ClearOccurrence, 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 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.
The occurence of pharmaceuticals and other micropollutants in wastewater treatment plant in the aspect of interaction with microplastics
Researchers analysed the occurrence of antibiotics, virucidal, and fungicidal pharmaceuticals in raw and treated sewage at a wastewater treatment plant in southern Poland, examining their removal efficiency and potential interactions with microplastics present in the effluent. The study found that pharmaceutical micropollutants persisted through treatment to varying degrees, raising concerns about combined contamination pathways when microplastics act as co-vectors for these compounds.
Pharmaceutically active micropollutants: origin, hazards and removal
This review summarizes existing research on pharmaceutical pollutants -- such as antibiotics, painkillers, and hormones -- found in water systems around the world. While focused on drug contamination, the paper notes that microplastics can act as carriers for these pharmaceutical chemicals, potentially concentrating them and increasing human exposure through drinking water. Conventional water treatment methods are often unable to fully remove these micropollutants.
Occurrence and ecological risks of pharmaceuticals in a Mediterranean river in Eastern Spain
Researchers monitored a Spanish Mediterranean river and detected up to 69 pharmaceutical compounds in the water, with painkillers and antibiotics posing the highest ecological risk — affecting an estimated 65–82% of aquatic species in areas near wastewater treatment plant outflows. Five antibiotics exceeded thresholds linked to antibiotic resistance, raising concerns that standard wastewater treatment is insufficient to protect river ecosystems.
Characterization of microplastics and their interaction with antibiotics in wastewater
Researchers characterized microplastics in wastewater and investigated their interactions with antibiotics, examining how microplastic surfaces adsorb antibiotic compounds and the implications for antibiotic transport and dissemination in wastewater treatment systems.
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.
A systematic review of sources, occurrence, behavior and risks of global marine antibiotics
This systematic review of global marine antibiotic contamination found that sulfamethoxazole is the most frequently detected antibiotic in seawater, sediment, and marine organisms, with the highest concentrations along coastal China. Coexisting contaminants like microplastics may enhance antibiotic impacts and drive antibiotic resistance gene development in marine environments.
Occurrence, Bioaccumulation, Metabolism and Ecotoxicity of Fluoroquinolones in the Aquatic Environment: A Review
This review examines fluoroquinolone antibiotic contamination in waterways across 32 countries, finding widespread pollution especially in developing nations. These antibiotics accumulate in aquatic organisms and move through the food chain, with toxicity varying by species and environmental conditions. The co-occurrence of antibiotics and microplastics in water is a growing concern, as microplastics can absorb and transport these drugs, potentially increasing human exposure.
Impact of wastewater treatment plant effluent discharge on the antibiotic resistome in downstream aquatic environments: a mini review
This review summarizes how wastewater treatment plants release antibiotic-resistant bacteria and resistance genes into rivers and lakes through their treated water. Current treatment processes cannot fully remove these resistance factors, allowing them to spread in downstream water bodies and potentially reach humans through drinking water and the food chain. The review is relevant to microplastics research because microplastics in wastewater can serve as surfaces where resistant bacteria grow and spread.
