Abstract
The accumulation of harmful and persistent organic molecules in soils and sediment is a major environmental concern. Removal by physical means such as riverine, lacustrine, or marine dredging can be prohibitively difficult, expensive, and may not ultimately prove effective. An alternative is to locally change the geochemistry to stabilize and sequester the contaminants and render them biologically unavailable. Ghosh et al. report on pilot projects to determine whether activated carbon would be so useful. Their Feature concludes with what more needs to be done to minimize anthropogenic chemical blights in soil and sediments.
