## Algae Growth Inhibition Data Set

### Description

A dose-response experiment was conducted using Atrazine at 9 different dose-levels including the zero-dose control and the biomass of algae (Selenastrum capricornutum) as the response variable. Three replicates were measured at day 0, 1 and 2. The fluorescence method (Mayer et al. 1997) was applied to measure biomass.

### Format

A data frame with 22 observations on the following 10 variables.

concentration

  a numeric vector of dose value in mg / L

Day.0

  a numeric vector, total biomass

Day.0.1

  a numeric vector, total biomass

Day.0.2

  a numeric vector, total biomass

Day.1

  a numeric vector, total biomass

Day.1.1

  a numeric vector, total biomass

Day.1.2

  a numeric vector, total biomass

Day.2

  a numeric vector, total biomass

Day.2.1

  a numeric vector, total biomass

Day.2.2

  a numeric vector, total biomass
