Therefore, in this work, road and parking lot runoff from four sites with contrasting traffic levels were analyzed for a very broad spectrum of molecules and elements. A total of 128 pollutants and micropollutants were monitored, including inorganic (n = 41) and organic (n = 87) pollutants. Both the dissolved and particulate phases were considered. For a reduced number of samples, non-targeted screening by high-resolution mass spectrometry (HRMS) was carried out. For targeted screening, the contamination profiles were quite homogeneous, but the concentrations significantly differed between the different sites. Sites with the highest traffic density exhibited the highest concentrations for polycyclic aromatic hydrocarbons (PAHs), some traffic-related metals, alkylphenols and phthalates. Overall, for most micropollutants, the parking lot runoff exhibited the lowest concentrations, and the specificity of this site was confirmed by its HRMS fingerprint. Non-target screening allowed the sites to be discriminated based on the occurrence of specific compounds. Unlike the results of targeted screening, the HRMS intra-site variability was lower than its inter-site variability. Unknown substances were tentatively identified, either characteristic of each site or ubiquitous of all samples.}, language = {en}, number = {3}, urldate = {2022-01-31}, journal = {Water}, author = {Gasperi, Johnny and Le Roux, Julien and Deshayes, Steven and Ayrault, Sophie and Bordier, Louise and Boudahmane, Lila and Budzinski, Hélène and Caupos, Emilie and Caubrière, Nadège and Flanagan, Kelsey and Guillon, Martin and Huynh, Nina and Labadie, Pierre and Meffray, Laurent and Neveu, Pascale and Partibane, Chandirane and Paupardin, Julien and Saad, Mohamed and Varnede, Lucie and Gromaire, Marie-Christine}, month = jan, year = {2022}, note = {Number: 3 Publisher: Multidisciplinary Digital Publishing Institute}, keywords = {micropollutants, non-target screening, road runoff, stormwater, target screening}, pages = {394}, }
