Freshwater killifish, Aphanius stoliczkanus, were collected from industrial and non-industrial areas in Oman to assess trace element levels muscle liver tissues estimate potential human health risks using the Estimated Daily Intake (EDI) Target Hazard Quotient (THQ). Samples obtained Al Amarart, Khawd, Surur analyzed Atomic Absorption Spectroscopy. Fish Amarart exhibited significantly higher concentrations of toxic elements, particularly arsenic (As), cadmium (Cd), lead (Pb), suggesting a strong influence activities. In contrast, fish Khawd lower, reflecting reduced anthropogenic inputs. almost all sites, most metals accumulated at than muscle, indicating increased bioavailability for essential elements or detoxifying function metals. Despite variation contamination levels, THQ values remained below threshold concern (THQ < 1), that individual exposure through consumption does not pose immediate risks. Similarly, calculated cancer risk (CR) As was within acceptable limits sites. However, while direct A. stoliczkanus appears low, cumulative effects multiple dietary environmental sources should be overlooked. Bioaccumulation trophic transfer water other food may long-term concerns. Overall, these findings highlight as valuable bioindicator regions. Continued monitoring stricter pollution control measures are recommended mitigate ensure safety. Further studies explore temporal trends additional toxicity biomarkers provide more comprehensive understanding ecological
