Corrigendum

In Logue et al. (2011), the following errors were published:

In Table 1, the studies Gordon et al. (1998) and Seaman et al. (2007) were referenced. However, the correct studies should have been Gordon et al. (1999) and Seaman et al. (2009), and the references for these studies are as follows:

• Gordon, S.M., Callahan, P.J., Nishioka, M.G., Brinkman M.C., O’Rourke, M.K., Lebowitz, M.D. and Moschandreas, M.J. (1999) Residential environmental measurements in the National Human Exposure Assessment Survey (NHEXAS) pilot study in Arizona: preliminary results for pesticides and VOCs, Journal of Exposure Analysis and Environmental Epidemiology, 9, 456–470.

• Seaman, V.Y., Bennett, D.H. and Cahill, T.M. (2007) Origin, occurrence, and source emission rate of acrolein in residential indoor air. Environmental Science & Technology, 41, 6940–6946.

The reference Seaman et al. (2007) should not appear in this article.

In addition, errors were made in the columns Sample period, US homes, New homes, Criteria pollutants, VOCs, Aldehyde, SVOCs, Metals and Number of samples. The correct table is as follows:
