metsulfuron {lemna}

A Lemna scenario fitted to metsulfuron-methyl effect data

Description

The dataset consists of a named list which contains vectors describing initial state, parameters, output times, and environmental variables of the Lemna model.

Usage

metsulfuron

Format

An object of class lemna_scenario of length 4.

Details

The scenario will simulate a period of 14 days with daily outputs, a start population of 12 fronds, unlimited growth conditions, and an exposure pattern represented by a step-function.

The scenario setup was published by Schmitt et al. (2013). A mechanistic combined toxicokinetic-toxicodynamic (TK/TD) and growth model for the aquatic macrophytes Lemna spp. was parameterized by the authors based on literature data. TK/TD parameters were determined by calibrating the model using substance specific effect data of metsulfuron-methyl.
