Journal ArticleDOI
Unusual inflammatory and fibrogenic pulmonary responses to single-walled carbon nanotubes in mice
Anna A. Shvedova,Elena R. Kisin,Robert R. Mercer,Ashley R. Murray,Victor J. Johnson,Alla I. Potapovich,Yulia Y. Tyurina,Olga Gorelik,Sevaram Arepalli,Diane Schwegler-Berry,Ann F. Hubbs,James M. Antonini,Douglas E. Evans,Bon Ki Ku,Dawn Ramsey,Andrew D. Maynard,Valerian E. Kagan,Vincent Castranova,Vincent Castranova,Paul A. Baron +19 more
TL;DR: It is demonstrated that pharyngeal aspiration of SWCNT elicited unusual pulmonary effects in C57BL/6 mice that combined a robust but acute inflammation with early onset yet progressive fibrosis and granulomas and caused a significantly weaker pulmonary inflammation and damage.
Journal ArticleDOI
Sources and concentration of nanoparticles (<10 nm diameter) in the urban atmosphere
TL;DR: In this paper, the authors show that road traffic and stationary combustion sources generate a significant number of nanoparticles of diameter of 1.5 µm and 3 µm, respectively.
Journal ArticleDOI
Carbon nanotube dosimetry: from workplace exposure assessment to inhalation toxicology.
Aaron Erdely,Matthew M. Dahm,Bean T. Chen,Patti C. Zeidler-Erdely,Joseph E. Fernback,M. Eileen Birch,Douglas E. Evans,Michael L. Kashon,James A. Deddens,Tracy Hulderman,Suzan A. Bilgesu,Lori A. Battelli,Diane Schwegler-Berry,Howard D. Leonard,Walter McKinney,David G. Frazer,James M. Antonini,Dale W. Porter,Vincent Castranova,Mary K. Schubauer-Berigan +19 more
TL;DR: These findings showed a limited pulmonary inflammatory potential of MWCNT at levels corresponding to the average inhalable elemental carbon concentrations observed in U.S. CNT facilities and estimates suggest considerable years of exposure are necessary for significant pathology to occur at that level.
Journal ArticleDOI
Occupational Exposure Assessment in Carbon Nanotube and Nanofiber Primary and Secondary Manufacturers
Matthew M. Dahm,Douglas E. Evans,Mary K. Schubauer-Berigan,M. Eileen Birch,Joseph E. Fernback +4 more
TL;DR: CNT/CNF concentrations were above the proposed NIOSH REL for PBZ samples in two secondary manufacturing facilities that use these materials for commercial applications.
Journal ArticleDOI
Identification and characterization of potential sources of worker exposure to carbon nanofibers during polymer composite laboratory operations.
Lawrence F. Mazzuckelli,Mark M. Methner,M. Eileen Birch,Douglas E. Evans,Bon-Ki Ku,Keith G. Crouch,Mark D. Hoover +6 more
TL;DR: The goal of this study was to examine various operations involved in the handling or processing of CNF materials and to determine whether emission of these materials occurred.
