#FridayScience 2

Tous on Fridays, we popularize one or more studies on microplastics in the Mediterranean.

Compilation of existing data on micro-plastic pollution in the Western Mediterranean on an interactive map

Nous avons compilé dans cette carte interactive  de l'ensemble des mesures des micro-plastiques de surface réalisées dans 4 scientific publications. 


2 things stand out:

  • The strong concentration on the whole of the Mediterranean. Indeed 1 item/m² represents 1,000,000 particles/km²

  • The unequal distribution of surface microplastics, these moving while being subjected to numerous constraints such as winds, currents as well as movements in the water column. They then sometimes leave the surface.
