AB  - Polychlorinated biphenyls (PCBs) are classified as persistent organic pollutants 
      (POPs). Concentrations of 209 PCB congeners as well as profiles of the ten 
      homologues were determined in stormwater sediments collected from various 
      (primarily roadway) sites with different land use. The total PCB concentrations 
      ranged from 8.3 to 57.4 ng/g dry weight (dw), with a mean value of 29.2 ng/g dw. 
      PCB concentrations varied with nearby land use. Higher stormwater sediment PCB 
      concentrations were found in dense urban areas (average: 39.8 +/- 10.5 ng/g) and 
      residential areas (average: 35.3 +/- 6.2 ng/g) compared to highways passing through 
      greenspace (average: 18.0 +/- 0.4 ng/g). The number of chlorines per biphenyl 
      ranged from 3.63 to 5.39 and the toxic equivalency (TEQs) of the PCBs were 
      between 1.5 and 18.0 pg/g at all sites. A non-Aroclor congener, PCB 11, was 
      detected in all samples and was dominant at two sites. PCBs were sorbed to 
      smaller stormwater particulate matter (</=75 mum) at higher concentrations compared 
      to larger particles (>75 mum). PCB sorption tended to increase with the total 
      organic carbon (TOC) of the particulate matter in the sediment samples. However, 
      greater PCB mass (almost 80%) was present in the larger particles. Information on 
      sediment PCB concentrations from different land uses, along with stormwater 
      particulate matter data can allow the estimation of PCB loads and load reductions 
      using stormwater control measures.
