“…The importance of a careful selection of the geographical origin of bivalves to be used in biomonitoring efforts is known, since this origin may imply in different bioaccumulation efficiencies (Hédouin et al, 2011), whereas contrasting metal depuration trends have been reported for the same elements (Roesijadi et al, 1984;Yap et al, 2004). Variable metal concentration trends have given support for the use of bivalves in monitoring metal concentrations and bioavailability in the aquatic environment (Amaral et al, 2005;Birch;Hogg, 2011) and on the factors affecting the net metal uptake and safe use of bivalves for human consumption (Anacleto et al, 2015;Wang;Lu, 2017).…”

“…Pada tiram yang hidup di perairan tercemar, Cu dan Zn dalam konsentrasi tinggi berikatan dengan oksigen atau nitrogen, sedangkan pada tiram yang hidup di lingkungan yang relatif bersih, kedua logam tersebut berikatan dengan sulfur. Hal tersebut memungkinkan tiram dapat secara efisien melakukan detoksifiksi, dengan cara menyimpan kelebihan Cu dan Zn dalam bentuk logam-logam yang berikatan dengan oksigen dan nitrogen dalam tubuh tanpa berakibat fatal bagi kehidupannya (Wang & Lu, 2017).…”

“…Remis sering digunakan dalam pemantauan pencemaran Cd, meskipun apabila dibandingkan dengan tiram, bivalvia golongan remis (mussels) memiliki potensi bioakumulasi Cd yang rendah, yang disebabkan kemampuan mengeluarkan logam tersebut dari dalam tubuh secara lebih efektif. Hal ini menyebabkan konsentrasi Cd dalam remis lebih rendah daripada dalam tiram (Wang & Lu, 2017 (Wang & Lu, 2017). Pada beberapa penelitian konsentrasi Ni dalam remis berkisar antara <5 sampai 33 µg/g sedangkan konsentrasi Pb dalam remis pada umumnya sebesar <5 sampai 59-64 µg/g.…”

POTENTIAL OF BIVALVE AS BIOINDICATOR OF METAL POLLUTION IN THE COASTAL AREA. Bioaccumulation database using various species of marinebivalves is useful to determine which species are suitable as bioindicators in pollution monitoring. In general, metal bioaccumulation in bivalve varies in every location and influenced by the biokinetics of each species depending on the environmental condition. Increasing accumulation of one metal will enhance the accumulation of other metal in bivalve tissue. This needs to be taken into account in interpreting metal concentrations in bivalve. Oysters and mussels have the potential as bio-indicators of metals, especially Cu and Zn, while scallops are more potential as bioindicators of Cd and Zn. Meanwhile, clams has the potential as a bioindicators of Zn. Change in shape (malformation) of bivalve shells due to heavy metal accumulation also observed. The rough structure, attachment of minerals to the shell, and thickening of the shell layer are some forms of changes in bivalve shell morphology.

Contaminant substances consist of chemical elements that present the potential to adversely impact the ecology of the environment, thus representing a threat to local fauna and flora. In this context, heavy metals are critical agents that, depending on the nature and level, are potentially toxic to living organisms. In order to evaluate the bioaccumulation of heavy metals in the Santos estuary and to determine the potential influence of salinity gradient on the heavy metal bioconcentration, the present study measured the concentrations of As, Cd, Pb, Cu, Cr, Fe, Ni, and Zn in two bivalve species (Crassostrea rhizophorae and Perna Perna) sampled at different sites of Santos Bay, in the southeastern region of Brazil. Throughout the study, the “sentinel species” used were effective in bioaccumulating contaminants. In oysters, based on the Brazilian legislation, critical limits were exceeded for As, Zn, Cu, and Cr. In the case of mussels, on the other hand, only for As, Zn, and Cr, the critical limits were overcome. In the present study, obtained data suggested salinity as a determinant parameter in As incorporation processes of bivalve mollusks. Practitioner Points The present study presents important results for the development of environmental management policies in estuarine environments. The present study points out differences between different organisms as biomonitors, providing subsidies for the decision of an effective biomonitoring program. The present study discusses values of contaminants as a danger to public health in Santos Bay, which can be extrapolated to other similar environments around the world.
