A Laboratory and field Comparison of Sediment Polycyclic Aromatic Hydrocarbon Bioaccumulation by the Cosmopolitan Estuarine Polychaete Streblopspio benedicti (Webster)

摘要

Polycyclic aromatic hydrocarbon (PAH) bioaccumulation by the polychaete worm Streblospio benedicti (Webster) was measured under exposure to PAH- contaminated sediments in the field and for 28 d in the laboratory. Streblospio benedicti collected from field sediments contaminated at 2.94, 1.07, and 1.52 ugg~-1 fluoranthene (FLU), benz[a]anthracene (BAA), and benzo[a]pyrene (BAP), bioaccumulated those PAHs at 1.53, 0.215, and 0.332 ugg~-1, while worms iso- lated from less contaminated field sediments (0.399, 0.228, 0.288 ugg~-1 FLU, BAA, and BAP) had FLU, BA, and BAP body burdens of 0.543, 0.236, and 0.083 ugg~-1.
