Our findings provide new evidences about the role of Priolo sediments as a sources of pollutants for the food web, representing a threat to fish and, by domino effect, to humans.Ĭopyright © 2017 Elsevier Ltd. The positive slope and the higher TMF indicated active biomagnification in this benthic food web due to the high bioaccumulation efficiency of this benthic predator. Interestingly, different Cd behaviour was found considering only the benthic pathway which leads to the predatory gastropod Hexaplex trunculus. δ 15N of sources and consumers and the trophic magnification factors (TMFs) of 1.22 and 0.83 respectively. T-Hg and Cd were found to biomagnify and biodilute respectively based on the significant linear regressions between log and log vs. Biomagnification was then assessed, including basal sources (surface sediment, macroalgae), zooplankton, benthic invertebrates and fish.

Trophic pathways were first characterised in the Priolo Bay food web using carbon and nitrogen stable isotopes (δ 13C, δ 15N) and a single main trophic pathway characterised the Priolo Bay food web.

'to rearm' c Reverso Context: On each occasion, the LTTE used cessation of hostilities to rearm, regroup and strengthen its offensive capabilities. Cd showed the opposite pattern, in line with the higher trace element (TE) excretion rates of high trophic level fish and the lower level of Cd environmental contamination. T-Hg concentration was found to significantly increase along δ 15N and from pelagic to benthic sedentary fish, revealing a marked influence of trophic position and habitat use (sensu Harmelin 1987) on T-Hg accumulation within ichthyofauna. Adult and juvenile fish were caught in 2012 in Priolo Bay, south of the Augusta harbour (Central Mediterranean Sea), which is known for the high trace element and polycyclic aromatic hydrocarbon contamination level. Total mercury (T-Hg) and cadmium (Cd) were measured in twenty species of fish to study their bioaccumulation patterns and trophodynamics in the Augusta Bay food web.
