Fig. 3From: Meso- and microplastic distribution and spatial connections to metal contaminations in highly cultivated and urbanised floodplain soilscapes – a case study from the Nidda River (Germany)Contaminants along the river course indicated with river length (km) and grouped according to floodplain positions (proximal, central, distal). a Plastic abundance (p kg− 1) at each sampling point (n = 10) and not significant (ns, p > 0.05) differences between sites; b PLI at each sampling point (n = 10) and not significant (ns, p > 0.05) differences between sitesBack to article page
