TI  - Perfluorinated acids in air, rain, snow, surface runoff, and lakes: relative 
      importance of pathways to contamination of urban lakes.
PG  - 8328-34
AB  - Concentrations of perfluorinated acids (PFAs) were measured in various 
      environmental matrices (air, rain, snow, surface runoff water, and lake water) in 
      an urban area, to enable identification of sources and pathways of PFAs to urban 
      water bodies. Total PFA concentrations ranged from 8.28 to 16.0 pg/ m3 (mean 
      11.3) in bulk air (sum of vapor and particulate phases), 0.91 to 13.2 ng/L (6.19) 
      in rainwater, 0.91 to 23.9 ng/L (7.98) in snow, 1.11-81.8 ng/L (15.1 ng/L) in 
      surface runoff water (SRW), and 9.49 to 35.9 ng/L (21.8) in lake water. 
      Perfluorooctanoic acid (PFOA) was the predominant compound, accounting for > 35% 
      of the total PFA concentrations, in all environmental matrices analyzed. 
      Concentrations and relative compositions of PFAs in SRW were similar to those 
      found for urban lakes. SRW contributes to contamination by PFOA in urban lakes. 
      The measured concentration ratios of FTOH to PFOA in air were 1-2 orders of 
      magnitude lower than the ratios calculated based on an assumption of exclusive 
      atmospheric oxidation of FTOHs. Nevertheless, the mass balance analysis suggested 
      the presence of an unknown input pathway that could contribute to a significant 
      amount of total PFOA loadings to the lake. Flux estimates of PFOA at the 
      air-water interface in the urban lake suggest net volatilization from water.
