Table 5. Bioaccumulation factor of PAHs in body tissues, fecal pellets and eggs of the copepod Acartia tonsa exposed to crude oil (5 µl L−1, 48 h, artificial light) with two different food regimes:
Type of food | A.tonsa sample | Phe | Flua | Pyr | Chr | BbF |
Rhodomonas sp. | body tissues | 66 | 1023 | 190 | 68 | n.d. |
fecal pellets | – | – | 670 | 1471 | 5276 | |
eggs | – | 902 | – | 48 | n.d. | |
Oxyrrhis marina Rhodomonas sp. | body tissues | 4 | – | – | 27 | n.d. |
fecal pellets | – | – | – | 992 | 288 | |
eggs | 102 | 874 | – | 90 | n.d. |
(1) Rhodomonas sp. and (2) Rhodomonas sp plus Oxyrrhis marina. Phenanthrene (Phe), fluoranthene (Flua), pyrene (Pyr), chrysene (Chr), benzo[b]fluoranthene (BbF). Dash indicates no bioaccumulation (concentration in experimental treatment was similar or lower than in respective control treatment). n.d. = no detected.
