Data for effects resulting from exposure to dioxin, and observed survival and fecundity by age and size for unexposed populations
These laboratory data for estimates of change in fertility and survival rates observed relative to control (unexposed) conditions for fundulus heteroclitus exposed to varying levels of 2,3,7,8-tetrachlorodibenzo-p-dioxin including 112, 296, and 875 pg/g are relative rates, and thus they are unitless.
