propiconazole: Survival data set for Gammarus pulex exposed to propiconazole during four days

Description

Survival data set of chronic laboratory toxicity tests with Gammarus pulex freshwater invertebrate exposed to eight concentrations of one fungicide (propiconazole) during four days. Eight concentrations were tested with two replicates of 10 organisms per concentration. Survival is monitored at five time points.

Usage

data(propiconazole)

Arguments

Format

A dataframe with 75 observations on the following four variables:

replicate

A vector of class factor with the replicate code (SC for the control and A1 to G2 for other profiles).

conc

A vector of class numeric with propiconazole concentrations in \(\mu mol.L^{-1}\).

time

A vector of class integer with the time points (in days from the beginning of the experiment \(t = 0\)).

Nsurv

A vector of class integer with the number of alive individuals at each time point for each concentration and each replicate.
