The increasing levels of industrialization and urbanization have led to the generation of significant amounts of wastewater and waste products, often containing chemicals like per- and poly-fluoroalkyl substances (PFASs) commonly found in consumer products. PFASs are known for their persistence, ubiquity, and ecotoxicological impacts, raising concerns about potential harm to ecosystems. This paper reports the occurrence and evaluates the ecological risks of PFASs in aquatic ecosystems and wastewater treatment works (WWTWs) across Africa.

- Microplastics (MPs) are widespread environmental pollutants that may carry harmful chemical contaminants like persistent organic pollutants (POPs), metals, and pharmaceuticals at significantly higher concentrations than in surrounding water.
- Evidence suggests MPs can also transport viruses, bacteria, and antibiotic-resistant genes, potentially affecting ecological health and influencing gene transfer among organisms.
- The review highlights important knowledge gaps, particularly regarding MPs as vectors for invasive species, and calls for further research to better understand their ecological impact.
Phosphate is considered the main cause of eutrophication and has received considerable attention recently. Several methods have been used for removal of phosphates in water and these include biological treatment, membrane filtration processes, chemical precipitation, and adsorption. Adsorption technology is highly effective in the removal of phosphate from wastewater even at low phosphate concentrations.
