Effect of exposure to NB-labeled PS-MPs beads on the plant height, shoot and root biomass of S. nigrum

Plant heights were 15.6 cm and 15.0 cm after treatment with 0 and 0.2 µm MPs, respectively. The presence of PS beads had no significant effect on plant height and root and shoot biomass of S. nigrum seedlings after exposure to PS beads for 30 d.
