In bioassay experimentations, for instance tests on insects, to evaluate the efficacy of a chemical product, we have usually two important parameters: toxicity and mortality tests. But I'm wondering if there is a difference between the meaning of toxicity and mortality tests or is the same?
Dear Billal,
In my opinion, which is personal, the toxicity test is where the product affects one or more organs; creating a partial or complete dysfunction.
On the other hand, mortality is the total cessation of organs.
That is, the mortality point is beyond the point of toxicity.
It remains a personal opinion.
Cordially.
Dear Bilal
A toxic substance affects the physiological function of individuals and how this toxin affects the demography (birth and death rates) of the population. Species react differently to toxic substances. You can study survival/mortality of a cohort after been exposed to toxic substance by means of Kaplan-Meier survival curves.
Hope this helps
