|Notification issued 7/8/13 at 7:15 PM. Brookhaven National Laboratory with NYPD will begin installing air sampling equipment Tuesday morning as part of a study called Subway-Surface Air Flow Exchange. Air sampling will be conducted in parts of the Bronx, Brooklyn, Queens, Staten Island and in Manhattan. In addition, researchers will disperse low concentrations of harmless gases known as perfluorocarbons at several subway and street-level locations in Manhattan for 30 minutes only during the morning. Data from the study will help first responders to better understand how airborne contaminants can travel through the system and enable them to develop emergency responses based on the results.
