Flagfish Jordanella floridae were exposed to 4 vanadium concentrations up to 96 days; 0.041, 0.17, 0.48 and 1.5 mg/L under flowthrough conditions. Mortality, size, reproduction and abnormalities were assessed, for 2 generations.
The first 0.041 mg/L concentration was found to increase the average dry weights of all generations of flagfish. The NOEC for weight of first generation was defined to be 0.48 mg/L, and 0.17 mg/L for mortality.
The reproductive performances were not affected by exposure to vanadium.
The only deleterious effect was a decrease in dry weight of second generation larvae, from 0.17 mg/L. The authors considered that the sublethal treshold for toxicity of vanadium would approximate the geometric average of 0.17 and 0.041 mg/L, which is 0.08 mg/L.
