Abstract
AbstractNaturally occurring and anthropogenic arsenic concentrations in soils, in conjunction with the current knowledge of its potential risk to human health, demonstrate a critical environmental and public health issue. These widespread arsenic concentrations potentially affect large human populations. There are locations worldwide where naturally occurring arsenic is considered to be and documented as a potential human health risk through the use of established risk assessment calculation approaches or as demonstrated by clearly measurable health or agricultural effects. This natural arsenic, exposed due to human activity and coupled with anthropogenic contributions, may be the number‐one soil contact environmental health issue in the world. Considering the relatively high natural arsenic concentrations in some New England locations, and with the advantage of access to a large soil arsenic database, this issue has been addressed as described herein for the Boston Basin and related areas. The article provides a summary of some large natural and anthropogenic arsenic data sets with comparison between them and a derivation of the natural and anthropogenic components in the Boston Basin. © 2010 Wiley Periodicals, Inc.
