Unraveling Microplastic Fate and Transport in Aerobic and Anaerobic Sediment Conditions

Poster 144

  • To replicate oxidized and reduced circumstances, the MP-sediment interaction will be studied in three sediment environments: aerobic (oxidized environment), anaerobic (reduced conditions), and cyclic aerobic-anaerobic environments.

  • As part of the experimental setup, five continuously stirred tank (CSTR) batch reactors (2000 mL flaks) operated for 60 days will be used. Two will act as controls while the remaining ones will have different environments.

  • The aerobic condition will be achieved through the use of an air diffuser, while the anaerobic reactors will be sealed to the environment and purged with nitrogen gas.

  • Dissolved oxygen (DO), Temperature, pH, Oxidation Reduction Potential (ORP), nutrient content, and organic matter quantification analyses will be done periodically to sustain the required experimental environments.

  • Quantification and the morphology of the microplastics will be assessed using a UV‐VIS (Ultraviolet‐Visible) spectrometer, and the MP chemical characterization will be conducted using Fourier Transformed Infrared (FTIR) spectroscopy.
