A Lemna_SETAC scenario with variable environment

Description

A mechanistic combined toxicokinetic-toxicodynamic (TK/TD) and growth model for the aquatic macrophytes Lemna spp. as published by Klein et al. (2021).

Usage

focusd1

Format

An object of class LemnaSetacScenario of length 1.

Details

The scenario will simulate a period of 365 days, a start population of 80 g/m² dry weight, variable environmental conditions, and a complex, time-varying exposure pattern.

The scenario setup was published by Hommen et al. (2015). Exposure pattern and substance specific parameters are of exemplary character and represent the herbicide metsulfuron-methyl. The parameters were derived by Schmitt et al. (2013) based on literature data.
