Seasonal Variability and Sex-Specific Accumulation of Trace Metals in Black Scorpionfish (Scorpaena porcus Linnaeus, 1758) from Izmir Bay (Aegean Sea), Türkiye: Implications for Human Health Risk Assessment

Year: 2025

Type: article

Abstract: This study investigates seasonal and gender-related variations in some metal (Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn) accumulation in black scorpionfish (Scorpaena porcus) from Izmir Bay (Aegean Sea, Türkiye) and assesses the associated human health risks. Samples, collected across four seasons from 2023 to 2024, were analyzed for element concentrations using inductively coupled plasma mass spectrometry (ICP-MS). Health risks were calculated using several models, including estimated weekly intake (EWI), target hazard quotient (THQ), total THQ (∑THQ), carcinogenic risk (CR), Se health benefit value (HBVSe), and the Metal Pollution Index (MPI). The results indicate that the consumption of black scorpionfish poses potential health risks, primarily due to the accumulation of manganese (Mn), lead (Pb), and mercury (Hg), which exceeded international permissible legal limits. Gender-based differences were observed, with males showing higher accumulation (p > 0.05); however, these differences were not statistically significant. In contrast, significant sex-based differences were identified specifically for cadmium (Cd), with concentrations exhibiting a statistically meaningful difference (p < 0.05). Seasonal variations were also apparent (p < 0.05). The carcinogenic risk (CR) analyses revealed that chromium (Cr) and nickel (Ni) levels surpassed carcinogenic risk thresholds. Furthermore, the MPI values provided additional insights into the overall metal pollution levels in the fish. These findings underscore the critical importance of monitoring metal pollution, revising fishery management strategies, and managing fish consumption to safeguard public health.
