“…The total arsenic content in the muscle tissues of ve specimens of tuna ranged from 4.0 to 5.8 mg As per kg with a mean total arsenic concentration of 4.7 AE 0.8 mg As per kg (n ¼ 5), respectively. These arsenic concentrations are similar to those reported for muscle tissues of various tuna species 30,31 and in canned tuna, 32 and are in accordance with arsenic concentrations commonly found in muscle tissue of marine sh. The total arsenic content in brain tissues of skipjack tuna, however, showed up to three-fold higher concentrations than in the muscle tissues of the same specimen, ranging from 9.1 to 17.4 mg As per kg with mean and median values of 12.2 and 10.9 mg As per kg (n ¼ 5), respectively, suggesting an accumulation of arsenic in the brain of this marine sh (Table 2 and ESI Fig.…”

“…To assess the risk of canned tuna, the estimated daily intake (EDI) of metal was determined using Eq. (4) ( Núñez et al., 2018 ).

where EDI is the estimated daily intake (mg/kg/day); F IR is the Daily fish tuna consumption rate (kg/person/day); C is the average of heavy metal concentrations in canned tuna (μg/g), and BW is the average body weight (70 kg).…”

One of the drawbacks of canning is the migration of various chemicals from the package into the food product. This work aimed at analyzing the concentrations of Bisphenol A (in 137 samples) and heavy metals (in 51 samples) of canned tuna commercialized in Lebanon while evaluating the variability across different brands, packing media, layer, and proximity to the expiry date. Accordingly, BPA was detected in 12 samples out of the 137 samples, run in duplicates. The estimated daily intake of BPA for the selected samples (n = 274) was lower than the tolerable daily intake of BPA, 0.004 mg/kg/day. Therefore, there is no health risk associated with BPA as a result of consuming canned tuna commercialized in the Lebanese market. Besides, the study has shown that 66 samples out of 102 were contaminated with Zn whereas 100% of the samples were contaminated with Aluminum and Tin. However, the calculated Health Risk Index of all the considered heavy metals are all within the safe limits as defined by EFSA (European Food Safety Authority) and Codex Alimentarius.

“…As with the hazard quotient, overall exposures below 1 calculated using hazard quotients are unlikely to result in any chronic systemic risk adverse health effects during a lifetime of exposure and would normally be considered as acceptable. The hazard index (HI) from THQs is expressed as the sum of the target hazard quotients (Núñez et al, 2018):…”

Total mercury (Hg) and methylmercury (MeHg) concentrations in the flesh of sardine (Sardina pilchardus) and swordfish (Xiphias gladius) fished in three Algerian coasts were determined by a direct mercury analyzer (DMA). We also assessed the risk to which the consumer was exposed to by calculating the estimated daily intakes (EDIs), target hazard quotient (THQ) and hazard index (HI). The average concentrations of Hg and MeHg in the flesh of sardine were similar (0.04 mg/kg wet weight) and in swordfish were 0.61 mg/kg wet weight; 0.57 mg/kg wet weight, respectively. These concentrations have not surpassed the thresholds set by the Algerian and European regulations. The estimated daily intakes for Hg and MeHg were similar in sardine (0.0064 μg/kg/day) and were 0.098 μg/kg/day and 0.092 μg/kg/day for Hg and MeHg, respectively, in swordfish. These values did not exceed the provisional tolerable weekly intake (PTWI) established by the European Food Safety Authority (EFSA) and by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). The target hazard quotient (THQ) and the hazard index (HI) calculated were < 1. Consequently, consumption of these fishes does not pose any risk for the adult groups of the Algerian population regarding mercury, and methylmercury studied.
