“…This might indicate that there is no obvious variation in the pattern of the PCB congeners studied in different parts of Gulf of Finland. Our herring data from the Gulf of Finland in 1991 show lower PCB and DDT levels than in the samples collected by Haahti andPertilla in 1986 (Haahti, Perttila, 1988).…”

“…This was due to the widespread application of DDT in forestry in one of the Baltic states (in 1983-1985). Since then, the concentrations of DDT have returned to their previous levels (Haahti, Perttila 1988).…”

“…By the literature (Haahti, Perttila 1988) in 1986, the DDT concentrations in the herring muscle ranged from 0.3 mg/kg in the Bothnian Bay to 0.7 mg/kg in the Gulf of Finland (in extractable fat). The lowest PCB values are found also in the Bothnian Bay (1.1 mg/kg in extractable fat), and the highest concentrations are in western part of the Gulf of Finland and Bothnian Sea (2.2-2.5 mg/kg) in extractable fat).…”

This report is a part of studies on toxic substances in the Baltic fish.A study of persistent chlorinated hydrocarbons in the Baltic herring and sprat muscle tissue was carried out in the Eastern Baltic in 1975Baltic in -1977Baltic in , 1986Baltic in and 1991 In 1991 organochlorine compounds (such as polychlorinated biphenyls (PCB), DDT and its metabolites DDE and DDD, hexachlorocyclohexane isomers (HCH), hexachlorobenze (HCB) and others) were determined by high-resolution capillary gas chromatography with electron capture detection.

“…For herring from the Gulf of Riga Roots (1996a reports however a lower mean value of total DDT -0.28 mg/kg extractable fatand therefore he states that the Gulf of Riga is a high class reference area due to the low concentrations found there compared with the concentrations found elsewhere along and off the Estonian coast. This finding and the values of total DDT for herring from the Gulf of Bothnia and the Finnish part of the Gulf of Finland of 0.3-0.7 mg/kg extractable fat (Haahti & Perttild, 1988) make the values for herring from the Viike Viin Strait intermediate to those for herring from the open sea and the inner parts of the Baltic Sea. Miettinen et al (1985) however recorded considerably higher concentrations of total DDT in both herring (1.6 mg/kg extractable fat) and pike (2.9 mg/kg extractable fat) from the coastal waters of the Gulf of Finland reflecting the pollution situation of the waters at the time of sampling in 1978.…”

Heavy metals (Hg, Fe, Mn, Zn, Cu, Cd, Pb, Ni) and organochlorine compounds (HCHs, HCB, DDTs, PCBs) were analysed from muscle tissue and livers of Baltic herring (Clupea harengus membras L.), sprat (Sprattus sprattus balticus L.), smelt (Osmerus eperlanus L.), pike (Esox lucius L.), bleak (Alburnus alburnus L.), roach (Rutilus rutilus L.), ruffe (Gymnocephalus cernua L.), perch (Perca fluviatilis L.), and garpike (Belone belone L.) from the Viike Viin Strait during high summers of 1993-94. Mercury concentrations were higher in the muscle tissue than liver for both smelt and perch. For perch both these concentrations were higher than they were for smelt. In the muscle tissue of all predatory fishes (pike, perch, ruffe, garpike) the concentrations of mercury were higher than for the nonpredatory species (herring, sprat, smelt, bleak, roach). The concentrations of mercury were higher in the coastal inshore species (pike, perch, roach, smelt) than in open-sea fishes (garpike, herring, sprat). For metals other than mercury the values of manganese tended to be higher in smelt than in the two clupeids but for copper the opposite was observed.For cadmium and nickel the values measured for sprat, smelt, and bleak tended to be higher than they were from the same species from comparable Finnish coastal waters. The same is true for lead from herring, smelt, and bleak. For iron and zinc no such differences were observed. For both the organochlorine pesticides and PCBs, the concentrations were higher in the homogenates of migrating pelagic partly open-sea species (herring, sprat, garpike) than in the homogenates of less migrating coastal species (smelt, pike, perch). The food safety levels in Estonia or Finland for either metals or organochlorine compounds were exceeded in no cases.

“…Levels of DDT and PCB have been determined in liver from immature cod species (Gadus morhua) and in herring (Clupea larengus) muscle [20]. DDT levels in herring muscle between 1979 and 1986 were 0.3 { 2.2 mg/kg, but dropped to 0.010 { 0.017 mg/kg in 1988.…”
