multiple_stress

A data set of mixture toxicity experiments. Individuals of Daphnia magna were
exposed to combinations of food stress and multiple concentrations of the
pesticides esfenvalerate and prochloraz. The survival was recorded at 21 days
after contamination.

The stress addition approach is an alternative to the traditional
concentration addition or effect addition models. It allows the modelling
of tri-phasic concentration-response relationships either as single toxicant
experiments, in combination with an environmental stressor or as mixtures of
two toxicants. See Liess et al. (2019) <doi:10.1038/s41598-019-51645-4>
and Liess et al. (2020) <doi:10.1186/s12302-020-00394-7>.
