The release of chemicals into the environment presents a significant threat to aquatic ecosystems dependent on proximity emission sources and seasonal dynamics mobilization. While spatial-temporal information water pollution in Europe is increasing, there are substantial knowledge gaps tropical countries. Thus, we took Lake Victoria South Basin western Kenya as case study identify spatial hot spots contamination, quantified toxic risks different groups organisms, identified risk drivers. For this purpose, analyzed grab samples from five rivers with agricultural wastewater treatment plants their catchment four seasons. We used liquid chromatography coupled high resolution mass spectrometry (LC-HRMS) target list 785 organic micropollutants. A total 307 compounds were detected concentrations ranging 0.3 ng/L 6.6 μg/L. Using Toxic Unit (TU) approach based mixture toxicity standard test crustaceans most affected group followed by algae fish. crustaceans, chronic thresholds exceeded 96 % all samples, while 56 expected be acutely toxic, highest February during dry season. High unit values for fish recorded July season May wet Diazinon, imidacloprid, clothianidin pirimiphos-methyl major drivers crustacean triclosan herbicide mixtures drive seasons, respectively. 18 found exceed acute environmental thresholds. With study, strong patterns pollution, could confirmed informing prioritization monitoring abatement enhance quality reduce risks.
