Dataset for hydroxylated polychlorinated biphenyls are emerging legacy pollutants in contaminated sediments

Panithi Saktrakulkla, Xueshu Li, Andres Martinez, Keri C Hornbuckle & Hans-Joachim Lehmler
We measured the concentrations of 837 hydroxylated polychlorinated biphenyls (OH-PCBs, in 275 chromatographic peaks) and 209 polychlorinated biphenyls (PCBs, in 174 chromatographic peaks) in sediments from New Bedford Harbor in Massachusetts, Altavista wastewater lagoon in Virginia, and the Indiana Harbor and Ship Canal in Indiana, USA, and in Aroclors 1016, 1242, 1248, and 1254. We used the correlation between homologs and the peak responses to quantify the full suite of OH-PCBs including those without authentic...

Dataset for PCB Emissions from Paint Colorants

Jacob C. Jahnke & Keri C. Hornbuckle
Polychlorinated biphenyls (PCBs) are known human carcinogens that are byproducts of pigment manufacturing and found in colorants used to tint consumer paints sold in the United States and elsewhere. This dataset contains the measurements of PCBs found in colorants and the PCBs emitted from colorants into air. 9 separate colorants (7 from 2018 and 2 from 2009) were examined. To quantify the gas-phase emissions of ∑PCBs, we used polyurethane foam (PUF) to capture emissions from...

Dataset for Room-to-Room Variability of Airborne PCBs in Schools and the Application of Air Sampling for Targeted Source Evaluation

Moala K Bannavti, Keri C Hornbuckle, Jacob C Jahnke & Rachel F Marek
This dataset describes airborne polychlorinated biphenyl (PCB) congener masses and concentrations from room-to-room in Columbus Secondary School, a minority-predominant, low-income, public school in rural Iowa (Bannavti and Jahnke et. al., In Review). These experiments were designed to understand if total PCB concentration and congener profiles (distribution) change in a single school depending on the location. The data resulting from this study can inform future PCB analysis and remediation efforts in schools.

Model outputs of surface PM2.5 concentration

Huanxin-Jessie Zhang & Jun Wang
Exposure to ambient PM2.5 (fine particulate matter with aerodynamic diameter less than 2.5 µm) can lead to adverse health effects. Air quality forecasting of PM2.5 is critical for informing the general public and decision makers to take preventive cautions. Air quality forecasting models of PM2.5 are subject to large uncertainties due to factors such as the incomplete representation of the physical and chemical processes. Here we develop a computationally efficient bias-correction framework to improve surface...

Lung Anatomy + Particle Deposition (lapd) Mouse Archive

Reinhard R Beichel, Robb W Glenny, Melissa Bauer & Christian Bauer
The mouse is the most commonly used animal model for toxicology risk assessments and tobacco smoke exposure. Because it is not possible to study every substance exposure or varying exposure conditions, mathematical models and computer simulations are employed to fill the gap or to extend the range of experimental data. However, computational toxicology is limited in its application to mouse inhalation exposure studies because of the lack of high-resolution accurate airway geometries needed for modeling...

Dataset: Fecal PCB metabolites in germ-free mice compared to conventional mice

Xueshu Li
The PCB metabolome in feces of germ-free (GF) and conventional (CV) mice was systematically explored with nontarget high-resolution mass spectrometry (Nt-HRMS). The total PCB metabolite levels were dose and gut microbiome dependent. This finding demonstrate that the gut microbiome plays a role in the metabolism and excretion of PCB metabolites. This dataset summarizes relative levels of individual PCB metabolites in feces of both CV and GF mice, including the raw data files collected from instrument...

Instances for 'Impact of Autonomous Vehicle Assisted Last-Mile Delivery in Urban to Rural Settings'

Ann M Campbell, Barrett W Thomas & Sara J. Reed
These test instances are used to reflect real-world changes in customer geographies based on their locations. The test instances are constructed from different counties in Illinois. Each county in the case study has ten instances that each include a depot location (denoted by 0) and 50 customers (denoted as 1-50). Three of the counties (Cook County, Adams County, and Cumberland County) also have five instances that each include a depot location (denoted by 0) and...

Videos of Blast Wave Experiment in Dusty Plasma

Anton Kananovich
Data are provided here, in video format, for one of the shock-wave experiments reported in the PhD thesis of Anton Kananovich. The experiment was performed using a dusty plasma, which was manipulated by an exciter wire that was moved at a supersonic speed to launch a shock wave. The data were recorded by a high-speed video camera, viewing from the top. Further details are provided in the thesis.

Spatial data for \"Remapping and visualizing baseball labor\"

Katherine Walden
Recent baseball scholarship has drawn attention to U.S. professional baseball’s complex twentieth century labor dynamics and expanding global presence. From debates around desegregation to discussions about the sport’s increasingly multicultural identity and global presence, the cultural politics of U.S. professional baseball is connected to the problem of baseball labor. However, most scholars address these topics by focusing on Major League Baseball (MLB), ignoring other teams and leagues—Minor League Baseball (MiLB)—that develop players for Major League...

WRF-Chem model outputs of surface PM2.5 concentrations in India during November 2017

Behrooz Roozitalab, Gregory R Carmichael & Sarath K. Guttikunda
Northern India experienced an extreme air pollution episode in November 2017. We used WRF-Chem model to simulate this episode. In order to capture PM2.5 (fine particulate matter with aerodynamic diameter less than 2.5 µm) peaks, we modified input chemical boundary conditions and biomass burning emissions using a set of experiments. This dataset includes the simulation results for the base scenario surface PM2.5 concentrations, which showed the best statistics when evaluated against different observation and satellite...

Dataset Describing Biodegradation of Individual Polychlorinated Biphenyl Congeners (PCBs) by Paraburkholderia xenovorans LB400 in presence and absence of sediment slurry

Keri C Hornbuckle, Christian M. Bako, Timothy E Mattes, Rachel F Marek & Jerald L Schnoor
This dataset describes the biodegradation of polychlorinated biphenyl (PCB) congeners by Paraburkholderia xenovorans LB400 in absence and presence of PCB-contaminated sediment slurry, over time (Bako et. al., In Review). 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. The data resulting from these experiments can inform future experimental design and be reused by other researchers...

Dataset for a semi-target analytical method for quantification of OH-PCBs in environmental samples

Panithi Saktrakulkla, Ram C Dhakal, Hans-Joachim Lehmler & Keri C. Hornbuckle
Hydroxylated polychlorinated biphenyls (OH-PCBs) are oxidative metabolites of PCBs and residuals found in original Aroclors. OH-PCBs are known to play a role as genotoxicants, carcinogens, and hormone disruptors, and therefore it is important to quantify their presence in human tissues, organisms, and environmental matrices. Of 837 possible mono-OH-PCBs congeners, there are only ~70 methoxylated PCB (MeO-PCB) standards commercially available. Hence, a semi-target analytical method is needed for unknown OH-PCBs. The mass concentrations of these unknowns...

Toxicity assessment data from subchronic inhalation exposure to a school air mixture (SAM) of PCBs

Hui Wang, Susanne Flor, Andrea Adamcakova-Dodd, Laura E Gosse, Violet E Klenov, Jeffrey M Stolwijk & Peter S Thorne
This dataset is related to research article: Comprehensive subchronic inhalation toxicity assessment of an indoor school air mixture of PCBs. In this research, we generated a school air mixture (SAM) of airborne polychlorinated biphenyls (PCBs), designed to match the profile of an older school from our adolescent cohort study (the AESOP Study). Female Sprague-Dawley rats were exposed either to SAM or filtered air (sham) in nose-only exposure systems, 4 h/day for 4 weeks. Positive control...
