AB  - Aquatic ecosystems are exposed to multiple environmental pressures including 
      chemical contamination. Polycyclic aromatic hydrocarbons (PAHs) and 
      polychlorinated biphenyls (PCBs) are persistent organic pollutants (POPs) known 
      as preoccupying substances for the environment. Active biomonitoring (ABM) is a 
      surveillance method for polluted aquatic ecosystems measuring bioavailable 
      contamination. In this work, the aim was to quantify the total links between 
      environmental pressures and bioavailable contamination (for PAHs and PCBs) at the 
      French national scale. Based on 245 sites experimented by ABM from 2017 to 2019, 
      environmental pressures (anthropogenic pressures and environmental parameters) 
      were defined (point source landfill density, point source urban density, point 
      source industry density, point source road density, nonpoint source industry 
      density, nonpoint source road density, nonpoint source urban density, nutrients 
      and organic matter, slope, dams, straightness, coarse sediment, summer 
      precipitation, hydrographic network density and watershed size) and characterized 
      by one or a combination of measures called stressor indicators. The links between 
      environmental pressures and bioavailable POPs contamination (ABM measure) at a 
      large spatial scale were defined and quantified via structural equation modeling. 
      Point source urban density, nutrients and organic matter, summer precipitation, 
      straightness and point source industry density are correlated positively with PAH 
      bioavailable contamination. In contrast, nonpoint source urban density, nonpoint 
      source industry density, nonpoint source road density and watershed size are 
      positively correlated with PCB bioavailable contamination. The dominant pressures 
      linked to PAHs and PCBs were different, respectively local and large-scale 
      pressures were linked to PAH bioavailable contamination, and only large-scale 
      pressures were linked to PCB bioavailable contamination.
