Emissions and transport of urban biocides from facades to topsoil at the district-scale
Résumé
Biocides in building facades pose a chronic contamination risk at the district scale. • Emission, storage, and leaching of the herbicide terbutryn were quantified. • Terbutryn infiltrated into soil near facades and accumulated in topsoil. • Terbutryn concentrations in runoff near facades exceeded PNEC values. • The modeling approach enabled to quantify biocide fluxes at the district scale.
