LD50arviot
LD50arviot is a term used in toxicology to describe estimated LD50 values—the dose of a substance expected to kill 50% of a defined test population. The word arviot signals estimation, and the phrase is encountered in Finnish-language resources and in multilingual datasets that summarize lethal-dose information. LD50arviot are commonly reported for standard exposure routes such as oral, dermal, and inhalation, and are typically expressed in milligrams of substance per kilogram of body weight (mg/kg).
Estimates arise from two sources: direct LD50 measurements reported in the toxicology literature and statistical models
LD50arviot are used in hazard classification, regulatory risk assessment, and safety documentation such as product labels
Limitations include substantial interspecies and intra-study variability, dependency on route of exposure, formulation, age and sex
