Thanh H. Nguyen,* Isam Sabbah, and William P. Ball: Sorption Nonlinearity for Organic Contaminants with Diesel Soot: Method Development and Isotherm Interpretation

Page 3598. The last seven rows of Table 1 3598 contained incorrect data in column 2 (Measured log Koc). Also two new footnotes are required. The revised Table 1 is shown below. In the Supporting Information, page 9, lines 189-193, and page 10, lines 198-200 are incorrect. The corrected Supporting Information was posted to the Web August 30, 2004.

a K ) K /f . Unit of K is mL of water/g of organic carbon. b These sorption experiments were conducted with 6 PAHs (phenanthrene, anthracene, oc d oc oc fluoranthene, benz[a]anthracene, benzo[k]fluoranthene, and benzo[g,h,i]pyrelene) simultaneously present. Final concentrations for the threephase equilibrium and solid-phase extraction in ref 16 were obtained from personal communication with Dr. Michiel Jonker (Institute for Risk Assessment Sciences, Utrecht University, The Netherlands).
