“…Brügmann and Lange (1988) reported mercury concentrations in A. rubens from the Western Baltic in the range 17-163 (mean 60±22) ng Hg g -1 dry weight (dw), comparable to the results of the present investigation (79±24) ng Hg g -1 dw. Soft parts of the potential prey items blue mussels Mytilus edulis and periwinkles Littorina littorea collected at the same location as the background sea stars of the present investigation contained 12.2±1.04 (n=28) and 13.3±0.5 (n=28) ng Hg g -1 ww, respectively (Bjerregaard et al, 2020) -also indicating lack of trophic magnification in the sea stars with 15±5 ng Hg g -1 ww. Thus, sea stars apparently do not concentrate mercury to higher concentrations than found in the food and this also appears to be the case for another benthic invertebrate predator, the shore crab C. maenas which in field investigations did not show highly elevated mercury concentrations compared to potential prey items: Coelho et al (2013) found 1330 ng Hg/g dw in the muscle of the shore crab and 900 and 2080/670 ng Hg, respectively, in the potential prey items the polychaete Hediste diversicolor and the clam Scrobicularia plana.…”

Bjerregaard et al (2020) also found lower mercury concentrations in the soft parts of C. maenas than in their potential prey items the periwinkle L. littorea and the blue mussel M. edulis, both at contaminated sites and sites with no history of mercury contamination.…”

“…However, other studies have reported conflicting results, with organisms containing greater Hg concentrations at higher Chl a concentrations and nutrient loadings (Todorova et al 2015; Chen et al 2021). It would be of interest to investigate how MARs relate to Hg concentrations in sediment and biota (e.g., Bodaly et al 1993; Bjerregaard et al 2020).…”

“…Baeyens et al 2005 ; Ridgway and Shimmield 2002 ). Therefore, it was somewhat surprising to find (Bjerregaard et al 2020 ) that the concentrations of mercury in the near-shore, coastal sediments along Harboøre Tange had decreased considerably since the 1980s.…”
