New study estimates that a ton of lead dust may have been deposited in parks, homes, and schools near the cathedral.

With help from local tv station Univision 41, Earth Institute scientists tested how well Newark’s lead filters are working. The results support new findings from city officials.

Equipped with a field testing kit originally developed within Columbia’s Earth Institute, the “Lead-Free Kids Peru” project has tested hundreds of soil samples for the toxic metal — and dug up some startling results in the process.

To find out if this harmful metal is lingering in your backyard or local park, and to learn how to protect your family, bring a few scoops of soil to the Lamont-Doherty Open House on October 13.

An extensive investigation by the Reuters news agency has found that many children living on U.S. military bases may be exposed to hazardous levels of lead in decaying family housing.

High school students teamed up with Columbia University researchers to learn about local exposure to this toxic element. Along the way, they learned about history, field work, and the scientific process.

An ongoing study finds that 92 percent of private yards in Greenpoint may have unsafe levels of lead in their soil.

Undergraduates from Columbia and Barnard will be able to serve as research assistants on research projects related to sustainable development and the environment with distinguished faculty and researchers at the cutting edge of this burgeoning field.

A new study in the Bulletin of the World Health Organization shows how hot spots of lead contamination in soil can be pinpointed in order to safeguard children against drastic health effects. Researchers led by geochemist Alexander van Geen of Lamont-Doherty Earth Observatory, studied soil around two Peruvian mining towns, and found high lead concentrations… read more
