Publications testing the effects of surfactants on Folsomia sp. using (a) flotation or (b) heat extraction in a 28-day reproduction test. LAS = linear alkyl benzene sulfonic acid; OECD = artificial Organisation for Economic Co-operation and Development soil (OECD 2016). If other endpoints were tested as well, any comparisons refer to F. candida or F. fimetaria, respectively.
