Featured Works

Characterization of Per- and Polyfluorinated Alkyl Substances Present in Commercial Anti-fog Products and Their In Vitro Adipogenic Activity.

Journal article Environmental science & technology · January 2022 Featured Publication Anti-fog sprays and solutions are used on eyeglasses to minimize the condensation of water vapor, particularly while wearing a mask. Given their water-repellent properties, we sought to characterize per- and polyfluorinated alkyl substance (PFAS) compounds ... Full text Cite

Characterizing azobenzene disperse dyes in commercial mixtures and children's polyester clothing.

Journal article Environmental pollution (Barking, Essex : 1987) · October 2021 Featured Publication Azobenzene disperse dyes are the fastest-growing class of dyestuffs, yet little is known about dye occurrences, sources, and transformations; azo dyes are also underrepresented in chemical standard catalogs, molecular databases, and mass spectral libraries ...

Influence of CNT loading and environmental stressors on leaching of polymer-associated chemicals from epoxy and polycarbonate nanocomposites

Journal article Environmental Chemistry · September 1, 2021 Featured Publication Abstract: Nanoparticles such as carbon nanotubes are increasingly added to polymer matrices to improve tensile strength and electrical and thermal conductivity, and to reduce gas permeability. During use and after disposal, these plastic nanocomposites (PN ... Full text Open Access Cite

Development of a sensitive direct injection LC-MS/MS method for the detection of glyphosate and aminomethylphosphonic acid (AMPA) in hard waters.

Journal article Analytical and bioanalytical chemistry · June 2021 Featured Publication Glyphosate is currently the most widely used herbicide in the world; however, the zwitterionic and highly polar properties of glyphosate make current pesticide analysis methods unsuitable for its trace analysis in natural waters. Additionally, current glyp ... Full text Open Access Cite

High-Throughput Trace-Level Suspect Screening for Per- and Polyfluoroalkyl Substances in Environmental Waters by Peak-Focusing Online Solid Phase Extraction and High-Resolution Mass Spectrometry

Journal article ACS ES&T Water · April 8, 2021 Featured Publication Per- and polyfluoroalkyl substances (PFASs) occur widely in environmental waters. PFAS risk assessment necessitates the identification of unanticipated PFASs at trace levels and therefore requires determinative methods with nanogram per liter detection lim ...

Assessment of emerging polar organic pollutants linked to contaminant pathways within an urban estuary using non-targeted analysis.

Journal article Environmental science. Processes & impacts · March 2021 Featured Publication A comprehensive, non-targeted analysis of polar organic pollutants using high resolution/accurate mass (HR/AM) mass spectrometry approaches has been applied to water samples from San Francisco (SF) Bay, a major urban estuary on the western coast of the Uni ...

Structure Database and In Silico Spectral Library for Comprehensive Suspect Screening of Per- and Polyfluoroalkyl Substances (PFASs) in Environmental Media by High-resolution Mass Spectrometry.

Journal article Analytical chemistry · February 2021 Featured Publication Per and polyfluoroalkyl substances (PFASs) are an important class of organic pollutants. Many diverse PFASs are used in commerce and most are not amenable to conventional targeted chemical analysis due to lack of reference standards. Therefore, methods for ... Full text Cite

Analysis of Single-Walled Carbon Nanotubes in Estuarine Sediments by Density Gradient Ultracentrifugation Coupled to Near-Infrared Fluorescence Spectroscopy Reveals Disassociation of Residual Metal Catalyst Nanoparticles.

Journal article Environmental science & technology · January 2021 Featured Publication The continued growth of the nanotechnology industry and the incorporation of nanomaterials into consumer applications will inevitably lead to their release into environmental systems. Single-walled carbon nanotubes (SWCNTs) in particular have exhibited man ... Full text Cite

Illuminating the exposome with high-resolution accurate-mass mass spectrometry and nontargeted analysis

Journal article Current Opinion in Environmental Science and Health · June 1, 2020 Featured Publication Exposomics seeks a comprehensive understanding of the links between human health and environmental chemical exposures. Analytical chemistry tools capable of identifying low-level organic contaminants in complex environmental samples are needed to meet the ... Full text Cite
