Asbestos Fate, Exposure, Remediation, and Adverse Health Effects Director: Ian A. Blair, Ph. D. Deputy Director: Trevor M. Penning, Ph. D. NIEHS Grant: P 42 ES 023720
Asbestos sites in EPA regions
Questions submitted to CEET by Ambler community • • • Can asbestos be remediated? • Is there a genetic pre-disposition to asbestosinduced mesothelioma? • Can asbestos-induced mesothelioma be prevented? • Is it possible to develop blood tests for asbestos exposure and mesothelioma? Is asbestos transported by water? Why is there a cluster of mesotheliomas among women in Ambler?

Project 1: Remediation of Asbestos Particles Co-PIs: Jane Willenbring and Brenda Casper (School of Arts and Sciences, University of Pennsylvania) Hypothesis: it will be possible to discover and quantify new, better ways to remediate asbestos sites in situ using a combination of hyper-accumulating plants and plants native to naturally metal rich serpentine soils coupled with their associated arbuscular mycorrhizal fungi (AMF)

Project 2: Mobility and Fate of Asbestos in Water Co-PIs: Douglas J. Jerolmack and Jane Willenbring (School of Arts and Sciences, University of Pennsylvania) Hypothesis: the mobility of asbestos particles in groundwater has been underestimated, and the unusually large aspect ratio and material properties make asbestos transport significantly different from other fine particles

Project 3: Social and Spatial Determinants of Asbestos Risk in a Superfund EJ Community Co-PIs: Frances Barg and Edward A. Emmett (Perelman School of Medicine, University of Pennsylvania) Hypothesis: The incidence of mesothelioma is related to occupational and non-occupational exposures in the Ambler area, to the proximity to the site, and to various social, lifestyle and economic factors
Materials and Methods Retrospective cohort study Data • • • 1930 US Census 1930 US Life Tables National Death Index Data elements • • • Age Gender Race Occupation Address Exposures of interest • • • Occupational exposure Paraoccupational exposure Environmental exposure
Project 4: Integrated Models of Malignant Mesothelioma Co-PIs: Joseph R. Testa (Fox-Chase Cancer Center) and Rebecca Simmons (Perelman School of Medicine, University of Pennsylvania) Hypothesis: Mutations in key tumor suppressor genes as well as epigenetic modifications, represent key molecular changes in mesothelial cell physiology that collectively contribute to mesothelioma formation following exposure to asbestos. The identification and characterization of such alterations may afford novel opportunities for early diagnosis, prevention and therapy.

Project 5: : Chemoprevention of Asbestos-Induced Malignant Mesothelioma Co-PIs: Melpo Christofidou-Solomidou and Steven M. Albelda (Perelman School of Medicine, University of Pennsylvania) Hypothesis: Secoisolariciresinol diglucoside (SDG) will interfere with inflammasome activation and ROS generation in asbestos-activated macrophages and mesothelial cells and thus interfere with initiation and propagation of damaging processes that would ultimately lead to mesothelioma formation

Project 6: Biomarkers of Asbestos Exposure Co-PIs: Ian A. Blair and Anil Vachani (Perelman School of Medicine, University of Pennsylvania) Hypothesis: Unsupervised serum metabolomics analysis using ultra-high resolution Liquid Chromatography-Mass Spectrometry will reveal novel biomarkers of biological response to asbestos that can be characterized

Community Engagement Core Co-PIs: Edward Emmett and Fran Barg (Perelman School of Medicine, University of Pennsylvania) Hypothesis: Concerns of the community can be translated into research projects
Penn SRP Center: local impact
Penn SRP Center: Biomarkers and Ambler Bo. Rit site
Research Translation Core Co-PIs: Richard Pepino and Robert Schenkel (Perelman School of Medicine, University of Pennsylvania) Hypothesis: The knowledge and discoveries of the Center can be translated into actionable items that will remediate asbestos waste (Projects 1 and 2) and reduce its adverse health effects (Projects 3 -6) by forging productive partnerships with the public and private sectors

Inter-Disciplinary Training Core Co-PIs: Trevor M. Penning and Jane Willenbring (Perelman School of Medicine, University of Pennsylvania) Mission. The Interdisciplinary Superfund Research Training Program provides cross-training in environmental science and environmental health science to ensure that all trainees master the necessary skills and have a sufficient knowledge base to understand the hazards of superfund waste sites and use this knowledge to help remediate these sites and their ensuing health effects.
