Effects of residues of the polychlorinated biphenyl Aroclor 1254 on the sensitivity of rainbow trout to selected environmental contaminants

Journal Article · · Prog. Fish-Cult.; (United States)

Rainbow Trout were exposed to two concentrations of the polychlorinated biphenyl, Arachlor 1254: 0.1- and 0.01 ..mu..g/l. Gas-liquid chromatography of the homogenized whole trout revealed average amounts of 0.46 ..mu..g/g at low-level exposure and 3.40 ..mu..g/g at high-level exposure. Sublots of each group were then exposed to the following contaminants in standardized acute toxicity tests: nitrate, nitrite, cyanide, chlorine, mercury, and chromium. The toxicity of cyanide was increased significantly by both concentrations of Arachlor 1254; the toxicity of chromium was increased only by the high concentration. The toxicities of nitrate nitrogen, nitrite nitrogen, chlorine, and mercury were unaffected by previous exposure to either concentration of the polychlorinated biphenyl.
