EPA Air Quality Criteria for Particulate Matter

 
The EPA is releasing for public comment the draft "Air Quality Criteria for Particulate Matter (External Review Draft)." The purpose of this document is to assess the latest scientific information on the health effects of airborne particulate matter (PM) for use in the next periodic review of the National Ambient Air Quality Standards for PM. This draft report reviews new studies on particulate matter, including studies that examine the susceptibility of infants and children to health effects from PM, the cardiovascular affects associated with PM, and the exacerbation of asthma and other respiratory conditions by PM. Additional PM studies currently nearing completion will be considered for the next draft of the document, which will be released in mid-year 2000. The EPA will present its current draft report at a public meeting for review by the Clean Air Scientific Advisory Committee within the next several months. A future Federal Register notice informs the public of the exact date and time of that meeting. The draft is available on the Internet at: www.epa.gov/ncea or on CD ROM by calling 919- 541-4826. Written comments on the draft must be submitted by Jan. 14 to the Project Manager for Particulate Matter, National Center for Environmental Assessment- RTP Office (MD-52), U.S. EPA, Research Triangle Park, N.C. 27
