WTC 9/11 Response


NIEHS Response to the World Trade Center


The September 11, 2001 terrorist attack on New York City's World Trade Center resulted in intense fires, and the subsequent collapse of the structures released tons of dust on lower Manhattan. The National Institute for Environmental Health Sciences (NIEHS) Worker Education Training Program (WETP) responded immediately, delivering 3,000 respirators to the site and providing expert support to coordinate occupational health issues during the recovery and cleanup processes. NIEHS supported researchers were also on-site, collecting environmental and air samples shortly after the disaster. NIEHS has launched a website that details the research and training activities of grantees that were funded to address immediate and long-term worker and community health issues arising from the World Trade Center (WTC) attacks. $6 million in WTC supplemental grants were awarded to current WETP grantees, with $4.5 million going to current SBRP grantees.
