AGE AND SIZE-DEPENDENT CHLORINATED-HYDROCARBON CONCENTRATIONS IN MARINE TELEOSTS

Age and length dependent concentrations of chlorinated hydrocarbons in several Baltic and North Sea fish have been determined. Over a range of 15 years chlorinated hydrocarbons have been determined in ovary and muscle of herring, flounder, dab, whiting and horse mackerel. It is c oncluded, that generally no increase in accumulation occurs with age o r size. The release of eggs, and to a certain extent also the sperm, h as a purging effect that prevents excessive accumulation in potentiall y sensitive compartments of the fish body.
