Table 1.

Mortality and hatching success of killifish embryos from New Bedford Harbor (NBH) and Scorton Creek (SC) following an acute exposure to tBHQ at different days post fertilization (dpf). For each day, 200 embryos per population were exposed, with 50 embryos per tBHQ concentration. For each concentration, there were 5 pools of 10 embryos. Percentages are cumulative within a concentration
