Metals in biota

Updated 2011-01-19

National Environmental Monitoring in Sweden. Monitoring of heavy metals in fish proceeds in 110 trend lakes in entire Sweden (12 lakes are in AMAP area). Annual sampling is carried on 32 lakes,which seven are in AMAP area. Three fish species are selected: Arctic char (Salvelinus alpinus), Northern pike (Esox lucius), and Perch (Perca fluviatilis). In prepared samples of muscles and liver selected metals are analysed. Analyzed metals in liver are : Al, Ag, As, Bi, Cd, Cr, Cu, Ni, Pb, Sb, Sn and Zn. In muscle samples Hg and stabile isotopes δ 15N, δ 13C are analysed.

This is a National Implementation Plan (NIP) project
Comments and additional information:

Fish samples are collected and stored in the Environmental Specimen Bank in Swedish Museum of Natural History NRM). The Swedish Board of Fisheries monitors and determine the Sweden's fish resources in small and middle-large lakes, human impact, a years variation of sampled fish populations, and a bank sampling of fish.
