Accumulated expression levels of cadmium and phenanthrene markers in cadmium and phenanthrene treated Folsomia candida. Accumulated average expression level over all markers was upregulated relative to the control for cadmium as well as for phenanthrene (Kruskal-Wallis, χ2 (2) = 40.97, p < 0.0001, followed by Dunn's multiple comparison test). Phenanthrene markers showed higher accumulated expression levels in phenanthrene than cadmium treated samples (paired t test, t (19) = 4.066, p < 0.0001), for cadmium markers no difference between cadmium and phenanthrene samples was detected (paired t test, t (23) = 1.168, p = 0.2). White box = controls; dashed box = cadmium treatment, grey box = phenanthrene treatment.
