Disse maalsaetninger fastsaettes isaer paa grundlag af de paagaeldende stoffers toksicitet , persistens og bioakkumulation i levende organismer og i aflejringer , saaledes som disse fremgaar af de seneste , efterproevede videnskabelige oplysninger under hensyn til forskellene i havvands - og ferskvands karakteristisk .
These objectives shall be laid down principally on the basis of the toxicity, persistence and accumulation of the said substances in living organisms and in sediment, as indicated by the latest conclusive scientific data, taking into account the difference in characteristics between salt-water and fresh water.
