dc.description.abstractPersonal care products (PCPs) are emerging pollutants which have been detected in aquatic environments and are potentially toxic to aquatic organisms. The acute toxicity of two (2) PCPs - sodium lauryl sulfate (SLS) and sodium tripolyphosphate (STPP) to fingerlings of Clarias gariepinus (the African Sharptooth Catfish) was evaluated over a period of 96 h. Furthermore, genotoxic (erythrocytic micronuclei frequencies) evaluations were conducted in juveniles of C. gariepinus exposed to sublethal concentrations of the test chemicals over a period of 28 days. The median lethal concentration of SLS and STPP to C. gariepinus was 14.75 mg/L and 861 mg/L respectively with SLS being x59 more toxic than STPP to C. gariepinus. Micronuclei frequencies in SLS-exposed fishes were significantly higher (p<0.05) at day 14 (3.44±1.08 ‰) and day 28 (5.78±1.18 ‰) compared to the control (day 14- 0.78±0.22 ‰; day 28- 1.56±0.29 ‰). However, in STPP-exposed fishes, micronuclei frequencies were significantly higher (p<0.05) at day 28 (4.11±0.89 ‰) only compared to the control. The study showed that non-target aquatic animals such as C. gariepinus might be at risk from exposure to these chemicals in surface waters from diffuse sources with SLS posing a higher risk than STPP. Targeted environmental management and advocacies are recommended to promote sustainability of life below water (United Nations Sustainable Development Goal 14).en_US
