“…In general, the highest Hg content in fish were detected in S2 ( S. aurata = 1853.7 ± 655.6 μg/kg d.w.; S. salpa = 2518.7 ± 231.8 μg/kg d.w.) ( Table 1 ); this value may be due to the wastewater from the sewage drains that polluted the seawater up to 200 m from the beach (WMC/TAP 2019). Few studies found that trace element concentrations in seagrasses were not significantly correlated with column waters [ 29 ]. Although seagrasses were able to uptake trace elements from water as well, our study showed high concentration in Posidonia oceanica was detected in S3 (plant =16.76 ± 4.48 μg/kg d.w.) than those in S4 (plant = 5.33 ± 0.05 μg/kg d.w.) and it was due to the localization of S3.…”

Total mercury (Hg) was determined in 450 environmental samples (seawater, sediment plant and fish) from five Mahdia coastal areas (Tunisia). Tolerable Weekly Intake% (TWI) values, according to the European Food Safety Authority (EFSA), were calculated based on the average metal concentration in fish and the average weekly fish consumption rate. Hg was accumulated mainly in fish and in Posidonia oceanica leaves. Hg in sediment ranged from 1.88 μg/kg dry weight (d.w.) to 7.48 μg/kg d.w., while it was between 0.32 μg/kg and 0.19 μg/kg in seawaters. Our study showed high concentration in Posidonia oceanica in S3 (plant = 16.76 ± 4.48 μg/kg d.w.) as compared to those in S4 sites (plant = 5.33 ± 0.05 μg/kg d.w.). Concentrations for S. aurata and S. salpa in the Rejiche area exceeded the EC 1881/2006 legislation with values of 1.9 mg/kg and 2.5 mg/kg, respectively, and consumers may be exposed to high concentrations of Hg that exceeds the EFSA. The results showed that the fish species should be constantly monitored due to their TWI% of 154.5% for S. aurata and 209.8% S. salpa respectively.

“…Here, bioaccumulation of MeHg measured in D. polymorpha at D1 and D7 corresponded to values found at moderately (≤0.4 mg•kg -1 dw) and highly contaminated sites (≤1.9 mg•kg -1 dw), respectively. For comparison, MeHg concentration reached 0.4 mg•kg -1 dw in Cerastoderma glaucum tissues (Dominik et al, 2014) and 0.21 mg•kg -1 MeHg dw in Crassostrea virginica (Apeti et al, 2012) in moderately contaminated sites. Besides, all values were <0.5 mg•kg -1 fw (i.e.…”

“…Trophic magnification factor (TMF) represents the transfer of 1 chemical from diet to consumer through food webs (Borga et al ). Trophic magnification factor was quantified using Equations 3, 4 (Dominik et al ; Guo et al ):

italicLog c = a + b \times δ^{15} normalN

TMF = 10^{b}

where c is the metal concentration in an organism and a and b are the intercept and slope of the regression. Trophic magnification factor >1 indicates a biomagnification of metal with increasing trophic levels, whereas TMF < 1 suggests a biodilution of metal in the present food web (Nfon et al ).…”

To estimate the risk of metal (Cu, Zn, Pb, and Cd) exposure of tree sparrows through food at different life stages (including nestling, juvenile, adult in summer, and adult in winter), metal daily intake (MDI), metal daily intake per unit of body weight (MDIBW), and exposure risks (hazard quotient and hazard index) of tree sparrows at different life stages from a polluted area, Baiyin, and a control area, Liujiaxia, were assessed. Metal daily intakes and MDIBWs of tree sparrows from Baiyin were higher than those from Liujiaxia, which can be attributed to higher metal concentrations of food sources in Baiyin than those in Liujiaxia. Metal daily intakes and MDIBWs of nestlings were higher than those of adults and juveniles. This difference is observed probably because nonphytophagous invertebrates, the predominant food fed to nestlings, possessed the highest metal concentrations. In addition, adults in summer had higher MDIs and MDIBWs than juveniles and adults in winter. This finding is probably observed because juveniles and adults in winter consumed a higher proportion of maize, which had the lowest metal concentrations. In addition, the biomagnification of 4 metals through the food chain increased the health risks of tree sparrows. Exposure risks of tree sparrows to metals were comparable to those of waterfowl and raptors, even when soil metals were below threshold. Environ Toxicol Chem 2019;38:2785–2796. © 2019 SETAC
