“…So far, research has focused on trace metal concentrations in the tissue of this bivalve to be used in biomonitoring, although concentrations in their shells have also been employed as a useful tool in biomonitoring (Bau et al, 2010;Bourgoin, 1990;Brown et al, 2005;Markich et al, 2002;Pearce and Mann, 2006;Weltje et al, 2002). However, vital effects may affect the specific incorporation of some elements into the shells relative to their concentration in ambient water (e.g., Takesue et al, 2008;Wanamaker et al, 2008) and may thus limit the applicability of certain proxies. Nevertheless, Corbicula shells appear to be a valuable bioarchive of physico-chemical conditions in freshwater environments (Bellotto and Miekeley, 2007;Bourgoin, 1990).…”
