9th PCB Conference

Isrp researchers and trainees presented at the Ninth International PCB Conference in Kobe, Japan in October 2016!

Trainee Eric Uwimana presented a poster entitled "Risk assessment of disruption of estrogen receptor signaling pathway by OH-PCBs in Baikal seals; application of in vitro and in silico approaches." Fellow Iowa Superfund Research Program trainee Victoria Parker's poster was entitled " Inhibition of Human Steroid Sulfotransferases by Metabolites of Common Airborne Polychlorinated Biphenyls and its Potential for Altering Adipocyte Differentiation."

Both Victoria and Eric were in the five students awarded at the conference for poster presentations. Eric won best student poster presentation!

SRP researchers Dr. Larry Robertson, Dr. Gabriele Ludewig, Dr. Keri Hornbuckle, Dr. Hans Joachim Lehmler, and Dr. Michael Duffel gave oral presentations at the conference. Dr. Hornbuckle and Dr. Lehmler co-chaired Session 1 and Dr. Duffel co-chaired Session 3.

In addition, Dr. Andres Martinez and David Osterberg from the Iowa Superfund Research Program gave oral presentations at the international conference. Dr. Tim Mattes presented a poster for the conference.

Funding for this conference was made possible (in part) by 1 R13 ES 027325 - 01 from the National Institute of Environmental Health Sciences.



Dr. Lehmler Presents at International Symposium

December 19, 2016

Dr. Hans Joachim Lehmler, Synthesis Core Leader, presented at the International Symposium on Microsomes and Drug Oxidations at the University of California-Davis in October 2016. Dr. Lehmler presented on the "Metabolism of Polychlorinated Biphenyls."

Dr. Ludewig Honored with John Doull Award!

December 19, 2016


Dr. Gabriele Ludewig of the University of Iowa Superfund Program was awarded the prestigious John Doull Award at the 2016 Central States Society of Toxicology(CSSOT) meeting in November 2016. She has been a professor at the University of Iowa since 2003 when she was recruited to help re-establish the Interdisciplinary Graduate Program in Human Toxicology, which she serves as its Director of Graduate Studies.

She was president of the CSSOT in 2007-2008. For the past decade she has tenaciously pursued the question of whether persistent organic pollutants, like polychlorinated biphenyls, could be genotoxins. Her studies laid the foundation for a key finding in the recent IARC re-evaluation of the carcinogenicity of PCBs, by providing missing information on their initiating potential. Dr. Ludewig’ s contribution was critical to the elevation of PCBS to Group 1 Human Carcinogens.

John Doull is Professor Emeritus of Pharmacology and Toxicology at the University of Kansas Medical Center. He is author of the acclaimed reference book, Casarett & Doull’ s Toxicology. He has won numerous awards throughout his very distinguished career including the Mildred S. Christion Career Achievement Award from the Academy of Toxicological Services in 2013 and the American Academy of Clinical Toxicology Career Achievement Award in 2014.

New Report on Toxicology in Schools

October 10, 2016

Senator Ed Markey of Massachusetts held congressional hearings on the issue of PCBs in schools and then released The ABCs of PCBs: A Toxic Threat to America's Schools-(link is external) in October 2016. It lists key findings and recommendations regarding this vital topic.

Researchers Present to EPA

October 10, 2016

On September 8, 2016 Drs. Andres Martinez and Keri Hornbuckle of University of Iowa SRP (ISRP) traveled to Boston to meet US EPA Region 1 and Massachusetts Department of Envionmental Protection staff for the first time and share results of initial analyses from the collaborative air quality monitoring project at the New Bedford Harbor Superfund site (NBH). The projects pairs the ISRP, the Boston University Superfund Center, and the Toxics Action Center.

Funding for the project comes from the NIEHS Superfund Program. Initial results were shared at the meeting and a followup meeting is being arranged for November to share final results. This a great example of collaboration between centers and the affected communities!

Columbus Junction Students Visit!

July 01, 2016

On April 21, 2016 twenty- three students from the 7th and 8th grades at Columbus Junction School District visited the labs at the Iowa Superfund Research Program. The students were engaged by the program's inquiry based airborne PCB learning materials. The hands on materials demonstrate the sources, remediation, and human impacts concerning PCBs.
