Modelling the Marine Microplastic Distribution from Municipal Wastewater in Saronikos Gulf (E. Mediterranean)
Authored by Triantafyllou George

A three-dimensional hydrodynamic
model is coupled with a Lagrangian-Individual Based Model to simulate the
floating microplastics (<300μm) dispersal and transport in the Saronikos
Gulf. Considering municipal wastewaters as their main source, simulations were
carried out over 2011–2012. A comparison with hydrodynamic observational data
has shown that the model qualitatively reproduces the main circulation
structure and hydrodynamic features. To explore the fate and distribution of
microplastics, model results were analyzed taking into account the seasonal
variability of near-surface circulation. Simulation results gave a qualitative
description of affected areas from microplastics pollution, suggesting that the
most affected part of Saronikos Gulf is the coastal area that extends from
Psitallia Waste water treatment plant to the east. Despite some limitations,
this is a first model attempt to explore the dispersal and distribution of
microplastics in the Saronikos Gulf.
