AB  - Freshwater organisms remain at risk from bioaccumulation and biomagnification of 
      persistent organic pollutants (POPs), but factors affecting their transfer 
      through food webs are poorly understood. Here, we investigate transfer pathways 
      of polychlorinated biphenyls, polybrominated diphenyl ethers, and organochlorine 
      through a river food web, assessing the distribution and flux between basal 
      resources (n = 3), macroinvertebrates (n = 22), and fish (n = 1). We investigate 
      the effects of biological traits on the observed patterns and use trait-based 
      models to predict POP bioaccumulation. Transfer pathways differed among POPs and 
      traits such as habitat affinity, feeding behavior, and body size explained some 
      variation in POP burdens between organisms. Trait-based models indicated that 
      relationships between POPs, trophic transfers, and traits were relatively well 
      conserved across a wider array of river food webs. Although providing more 
      consistent predictions of POP bioaccumulation than steady-state models, 
      variability in bioaccumulation across food webs limited the accuracy of 
      trait-model predictions. As some of the first data to illustrate how ecological 
      processes alter the flux of pollutants through river food webs, these results 
      reveal important links between POPs and contrasting energetic pathways. These 
      data also show the utility of trait-based methods in the assessment of persistent 
      contaminants, but further field validations are required.
