      of polychlorinated biphenyls on gas chromatographic columns].
PG  - 441-4
AB  - Octanol-air partition coefficient (Koa) is a key descriptor for describing the 
      partitioning of organic pollutants, especially persistent organic pollutants 
      (POPs), between air and environmental organic phases. Thus it is necessary to 
      determine or predict the Koa values of these compounds. A novel method was 
      introduced to describe the quantitive relationship between the octanol-air 
      partition coefficients and gas chromatographic (GC) retention parameters A, B 
      values of polychlorinated diphenyls (PCBs) which are typical persistent organic 
      pollutants. By the correlation analysis between GC retention parameters A, B 
      values of PCBs on DB-1, DB-5 and DB-1701 columns, and their octanol-air partition 
      coefficients, a good linear relationship was found. The stepwise multiple linear 
      regression was used to derive binary equations with the correlation coefficients 
      greater than 0.99, and the standard deviations are less than 0.11. In addition, 
      based on the 153 experimental A, B values and 56 predicted A, B values, the Koa 
      values of the remaining 190 PCBs were predicted.
