“…In this study, MT content in oysters from XZ was significantly higher than that from other sites. Several studies have found that MT content had positive correlations with metal concentrations in bivalves (Trombini et al, 2010;Khati et al, 2012). Furthermore, Cd, Cu and Zn were also regarded as an inducer of MT (Viarengo et al, 1997;Marigomez et al, 2002), which was consistent with the high levels of Cd, Cu and Zn at XZ site.…”

a b s t r a c t a r t i c l e i n f oArticle history: Received 9 January 2016 Received in revised form 26 July 2016 Accepted 29 July 2016 Available online xxxx An integrative biomarker approach was employed to evaluate the environmental quality of the north coast of Shandong Peninsula along the southern Bohai Sea of China, where pollution is an imminent threat due to rapid urbanization and industrialization. A battery of biomarkers and the metal bioaccumulation in tissues of native oyster Crassostrea gigas were measured under field conditions. Integrative biomarker index (IBR) and metal body burden were calculated to differentiate the pollution status of seven sampling sites. According to our results, Xinzhuang (XZ) site was the most severely contaminated, with the highest IBR value of 3.58, while the lowest IBR value (0.04) was obtained at Penglai (PL). Such an integrated biomarker approach was proved as a useful method for environmental quality assessment in the study area.

“…The digestive gland-gonad complex was the main storage tissue for all measured metals, except for Al in B. globulosus and T. geversianus (Table II). The digestive gland-gonad complex was proposed in previous works as a target for metal detoxification in many invertebrate species (Rainbow 2007), while metallothionein induction is reported as an effective detoxification mechanism in other marine invertebrates (Cheung et al 2002;Khati et al 2012).…”

High concentrations of metals are accumulated by edible marine resources, affecting human health. Marine gastropods have been commercially captured and consumed in Argentina for decades without official regulations or studies to guarantee their safety. In this study, metals (cadmium, aluminium, iron, zinc, copper and lead) were analysed for the first time in the edible marine gastropods Buccinanops globulosus, Adelomelon ancilla and Trophon geversianus and their surrounding sediments. Taking into account the maximum levels recommended by national and international regulations for food safety, we recommend consuming only the foot of these gastropod species. We recommend not consuming these gastropods from harbour areas due to concentrations of lead in sediments and tissues. Though the target hazard quotient (THQ) of cadmium was not high for the local community, it could be higher for other populations who consume molluscs more frequently, indicating a potential health risk of chronic exposure. Monitoring of these and other contaminants should be performed in order to ensure food safety of these marine resources. ARTICLE HISTORY

“…There is little information on metallothionein expression in rotifers, in spite of their widespread distribution in aquatic animals (Roesijadi, 1992). Metallothionein can be induced by the essential metals Cu and Zn and the non-essential metals Cd, Ag and Hg in both vertebrates and invertebrates, but their induction is variable (Amiard et al, 2006). Alvarado-Flores et al (2012) studied how lead is bioconcentrated and distributed in the rotifer Brachionus calyciflorus.…”
