Permeable pavements for microplastic pollution control: a laboratory analysis under mediterranean rainfall conditions

Abstract

Le ruissellement des eaux pluviales lave les surfaces urbaines et entraîne les microplastiques vers les plans d'eau récepteurs. L'impact négatif causé par ce polluant dans l'environnement, souligne la nécessité de le contrôler. L'utilisation potentielle des Systèmes de Drainage Urbain Durables, et des chaussées perméables en particulier, parvient à réduire considérablement les particules en suspension transportées par le ruissellement. L'étude vise à étudier l'efficacité des chaussées perméables à la rétention des microplastiques. La réponse d'un chaussée perméable est testée sous un régime pluviométrique moyen à Valence (Espagne). Les résultats montrent une réduction significative du nombre de microplastiques infiltrés à travers la chaussée perméable. Les fragments de polypropylène étaient les particules les plus retenues. Bien qu'il soit encore nécessaire d'améliorer l'efficacité de la rétention des fibres, la mise en place de chaussées perméables en milieu urbain peut contribuer à réduire la présence de microplastiques dans les déversements d'eaux pluviales.

Stormwater runoff washes off urban surfaces and drives microplastics to receiving water bodies. The negative impact caused by this pollutant in the environment, raises the need to control it. The potential use of Sustainable Urban Drainage Systems, and permeable pavements in particular, manage to significantly reduce suspended particles carried by runoff. The study aims to investigate how effective are permeable pavements at microplastic retention. The response of a permeable pavement was tested under the average rainfall regime of Valencia (Spain). The results showed a significant reduction in the number of infiltrated microplastics through the permeable pavement (94%). Polypropylene fragments were the most retained particles. Although it is still necessary to improve fibre retention efficiency, the implementation of permeable pavements in the urban environment may help to reduce microplastic content in stormwater runoff discharges.
