Analysis and Monitoring of Algal Toxins in Fresh and Coastal/Estuarine Environments

Mash, H. Analysis and Monitoring of Algal Toxins in Fresh and Coastal/Estuarine Environments. Presented at USEPA Small Systems Workshop, Cincinnati, OH, August 22 - 24, 2017.
Impact/Purpose:
Several factors contribute to the increased frequency and magnitude of harmful algal blooms (HABs). Elevated temperatures, changes in precipitation, population demographics, agricultural land use linked to nitrogen loading increases, and an aging water treatment infrastructure all combine to increase the probability of toxins being present in consumers’ tap water. Several notable HAB events have impacted a number of states. As a result of the human, ecological, and economic impacts of HABs, the U.S. EPA has established a research program to address issues related to the detection, quantification, and monitoring of algal blooms. This research has several objectives: develop new or refine existing chemical, instrumental, and biological methods for detection of HABs and their toxins; test such methods in field studies; determine method(s) best used as early warning systems for detection of HABs and their toxins. This presentation focuses on the non-targeted analysis of algal products by mass spectrometry, but will also summarize current research on other related HAB research projects.
