Corrections.

In "Developmental Toxicity of a Commercial Herbicide Mixture in Mice: I. Effects on Embryo Implantation and Litter Size" [Environ Health Perspect 110:1081-1085 (2002)], by Cavieres et al., some values in Tables 2 and 3 were incorrect.

In Table 3, the correct weight (mean [+ or -] SD) for control/winter is 1.43 [+ or -] 0.15 (n = 17).

Table 2 is shown below; values that have been corrected from the original table are shown in boldface.

The authors regret the errors.

during preimplantation and organogenesis (GD0-15).

In Figure 4B of "Diminished Experience-Dependent Neuroanatomical Plasticity: Evidence for an Improved Biomarker of Subtle Neurotoxic Damage to the Developing Rat Brain" by Wallace et al. [Environ Health Perspect 111:1294-1298 (2003)], the x-axis labels were incorrect. The corrected figure is shown below.

EHP regrets the error.

[GRAPHIC OMITTED]

The September Headliners article "Sperm Abnormalities in Men Exposed to PCBs and PCDFs" [Environ Health Perspect 111:A639 (2003)] incorrectly suggests that Yucheng is a geographic name when in fact it is the name (meaning "oil disease") for the infamous 1979 contaminated cooking oil incident. EHP regrets the error.
