Rock salmon

Mutagenic activity is also present in broiled herring, mackerel and sardine (11,12,22). In part, these mutagens were later identified as Trp-P-1 and Trp-P-2 (12) and IQ and 2-amino-3,4-dimethylimidazo [4,5-fJquinoline (Me-IQ)(13). In addition, Bjeldanes e t a. (23) have also reported mutagen formation in pan-fried fish, such as rock cod, sole, halibut, trout, salmon and red snapper. However, the mutagenic activity is low compared to that in beef. 

Cabell and Smales (IS) have described the application of neutron activation to the determination of rubidium and caesium in international standard rocks, lepidolites, samples from the Skaergaard Intrusion of East Greenland, and some stony meteorites. Smales and Salmon 9S) had previously determined the same two elements in sea water after a preliminary concentration on an ion exchange resin, and directly in other materials of geochemical interest. 

As a result, fishery in the Baltic has certainly a tradition, reaching back to the times of colonization by the first settlers at the Ancylus-lake or even further. As a matter of fact, excavated remainders, rock carvings and paintings indicate the catch of herring, salmon. 

The griddle-fried and the oven-broiled sanples of rcx k cod showed moderate mutagenic activity (1,300-2,000 revertants/100 gE) (Table 3). Xhe more extensively fried trout, salmon, and red snapper yielded 2,500-3,100 revertants/100 gE, Ahile halibut yielded about 1,100 revertants/100 gE. The remainder of the rock cod sanples, and the sole, shrinp, cind batter-fried seafood fran a commercial galley exhibited negligible or small amounts of mutagenic activity. These results are corparable to results of Krone and Iwaoka (j ). 

However, Mortimer (1981) and Findlay et al. (1984) who also worked in the area did not agree with the stratigraphic sequence proposed by Blank et al. (1963). Mortimer (1981) concluded that the Salmon and Miers Marble were the same layer of rock and that the Garwood Lake and the Marshall Formation were also the same unit. Findlay et al. (1984) who remapped basement rocks throughout southern Victoria Land subdivided the Koettlitz Group into the Marshall Formation, the Salmon Marble, and the Hobbs Formation but did not place them in stratigraphic order.

Evidence for the existence of a natural source of tetraalkyllead compounds comes from analysis of air from the open sea, from coastal, and from estuarine areas, since 1 to 30 ng/m tetraalkyllead was observed [61] further evidence was found from abnormally high alkyllead to total lead ratios, which have been observed in atmospheric samples in Morecambe Bay, U.K. [60]. It was speculated that these tetraalkyllead emissions arise from methylation of lead compounds in coastal and estuarine intertidal areas [61]. The hypothesis of a natural source was supported by additional measurements [132, 174] see also [46, 133, 134]. However, according to recent results on transformation rates and lifetime of alkyllead species in the atmosphere it is not necessary to invoke the hypothesis of the natural alkylation of lead to explain the enhanced alkyllead to total lead ratios [182]. Also no indication of a large-scale natural source for tetraalkyllead compounds was found in other work [22], and determination of atmospheric content of tetraalkyllead compounds gave no indication for the occurrence of natural methylation processes of lead(ll) compounds [23] see also [48, 69, 70, 73]. The origin of trialkyllead species in rural pigeons (Columba livia) was associated in part with natural sources of tetraalkyllead in the environment [135], and also the presence of small amounts of Pb(CH3)4 in fish (Coho Salmon, Yellow Perch, Sucker, Rock Bass, Sunfish) from various lakes and rivers in Ontario, Canada, was taken as an indication for the possibility of environmental methylation or in vivo methylation of lead in fish [95] see also [93]. It was considered conceivable that bacteria in fish intestines or in fish tissue could methylate lead compounds [93, 94, 101, 178].
