Dose-Response curve

Definition

A dose-response curve illustrates the relationship between the dosage or concentration of a substance and its effect on an organism, population, or ecosystem. It helps determine the toxicity level and potential risks associated with different exposure levels.

LD50 (Lethal Dose 50%): LD50 represents the dosage required to cause death in 50% of exposed individuals or organisms within a specified time frame. It is commonly used to measure acute toxicity.

Threshold Level: The threshold level refers to the lowest dose or concentration at which an adverse effect begins to occur. Below this level, there may be no observable impact on organisms.

Synergistic Effects: Synergistic effects occur when two or more substances interact in such a way that their combined effect is greater than the sum of their individual effects. This can result in increased toxicity and impacts on organisms or ecosystems.
