ClearIssues of Non-Steroidal Anti-Inflammatory Drugs in Aquatic Environments: A Review Study
This paper is not primarily about microplastics. It reviews the occurrence and environmental fate of non-steroidal anti-inflammatory drugs (NSAIDs like ibuprofen and diclofenac) in aquatic environments, focusing on their incomplete removal by wastewater treatment plants and effects on aquatic organisms. While pharmaceutical pollutants and microplastics are both emerging contaminants in water, this study addresses drug contamination rather than microplastic pollution.
Pharmaceuticals Removal by Ozone and Electro-Oxidation in Combination with Biological Treatment
Researchers tested the combined use of ozonation and electrochemical oxidation for removing pharmaceutical contaminants from hospital wastewater. They found that the simultaneous application of both methods, following initial biological treatment, achieved complete degradation of refractory compounds and produced a non-toxic effluent. The study suggests this combined approach is a promising solution for treating pharmaceutical-contaminated wastewater from healthcare facilities.
