Green alga (Selenastrum capricornutum) was exposed to cadmium chloride concentrations ranging from 5 to 80 micro g/L in geometric progression in 4-day population growth test.
A data frame with 18 observations on the following 3 variables.
conc
a numeric vector of cadmium chloride concentrations (micro g/L)
count
a numeric vector of algal counts (10000 x cells /ml)
Details
The data are analysed in Bruce and Versteeg (1992) using a log-normal dose-response model (using the logarithm with base 10).
