Oceans, human health, climate change focus of unique new $5.7 million alliance

UMCES one of five institutions participating in new center to protect public

The University of Maryland Center for Environmental Science is part of new multi-academic center to study the effects of ocean health-related illness and the interactions from climate change. The Center for Oceans and Human Health and Climate Change Interactions, funded by a $5.7 million grant from the National Institute of Environmental Health Sciences (NIEHS), will be headquartered at the University of South Carolina Arnold School of Public Health and involve more than 20 researchers from five colleges and universities, including the University of South Carolina, The College of Charleston, The Citadel, Baylor University, and the University of Maryland Center for Environmental Science.

Climate change-related factors may enhance the presence of disease-causing Vibrio bacteria and harmful algal blooms, and their production of toxins that are harmful to fish, marine mammals and humans.

The Center’s main purpose will be to assess the effects of illness and disease related to ocean health, to then use the information to develop forecasts that prevent human exposure to these stressors, and other prevention strategies. In particular, the scientists aim to look at climate change-related factors that may enhance the presence of disease-causing Vibrio bacteria and harmful algal blooms, and their production of toxins that are harmful to fish, marine mammals and humans.

"Understanding and addressing the health impacts to communities associated with the rapid changes in climate requires a team of scientists that cross a diverse range of traditional scientific disciplines. The University of Maryland Center for Environmental Science is pleased to  collaborate with our peers across the country to bring scientists together with the communities they serve to understand the impact of climate change on health and disease," said UMCES President Peter Goodwin.

The Center will be led by Geoffrey I. Scott, clinical professor and chair in the USC Department of Environmental Health Sciences, and deputy director Paul A. Sandifer, director of the Center for Coastal Environmental and Human Health at the College of Charleston, who will work with a team of scientists who are faculty leaders at all five institutions. Additionally, researchers and environmental public health practitioners from the National Oceanic and Atmospheric Administration, the U.S. Geological Survey, the Interstate Shellfish Sanitation Conference, and the Lowcountry Alliance for Model Communities will participate.

“Elevated levels of dangerous Vibrio bacteria and harmful algal blooms toxins can adversely affect human health by increasing human exposure in drinking water, seafood and in surface waters used for recreation,” said Scott. “By establishing predictive water quality and environmental variables, we can develop models and early warning forecasts to alert the public, prevent exposure and thus better protect ecosystem and human health.”

Heath Kelsey of the University of Maryland Center for Environmental Science will be part of the Center focused on community engagement, facilitating communication amongst the researchers and the communities. Kelsey has been facilitating conversations at the intersection of science, community, and the environment around the world with the UMCES' Integration and Application Network, which works with communities to develop scientific report cards to monitor progress on environmental restoration projects.

“Because we have the scientific and public health background, we have the ability to facilitate these stakeholder meetings and the process of engaging folks in science that are not scientists,” he said. “This is a great example of bringing science to underserved populations and making sure that scientific results are incorporated into future management plans, particularly the impact of climate change on coastal communities.”

Working against time for everyone

The intersection of climate change and urbanization is nowhere more apparent than in the coastal zone, as increasing global temperatures, sea level rise, and coastal flooding meet growing population centers and economic hubs in coastal communities in South Carolina, the United States and the world.

Common coastal ecosystem problems include:

  • Increased frequencies and severities of  harmful algal blooms, water-based plants that can grow out of control and produce potent toxins that can impact human and animal health;
  • Antibiotic resistance in disease-causing microbes such as Vibrio bacteria, that live in coastal waters and can cause harmful infections through the consumption of raw/undercooked shellfish and wound infections;
  • Contaminants of emerging concern such as microplastics in coastal waters resulting from trash and tire decomposition;
  • Pharmaceutical and personal care product contamination from discharges into sewer systems including byproducts of human use, metabolism and disposal of expired medicines.

Scientists at the University of South Carolina will assess impacts of increased exposure to climate stressors (rising temperatures and changing salinities) on associated diseases and illness, such as Vibrio bacteria in seafood and wound infections, and on harmful algal bloom toxin effects non-alcoholic fatty liver disease. These analyses will indicate the extent and magnitude that climate change may have on these illnesses under future climate scenarios. This will be used to better identify vulnerable populations and help tailor community-engagement activities for these susceptible communities.

“With more than 50 percent of the southeastern U.S. population now living within 50 miles of the seashore, we are long overdue to have this kind of public health research center available to the citizens of South Carolina and beyond,” said Thomas Chandler, dean of the Arnold School of Public Health at USC.

Co-investigators at USC include Sean Norman, Alan Decho, Jamie Lead, Saurabh Chatterjee, Shuo Xiao, Dwayne Porter (USC Environmental Health Sciences), Bo Cai (USC Epidemiology and Biostatistics), Daniela Friedman (USC Health Promotion, Education, and Behavior), and John Ferry, Tim Shaw, Susan Richardson (USC Chemistry). Bryan Brooks, Thad Scott, and Scott James of Baylor University will lead the research on Harmful Algal BloomsJohn Weinstein of the Department of Biology at the Citadel will lead the research on the environmental health effects of microplastics. Heath Kelsey of the University of Maryland Center for Environmental Science will be part of the Center focused on community engagement, facilitating communication amongst the researchers and communities.
