Reducing Mercury Loads in The Cosumnes River

The Cosumnes River watershed has seasonal, non-point source hotspots for total mercury and methylmercury production, which discharge to the Sacramento-San Joaquin River Delta in north-central California. To reduce mercury loads to the Delta, researchers created open-water deep cells at the downstream end of wetlands.

Ospreys Benefit as Contaminants Decrease in Delaware Estuary

Lower levels of environmental contaminants—including pesticides, flame retardants and other pollutants—were recently found in osprey eggs in the Delaware Estuary compared to those tested from the 1970s through the early 2000s. 

USGS specializes in science at the environment-health interface, by characterizing the processes that affect the interaction among the physical environment, the living environment, and people, and the resulting factors that affect ecological and human exposure to disease agents.

Energy Science Team

The United States is one of the largest users of energy, consuming annually about one-quarter of the energy resources produced in the world. The energy industry and government regulators work to provide energy resources to the public safely and effectively. Management of energy byproducts such as waste materials (including both solid and liquid wastes) from oil and gas development are a...

Genomic and Behavioral Effects of the Neonicotinoid Imidacloprid in Birds Exposed Through Pesticide-Coated Seeds

The Challenge: Neonicotinoid pesticides act as agonists of nicotinic acetylcholine receptors (nAChRs) and are designed to be lethal to insects while theoretically posing little to no threat to vertebrates. The perceived safety of neonicotinoids has led to a sharp increase in their use in the United States and globally, since they were first introduced in 1994. The use of the neonicotinoid...

Assessing Toxicogenomics Effects of a Synthetic Androgen on Japanese Quail and the Development of an Avian Vitellogenesis Model

The Challenge: Endocrine active chemicals (EAC) are known to interfere with hormonally regulated physiological processes, thereby affecting signaling in the hypothalamic-pituitary-gonadal-liver (HPGL) axis and commonly resulting in reproductive dysfunction. Computational models that relate hormonal and genomic biomarkers within the HPGL axis to the reproductive cycle and ecologically relevant...

The Role of Japanese Quail in Ecotoxicology

The Challenge: Wild birds are exposed throughout their lives to natural and synthetic chemicals that are present in the environment, many of which interfere with the animal’s physiological and developmental systems. Relative concentrations, routes, frequency, and the environment in which chemical exposure occurs will determine to a large extent the bird’s response. Well-designed avian field...

Do Neonicotinoid Pesticide Seed Coatings Pose a Hazard to Seed-eating Birds?

The Challenge: Neonicotinoids are now the most widely applied class of insecticides in the United States, and are predominantly used in the form of seed treatments.

A Native Earthworm Accumulates Extraordinarily High Concentrations of Lead

The Challenge: As a rule, plants and animals contain lower concentrations of lead than are present in soils that support them. Lead does not biomagnify along trophic levels in ecosystems but instead remains relatively immobile in soil. The exposure of wildlife to soil lead depends mainly on the incidental ingestion of soil. The native earthworm, Eisenoides lonnbergi, is anomalous in its...
