Mission Areas

Environmental Health

The Toxic Substances Hydrology and Contaminant Biology Programs work collaboratively to assess and differentiate the environmental contaminant and pathogen exposures that cause actual health risks versus those that are only perceived. Specialized teams of hydrologists, geologists, chemists, biologists, and geographers work together in the field and laboratories across the United States.

Standardized guide to the examination and necropsy of the horseshoe crab using Limulus polyphemus as Limulidae prototype

The Atlantic, or American, horseshoe crab (Limulus polyphemus) has existed largely unchanged for over 100 million years. Millions of individuals are commonly observed ashore in spring and summer months during spawning events along the entire North American coastline expanding from the East to the Gulf coasts of the United States and Mexico. Other...

Malignant melanoma of Brown Bullhead (Ameiurus nebulosus) in Lake Memphremagog, Vermont/Quebec

In 2012, brown bullhead (Ameiurus nebulosus) with large, raised, black growths were first reported from multiple areas within the Vermont portion of Lake Memphremagog. Subsequent surveys conducted from 2014 to 2017 at two sites within the lake indicated a prevalence of 30% in adult brown bullhead 200 mm and above total length. These lesions...
