Fig. 5

Concentrations of selected MPs in different environmental compartments. Concentrations are shown as box-whisker plots with values below LOQ imputed by means of ROS under assumption of a lognormal distribution. If more than 80% of observations were below LOQ, no boxplot is shown. Notches in the boxes indicate roughly 95% confidence interval for comparing medians. The range of the LOQ is indicated by red dashed box. The number of observations (N) is shown as annotation above or below the boxes. The numbers underlaying this figure can be found in Additional file 1
