A median mortality of 120 ± 30 days occurred among juvenile Atlantic salmon (Salmo salar), fed dry fish food containing 2.7, 5.7, 2.8, and 9.1 uMg/g wet weight of 2,8di-, tri-, tetra-, and octachlorodibenzofuran, respectively (1). Only octachlorodibenzofuranx was detected in the dead fish, and the level was 0.03 ug/g in the muscle and 0.21 ,Ag/g in the gut (both values on wet weight basis). The...
