microplastics in freshwater wild and farmed fish species of Bangladesh
Researchers evaluated microplastic contamination in freshwater wild and farmed fish species across multiple rivers and farms in Bangladesh, comparing contamination levels between wild-caught and aquaculture-raised fish of the same species.
Profiling of Antibiotic Residues in Surface Water of River Yamuna Stretch Passing through Delhi, India
Researchers detected antibiotic residues in the River Yamuna passing through Delhi, with ofloxacin found at the highest concentration (145 ng/mL), and observed significant seasonal and spatial variation linked to hospital discharge, drug manufacturing, and agricultural runoff.
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.
Antibiotic resistance in aquaculture and aquatic organisms: a review of current nanotechnology applications for sustainable management
Researchers reviewed how antibiotics released from aquaculture and other industries accumulate in aquatic ecosystems, promoting antibiotic resistance, and assessed nanotechnology-based interventions — including nanodrug delivery, nanoformulations, and nanosensors — as promising tools for sustainable management of these emerging contaminants.
Unveiling the microplastic crisis: Insights into Bangladesh's aquatic ecosystems - origins, impact, and solutions
This review examines the growing microplastic crisis in Bangladesh's rivers, estuaries, and coastal waters, finding that the country's rapid urbanization and limited waste management have led to widespread contamination. Microplastics were documented in water, sediment, and fish across multiple Bangladeshi water systems. Since over 160 million people in Bangladesh depend on these water resources for drinking, farming, and fishing, the contamination poses a significant public health concern.
Presence of Microplastics and Organic Pollutants in Bangladesh's Freshwater Environment: A Review
This review examines microplastic and organic pollutant contamination in Bangladesh's freshwater environments, highlighting that microplastics act as vectors carrying other toxic substances into aquatic food webs. Given the heavy reliance on freshwater resources in Bangladesh, this dual contamination threat poses serious risks to both ecosystem health and human food safety.
A Review of Antibiotics, Antibiotic Resistant Bacteria, and Resistance Genes in Aquaculture: Occurrence, Contamination, and Transmission
This review examines how overuse of antibiotics in fish farming leads to antibiotic-resistant bacteria and resistance genes that spread through water, sediment, and the organisms themselves. This is relevant to microplastic pollution because microplastics in aquaculture environments can carry antibiotic-resistant bacteria, potentially transferring these dangerous genes to humans through the food chain.
Microplastics in fish culture ponds: abundance, characterization, and contamination risk assessment
Researchers surveyed five types of fish farming ponds in Bangladesh and found microplastics in all sediment and water samples, with higher contamination near industrial areas. The most common microplastics were small fragments and fibers made of polyethylene and polypropylene, likely originating from packaging waste and fishing gear. The findings raise concerns about microplastic contamination in farmed fish that are destined for human consumption.
Integrated analysis of microplastics origins and impact on prominent aquaculture ecosystems in Bangladesh
Researchers surveyed microplastic contamination in aquaculture ponds in Bangladesh, finding widespread particles in both the water and farmed fish including tilapia and pangas. Fibers were the most common type, likely from textile and fishing net waste, and the contamination levels posed potential health risks to consumers. Since farmed fish is a major protein source in Bangladesh and many developing countries, these findings highlight a direct pathway for microplastics to reach people through their diet.
Microplastics in aquaculture ponds of Bangladesh: Source attribution, pollution load, and ecological risk assessment
A survey of aquaculture ponds in Bangladesh's Jashore district found significant microplastic contamination in both surface water and sediments, with fibers and fragments being the dominant forms and polyethylene the most common polymer. The study identifies aquaculture ponds as underappreciated microplastic sinks that may pose risks to farmed fish and ultimately to people who eat them. Given Bangladesh's heavy reliance on pond aquaculture for food security, the findings raise important concerns about the safety of locally farmed seafood.
Proclivities for prevalence and treatment of antibiotics in the ambient water: a review
This review critically examines the prevalence of antibiotics in ambient water systems and the challenges of treating antibiotic-contaminated water. Researchers found that antibiotic resistance in water environments has emerged as a major public health concern, driven by pharmaceutical runoff and inadequate wastewater treatment. The study evaluates various treatment technologies and emphasizes the need for better monitoring and removal strategies to address this growing threat to water quality.
Interactions and associated resistance development mechanisms between microplastics, antibiotics and heavy metals in the aquaculture environment
This review explores how microplastics, antibiotics, and heavy metals interact in aquaculture environments to promote antibiotic resistance. Researchers found that microplastics can serve as carriers for both antibiotics and metals, creating hotspots where bacteria are more likely to develop resistance genes. The study underscores the compounding ecological and human health risks when these three types of pollutants co-exist in fish farming settings.
Ecological risk profiling of microplastic load in commercial aquaculture of Bangladesh: A multi-approach analysis across species-specific ponds
Researchers assessed microplastic contamination across five types of commercial fish ponds in Bangladesh, finding an average of about 520 particles per cubic meter of water. Pangas ponds had the highest contamination levels, and polyethylene and polypropylene were the most common plastic types. The study raises concerns about ecological risks to farmed fish in one of the world's leading aquaculture nations.
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.
