Total arsenic and water-soluble arsenic species were determined in canned fish bought in Graz (n = 6) and Prague (n = 8) with inductively-coupled plasma mass spectrometry and anion-exchange liquid chromatography. A difference in total arsenic content between samples from Prague (mean 3.4; standard deviation (s.d.) 1.2 mg kg–1) and Graz (mean 2.5; s.d. 0.7 mg kg–1) was not significant, however Prague samples differed in abundance of arsenobetaine (mean 83% of extractable arsenic; s.d. 16%) vs. Graz samples (mean 66%; s.d. 10%). No differences in total arsenic were caused by fish species (mackerel, sardine, herring, tuna) and origin (Northeast and Eastern-central Atlantic).
