AB  - Urbanization has led to considerable pressure on urban/suburban aquatic 
      ecosystems. Urban Wet Weather Discharges (UWWD) during rainfall events are a 
      major source of pollutants leached onto and into urban surfaces and sewers, which 
      in turn affect aquatic ecosystems. We assessed the ecotoxicity of the different 
      compounds identified in UWWD and identified the hazard represented by each of 
      them. To this end, hazard quotient (HQ) values were calculated for each compound 
      detected in UWWD based on their predicted no effect concentration (PNEC) values 
      and their maximum measured effluent concentrations (MEC(max)) found in the 
      dissolved part of UWWD. For the 207 compounds identified in UWWD, sufficient data 
      existed for 165 of them to calculate their PNEC. The ecotoxicity of these 
      compounds varied greatly. Pesticides represented a high proportion of the wide 
      variety of hazardous compounds whose HQ values were calculated (94 HQ values), 
      and they were among the most hazardous pollutants (HQ > 1000) transported by 
      stormwater. The hazard of combined sewer overflows (CSO) was linked mainly to 
      heavy metals and pharmaceutical compounds. Consequently, the monitoring of these 
      pollutants should be a priority in the future. The hazard level of certain 
      pollutants could have been underestimated due to their adsorption onto particles, 
      leading to their low concentration in the dissolved phase of UWWD. Hence, an 
      in-depth study of these pollutants will be required to clarify their effects on 
      aquatic organisms.
