Abstract

ZAMBRANO, Mónica; PRADA, Jorge; ARENCIBIA, Gustavo  and  VIDAL, Alexis. BIOACCUMULATION OF NAPHTHALENE AND FLUORANTHENE IN THE BIVALVE MOLLUSC Anadara tuberculosa (Sowerby, 1833). rev.udcaactual.divulg.cient. [online]. 2012, vol.15, n.2, pp.283-290. ISSN 0123-4226.

The bioaccumulation of naphthalene and fluoranthene in the bivalve Anadara tuberculosa, was followed through the development of semistatic tests and exposure of organisms in individual tests for each compound at a concentration of 0.1mg/g for a period of 30 days. The highest level of naphthalene accumulated by the organisms reached 3.42mg/g after 15 days of exposure, while the lowest recorded concentration was presented after 20 days of test with 1.57 mg/g. For fluoranthene the initial concentration in organisms, when starting the trial was 5.88 mg/g and after exposure to the compound in the middle of the concentrations levels between 194.77mg/g for 5 days of testing and 1011.30mg/g for day 25 were registered. Fluctuations in terms of accumulation and purification of the compounds show a greater stability and incorporation of fluoranthene compared to naphthalene, which is related to the properties of each compound, especially those related to molecular weight and hydrophobicity.

Keywords : Bioaccumulation; polycyclic aromatic hydrocarbons; naphthalene; fluoranthene; Anadara tuberculosa.
