Figure 4From: High throughput nano-liter RT-qPCR to classify soil contamination using a soil arthropodRelative expression levels of cadmium (a) and phenanthrene (b) markers in cadmium and phenanthrene treated Folsomia candida. Significance levels between control and cadmium/phenanthrene: * p < 0.05; ** p < 0.01; *** p < 0.001 (one-way ANOVA; Bonferroni post-hoc test).
