Differences (x ± SD) in the content of mercury (mg/kg wet weight) in muscle tissue of fish and indices (THQ and HI).
| Hg | THQ | HI | |
|---|---|---|---|
| Tench (Tinca tinca L.) | 0.082 ± 0.068 ab | 0.1578 | |
| Lake trout (Salvelinus namaycush Walb.) | 0.024 ± 0.002 c | 0.0473 | |
| Flounder (Platichthys flesus L.) | 0.044 ± 0.021 abc | 0.0847 | 0.684 |
| Gilthead seabream (Sparus aurata L.) | 0.092 ± 0.008 a | 0.1782 | |
| Crucian carp (Carassius carassius L.) | 0.033 ± 0.007 bc | 0.0635 | |
| Mackerel (Scomber scombrus L.) | 0.079 ± 0.016 ab | 0.1525 | |
| RfD (mg/kg/day) | 3.00 × 10−4 |
X—mean; SD—standard deviation; a, b, c —significant differences (p ≤ 0.05). The same letter indicates the absence of significant differences h (p > 0.05). RfD—oral reference dose (mg/kg/day) [34]; THQ—target hazard quotient; TTHQ—individual foodstuff; HI—hazardous index.
