“…As in the case of C. glaucum and insect larvae, the higher Hg TOT levels, measured in Oligochaetes, Corophium sp. and H. diversicolor in Osłonino, were associated with increased Hg TOT concentration in their diet (Table 3 ; Table SIII )—the surface sediments in the case of Oligochaetes (van de Bund et al 1994 ; Rodrigues and Reynoldson 2011 ); suspended matter, microalgae and sediments in the case of Corophium sp. (Olenin and Daunys 2005 ; Riisgård and Schotge 2007 ); and sediments and microalgae in the case of H. diversicolor (Olivier et al 1995 ; Olenin and Daunys 2005 ).…”

Mercury (Hg) is a global pollutant that affects human and ecosystem health. Hg is a serious threat especially for the marine environment, in which it undergoes bioaccumulation and biomagnification, reaching elevated concentrations in fish and other seafood. The research aimed at investigating the trophodynamics of Hg in the basal links of the marine food chain: benthic macrofauna and its main food sources (i.e. suspended and sediment organic matter, micro- and macrophytobenthos). The results showed that both the amount and the origin of organic matter affected the Hg level in particular trophic groups of macrozoobenthos. The intensive inflow of terrestrial material influenced the enrichment of suspended particles and microphytobenthos in Hg, leading to increased Hg concentrations in filter-feeding macrofauna. The input of Hg-rich marine matter transported from the deeper parts of the Gulf of Gdańsk along with the near-bottom currents caused higher Hg levels in deposit feeders. The biomagnification factor (BMF) of Hg through benthic food web was dependent on environmental conditions occurring in the studied areas, in particular, factors favouring the growth and fecundity of macrofauna. Consequently, as a result of biodilution, the trophic transfer of Hg was less effective in a more productive region, despite the elevated Hg concentrations in dietary components of the macrofauna and in the surrounding environment.

“…T. tubifex is widely distributed, abundant in temperate regions, and easy to culture under laboratory conditions. It has been used in toxicity studies as a test organism for a long time [ 18 ], its relevance has been pointed out by Chapman [ 19 ], and there are standardised test methods that include this species to study the effects of hazardous chemicals [ 20 , 21 ], among others, toxicity tests for As, in both water-only and sediment exposures [ 22 , 23 ].…”

A toxicogenomic approach was used for toxicity evaluation of arsenic in the aquatic environment, and differential gene expression was investigated from 24 h and 96 h water-only acute toxicity tests with the aquatic oligochaete, Tubifex tubifex (Annelida, Clitellata). Several toxicological endpoints (survival and autotomy) of the oligochaete and tissue residues were measured, and dose-response modelling of gene expression data was studied. A reference transcriptome of the aquatic oligochaete, T. tubifex, was reconstructed for the first time, and genes related to cell stress response (Hsc70, Hsp10, Hsp60, and Hsp83), energy metabolism (COX1), oxidative stress (Cat, GSR, and MnSOD), and the genes involved in the homeostasis of organisms (CaM, RpS13, and UBE2) were identified and characterised. The potential use of the genes identified for risk assessment in freshwater ecosystems as early biomarkers of arsenic toxicity is discussed.
