Recent research conducted by Kristi Haka from the University Aleksander Xhuvani in Albania has shed light on the quality of marine biota in the Vlora region, particularly concerning the presence of heavy metals. This study, published in the Journal of Ecological Engineering, highlights the ongoing environmental challenges faced by marine ecosystems, which have been increasingly contaminated by various pollutants, including agricultural runoff, domestic waste, and emissions from ships.
The focus of the research was on 24 species of marine life, specifically analyzing the edible parts for heavy metal concentrations. The findings revealed that, with the exception of cadmium (Cd), the levels of heavy metals in the fish species examined did not exceed the permissible limits set by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO). This indicates that these fish are safe for human consumption, which is a positive outcome for both public health and the local fishing industry.
Haka noted, “The Estimated Daily Intake (EDI) of the selected species was lower than the Daily Reference Intake (DRI), while low values of target hazard quotient (THQ < 1) showed that the consumption of mussels containing heavy metals would not cause significant health risks to humans." This data is encouraging for consumers and businesses involved in seafood, as it reassures them about the safety of their products. The implications of this research extend beyond public health; they also present commercial opportunities. The seafood industry in Albania, particularly in the Vlora region, can leverage these findings to promote their fish and shellfish products. With growing global demand for safe and sustainable seafood, the ability to demonstrate that local marine life meets international safety standards could enhance marketability and consumer trust. Furthermore, the study emphasizes the importance of ongoing monitoring of metal concentrations in coastal areas. This not only aids in maintaining biodiversity but also ensures the quality of life for communities reliant on these marine resources. For stakeholders in environmental management, fisheries, and public health, the research underscores the need for continued vigilance and proactive measures to safeguard marine ecosystems. As the marine environment continues to face pressures from human activity, studies like Haka's play a critical role in informing policy and guiding sustainable practices. The findings presented in the Journal of Ecological Engineering serve as a valuable resource for understanding the health of marine biota and for making informed decisions that benefit both the ecosystem and the economy.
