WebThe term incipient lethal level is used to describe a LC 50 value that is independent of time. [8] A comparable measurement is LCt 50, which relates to lethal dosage from exposure, where C is concentration and t is time. It is often expressed in terms of mg-min/m 3. LCt 50 is the dose that will cause incapacitation rather than death. WebMay 5, 2024 · Incipient lethal values were determined as well. In general, surprisingly lower lethal concentrations were found than in other studies. Furthermore, the present study shows that lethal concentrations based on free ion activities were generally much lower than nominal and effective concentrations. fishing rods on sale near me
