Sutapa Ghosal,John C. Hemminger,Hendrik Bluhm,Bongjin Simon Mun,Eleonore L. D. Hebenstreit,Guido Ketteler,D. Frank Ogletree,Félix G. Requejo,Félix G. Requejo,Miquel Salmeron +9 more
TL;DR: Using x-ray photoelectron spectroscopy operating at near ambient pressure, this paper measured the composition of the liquid/vapor interface for deliquesced samples of potassium bromide and potassium iodide.
Journal ArticleDOI
Microplastics in four estuarine rivers in the Chesapeake Bay, U.S.A.
Lance T. Yonkos,Elizabeth A. Friedel,Ana C Perez-Reyes,Sutapa Ghosal,Courtney Arthur,Courtney Arthur +5 more
TL;DR: Concentrations demonstrated statistically significant positive correlations with population density and proportion of urban/suburban development within watersheds and vary temporally in response to weather phenomena such as storm events.
Journal ArticleDOI

TL;DR: In this paper, the application of synchrotron-based spectroscopies and microscopies to environmentally relevant samples is presented. But the experiments were performed at the molecular environmental science beamline (11.0.2) at the Advanced Light Source, Lawrence Berkeley National Laboratory.
Journal ArticleDOI
SEM/EDS and optical microscopy analyses of microplastics in ocean trawl and fish guts
TL;DR: Particle morphology determined by optical microscopy and SEM suggests the fish ingested particles contained both degradation fragments from larger plastic pieces and also manufactured microplastics, as well as pigment particles consistent with manufactured materials.
Journal ArticleDOI
Novel method for the extraction and identification of microplastics in ocean trawl and fish gut matrices
Jeff Wagner,Zhong-Min Wang,Sutapa Ghosal,Chelsea M. Rochman,Chelsea M. Rochman,Margy Gassel,Stephen Wall +6 more
TL;DR: In this article, an ultrasonic extraction with ultrapure water was used to remove microplastic from fish stomachs without dissolving the stomach tissues or microplastics, which minimizes issues with hazardous disposal and laboratory safety.
