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. how much are olivia rodrigo ticketsWebMar 21, 2024 · 这 种起始致死温度的下限值称为低起始致死温度（Lower Incipient Lethal Temperature，LILT 50 ），而上限值则称为高起始致死温度（Upper Incipient Lethal Temperature，UILT 50 ）（Brett，1956）。 研究表明，不同种鱼类的致死温度、临界温度和热适应能力是不同的（Brett， 1952；Otto ... how much are old vinyl albums worthWebMeaningful minimum levels of 02 concentration at which fish can live are not easily determined.
