The Sea of Marmara hosts a substantial population of gurnard fish species, which are commonly consumed throughout the year. Given the presence of agricultural, industrial, and transportation activities in this region, it is vital to study mercury (Hg) accumulation in these fish species to ensure safe consumption. This study was conducted to determine the total Hg concentrations in Tub gurnard and Piper gurnard fish caught off the coast of Yalova in the Marmara Sea and to assess their potential health outcomes. Mercury concentrations in the examined fish samples were assessed using a mercury analyzer (DMA-1). The mean concentrations of mercury (Hg) measured were 0.870 mg/kg for the piper gurnard and 0.299 mg/kg for the tub gurnard. Notably, Hg levels in the tub gurnard remained within the regulatory limits, whereas those in the piper gurnard exceeded the prescribed thresholds. Regarding dietary exposure, the estimated weekly intake (EWI) for tub gurnard was below the recommended limit (provisional tolerable weekly intake, PTWI), while for piper gurnard, it exceeded the recommended limit. Additionally, the Target Hazard Quotient (THQ) and hazard index (HI) estimated for the piper gurnard surpassed the recommended safety thresholds for Turkish consumers across the different body weight categories. This indicates a potential risk associated with the consumption of the piper gurnard in the Marmara Sea Region. The study outcomes underscore the necessity for consistent monitoring of Hg concentrations in these benthic fish species.
