U.S. troops exposed to polluted air in Iraq, researchers report
Military personnel and contractors stationed in Iraq risk not only enemy gunfire, suicide bombers, and roadside bombs, but the very air they breathe often is polluted with dust and other particles of a size and composition that could pose immediate and long-term health threats, scientists report. Their ongoing study, begun in 2008, indicates that personnel in Iraq often breathe air polluted with the most worrisome kind of dust particles -- fine particles, or "particulate matter," that lodge deep inside the lungs. It is the first long-term study of the situation, with previous studies lasting less than a week.

*Instructions for joining chat room sessions
Chat Room Sessions from the ACS National Meeting in Anaheim
The American Chemical Society (ACS) Office of Public Affairs is offering the news media the opportunity to join press briefings during ACS's 241st National Meeting, whether covering the meeting onsite or from a remote location. This format will provide access to the increasing number of journalists who cover scientific meetings from their home base during the meeting, held March 27-31 in Anaheim, Calif.
Borrowing the popular chat room concept from the Internet, we will provide news media with access to both real and virtual chat room sessions during the Anaheim meeting.
Reporters attending the meeting can gather with scientists in an informal setting in our Press Briefing Room at the ACS Press Center in the Anaheim Convention & Exhibition Center, Hall C. There is no room number, but signs will point the way. Scientists will summarize their research and field questions. Offsite reporters can enter a virtual version of this Chat Room over the Internet. In addition to seeing and hearing the real-world activity, offsite reporters can submit questions.
Like hosts of a traditional chat room, we never know how many participants will join a session. Each session will proceed, regardless of attendance, so that digital transcripts can be made and posted online as a resource for individuals unable to attend.
Chat Room sessions begin at noon, Eastern daylight time, on Sunday, March 27, and continue during the week. Get a head start by registering at Ustream.tv, a live, interactive online video site.
