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. WebIncipient means something is in an early stage of existence. In its incipient form, basketball was played with a soccer ball and peach baskets for goals. Bouncy orange balls and nets …

WebThese tests have established lethal values for coho known as critical thermal maxima (CTM) and upper incipient lethal temperatures (UILT). It has not been established how these values relate to fish stress and mortality in nature. Fish in the wild must forage for food and avoid predation, while in laboratory environments the fish are fed and ... For gases and aerosols, lethal concentration (given in mg/m or ppm, parts per million) is the analogous concept, although this also depends on the duration of exposure, which has to be included in the definition. The term incipient lethal level is used to describe a LC50 value that is independent of time.
