Title: Plastic chemical additive release from plastic debris and their mobility in soil agroecosystems

Duration: 2023 - 2027



The project, “Plastic chemical ADDItive release from PLAstic debris and their mobility in Soil agroecosystems”, AddiPlaS, will determine the PCA (Plastic Chemical Additives) release from microplastics (MPs), the fate of PCAs in soil and their impacts on soil health through simulated agroecosystem experiments under relevant environmental conditions and ad-hoc designed laboratory tests.

General activities

  • MP generation and methodologic development for PCA analyses
  • Assessment of PCA release in water
  • Simulated agroecosystem experiment in soil
  • PCA impacts on soil health: microbiota and plant development
  • Environmental field sampling

Expected impact

AddiPlaS will contribute to determine PCA release rates from MPs and will discriminate between effects of MPs and PCAs to shed a light about the role of PCA in the environmental risk associated to plastic contamination. AddiPlaS will advance in developing methodologies under ad-hoc designed experimental approaches for detecting PCAs in environmental matrices using cutting edge instrumentation and combining different analytical strategies to determine unknown additives in commercial plastics with a wide range of molecular structures and chemical properties. The measurements and characterization of PCA release in water and simulated agroecosystems will expand the studies dealing with occurrence, fate and effects of PCAs on such a scenario. Indeed, AddiPlaS will applied this methodology to determine the occurrence of target PCAs in surface and groundwater in an agroecosystem providing very valuable information under field conditions of potentially impacted water resources.
