PCDD, PCDF, PCB and thiamine in Baltic herring (Clupea harengus L.) and sprat [Sprattus sprattus (L.)] as a background to the M74 syndrome of Baltic salmon (Salmo salar L.)
Baltic herring and sprat were sampled between October 1994 and January 1995 off the southern coast of Finland and around the Åland Islands. From this material fish of 135–159 mm in length, a size class that was assumed to be preferred as prey by Baltic salmon, were selected and grouped according to...

Baltic herring and sprat were sampled between October 1994 and January 1995 off the southern coast of Finland and around the Åland Islands. From this material fish of 135–159 mm in length, a size class that was assumed to be preferred as prey by Baltic salmon, were selected and grouped according to species, sex and age. Herring were 1–3 years and sprat 3–13 years old. In addition, one group of smaller, two-year-old, female sprat was selected. Thus twenty groups were formed and prepared as whole-fish homogenates. Thiamine was quantified from all homogenates, while female and male sprat and female herring were analysed for polychlorinated biphenyls (PCBs), dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs). There were no significant differences between sexes within each species in the total thiamine concentrations, but the mean total thiamine concentration in 1 to 3-year-old herring (8.6 nmol g−1) was higher than that in 2 to 13-year-old sprat (6.7 nmol g−1).
