“…Mammals receptors may be indeed conserved in invertebrates but not always their specific function, leading to unexpected chronic effects in these organisms (Crane et al, 2006). The effects of pharmaceuticals exposure on freshwater and marine bivalves ranged from the molecular level, such as disturbed enzyme functions, DNA damage, and modulated gene expression (Contardo-Jara et al, 2011;Franzellitti et al, 2013;Gonzalez-Rey and Bebianno, 2013;Parolini et al, 2013;Quinn et al, 2011), to cellular level with increased oxidative stress, cytotoxicity and immunotoxicity (Aguirre-Martínez et al, 2013;Binelli et al, 2009;Canesi et al, 2007;Gagn e et al, 2006a;Gust et al, 2012;MartinDiaz et al, 2009;Matozzo et al, 2012;Munari et al, 2014;Parolini et al, 2011;Tsiaka et al, 2013) to the fitness of organisms with embryotoxicity Hazelton et al, 2013;Di Poi et al, 2014), reprotoxicity (Bringolf et al, 2010;Cortez et al, 2012;Fong and Ford, 2014;Hazelton et al, 2014;Lazzara et al, 2012) and decrease of feeding rate (Sol e et al, 2010). While the effect characterization has already been addressed as one of the big question of pharmaceuticals in the environment (Boxall et al, 2012), their effects on invertebrates remained sometimes controversial.…”
