EU Water Framework-Directive Priority Contaminants in Norwegian Freshwater Fish: 2021
Om publikasjonen
Priority substances under EU water framework directive, and other substances of concern, were analyzed in fish liver sampled from 12 Norwegian lakes.
Fish were sampled by the Norwegian Institute for Nature Research (NINA) as part of an assignment for ecosystem monitoring. In the present report, the environmental monitoring program included fish caught during summer and autumn 2021 from 12 lakes.
Pooled muscle samples were analyzed for organic chemicals, isotopes and mercury. Other metals than Hg were analysed in kidney samples, and PFAS was analysed in liver samples. Trout (Salmo trutta) was the preferred species, but in one lake char (Salvelinus alpinus), and in 3 lakes perch (Perca fluvialis) were the available species.
