Size Distribution of Trace Organic Species Emitted From Heavy-Duty

Additions and Corrections 2007, Volume 41, Pages 1962–1969

Sarah G. Riddle, Michael A. Robert, Chris A. Jakober, Michael P. Hannigan and Michael J. Kleeman*: Size Distribution of Trace Organic Species Emitted From Heavy-Duty Diesel Vehicles Ratios of analyte mass to total organic carbon (OC) mass (µg/ g) for the PM1.8 and the PM0.1 size fractions are shown in Tables 1 and 2, respectively. Ratios of analyte mass to total elemental carbon (EC) mass (µg/g) for the PM1.8 and PM0.1 size fractions are shown in Tables 3 and 4, respectively. The PM0.1 values published in the original manuscript did not incorporate the pyrolysis correction in the OC and EC values used to normalize the mass of each analyte. The PM1.8 values published in the original manuscript did not incorporate correction for adsorption artifacts measured with a downstream filter. The authors apologize for these errors. The revised values shown in Tables 1–4 confirm all of the conclusions made in the original manuscript with a single exception. The abundance of PAHs relative to OC in the ultrafine size fraction and the PM1.8 size fraction are approximately equal. There is not an enhancement of the relative PAH concentration in the ultrafine size fraction as was stated in the original manuscript.

E. Matthew Fiss, Krista L. Rule, and Peter J. Vikesland*: Formation of Chloroform and other Chlorinated Byproducts by Chlorination of Triclosan-Containing Products The value for a parameter in the Potential Health Significance section was reported incorrectly. The triclosan mass concentration (TC) used in the model was 3.3 mg triclosan/g soap, which represents the upper end of the range of triclosan concentrations measured in the tested soaps. If the reported value of 2.0 mg triclosan/g soap were applied, the resulting inhalational exposure would range from 3.5 to 14.5 mg/yr.
