“…Our study considered the MAL of Cr was 0.1 mg/kg ww according to the available permissible limit of Brazilian regulatory limit [ 56 , 58 ]. Additionally, there was no previous evidence for estimating the MAL of Cr using the wet weight of fish tissue, though some studies discussed its concentration given in dry weights (e.g., [ 60 , 61 ]). Therefore, the data obtained in this study cannot be compared.…”

Thirty-six elements are categorized as essential but toxic in excess amount (EBTEs), non-essential toxic (NETs), and Other in 29 different edible aquatic species dwelling in offshore pelagic, and coastal and estuarine (CE) ecosystems were investigated in Sri Lanka. Elements were analyzed using an energy-dispersive X-ray fluorescence (EDXRF) spectrometer, and an NIC MA-3000 Mercury Analyzer. EBTEs showed a negative relationship, whereas NETs showed a positive relationship between the concentration (mg/kg wet weight) and trophic levels in both ecosystems. EBTEs showed trophic dilution, whereas NETs showed trophic magnification. Some elements in a few organisms exceeded the maximum allowable limit which is safe for human consumption. There was a positive relationship (R2 = 0.85) between the concentration of mercury and body weight of yellowfin tuna (YFT). For the widely consumed YFT, the calculated hazard index (HI) for the non-carcinogenic health and exposure daily intake of NETs for adults were 0.27 and 9.38 × 10−5 mg/kg bw/day, respectively. The estimated provisional tolerable weekly intake (PTWI) (μg/kg bw/w) was 0.47 for arsenic and 0.05 for antimony, cadmium, mercury, and lead. The HI and PTWI values were below the recommended limits; thus, consumption of YFT does not pose any health risk for Sri Lankan adults.

“…Palmer et al (2010) report declines in numbers of invertebrate genera as sulfate concentrations from mountaintop mining increase. The increases in selenium noted above have been linked to teratogenic deformities in fish and reproductive failure in fish and in birds that consume the fish (Lemly, 2007).…”

“…2 All samples evaluated presented selenium concentration in muscle below the maximum allowable selenium concentrations, 2.00 µg g -1 wet wt., proposed by Lemly. 44 The muscle samples of cutlassfish presented selenium concentrations ranged from 0.0001 to 0.78 µg g -1 wet wt. (or from 0.0005 to 3.12 µg g -1 dry wt.).…”

Mercúrio e selênio foram determinados no tecido muscular do peixe espada (Trichiurus lepturus) de três áreas costeiras (Baía da Ilha Grande, Baía de Guanabara and Búzios, Estado do Rio de Janeiro) que apresentam diferentes condições ambientais, localizadas no sudeste brasileiro. Hg foi determinado por espectrometria de absorção atômica em vapor frio (CV-AAS) e Se por espectrometria de absorção atômica com forno de grafite (GF-AAS). As concentrações variaram de 0,44 a 0,87 µg Hg g -1 e de 0,0050 a 3,12 µg Se g -1 , em peso seco. Foram observadas diferenças significativas na concentração de mercúrio e na razão molar selênio:mercúrio entre as áreas. O comprimento total e os intervalos de tamanho influenciaram na acumulação de mercúrio, entretanto estes parâmetros biológicos não influenciaram na acumulação de selênio. Foi observado um excesso de selênio em relação ao mercúrio. Provavelmente, as diferenças regionais podem ser em parte atribuídas às diferenças nas condições ambientais (temperatura da água e produção primária), e também a outros fatores, tais como a escolha das presas e a disponibilidade destes elementos nos ambientes.Mercury and selenium were assessed in the muscle tissue of cutlassfish (Trichiurus lepturus) from three coastal areas (Ilha Grande Bay, Guanabara Bay and Búzios coast, Rio de Janeiro State, Brazil) that present different environmental conditions, localized in Southeastern Brazil. Hg was determined by cold vapor atomic absorption spectrometry (CV-AAS) and Se was determined by graphite furnace atomic absorption spectrometry (GF-AAS). Across sites, mercury and selenium in this fish ranged from 0.44 to 0.87 µg Hg g -1 and 0.0050 to 3.12 µg Se g -1 dry wt. Significant differences were observed in mercury concentrations and Se:Hg molar ratios among the areas. The total length and size intervals presented a significant influence on the accumulation of mercury, whereas this pattern was not observed for selenium. A large excess of selenium in relation to mercury was observed. Probably, the regional differences can be partly attributed to differences in the prevalent environmental conditions (water temperature and primary production), and also to other factors, such as prey choices and availability across locations.
