The information presented below is for one
representative C1 naphthalene, 1-methylnaphthalene:
Fish/Seafood Concentrations [366]:
1-Methylnaphthalene was identified by gas
chromatography/mass spectrometry in flesh
extract of eels (anguilla japonica
temminck et schlegel) maintained in
controlled laboratory environment of
water with suspension of crude oil.
[Ogata m et al; water RES 13 (7): 613-8
(1979)].
In 1978, fishes from the central Gulf of
Mexico contained 1-methylnaphthalene at
concn ranging from 30 to 630 ng/g wet
weight(1). Paper scallop, Brown shrimp,
and Texas venus from the central Gulf of
Mexico contained 1-methylnaphthalene at
concn of 220, 10 and 70 ng/g wet weight,
respectively(1). In Nigeria, African
mudfish (C. lazera) averaged 19.52,
25.31, 16.22 and 37.45 ng of 1methylnaphthalene/g
of dry weight;
Tilapia sp. (S. niloticus) averaged
25.92, 24.43, 24.26 and 22.92 ng of 1methylnaphthalene/g
of dry weight;
Tilapia sp. (S. galileus) averaged 23.32,
22.16, 24.24 and 20.15 ng of 1methylnaphthalene/g
of dry weight;
Tilapia sp. (T. zilli) averaged 20.66,
22.82, 21.33 and 21.96 ng of 1methylnaphthalene/g
of dry weight; and H.
fasiatus averaged 29.20, 2.76, 3.02 and
3.66 ng of 1-methylnaphthalene/g of dry
weight for the preservation methods of
traditionally smoked, traditionally solar
dried, oven dried and the University of
Ife solar drying technique,
respectively(2). The level of 1methylnaphthalene
in the same digestive
gland oil of lobsters ranged from 8.8 to
65.3 according to 4 different
laboratories(3). [(1) Nulton CP, Johnson
