minnow_it: A fitted GUTS-RED-IT scenario of the fathead minnow

Description

The example scenario consists of a fitted GUTS-RED-IT model and a constant exposure series. Model parameters were derived from a typical four-day acute fish toxicity study of the fathead minnow by Geiger et al. (1988). The study evaluated the effect of chlorpyrifos concentrations in water on survival of fathead minnows.

Usage

minnow_it

Format

An object of class GutsRedIt of length 1.

Details

The toxicity dataset used for parameter calibration is also referred to as GUTS Ring-test dataset C by EFSA (2018). Fitted parameters were estimated using the morse package.

The exposure series of the example scenario is a constant concentration of 1.0 µmol/L over a period of four days with a daily time step.
