“…The ability of B. spirata to accumulate Plutonium as Pu 3+ and Pu 4+ in the environment is influenced by internal and external factors. Internal factors are the active side of cell membranes belonging to B. spirata as metal-binding molecules, while external factors are pH, salinity, particulate content, and dissolved organic matter content [30,32]. The organic particulates are eliminated by filtering the seawater, while other external factors are ignored because the seawater comes from the waters of Jakarta Bay [33].…”

The research of bioaccumulation Plutonium of Babylonia spirata from Jakarta Bay using 242Pu radiotracer has been conducted. The aquaria experiments were applied by two oxidation states of Pu speciation with three replications. The experiment was carried out by 2 steps, such as uptake and depuration. The bioavailability of 242Pu in the (III) and (IV) oxidation states from sea has been studied for Babylonia spirata. Biokinetics parameters, such as concentration factors (CFss), uptake rate constants (ku), elimination rate constants (ke), bioconcentration factors (BCF), and biological half-life (tb1/2), were investigated. The dissection is carried out to separate the parts of the gastropod's body so that the target organs for Plutonium contamination can be identified. Each part of the gastropod's body was prepared radiochemically and analyzed using an alpha spectrometer. The research shows that Pu4+ is potentially accumulated in greater value than Pu3+ by B. spirata, in which Pu is more rapidly distributed and retained longer in proboscis and gastrointestinal tract.

“…Berbagai studi bioakumulasi dan distribusi 242 Pu oleh biota laut masih terbatas. Studi bioakumulasi plutonium kebanyakan dilakukan berdasar pemantauan lingkungan (Melinda et al, 2015). Wilson et al (2009) melakukan eksperimen bioakumulasi untuk mengetahui konsentrasi radionuklida plutonium pada sampel plankton yang dikumpulkan di Laut Irlandia Timur.…”

Operasional fasilitas nuklir yang ada di Serpong memungkinkan melepas radionuklida ke lingkungan. Isotop Pu merupakan radionuklida yang terlepas ke lingkungan. Lepasan tersebut terbawa oleh air sungai atau run off memasuki Teluk Jakarta. Kerang hijau (Perna viridis) mampu mengakumulasi radionuklida tersebut. Studi ini bertujuan untuk memahami kinetika proses bioakumulasi Pu oleh kerang hijau yang dipengaruhi oleh spesiasinya. Percobaan dilakukan melalui tahapan: aklimatisasi, bioakumulasi (242Pu3+ dan 242Pu4+) dan depurasi. Parameter biokinetika diamati meliputi faktor konsentrasi (CF), konstanta laju pengambilan (ku), konstanta laju pelepasan (ke), faktor biokonsentrasi (BCF), dan waktu paruh biologis (tb1/2). Berdasarkan uji statis non parametric menunjukkan spesiasi 242Pu3+ dan 242Pu4+ berpengaruh terhadap kemampuan Perna viridis mengakumulasi Pu. Rerata kemampuan bioakumulasi 242Pu4+ oleh Perna viridis adalah 1,2 kali dibandingkan 242Pu4+. Kata kunci : Bioakumulasi , biokinetika, Perna viridis, plutonium, spesiasi, Perna viridis, plutonium. Operations of nuclear facilities in Serpong have potentially release radionuclides to environment. Pu isotope is one of radionuclide that is released into the environment. The release of this radionuclide was carried by the river water or run off entered the Bay of Jakarta. Green mussels (Perna viridis) can be accumulate this radionuclides. The aims of this study was to understand of the biokinetic of Pu bioaccumulation process by green mussels which are affected by its speciation. The experiment was carried out through stages: acclimatization, bioaccumulation (242Pu3+ and 242Pu4+) and depuration. Biokinetic parameters was observed include concentration factor (CF), uptake rate constant (ku), release rate constant (ke), bioconcentration factor (BCF), and biological half-life (tb1/2). Base on non parametric statistic test shown that speciation of 242Pu3+ and 242Pu4+ had an effect on the ability of Perna viridis to accumulate Pu. Avarage of bioaccumulation capabilities of 242Pu4+ by Perna viridis are 1.2 than 242Pu3+. Keywords: bioaccumulation, biokinetics, plutonium, Perna viridis, speciation.
