Toxins and Harmful Algal Blooms Science Team

The team develops advanced methods to study factors driving algal toxin production, how and where wildlife or humans are exposed to toxins, and ecotoxicology. That information is used to develop decision tools to understand if ​ toxin exposure leads to adverse health effects in order to protect human and wildlife health.

Immunomodulation Science Team

The Immunomodulation Integrated Science Team focuses on contaminant and pathogen exposures in the environment that might influence the immune systems of wildlife and the connection to their shared environment with humans. In collaboration with public-health officials, the Team also addresses potential human-health risks stemming from similar exposures. If actual risks are identified, this Team...

Satellite Data Used to Estimate and Rank Cyanobacterial Bloom Magnitude in Florida and Ohio Lakes—Developing Tools to Protect Human and Wildlife Health from Cyanotoxin Exposure

Cyanobacterial bloom magnitude during 2003–11 was quantified and ranked in Florida and Ohio lakes with a newly developed modelling tool that allows for the use of multiple satellite data sources and user-defined thresholds. This tool was designed to identify the magnitude of algal blooms, but one metric alone cannot adequately represent the severity of a bloom of interest in terms of toxicity. The...

Mixtures of Algal Toxins Present Prior to and After Formation of Visible Algal Blooms—Science to Inform the Timing of Algal Toxin Exposure

Cyanobacteria with toxin-producing potential, genes indicating an ability for toxin synthesis, or cyanotoxins were present before and after formation of a visible algal bloom in Kabetogama Lake, a popular recreation area in Voyageurs National Park that lies along the border of Minnesota and Canada. The temporal patterns observed in this study indicate that sampling only when there is a visible...

Can There be Unintended Benefits when Wastewater Treatment Infrastructure is Upgraded?

Science from the U.S. Geological Survey (USGS) and other entities has shown that a mixture of natural and synthetic estrogens and other similar chemicals are discharged from wastewater treatment plants (WWTPs) to streams and rivers.

Are Naturally Occurring Algal Toxins in Water Resources a Health Hazard?

A growing number of human gastrointestinal, respiratory, dermatologic, and neurologic effects, as well as dog and livestock illnesses and deaths, in the United States have been linked to exposures to algal blooms in recreational lakes and stock ponds. Some of the blooms contain cyanobacteria, which have the potential to produce cyanotoxins in freshwater systems. However, the connection between...

What is the Chemical and Microbial Content of Our Tap Waters?

Safe Drinking Water Act compliance addresses the safety of public-supply water systems. The composition of public-supply drinking water is generally only tested at the treatment facility, and not at the tap in homes and businesses after traveling through the water distribution system. Only lead and copper are tested at a subset of residential and other taps. Testing of water in private wells is...

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.
