The spring 2013 regional ISES Tri-State (NJ, NY, PA) Chapter meeting was successfully held from 3:30 – 6:00 pm on Friday May 10, 2013 at the Environmental and Occupational Health Sciences Institute (EOHSI) of Rutgers University with a concurrent satellite meeting at Clarkson University via Skype. Dr. Nicky Sheats from Thomas Edison State College presented “The Role of Exposure Science in the Aftermath of Hurricane Sandy – the Point of View from a Community Leader.” There was also a presentation made by high school students from Central High School (Newark, NJ) and the Future City Program for the EPA Science-Citizen Project as well as three graduate student oral/poster presentations. A poster viewing session for these graduate students followed the meeting. Dr. Zhihua (Tina) Fan from EOHSI/UMDNJ-Rutgers University, former President of the Chapter, and Dr. Qingyu Meng, current Chapter President, recognized past officers/councilors for their service to the Chapter. Attendees also discussed the Chapter organizational issues at the meeting including the new Chapter website designed by Linda Everett (www.isestristate.org) and the newsletter initiative. The meeting committee included Dr. Qingyu Meng (EOHSI/UMDNJ/Rutgers), Dr. Zhihua (Tina) Fan (EOHSI/UMDNJ/Rutgers, High School Student Presentation Chair), Linda Everett (EOHSI/UMDNJ/Rutgers), Jennifer Therkorn (Rutgers, Meeting Chair), Dr. Kathy Black (EOHSI/UMDNJ/Rutgers, Graduate Student Presentation Committee), Dr. Michael Zelenka (ExxonMobil, Graduate Student Presentation Committee), and Kyung Sul (Clarkson University, Graduate Student Presentation Committee).

Computational modeling of the toxicodynamic effects in the respiratory system of mice due to nanoparticle inhalation
Dwaipayan Mukherjee, Steven G. Royce, Danielle Botelho, Andrew J. Gow, Panos G. Georgopoulos
Background: Nanoparticles are ubiquitous in the ambient air and might be produced as a result of industrial processes or might be a part of household consumer products as Engineered Nanomaterials (ENMs). Inhaled fine and ultrafine particles are arrested at various stages of the respiratory system. These ultrafine or nano-sized particles cause various toxicodynamic changes in the respiratory system in humans. Aim: The aim of this work is to develop a multiscale computational model for the physiologically based simulation of toxicokinetic and toxicodynamic processes associated with nanoscale particle inhalation. The model developed for mice will be ultimately extrapolated to humans. Methods: The model deals with pulmonary tissue with explicit focus on the cells and surfactant chemicals which regulate the process of breathing and respond to xenobiotics. The respiratory system processes are decomposed into four functional modules with alveolar surfactant dynamics, cellular dynamics, cellular inflammation and nanoparticle-surfactant interaction being considered separately. Pulmonary Type I and Type II cells, alveolar macrophages, and inflammatory cells were included in the model along with surfactant phospholipids, and surfactant proteins. The model also considers the mechanistic pathways involved in cellular inflammatory processes leading to changes in the levels of cytokines and cell counts in the lung. Results and discussion: The model was coded and the results compared with in-vivo measurements in mice on lung function response and lung lavage analysis following exposures to different types of nanomaterials.

Regional modeling for the Ozone Transport Commission (OTC) to support development of attainment strategies
Xiaogang Tang, Michael Ku, Winston Hao, Eric Zalewsky, Kevin Civerolo, Jin-Sheng Lin, Shan He, Tonalee Key, Panos Georgopoulos
The community multiscale air quality model (CMAQ), developed by USEPA, is used to simulate photochemical air pollution in the Northeast US for two scenarios involving past (2007) and projected future (2020) conditions. For the 2007 “base” case CMAQ inputs include 2007 emission inventories and 2007 meteorological data. For the 2020 “proxy” case, adjustment factors are applied to 2007 emissions and meteorological data are the same as for year 2007. Performance evaluation of the OTC 2007 CMAQ “Level 3” 12-km base case is presented here. CMAQ performed well in capturing the observed diurnal and temporal patterns with less error in daytime than in nighttime, which may be due to excessive vertical mixing in the nighttime.CMAQ performed better with rural monitors  (CASTNet) than with urban monitors (AQS). Level 3 future 2020 sensitivity simulation generally yields relative response factors (RRF) between 0.75 and 0.90 with higher values (lower reductions) in core urban areas and monitor “Bayonne” with future year design value above 85 ppb and several monitors in the 75 ppb level.

Modeling climate change effects on dynamics of allergenic Ambrosia (ragweed) and Artemisia (mugwort) pollen in US
Yong Zhang, Leonard Bielory, Zhongyuan Mi, Ting Cai, Panos G. Georgopoulos
Allergenic pollen acts synergistically with common air pollutants, such as ozone, to cause Allergic Airway Disease (AAD). Observed airborne pollen data from 1994 to 2011 at Fargo (North Dakota), College Station (Texas), Omaha (Nebraska), Pleasanton (California), Cherry Hill and Newark (New Jersey) in the US were studied to examine climate change effects on trends of annual mean and peak value of daily concentrations, annual production, season start, and season length of Ambrosia (ragweed) and Artemisia (mugwort) pollen. The Cooling Degree Hour (CDH) model was used to simulate start and end dates. The vegetation maps of ragweed and mugwort across US were generated based on analyses of observed airborne pollen counts and land use data. In the 2001-2010 period, ragweed was observed to flower 2-6 days earlier and its pollen season was found to be 1-8 days longer than in the 1994-2000 period. The mugwort pollen season at most of the studied stations also tended to start earlier and last for a longer duration. Pollen levels of both ragweed and mugwort changed differently for different stations. The optimum threshold CDH values of start date 2,353 and 40,213 degree hours for ragweed and mugwort, respectively. The optimum initial date and base temperature for the CDH model of start date were found to be August 1st and 30°C for ragweed; May 1st and 37°C for mugwort.

ISES Tri-State Chapter Council Meeting, February 21, 2013
Attendees: Qingyu Meng, Zhi-Hua (Tina) Fan, Mike Zelenka, Rose Zaleski, Joanne Held, Rick Opiekun, Phil Hopke, Jennifer Therkorn, Kathy Black

Meeting Summary:

  1. We asked for nominations for Secretary and Webmaster. Linda Everett was nominated for Webmaster. No nominations were received for Secretary. Jen, currently Student Councillor at Large, is willing to assume the position of Secretary. Tina suggested that the student with the next highest number of votes be asked to assume the position of Student Councillor at Large.
  2. The by-laws need to be clarified to determine if the chapter president can appoint members to fill vacant positions or if an election needs to be held. The ISES allows a temporary appointment with the stipulation that an election be held within 3 months of the vacancy. Joann suggested that we allow the President to appoint both the Secretary and Student Councillor at Large, but should the Treasurer’s position become vacant, we hold an election. The revised by-laws will be circulated for comments and input within the Chapter Council before sent out for vote by the general members of the ISES Tri-State Chapter.
  3. Rose informed us that a representative of each regional chapter attend the ISES board’s meetings. Meng will send an email to Rich Fenske asking that he be added to the next ISES board’s meeting. The chapter is also permitted to have a booth at the society’s general meeting.
  4. Some suggested topics for the spring regional meeting are: Exposome (Paul Lioy) and An Overview about Grant Applications (Eileen Murphy). Rick suggested that the exposures related to Superstorm Sandy (both the event and the remediation) would be very timely and interesting.
  5. The suggested time for the spring meeting is mid-May, after student finals. Phil pointed out a potential conflict with a major Adirondack meeting. We will need to have the regional meeting before or after.
  6. The meeting will be structured to have a shared webinar between EOHSI and Clarkson University. Tina will advise Meng on the requirements at EOHSI.
  7. One goal is to allow students to present posters at the meeting. Rick suggested that students email a poster hand-out version so that both sites could share student posters. Mike suggested that students be allowed a few minutes to present their posters during the meeting. A committee will be formed to rate the student posters.
  8. A membership meeting will be held prior to any presentations. Other societies (AWMA/SETAC) will be invited to attend the presentation portion. The invitations will be made through personal contacts with the other organizations.
  9. The newsletter will be released prior to the regional meeting (est. April). The newsletter will consist of an announcement of the election results, a mention of the ISES meeting in Basel, and the link to the new website (if ready). The newsletter will also mention any joint grants of interest and employment opportunities. Meng and Jen will send an email asking for input on: chapter affairs, joint grants of interest, and employment opportunities. Jen will take a lead on the newsletter.
  10. Meng will work with Linda on the website development. The draft webpage will be circulated for comments and input.
