referenssitasoarvon

Referenssitasoarvo is a numeric value used as a standard or benchmark for interpreting measurements and assessing risk or quality. It functions as a reference point against which observed concentrations, doses, or exposures are compared. The value itself is not a direct measurement but a guidance level that helps determine whether action is required.

In environmental health, occupational safety, toxicology, and food and consumer safety, referenssitasoarvo can take different forms depending on context. It may be expressed as a concentration (for example, in air or water) or as a dose or exposure level (such as a daily intake). These values are typically derived from toxicological reference values, such as NOAEL or LOAEL, benchmark dose estimates, or reference doses, and are adjusted with uncertainty and safety factors to cover variability among populations.

Application involves comparing measured results to the referenssitasoarvo. If a value exceeds the reference threshold, authorities may initiate follow-up actions, increased monitoring, or risk-reduction measures. If the value remains below the threshold, the result is generally considered acceptable within the defined context and exposure scenario.

In Finland, referenssitasoarvoja are used in risk assessments and monitoring programs across environmental and public health contexts. They help interpret results from air and water quality monitoring, food safety evaluations, and consumer product testing. The concept is closely related to other terms such as threshold values and guideline values, but is specifically employed as a health- or safety-based reference point for decision-making.
