Fig. 65 a,b. DDT is stored up in different quantities in the various organs of a fish. The diagram
show the result of experiments with sole (Solea solea) which had been fed 17 p.g of radioactively
marked DDT. The DDT concentrations (on wet weight basis) in the various organs are indicated
in a. The absolute DDT amounts in fish that were analyzed after being fed DDT for 3 days are
indicated in the white bars of b. The black bars indicate how much DDT was still in tissues after
the fish were kept in a DDT·free environment for 2 months and were able to eliminate DDT into
the aquarium water. The figures indicate the percentage of DDT that was not eliminated in this
period (Ernst and Goerke 1974)

Solea solea
Fig. 66. Even in one and the
same marine locality different
organisms have different pat·
terns of chlorinated hydrocarbons (per wet weight) in
tissues. Different sources of
food and different metabolic
pathways are reflected. The
graph shows patterns for cockle,
lugworm, shrimp, clam, and
sole from a subtidal area in
the Weser Estuary, North Sea,
several miles away from the
coast and away from the main
shipping route, and not by a
point source polluted. PCB's
are represented by figures, the
other compounds by bars
with the meaning: A DOD,
B dieldrin, C alpha-HCH,
D lindan, E DOE, F alphaendosulfan (Goerke et al.1979)
