PROJECT GOALS

  • Characterisation of ports as sources of MP:

Genoa (IT), Olbia (IT), T

  • ulon

(FR)

  • Improving of MP sampling techniques
  • Understanding of MP dynamics: transport

and distribution

slide-5
SLIDE 5

PROJECT RESULTS

  • Development of

innovative MP sampling prototype

  • Mapping MP

concentrations and distribution in port areas

  • Dispersion models of how marine weather

conditions can afgect MP transport

MATERIALS AND METHODS

MP stomatal content Why Mugilidae?

  • common in ports
  • resistant to

stressors

  • known in literature

Bioindicator : Family Mugilidae

DISCUSSION

The analysed items are found mostly in the inner part

  • f the port compared to the mouth of Polcevera T
  • rrent,

due to a more relevant anthropic impact: sewages, losses from land and ships, street runofg, etc.

DISCUSSION

Hydrodynamic at the mouth of Polcevera T

  • rrent

rounds the corners

  • f

particles, forming a tridimensional granular shape Fragments are supposed to come mostly from land losses due to transport by wind, e.g. from the port waste collection site (cross)

DISCUSSION

  • A

relevant difgerence between water samples collected within the Port of Genoa is not present

  • Analysis on polymeric composition of the

items was performed in a parallel study in Ligurian Sea: around 50% of them were identifjed as cotton fjbres by FT-IR analysis. Analytical identifjcation will be performed

  • n samples from the Port of Genoa, also

testing Micro-Raman spectroscopy

CONCLUSIONS

  • Sampling of fjsh in the Port of Genoa was

performed during May 2019, in order to allow a comparison with the results from sediment and water samples collected again in the same area: analysis on these samples are still in progress

  • Mugilidae

from commercial fjshery in Oristano (IT) were collected during June 2019, in order to analyse their stomatal content: analysis on these samples are still in progress

  • The same approach will be applied on the
  • ther ports of the project area, as T
  • ulon
