TI  - Survey of bioavailable PCDDs, PCDFs, dioxin-like PCBs, and PBBs in air, water, 
      and sediment media using semipermeable membrane devices (SPMDs) deployed in the 
      Hartbeespoort Dam area, South Africa.

AB  - A survey of bioavailable polychlorinated dibenzo-p-dioxins (PCDDs), 
      polychlorinated dibenzofurans (PCDFs), dioxin-like PCBs (dl-PCBs), and 
      polybrominated biphenyls (PBBs) from ambient air, water and sediment was 
      performed in the Hartbeespoort Dam area in South Africa, a region where data on 
      highly toxic Stockholm Convention persistent organic pollutants (POPs) is scanty. 
      The sampling was designed to simulate POP bioaccumulation in benthic and aquatic 
      dwelling organisms as well as ambient air for estimation of ecological risk. The 
      objective was to survey the spatiotemporal distribution and fate of bioavailable 
      priority persistent organic compounds in the Hartbeespoort Dam in summer, autumn 
      and winter seasons and to validate the utility of a comprehensive two-dimensional 
      gas chromatography-time of flight mass spectrometry (GCxGC-TOF) method for 
      PCDD/F, PCB, and PBB analysis. The highest detection rates for bioavailable 
      priority POPs were for PCB 77 and PCB 126 which were detected in 15 and 16 of the 
      22 samples, though the majority of the detections were < LOQ for PCB 77. Overall, 
      PCB 126, PBB 10 and PBB 49 recorded the highest quantified bioavailable 
      concentrations per site in SPMDs deployed in the Hartbeespoort Dam. The SPMDs 
      deployed in air at the Magalies River site in winter recorded the highest toxic 
      equivalency quotient (TEQ) of 29.77 pg TEQ SPMD(-1). The highest TEQs recorded 
      for SPMDs deployed in the sediment phase were 10.2, 3.3, and 3.2 pg TEQ SPMD(-1), 
      recorded at the Harbour site in summer, Dam wall in summer and Harbour in winter 
      respectively. In water, SPMDs deployed at the Crocodile River site recorded the 
      highest TEQ of 0.81 pg TEQ SPMD(-1) in summer. TEQ data shows that air carries 
      significant bioavailable dl-toxicity compared to the water phase, and sediment 
      generally carries the highest dl-toxicity. Detection rates for bioavailable PBBs 
      were generally very low, with < 3 detections being quantified above the LOQ for 
      the majority of the sites. Statistical analysis of TEQs computed at all sites, 
      using AVOVA shows that the dispersion of TEQs in the Hartbeespoort Dam is largely 
      homogenous as the differences between the TEQs were insignificant (p > 0.05).
