Datasets on aerobic soil metabolism of 2,4,5-T in six soils
Time course of 2,4,5-trichlorophenoxyacetic acid, and the corresponding 2,4,5-trichlorophenol and 2,4,5-trichloroanisole as recovered in diethylether extracts.
A dataframe containing the following variables.
the name of the compound observed. Note that T245 is used as an acronym for 2,4,5-T. T245 is a legitimate object name in R, which is necessary for specifying models using
a numeric vector containing sampling times in days after treatment
a numeric vector containing concentrations in percent of applied radioactivity
a factor containing the name of the soil
