Journal ArticleDOI
Geospatial association between adverse birth outcomes and arsenic in groundwater in New Hampshire, USA
Xun Shi,Joseph D. Ayotte,Akikazu Onda,Stephanie I Miller,Judy R. Rees,Diane Gilbert-Diamond,Tracy Onega,Jiang Gui,Margaret R. Karagas,John B. Moeschler +9 more
TL;DR: Generally, preterm birth has a stronger spatial association with groundwater arsenic than term LBW, suggesting an inconsistency in the impact of arsenic on the two reproductive outcomes, as well as evident spatial associations between the two adverse human reproductive outcomes and groundwater arsenic in New Hampshire, USA.
Journal ArticleDOI
Ingested nitrate and nitrite and bladder cancer in Northern New England.
Kathryn Hughes Barry,Rena R. Jones,Kenneth P. Cantor,Laura E. Beane Freeman,David C. Wheeler,Dalsu Baris,Alison Johnson,G. M. Monawar Hosain,Molly Schwenn,Han Zhang,Rashmi Sinha,Stella Koutros,Margaret R. Karagas,Debra T. Silverman,Mary H. Ward +14 more
TL;DR: The results suggest the importance of both drinking water and dietary nitrate sources as risk factors for bladder cancer.
Journal ArticleDOI
Infants' dietary arsenic exposure during transition to solid food.
Antonio J. Signes-Pastor,Kathryn L. Cottingham,Manus Carey,Vicki Sayarath,Thomas J. Palys,Andrew A. Meharg,Carol L. Folt,Carol L. Folt,Margaret R. Karagas +8 more
TL;DR: The observed increases in urinary arsenic concentrations likely indicate increased exposure to i-As during the transition to solid foods, suggests the need to minimize exposure during this critical period of development.
Journal ArticleDOI
Chronic Diseases Requiring Hospitalization and Risk of Non-Melanoma Skin Cancers—A Population Based Study from Denmark
Annette Østergaard Jensen,Annette Østergaard Jensen,Anne Braae Olesen,Claus Dethlefsen,Henrik Toft Sørensen,Margaret R. Karagas +5 more
TL;DR: This study supports the presence of an association between certain chronic diseases and NMSC, and suggests that these results unlikely are due to bias.
Journal ArticleDOI
The study of human nails as an intake monitor for arsenic using neutron activation analysis
T. A. Nichols,J. S. Morris,M. M. Mason,V. L. Spate,C. K. Baskett,T. P. Cheng,C. J. Tharp,J. A. Scott,T. L. Horsman,J. W. Colbert,A. E. Rawson,Margaret R. Karagas,Virginia Stannard +12 more
TL;DR: An irradiation position for the neutron activation analysis of nail specimens for arsenic is developed, in support of a case-control study involving New Hampshire residents consuming well water above the EPA Safe Drinking Water Standard of 0.050 ppm.
