2005 AAAR PM Supersites Conference

Newsletter of the American Association for Aerosol Research

PARTICULARS

February 7-11, 2005 was an exciting time for AAAR as theAssociation continued to move forward into the 21stcentury with its second International Specialty Conference.The conference, held in Atlanta, Ga. was entitled “PMSupersites Program and Related Studies.” The meetingwas very successful with AAAR hosting nearly 400scientists, air quality managers and policy makers from awide range of key stakeholders. They includedrepresentatives from state, local, regional and federalagencies; academia; the private sector and others interestedin reducing uncertainties in our understanding ofatmospheric PM accumulation in urban and regionalenvironments. Meeting attendees came from 19 countriesincluding South America, Asia, India, Canada, andMexico. The 340 presentations were split between platform(2/3) and poster (1/3). The scope of the presentations wasbroad. It included the first part of the NRC paradigmcovering the fate of aerosols and related species fromsource-to-receptor through modeling and data analysis, andcompleting the cycle by tying concentrations observed atreceptors back to their source contributions. A major themewas the policy implications of these results, as well.

The meeting included five plenary sessions, one eachmorning of the conference. Mr. John Bachmann of the U.S.EPA, Office of Air Quality Planning and Standards(OAQPS), opened the meeting with the history of nearlyeverything. Beginning with the Big Bang, Mr. Bachmannmade it to about 1995 when he ran out of time. Next, Mr.Jeff Holmstead, Assistant Administrator for the Office ofAir and Radiation (OAR), provided an EPA perspective toair quality management in the U.S. and discussed how theefforts conducted through the Supersites Program andrelated programs support these efforts. Mr. DanGreenbaum, President of the Health Effects Institute,provided a historical perspective on progress that has beenmade since 1997 with understanding PM and healtheffects. Mr. Greenbaum indicated there appears to be nosingle PM component adversely impacting health, andtherefore, we must continue to look at all of thecomponents of the entire mixture. Dr. Jeff Gaffney thenrelated aerosols and global climate change indicating theshift in viewpoint from single city pollution (e.g., LosAngeles, Calif.) to regional smog to global smog aspopulations grow and cities move from isolated urbancenters to mega-cities. Finally, four of the Supersites

Program principal investigators provided preliminaryanswers to four of the science/policy relevant questionsbeing addressed in the Supersites Program and RelatedStudies Key and Policy Relevant Findings Synthesis. Themeeting was rounded out with an exhibition that included11 of the key aerosol measurement companies in the U.S.

Several key themes ran through the meeting from theresults that were presented:

1. Time resolved mass, and chemical and physicalcharacteristics of PM: Measurements of mass, particledensity, aerosol water, major and minor chemicalcomponents in the bulk aerosol, and size distribution dataincluding chemical components are all now possible withaveraging times ranging for a few seconds for some tohourly averages. The development and thorough evaluationof these methods over the last half-decade or so and theirapplication in major research efforts have providedsignificant advances to our understanding of atmosphericprocesses and source-receptor relationships. Thecontinuous measurement of nearly artifact-free aerosolmass now appears possible and likely ready for use inroutine monitoring networks.

2. Particle Mass Spectrometers: This is a specialclass of continuous methods that has advancedsignificantly over the last 5-10 years. Single particle massspectrometers are providing detailed chemical data ofsingle particles from 3 nm to 2 um in diameter, now almostroutinely in research studies. Aerosol mass spectrometers(AMS) provide detailed quantitative size and compositioninformation on very short time scales and are becomingwidely applied in research studies. Results from both typesof instruments provide key pieces of data forunderstanding processes and evaluating air quality modelsand have given us for the first time a clear picture ofultrafine particles and associated chemistry.

3. Size Distribution Measurements: Measurementsof size distributions from 3 nm to 10 µm are now availableby methods that appear to be ready for use in routinemonitoring networks. While not providing chemical data asgiven by the particle mass spectrometers, they are costeffective and provide additional information on sourcesand atmospheric processing of aerosols. Applications alsoinclude the measurement of aerosol water.

4. Speciation of Organic Carbon: Methods areadvancing for the sampling and analysis of the individualorganic carbon species in aerosols. Advances includemeasurements of polar organic compounds, use of smallersample sizes and faster throughput, the potentialmeasurement by particle mass spectrometers, andexpansion of the number of species measured and availablefor use in receptor type modeling efforts and for evaluatingemissions based models.

5. Modeling: Evaluation and application of bothChemical Transport Models and their modules and receptormodels were described. Advances over the last half-decadeinclude receptor models that use ambient data to identifysources without the need for emissions data from eachsource type, and the importance of additional tracer speciesthat allow for the apportionment of a variety of sources,including a clear separation of gas and diesel sourceimpacts.

Five of the top atmospheric science journals have beenchosen for special journal issues to support the publicationof results from this international conference. Tentativetitles and authors’ lists were due in March, and papers mustbe submitted by April 27, 2005. Late papers will beconsidered but must catch up with papers submitted ontime to be included in the special issues. All journals willfollow their standard submission and peer-review process.Please see the publications policy listed at the top of theopening page at www.AAAR.org.

2005 Annual Conference

4 AAAR

After receiving little response to myprevious editorial, which will be referredto as “The Poetic Call to Arms” from thispoint forward, I promised to throw thatidea in the editorial trashcan. The problemis … I spent last Thursday judging theBoulder Valley School District ScienceFair. I know that several of you have spenttime judging at your offspring’s schoolscience fair, so you know the range of

impressions: “Wow, his parents spent a lot of time on that!”;“How can a 10-year old figure out the math describing why tirespokes sometimes appear to be rotating backwards on TV?”;“Not another trebuchet!”; “I wish I understood circuits half aswell as this 13-yr old!”

At that age, I was thinking about playing soccer or tormentingmy siblings. I enjoyed math and science classes, but there wasno way that I actually wanted to do any of it outside of class.These young scientists, mathematicians, and engineers are manysteps beyond where we were at their age. They are usingcomputational tools that some of us can’t use now, and theyhave incredible access to informational resources. SO, what’smy point? Wouldn’t you love to walk into your daughter’sschool science fair and happen across a project titled, “ParticlesCool the Planet,” which measured the absorbance of aerosolsgenerated from combustion of different types of stuff?Information about aerosol origins, impacts, and characterizationexist, but a public-friendly clearing house would really helpconnect our work to those who are impacted by aerosols (i.e.,everyone). We should be the leaders in such an activity. So, whyonly two responses to “The Poetic Call to Arms?” I see threepossibilities.

Possibility 1. You (the reader) are already spending 60hours/week studying aerosols, and you can’t imagine findingmore time. After all, you have your own public (kids, spouses,significant others, cats, dogs, iguanas, etc…) to worry about.Possibility 2. You don’t care about reaching out to Joe Q.Public. You are studying aerosols only because they are cool,and you don’t have any interest in connecting to those scaryneighbors across the street (their dog only goes in your yard, sowho wants to help them).Possibility 3. Nobody reads the Letter to the Editor inParticulars.

Even though Possibility 2 is likely true for some, I reject it formost of us. “The Poetic Call to Arms” was not directed to thosefolks, but meant to give them some helpers. After all, some folksare out there connecting our aerosol work to the public. Let megive two brief examples, and I know there must be more. SusanneHerring spent an inordinate amount of time writing parts to theEPA PM Criteria document, which serves to inform public policy– this is a thankless task. Toni Miguel is going to spend a goodchunk of his summer in Hong Kong teaching a course aboutaerosols, specifically the U.S. experiences in understanding thehealth impacts and mitigation.

Possibility 1 is definitely a serious possibility. The solution tonot having enough time is … change the rotation rate of theplanet. No, the solution is … generate resources that will enableus to provide this connection to the public as part of our dailyworkload. This is feasible, and is happening (for example, thosewho work at NCAR are asked to make this ‘outreach’ part oftheir mission). I would love to hear from any of you with ideasabout outreach resources.

Truly, the most likely is Possibility 3. That puts the work backon me – I have to step up to the plate. So how do we (theeditorial staff) increase readership? On this front, well, we are atleast trying to produce a newsletter worth reading. Advertising –except by word-of-mouth – isn’t an option given our editorialstaff budget ($0). We could throw a contest. Yeah, right. Hey,wait a minute – that is a great idea…Let’s have a contest;something fun, something easy, and something that doesn’t takemuch time. I got it – let’s have a limerick contest! SO, to theseven of you actually reading this, could you please spread theword about the 2005 Aerosol Limerick Contest? Read on fordetails.

The 2005 Aerosol Limerick Contest.Winner:The winner, and two runner-ups, will get their limerickpublished (in the Summer 2005 issue of Particulars)! AND, Iwill personally buy the winner a drink of their choice at the2005 Annual Conference in Austin.Rules:(a) You must write a limerick that has something to do with

aerosols.(b) You can submit up to 3 limericks.(c) Limericks are due June 21.(d) A team of 5 judges will evaluate the limericks based on

format, content, and humor.

Limerick Format:Every limerick consists of 5 lines. Lines 1, 2, and 5 rhyme, andeach has 8 or 9 syllables. Lines 3 and 4 rhyme, and each has 6syllables.

Example (my first entry):If You PleaseBioaerosols make me wheeze.You can find them on every breeze.From the flu to pollen,They’re comin’ callin’.So cover your mouth when you sneeze.

Send all entries to me via e-mail (hannigan@colorado.edu). Iam looking forward to reading some quality work (andgenerating a few more of my own). So go for it!

Sincerely,Mike Hannigan

Thermo Electron In late January of this year, Thermo Electron Corporationannounced the launch of its iSeries line of gaseouspollutant analyzers. This line, with monitoring capabilitiesfor a broad range of gaseous pollutants, was introduced toenhance the capabilities of Thermo’s cSeries line ofanalyzers and to respond to compliance-related needs.

The rapid industrialization of developing nations hasplaced an increased emphasis on the necessity to monitorglobal air quality which insures the well being of bothpeople and the environment. Furthermore, via the KyotoProtocol, climatologists and international governmentbodies are working to promote the reduction of harmfulemissions, otherwise known as greenhouse gases, in theatmosphere. By providing accurate and reliablemeasurements for both urban air quality monitoring andstack gas emissions monitoring, the iSeries is the first lineof defense in this global challenge to improve air quality.

Thermo Electron has been serving the regulatory andindustrial safety communities with dependable monitoringsolutions since 1970, and dating back to the original CleanAir Act. Deriving from a wealth of experience andcustomer input, Thermo’s new line of products combinerugged, plant-proven components, advanced electronics,and operator friendly software with a flexible, easy-to-service package that establishes a new benchmark for gasanalysis instrumentation. With added features likeEthernet Connectivity, Flash Memory, Programmable SoftKeys and Captive Thumbscrew Component Mounting, theiSeries is now easier to interface, easier to maintain andeasier to use.

Key enhancements made to the iSeries line of analyzersinclude:

New Ethernet Port – Built-in Ethernet connectivityenables easy networking with existing control and datamanagement systems, as well as convenient remote accessallowing for system status review from any Internetconnection.

Product Commonality – The new analyzers containfewer parts and, from one gas to another, share a similardesign, user interface and many common componentsmaking them easier to service and easier to train. Once auser becomes familiar with a single instrument, systemconformity allows for familiarity with the entire line.

Easier User Interaction – A larger, more intuitivedisplay and redesigned interface results in easieroperation. With fast, intuitive navigation and simple,menu-driven programming, the software is easy to learn,even for inexperienced operators.

Enhanced I/O functionality - New connectivitycapabilities make it easy to integrate iSeries instrumentsinto various plant operations and data managementsystems. The new line of instruments are also compatiblewith Thermo’s earlier generation analyzers allowing foreasy fit into current monitoring systems.

In mid-December 2004, the U.S. EnvironmentalProtection Agency released the first PM2.5 air qualitystandard attainment/non-attainment designations. Whileambient fine particle levels have improved recently,approximately one third of all Americans still live in non-attainment areas for the new standard. As for review ofthis standard, the EPA Staff Paper summarizing the PMCriteria Document is in the revision phase; hopefully, wewill have some news by the next newsletter. Furtherinformation and related links are available atwww.epa.gov/pmdesignations/.

Could the residential combustion of biofuels really beglobally important source of aerosol black carbon? In arecent paper in Science, Venkataraman and colleaguesanswer, “Yes.” An analysis of the emissions fromresidential biofuel combustion showed that theseemissions contain relatively more BC than other biomasscombustion sources like wildfires. Combining theirmeasured emission factors with estimates of residentialbiofuel, the authors show that residential biofuelcombustion is the largest source of BC in India(Venkataraman et al (4 March 2005). Science, 307, 1454 –1456.).

In January 2005, the Interim Report on the Committee onChanges in New Source Review Programs for StationarySources of Air Pollutants was released on the NationalAcademy of Science’s Web site(www.nap.edu/catalog/11208.html). This report includesan overview of relevant background information and

describes the methodology that will be used by theCommittee to evaluate recently proposed changes in theNew Source Review program in their final report(scheduled for the end of 2005).

A recent study conducted in the Boston area suggests thattwo drugs normally taken for some heart problems andhigh blood pressure – calcium channel-blockers and beta-blockers – can at least partially mitigate the association ofelevated O3 and PM2.5 ambient concentrations with adversechanges in heart rate variability (Park et al (2005).Environmental Health Perspectives, 113(3), 304 – 309.Available online athttp://ehp.niehs.nih.gov/members/2004/7447/7447.html).

What component (or which source) of PM2.5 is causing theobserved adverse health effects? We may be trying toanswer this one for a while. A review article that focusedspecifically on addressing our current state of knowledgewith regard to one PM2.5 component, sulfate, waspublished in January. It sounds like we will be hearing alot about this topic in the not-so-distant future (Grahameand Schlesinger (2005) Inhalation Toxicology, 17, 15-27.).

The American Association for Aerosol Research (AAAR)and the International Society for Aerosols in Medicine(ISAM) are pleased to announce an exciting change in theThomas T. Mercer Joint Prize. The award honors thelegacy of Thomas T. Mercer, an outstanding researcherand author whose work encompassed aerosol physics andchemistry as well as inhalation toxicology, industrialhygiene, and health physics. Thanks to generous supportby the Mercer Family Foundation, the award amount forthe Mercer Prize has been substantially increasedbeginning with the award made at the ISAM meeting inPerth, Australia, March 14-18, 2005.

As the recipient of the 2005 award, Dr. Andrew Clark waschosen as a result of his work as an accomplished scientistwith extensive experience in the fields of aerosol scienceand pharmaceutical inhalation science. He has headedpharmaceutical research and development groups at FisonPharmaceuticals, Genentech, and Nektar Therapeutics,where he currently acts as a Senior Fellow and ChiefScientist. Dr. Clark has been characterized as someonewho is extremely fast at deducing problems and solutions,very practical, and quite talented at leading researchteams.

Thomas Mercer was born in Victoria, British Columbia,Canada in 1920. He received a degree in Physics andChemistry after World War II from San Jose College andbecame an Instructor at the University of Washington. In1955, he started his graduate studies at the IndustrialHygiene-Health Physics Program at the University ofRochester, during which he worked in the laboratory ofDr. C. N. Davies in London. He returned to Rochester tocomplete his Ph.D. in 1957, authoring several papers onparticle charging and precipitation and on airborne decayproducts of radon.
