Kelly Smalling
I am interested in the exposure and effects of contaminants including current-use pesticides and other endocrine active compounds on fish and wildlife with a focus on amphibian populations.
I am an environmental organic chemist who has been working with the USGS since 2004. My current research focuses on the occurrence, fate and effects of emerging contaminants including current-use pesticides in the environment. I am the lead for the Amphibian Research and Monitoring Initiative's Contaminants Project, the project coordinator of the "EDC effects on fish and wildlife in the Cheseapeake Bay Watershed" project through the Contaminants Biology Program, and a member of the Toxic Substances Hydrology Program's Pesticide Fate Research Team.
Education and Certifications
BS in Chemistry from the University of Alabama in Huntsville in 1999
MSPH in Environmental Health Science from the University of South Carolina in 2003
Science and Products
Estrogen equivalents of surface water and smallmouth bass estrogenic biomarker data in New Jersey, 2016-2017
Nutrients, estrogenicity, and fecal indicators in surface water collected from wetlands in the Klamath Marsh National Wildlife Refuge, Oregon, 2017-2018
Chloride in water, metals in sediment and amphibian tissues and amphibian capture information from wetlands in the Williston Basin of Montana and North Dakota, 2015-2017
Current-use pesticides and emerging amphibian pathogens in natural ponds, excavated ponds, and stormwater basins from 24 sites varying in land-use classifications throughout the New Jersey Pinelands, 2014-2016
Amphibian Occupancy and Effects of Habitat Use on Pesticide Exposure in Iowa Wetlands
Hormone, pesticide, pharmaceutical and other organic compound data for select water and bed sediment samples collected in Chesapeake Bay watershed in parts of Maryland, Pennsylvania, Virginia, and West Virginia, 2006-2014
Widespread Legacy Brine Contamination from Oil Shales Reduces Survival of Chorus Frog Larvae-Data
Site- and individual-level contaminations affect infection prevalence of an emerging infectious disease of amphibians
Food, beverage, and feedstock processing facility wastewater: A unique and underappreciated source of contaminants to U.S. streams
The statistical power to detect regional temporal trends in riverine contaminants in the Chesapeake Bay Watershed, USA
Integrated science for the study of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in the environment—A strategic science vision for the U.S. Geological Survey
Juvenile African clawed frogs (Xenopus laevis) express growth, metamorphosis, mortality, gene expression, and metabolic changes when exposed to thiamethoxam and clothianidin
Assessing the ecological functionality and integrity of natural ponds, excavated ponds and stormwater basins for conserving amphibian diversity
Metal accumulation varies with life history, size, and development of larval amphibians
Pilot-scale expanded assessment of inorganic and organic tapwater exposures and predicted effects in Puerto Rico, USA
Reconnaissance of cumulative risk of pesticides and pharmaceuticals in Great Smoky Mountains National Park streams
Public and private tapwater: Comparative analysis of contaminant exposure and potential risk, Cape Cod, Massachusetts, USA
Environmental and anthropogenic drivers of contaminants in agricultural watersheds with implications for land management
Multi-region assessment of chemical mixture exposures and predicted cumulative effects in USA wadeable urban/agriculture-gradient streams
Chemical-contaminant mixtures are widely reported in large stream reaches in urban/agriculture-developed watersheds, but mixture compositions and aggregate biological effects are less well understood in corresponding smaller headwaters, which comprise most of stream length, riparian connectivity, and spatial biodiversity. During 2014–2017, the U.S. Geological Survey (USGS) measured 389 unique orga
