“…Importantly, T-Hg levels in fish in this study were relatively higher, compared to other studies [16,[34][35][36][37][38][39]. While the shellfish and cephalopod T-Hg level were not higher, compared to other literatures [16,34,36,40].…”

Seafood is recognized as the high protein source of human consumption. However, it is hampered by mercury contamination. The objectives of this study are to determine total mercury (T-Hg) levels in edible portions of commercial seafood available in Bangkok’s supermarkets, and to evaluate the potential risks from mercury through seafood consumption. Total 32 species, including 22 fish, 4 cephalopod and 6 shellfish, were purchased from super-markets. Fish samples were dissected in 3 parts comprised of flesh, gill and viscera. While, cephalopod and shellfish were separated for edible tissues. The samples were digested in hot acid and were determined using cold-vapor atomic absorption spectrometry technique. The results revealed that T-Hg contained in the fish flesh > cephalopod > shellfish. In addition, T-Hg was accumulated in flesh > viscera > gill. Statistical analysis suggested that T-Hg accumulated in flesh was related positively with species, feeding habit, and habitat (p < 0.05). For risk analysis, estimated daily intake (EDI) of flesh ranged from 0.01 to 0.42 µg kg-1 bodyweight d-1, the lowest and highest EDI values were in salmon and yellowfin tuna, res-pectively. Yellowfin tuna, narrow-barred Spanish mackerel, fourfinger threadfin, and silver sillago were the 4 species that having the EDI values of T-Hg higher than the FAO/WHO recommended provisional tolerable daily intake (PTDI) of 0.23 µg kg-1 bodyweight d-1. Thus, the frequent consumption of these seafood are not recommended. In addition, the daily consumption of seafood should not exceed the maximum safe daily intake (MSDC). The MSDC of seafood in this study ranged from 15.5 (yellowfin tuna) to 474 (salmon) g d-1.

“…Moreover, significantly higher ( P < 0.05) levels of Hg were present in kidneys compared to the other samples, thereby, illustrating that kidneys are the main organ for Hg accumulation. Additionally, it is widely reported that fish and marine mammals can easily accumulate Hg through the food chain (García‐Hernández et al., ; Soares et al., ), and the use of fish meal as pig feed can also lead to higher Hg levels in pork products (CAC, ).…”

The concentrations of heavy metals, such as chromium (Cr), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb), in different muscles and edible offal of consumed pork from the city of Nanjing and related health risks were evaluated. The results showed that the detected Hg concentrations from 6 of 80 samples exceeded the maximum allowable concentration (GB 2762(GB -2017. Moreover, most of the edible offal, especially the kidneys, contained more heavy metals than the other parts, although the concentrations among the samples were significantly different (P < 0.05). In addition, the health risk evaluation revealed that the estimated daily intake of all the samples was far below the recommended limit, and all the target hazard quotients and total target hazard quotients were less than 1, which is considered safe for human health. Nevertheless, the Hg concentrations over the acceptable limit should receive sufficient attention, considering the long-term consumption of pork.Keywords: estimated daily intake, heavy metals, pork, risk assessment, target hazard quotient Practical Application: Currently, no reports have been available on the heavy metal assessment of pork, though pork is widely consumed in many non-Muslim communities. In this study, the concentrations of heavy metals in different muscles and edible offal of consumed pork were determined and their related health risks were evaluated. This study will provide a significant reference to understand the quality and safety of pork in China or other similar developing countries.

“…Heavy metal contamination is becoming a major con-cern in coastal systems, which are often associated with shrimp farming activity (Syakti et al 2015), due to the ability of heavy metals to persist in the environment (Ju et al 2017). Heavy metals are also toxic at high concentra-tions (Sfakianakis et al 2015) and could pose risks to hu-man health (Fakhri et al 2018;Garcia-Hernandez et al 2018;Zhang et al 2018), which is why exposure must be evaluated.…”

The occurrence and contamination level of seven important toxic metals (Cd, Cu, Co, Cr, Hg, Pb, and Zn) and three additional metals (Al, Fe, and Mn) in the water, sediment, and shrimp muscle in aquaculture areas located in Central Java, Indonesia, were investigated. The results suggest that the majority of metals have higher concentrations in the inlet followed by the outlet and ponds. Cd dissolved in the waters exhibited the highest level in Pekalongan (3.15 ± 0.33 μg L −1). Although Pb was not detected in the water, it was detected in the sediment, and the concentration ranged from 7.6 to 15.40 mg kg −1 dw. In general, the heavy metal concentrations in the sediments were found to decrease in the sequence Al > Fe > Mn > Zn > Cr > Cu > Co > Pb.Concentrations below the effects range low level based on the Canadian sediment quality guidelines were found for Cr, Cu, Pb, and Zn, whereas moderate sediment pollution (25-75 mg kg −1 dw) was observed for Cr (all regions), Cu (except in the Pekalongan region), and Zn (Brebes and Tegal regions) according to the US EPA standard. The status of the waters was evaluated by calculating a pollution index derived mostly from Mn and Zn. The ecological risk (geoaccumulation index (I geo ), contamination factor (CF), pollution load index (PLI), and potential ecological risk index (ERI)) determined in the sediments indicated that all studied areas had low to moderate contamination. The concentrations of all metals in shrimp were generally below the maximum limits for seafood, except for Zn (in all stations), Pb, and Cr (Tegal and Pekalongan). The hazard index values for metals indicated that consuming shrimp would not have adverse effects on human health.
