Limited data from previous studies analyzing arsenic levels in sand samples collected from CCA playgrounds are inconsistent and cannot be directly translated to the(More)
We commend Kwon et al. (2004) for their very interesting study of arsenic on the hands of children in contact with chro-mated copper arsenate (CCA)-treated wood structures and soil after playing in playgrounds. We would like to comment on some of their cited references and discuss the implications of the reported arsenic concentrations found in their(More)
