ISRP investigators and the Research Translation Core began placing complete environmental data sets in public data repositories and journals. We have created a list by topic area.

Airborne PCBs:

Project 4 developed a method for measuring fluxes of PCBs from natural waters using air and water passive samplers deployed simultaneously in the Indiana Harbor and Ship Canal.  The complete data set can be found at Included on the website are 15 PCB subsets from this study.

The Analytical Core released a dataset for airborne PCBs and airborne OH-PCBs inside and outside urban and rural U.S. schools. It can be found at this University of Iowa dataset page. This dataset includes indoor and outdoor air mass, concentration, and associated quality control of PCBs and OH-PCBs in two rural schools and four urban schools, the latter near a PCB-contaminated waterway of Lake Michigan in the United States

Project 4 has released the data from a collaborative research project with the Boston University Superfund Research Program studying PCB congener concentrations in New Bedford Harbor. It can be found at The two Superfund Research Programs report the levels of airborne PCB concentrations at 18 locations for three consecutive periods, from July to November of 2015, and one extra period from July to August of 2016 in New Bedford, Fairhaven, Dartmouth, and Acushnet, MA, USA

Previous cycle Project 7 toxicity assessment data from subchronic inhalation exposure to a school air mixture (SAM) of PCBs. This is the first study conducted using environmentally relevant PCB mixtures and concentrations to mimic indoor air from a representative older school.


Project 4 reported the results of the first intensive survey of polychlorinated biphenyls (PCBs) in the surficial sediment of the Indiana Harbor and Ship Canal (IHSC) in East Chicago, IndianaThe data was created by analyzing samples collected in 2010. The complete data set can be found at Included on the website are 12 PCB subsets from this study.

 In addition, ISRP trainees Moala Bannavti and Don McKendry have created a website that helps visualize PCB air, water, and sediment samples collected in East Chicago. The website can be found at


PCBs in Paint

 Project 4 has released the dataset from their study on PCBs and paint colorants. It can be found at This is a dataset for PCB emissions from paint colorants, including file information, methods, investigators, and funding source for the project.


 PCBs in Food

The Analytical Core has released a dataset for PCBs in food. It measured the concentrations of 205 polychlorinated biphenyl (PCB) congeners in 26 food items. It can be found at


Biodegradation of Individual PCBs

Project 5 has developed more than 170 uncultured bacterium clones ribosomal RNA genes, partial sequences for their experiments. The full list can be found at the Iowa Superfund Research Program dataset on the NIEHS website at

In December 2020 Project 5 released a dataset describing biodegradation of individual PCBs by Paraburkholderia xenovorans LB400 in presence and absence of sediment slurry. These experiments were designed to further understand how biodegradation of PCB-degrading microorganisms can be limited by slow mass transfer of PCB molecules from the sediment particles to living cells.


Method for Quantification of OH-PCBs

The Analytical Core has created a dataset for a semi-targeted analytical method for quantification of OH-PCBs in environmental samples. It was released in 2019 and can be found at


Synthesis of PCBs

In July 2020 the Synthesis Core released the Dataset: Fatty Liver and Impaired Hepatic Metabolism Alter the Congener-specific Distribution of Polychlorinated Biphenyls (PCBs) in Mice with A Liver-specific Deletion of Cytochrome P450 Reductase. This excel data sheet summarizes quality assurance /quality control (QA/QC) data, including method detection limits (MDL), recovery rates of spiked ongoing precision and recovery standards (OPR) in both blank solvent and tissue matrix, limits of detection in both mass (ng) and concentration (ng/g tissue) from a study investigating the congener specific tissue distribution in mice exposed orally to Aroclor 1254.

The Synthesis Core also released datasets that were synthesized as analytical standards to study the metabolism of PCB 11. The data sets can be found at:
Authentication of 5-bromo-3-chloro-1,


In March 2020 they also released twelve datasets from previous publications regarding authentication of PCBs:
