Veterinary pharmaceuticals in aqueous systems and associated effects: an update

Area of Science:

• Environmental Science
• Ecotoxicology
• Aquatic Chemistry

Background:

• Pharmaceuticals are emerging contaminants in aquatic environments, including groundwater and surface water.
• Wastewater from sewage plants, hospitals, and pharmaceutical industries contribute to contamination.
• Increasing evidence links veterinary pharmaceuticals from animal facilities to aquatic ecosystem pollution.

Purpose of the Study:

• To review scientific evidence connecting veterinary pharmaceuticals to aquatic contamination.
• To highlight the adverse effects of these contaminants on aquatic biota.
• To propose strategies for reducing veterinary pharmaceutical residues in aquatic habitats.

Main Methods:

• Literature review of environmental studies and epidemiological data.
• Analysis of scientific evidence on pharmaceutical occurrence in aqueous matrices.
• Synthesis of information on the impacts of veterinary drugs on aquatic ecosystems.

Main Results:

• Significant concentrations of veterinary pharmaceuticals found in wastewater near animal production facilities.
• Established correlation between veterinary drug exposure and adverse effects in aquatic organisms (endocrine disruption, antibiotic resistance, neurotoxicity, genotoxicity, oxidative stress).
• Aquatic ecosystem integrity is threatened, potentially impacting global ecosystems and food chains.

Conclusions:

• Veterinary pharmaceutical contamination poses a significant risk to aquatic environments and biota.
• Monitoring and mitigation strategies are essential to reduce the environmental burden of veterinary drugs.
• Protecting aquatic habitats from pharmaceutical pollution is vital for ecosystem health and human food security.
