Table 1.

LC- and EC-values for the effects of 2-phenylethyl isothiocyanate on survival and reproduction, respectively of Folsomia candida and Protaphorura fimata after 28 days exposure in LUFA 2.2 soil. Values are in nmol ITC per gram soil (nominal concentrations)

	F. candida	CI	P. fimata	CI	χ²
LC10	10.4	(8.67–12.1)	9.32	(6.81–11.8)	0.44
LC50	15.4	(14.1–16.7)	15.2	(13.5–17.0)	0.03
EC10	6.29	(3.73–8.84)	6.08	(2.92–9.24)	0.01
EC50	12.0	(9.94–14.0)	11.2	(8.63–13.8)	0.18

CI = 95% confidence interval. Life history trait differences between F. candida and P. fimata are deemed significant (p < 0.05) if χ² > 3.84
