Percent mortality for mixture experiments assessed every 24 h from 1–120 h post fertilization (hpf). Mixture experiments in which Pb was held constant at the 120 hpf-LC₂₅ (39.0 ppm) in experiment 1 (A) and in which Pb was held constant at the 120 hpf-LC₅₀ (73.76 ppm) in experiment 2 (B), while As was varied to include the 120 hpf-LC₂₅, 120 hpf-LC₅₀, and 120 hpf-LC₇₅. N = 3 biological replicates for each treatment group with 50 subsamples per each treatment group. Data is presented as mean ± standard deviation. * p < 0.05.
