Oedogonium cardiacum

Unknown Fish exposed to radiolabeled diflubenzuron for33 days contained about 6% of the parent diflubenzuron vs. 54% for alga (Oedogonium cardiacum), 82% for snail (Physa sp.), and 94% for larvae of mosquito (Culex pipiens quinquefasciatus) 42...

Oedogonium cardiacum exposed to hexachlorobenzene for 33 days (Isensee etaL, 1976). Invertebrate species similarly sorb monocyclic compounds directly from the water, but food may also be a primary route of entry, particularly for the less soluble derivatives such as hexachlorobenzene. Isensee et al, (1976) reported that exposure of gastropods and cladocerans to this latter compound resulted in concentration factors of 910 to 1500, whereas the corresponding values for grass shrimp Palaemonetes pugio and pink shrimp Penaeus duorarum were 2000 to 4100.
