NYC 9/11 Public Portal Document

Zero on September 12 and 13, 2001. The purpose of these studies was to evaluate the toxicity of '• ine particulate matter dust on the respiratory tract of mice and to compare well-studied )articulate matter reference samples, ranging from essentially inert to quite toxic, to those ollected at the World Trade Center site. These studies found that fine particles were dominated jy calcium containing compounds derived from World Trade Center building materials, and that a ugh exposure to World Trade Center fine particulate matter could cause mild lung inflammation . nd airflow obstruction in mice. These findings suggest that a similarly high exposure in people ould cause short-term respiratory effects such as inflammation and cough. Further, it is important to note that while this ERD is undergoing public review and omment, a process of external independent expert scientific peer review also is underway. These eview processes are the usual steps that EPA takes to ensure full and open participation by nterested parties. These steps also help EPA identify areas where a draft document could be mproved to strengthen both clarity and completeness of the draft. Comments from the public and rom the expert peer reviewers will be used to improve the draft report before it is finalized. Finally, EPA scientists, in collaboration with other federal and state environmental health irofessionals, as well as colleagues in academia and medical institutions, will continue to analyze vailable data on human exposures to environmental contaminants resulting from the World Trade Center disaster. This continuing work will help us to better understand the potential human health mpacts.
