lw (lipid weight), were also found (Table
7). The ortho,para isomers were not de-
tectable at approximately 2 pg/kg lw or
were found in concentrations very close to
this detection limit.
The concentrations of the DDTs in
white-sided dolphins are given in Table 9
and those in the pilot whales in Table 10.
The larger part of the Sum DDT2 concen-
tration consists of p,p’-DDE, and this is to
be expected based on the above-mentioned
reasons. The concentrations vs. body
length are given for white-sided dolphins
and pilot whales in Fig. 11 and Fig. 12, re-
spectively. What is really remarkable is the
comparatively high concentration of o,p’-
DDT, which is present in a small percent-
age only in the original technical pesticide
formulation (WHO, 1979). In pilot whales
and white-sided dolphins, the concentra-
tion of o,p’- DDT is approximately equal to
that of p,p’-DDT. In absolute values, the
