The study emphasizes the need for deeper investigation to identify contamination sources and develop strategies to mitigate plastic pollution in soils.

Although the specific sources of these microplastics remain unidentified, the study suggests that agricultural practices may contribute to their presence in the soil.

A recent study published on December 26, 2024, by Ademe revealed that 76% of soil samples from various agricultural sites in France contained microplastics.

While the contamination of water bodies by plastics has been extensively documented, this study marks a significant step in understanding soil contamination, which has been less understood until now.

The average concentration of microplastics found in the analyzed soils was 15 particles per kilogram of dry soil, highlighting the pervasive nature of this issue.

The dominant types of microplastics identified were polyethylene and polypropylene, commonly associated with plastic packaging.

Researchers have identified agricultural practices as a contributing factor to plastic pollution, despite their recognized agronomic and environmental benefits.

To establish national references on soil contamination, Ademe utilized the soil quality measurement network from the Institut national de recherche pour l’agriculture, l’alimentation et l’environnement (Inrae).

The analysis involved 33 soil samples representing various land uses across metropolitan France, conducted by the Institut de recherche Dupuy de Lôme in Lorient, Morbihan.

There is an urgent call for continued research to monitor microplastic levels in soils, particularly in urban areas and overseas territories, to establish effective action plans.

This report aims to raise awareness about the widespread issue of microplastics in terrestrial environments and their potential implications for ecosystems and human health.

Plastic pollution poses significant environmental challenges, as plastics can take hundreds to thousands of years to decompose and can break down into harmful micro and nanoparticles.
