Study Provides a Data Resource for Per- and Polyfluoroalkyl Substances in Streams Within Iowa Agricultural Watersheds

Per- and poly fl uoroalkyl substances (PFAS) were detected in streams within agricultural areas (an often-unmeasured landscape) across Iowa. The data from this study provide one resource to understand the extent of PFAS concentrations in water resources from diverse landscapes throughout the United States.

Science to Understand Low-Level Exposures to Neonicotinoid Pesticides, their Metabolites, and Chlorinated Byproducts in Drinking Water

Scientists reported the discovery of three neonicotinoid pesticides in drinking water and their potential for transformation and removal during water treatment. The research provides new insights into the persistence of neonicotinoids and their potential for transformation during water treatment and distribution, while also identifying granulated activated carbon as a potentially effective...

Can Spills from Swine Lagoons Result in Downstream Health Hazards?

Livestock manure spills have been shown to result from events such as equipment failures, over-application of manure to agricultural fields, runoff from open feedlots, storage overflow, accidents with manure transporting equipment, and severe weather. Our specialized teams of hydrologists, chemists, biologists and geologists, in collaboration with Johns Hopkins Bloomberg School of Public Health...

Food Resources Lifecycle Integrated Science Team

The team studies the movement of toxicants and pathogens that could originate from the growing, raising, and processing/manufacturing of plant and animal products through the environment where exposure can occur. This information is used to understand if there are adverse effects upon exposure and to develop decision tools to protect health.

Endocrine Disrupting Compounds in the Chesapeake Bay Watershed Science Team

The Chesapeake Bay is the largest estuary in the United States and provides critical resources to fish, wildlife and people. For more than a decade, recreational fish species have been plagued with skin lesions and intersex conditions (the presence of male and female sex characteristics in the same fish) that biologists attributed to exposures to endocrine disrupting chemicals (EDCs)...

Native Bees are Exposed to Neonicotinoids and Other Pesticides

A recent reconnaissance study by the U.S. Geological Survey (USGS) demonstrates the first observed occurrence of pesticides, including neonicotinoid insecticides, in wild-caught native bees. The results indicate that native bees collected in an agricultural landscape are exposed to multiple pesticides including insecticides, fungicides, and herbicides. This reconnaissance study is the first step...
