Introduction: Fish consumption can be a primary pathway for human exposure to toxic metals such as, Cd, As, Hg, and Pb. Even at relatively low concentrations, long-term exposure to these metals might result in accumulation levels leading to toxicity. Therefore, monitoring their concentrations in fish regularly is crucial to ensure consumer safety. We aimed to measure the concentrations of As, Cd, Hg, and Pb in dierent fish and canned fish samples and to compare the results with permissible exposure limits to assess potential human health hazards.

Methods: Thirteen dierent fish species and eight canned fish samples were collected from local markets at Ramallah city, Palestine. Following microwaveassisted digestion, a high-resolution inductively coupled plasma-mass spectrometer (HR-ICP-MS) was used to measure the concentrations of these metals in the digested samples.

Results and discussion: The ranges of average metal concentrations [expressed in µg/g dry weight (dw)] in the 13 tested fish species were as follows: As (0.03– 54.27), Cd (
