Erratum
In the article “Temporal Variability of Tungsten and Cobalt in Fallon, Nevada” by Sheppard et al. [Environ Health Perspect 115:715–719 (2007)], “the Mann-Whitney test of medians” should have been “the Mann-Whitney test of differences in cumulative distribution functions.” This term was used in the last paragraph of the “Materials and Methods” and in Table 1.
Erratum
Davis et al. have reported an error in their article “A Retrospective Assessment of Occupational Exposure to Elemental Carbon in the U.S. Trucking Industry” [Environ Health Perspect 119:997–1002 (2011)]. On p. 1001 of their article (the next to last paragraph of the “Discussion”), there was a coding error in the original calculation: The percentage of person-years prior to 1971 was 8% and not 1.1%, as stated in the article.
The authors apologize for the error.
