Bioacumulación de hidrocarburos aromáticos policíclicos en Anadara tuberculosa (Sowerby, 1833) (Arcoida: Arcidae)

Abstract

Three bioaccumulation tests were conducted. Bivalve mollusks of the species Anadara tuberculosa were exposed to naphthalene concentrations of 100,00 ppb. They were also exposed to fluoranthene (100,00 ppb) and a mixture of 16 polycyclic aromatic hydrocarbons (PAH); (15,48 ppb) which are considered priority pollutants by the Environmental Protection Agency (U.S. EPA). The minimum incorporation was recorded in organisms exposed to naphthalene (3,40 ppb), a level lower than in organisms exposed to the same concentration of fluoranthene and concentration of the mixture of PAH which reached 101,13 x 104 ppb and 4,80 ppb x 103 respectively.
