Biocides in urban runoff : modelling emissions and transfer to the receiving environnement for different stormwater management scenarios

Biocides used in construction materials, and emitted into urban runoff durong rainfall are a growing concern for their impact on receiving ecosystems. Although biocide emissions from construction materials have been extensively studied in the laboratory or on the scale of test benches, few studies have quantified emissions at the scale of an urban neighbourhood and addressed the link between urban emissions of biocides, their fate in the stormwater management system and their transfer to the surface or underground aquatic environment. The development of measures to control stormwater at source that promote on site infiltration of urban runoff raises concerns about the fate of biocides in the soil of infiltration systems and their potential transport to the groundwater.
The aim of this PhD thesis is : (i) to assess the potential for biocides to be emitted from building facades in the urban context of the Paris region; (ii) to evaluate soil contamination levels and the fate of biocides in the soil; (iii) to assess the effect of different runoff management strategies at the scale of a building complex on the transfer of biocides into the environment.
The thesis will be conducted as part of the Francilian Observatory in Urban Hydrology (OPUR). It has a marked interdisciplinary character (urban hydrology, soil science, chemistry) and is rich in the diversity of approaches implemented: surveys, fieldwork, laboratory experimentation, modeling of emissions and reactive transfer in soil, construction and modeling of stormwater management scenarios.
