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 2020 from 12 lakes.

Pooled liver samples (muscle tissue for mercury analyses) were analyzed for organic chemicals, isotopes and metals. Trout (Salmo trutta was the preferred species, but in two lakes char (Salvelinus alpinus) or perch (Perca fluvialis) were the available species.
