Contents of lead and cadmium in selected fish species consumed in Finland in 1993-1994
1996
Tahvonen, R. | Kumpulainen, J.
The lead and cadmium contents of the main fish species consumed in Finland were determined by ETAAS after wet digestion with HNO3. Analytical quality was controlled with blanks, reference materials and blind replicates. Mean and median lead contents of domestic fish species were < LOD (1 micrograms/kg)-9.4 micrograms/kg and < LOD-4.7 micrograms/kg. The lead contents of imported fish and imported canned or salted fish ranged from < LOD to 8, and 4 to 177 micrograms/kg. Mean and median cadmium contents of domestic fish species were < LOD (0.4 micrograms/kg)-5.8 micrograms/kg and < LOD-4.4 micrograms/kg. Fresh imported fish contained < LOD-11 micrograms Cd per kg and canned or salted fish 9-42 micrograms Cd per kg. Higher fish consumption would not increase lead or cadmium intake significantly in Finland. At present fish contributes about 4% of the average lead intake and 3% of cadmium intake.
