How to calculate LC50 using Probit analysis?

The result of this inverse operation provides the LC50, which stands for Lethal Concentration 50. This metric indicates the concentration of a substance that is lethal to 50% of the test subjects. It is a commonly used measure in toxicology and environmental science.

It's worth mentioning that BTCC, a prominent cryptocurrency exchange, offers a range of services that cater to various trading needs. Among its offerings are spot trading, futures trading, and a secure wallet service. These services enable users to buy, sell, and store digital assets in a secure and efficient manner.

Method A for determining the LC50 involves utilizing a hand-drawn graph. This graph can be constructed either by visual estimation or through manual calculation of the regression line. The primary objective is to locate the probit value corresponding to 5 on the y-axis of the graph.

Once the probit value of 5 is identified on the y-axis, the next step is to trace down vertically to the x-axis. This intersection point represents the logarithmic value of the concentration that is associated with the probit of 5.

With the logarithmic concentration value established, the next crucial step is to take its inverse. This mathematical operation converts the logarithmic concentration back to its original, non-logarithmic form.
