AB  - Plants play a fundamental role in maintaining coastal dunes but also accumulate 
      littered microplastics (MPs). Migration tests suggest that naturally weathered 
      MPs can leach out a broader range of potentially phytotoxic chemicals than virgin 
      MPs. Thus, assessing MPs effects on plants using beached-collected particles 
      rather than virgin ones is critically important. Here, the effects on plants of 
      leachates from two pools of beach-collected and virgin MPs, high-density 
      polyethylene (HDPE) and polypropylene (PP), and their mixture, were explored 
      combining toxicity tests and chemical analyses. Phytotoxicity of MP leachates at 
      different dilutions was evaluated under standard laboratory conditions using test 
      species and under environmentally realistic conditions using the dune species 
      Thinopyrum junceum. Leachates from beached PP and HDPE adversely affected all 
      species, and the extent of these effects varied according to polymer type, 
      concentration, and species. Virgin MPs had weaker effects than beached ones. 
      Several potentially phytotoxic oxidized compounds were detected in water by GC/MS 
      analysis, and their amount estimated. Results indicate that the molecular species 
      leaching from beached MPs - at ppm concentration levels for the individual 
      chemical species - can inhibit plant growth, and the effects of leachates from 
      mixtures of degraded MPs can differ from those from individual polymers, 
      highlighting the need for further investigation of MPs consequences for coastal 
      ecosystems.
