Transformation of Phenanthrene by Mycobacterium sp. ELW1 and the Formation of Toxic Metabolites

Creator:: Schrlau, Jill E.
Abstract:: The ability of Mycobacterium sp. ELW1, a novel microbe capable of alkene oxidation, to co-metabolize phenanthrene (PHE) was studied. ELW1 was able to completely co-metabolize PHE, at different concentrations below its water solubility limit, in an aqueous environment. The alkene monooxygenases in ELW1, used to initiate oxidation of PHE, were...

Comparison between lichen, conifer needles, resin-based passive air sampling devices (PASDs), and snow to monitor semi-volatile organic compounds (SOCs) in the atmosphere

Creator:: Schrlau, Jill E.
Abstract:: The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...

Contaminants of Emerging Concern in Fish from Western U.S. and Alaskan National Parks — Spatial Distribution and Health Thresholds

Creator:: Pritz, Colleen M. Flanagan, Schrlau, Jill E., Simonich, Staci L. Massey, and Blett, Tamara F.
Abstract:: Remote national parks of the western U.S. and Alaska are not immune to contaminants of emerging concern. Semivolatile organic compounds (SOCs) such as pesticides and PCBs can selectively deposit from the atmosphere at higher rates in cold, high-elevation and high-latitude sites, potentially increasing risk to these ecosystems. In the environment,...

Organic contaminants in western pond turtles in remote habitat in California

Creator:: Meyer, Erik, Eskew, Evan A., Chibwe, Leah, Schrlau, Jill, Simonich, Staci L. Massey, and Todd, Brian D.
Abstract:: Remote aquatic ecosystems are exposed to an assortment of semivolatile organic compounds (SOCs) originating from current and historic uses, of local and global origin. Here, a representative suite of 57 current- and historic-use pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons were surveyed in the plasma of the western pond turtle...

Relative Influence of Trans-Pacific and Regional Atmospheric Transport of PAHs in the Pacific Northwest, US

Creator:: Lafontaine, Scott, Schrlau, Jill, Butler, Jack, Jia, Yuling, Harper, Barbara, Harris, Stuart, Bramer, Lisa M., Harding, Anna, and Simonich, Staci L. Massey
Abstract:: The relative influences of trans-Pacific and regional atmospheric transport on measured concentrations of polycyclic aromatic hydrocarbons (PAHs), PAH derivatives [Nitro- (NPAH) and Oxy-(OPAH)], organic carbon (OC), and Particulate Matter (PM) less than 2.5 μm in diameter (PM₂.₅) were investigated in the Pacific Northwest, USA in 2010-2011. Ambient high volume PM₂.₅...

Metabolism and Excretion Rates of Parent and Hydroxy-PAHs in Urine Collected after Consumption of Traditionally Smoked Salmon for Native American Volunteers

Creator:: Motorykin, Oleksii, Santiago-Delgado, Lisandra, Rohlman, Diana, Schrlau, Jill E., Harper, Barbara, Harris, Stuart, Harding, Anna, Kile, Molly L., and Simonich, Staci L. Massey
Abstract:: Few studies have been published on the excretion rates of parent polycyclic aromatic hydrocarbons (PAHs) and hydroxy-polycyclic aromatic hydrocarbons (OH-PAHs) following oral exposure. This study investigated metabolism and excretion rates of 4 parent PAHs and 10 OH-PAHs after the consumption of smoked salmon. Nine members of the Confederated Tribes of...

Relative influence of trans-pacific and regional atmospheric transport of PAHS in the Pacific Northwest, USA

Creator:: Lafontaine, Scott, Schrlau, Jill, Butler, Jack, Jia, Yuling, Harper, Barbara, Harris, Stuart, Bramer, Lisa M., Waters, Katrina M., Harding, Anna, and Simonich, Staci L. Massey
Abstract:: The relative influences of trans-Pacific and regional atmospheric transport on measured concentrations of polycyclic aromatic hydrocarbons (PAHs), PAH derivatives [Nitro- (NPAH) and Oxy-(OPAH)], organic carbon (OC), and Particulate Matter (PM) less than 2.5 μm in diameter (PM₂.₅) were investigated in the Pacific Northwest, USA in 2010-2011.

Heterogeneous Reactions of PM-Bound PAHs and NPAHs with NO₃/N₂O₅, OH Radicals, and O₃ under Simulated Long-Range Atmospheric Transport Conditions: Reactivity and Mutagenicity

Creator:: Jariyasopit, Narumol, Zimmermann, Kathryn, Schrlau, Jill, Arey, Janet, Atkinson, Roger, Yu, Tian-Wei, Dashwood, Roderick H., Tao, Shu, and Simonich, Staci L. Massey
Abstract:: The heterogeneous reactions of ambient particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs (NPAHs) with NO₃/N₂O₅, OH radicals, and O₃ were studied in a laboratory photochemical chamber. Ambient PM[subscript 2.5] and PM₁₀ samples were collected from Beijing, China and Riverside, California, and exposed under simulated atmospheric long-range transport conditions...

Determination of Parent and Hydroxy PAHs in Personal PM₂.₅ and Urine Samples Collected During Native American Fish Smoking Activities

Creator:: Motorykin, Oleksii, Schrlau, Jill, Jia, Yuling, Harper, Barbara, Harris, Stuart, Harding, Anna, Stone, David, Kile, Molly, Sudakin, Daniel, and Simonich, Staci L. Massey
Abstract:: A method was developed for the measurement of 19 parent PAHs (PAHs) and 34 hydroxylated PAHs (OH-PAHs) in urine and personal air samples of particulate matter less than 2.5 um in diameter (PM[subscript 2.5]) using GC-MS and validated using NIST SRM 3672 (Organic Contaminants in Smoker’s Urine) and SRM 3673...

Prediction and Measurement of Polycyclic Aromatic Hydrocarbons (PAHs) Transformation Products in the Environment.

Creator:: Titaley, Ivan A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental contaminants consisting of fused benzene rings. Parent-PAHs, methylated-PAHs (MPAHs), and PAHs with molecular weight of 302 a.m.u (MW302-PAHs) are considered as unsubstituted-PAHs. These unsubstituted-PAHs undergo transformation reactions resulting in the formation of PAH-transformation products (PAH-TPs), or substituted-PAHs, including nitrated-, oxygenated-, and...
