Description:
Initially, heavy metals (HMs) were the naturally occurring component that appeared in the world. However, due to increased anthropogenic actions and behaviors, HM emissions have elevated significantly, gradually leading to severe HM contamination. Further, the presence of HMs in water bodies may result in bioaccumulation within various marine organisms, including seafood, and be transferred to humans through the food chain, provoking adverse health issues, thereby raising public concerns about food safety (Koduvayur et al., 2022). To date, recent studies have not focused on investigating the risk related to seafood consumption in the local Hong Kong market. Therefore, this study aimed to address that gap by measuring the HM concentration of the mostly consumed seafood in the Hong Kong market and assessing their potential health risks, including clam (Venerupis philippinarum), shrimp (Metapenaeus ensis), Pampano (Trachinotus carolinus), Golden Thread (Nemipterus virgatus), and Grass carp (Ctenopharyngodon idella). Both AAS and ICP-MS analytical approaches were applied to measure different HMs concentrations from the handled sample obtained from the local market. The results show that, beyond species differences, heavy metal concentration in seafood contributes to various factors, including their tissue parts, feeding habits, and types, in which bivalve mollusk has the overall highest contamination. Furthermore, the study compared the HM concentration against different established thresholds, showing that several species exceeded the standard limit from different regions. However, despite exceeding the threshold, they remain within the safe range, as followed by the guidance of the USEPA (2011) risk assessment. This indicates that the tested species do not pose any significant health impact on the human body
