NORTH EAST, MD — Holly Adams, a sophomore at Cecil College, recently shared her groundbreaking research at the Society of Environmental Toxicology and Chemistry (SETAC) conference in Fort Worth, Texas. Her presentation focused on identifying sustainable alternatives to peat moss, a key material used in toxicology testing that has significant environmental consequences.
Peat moss, a critical carbon sink found in bogs, releases greenhouse gases like carbon dioxide when harvested—contributing to climate change. “My research follows a global initiative to explore whether alternatives to peat could be used in standard artificial soil without compromising the accuracy of environmental toxicology testing,” Adams explained.
Through her internship at the U.S. Army Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC), Adams examined straw and hay as potential peat replacements. Initial testing with earthworms, commonly used in toxicology studies, suggests straw could serve as a viable substitute. However, further research is required to confirm its suitability.
Adams, who is studying Biology with a concentration in Environmental Science and is set to graduate in May 2025, credits her mentors at DEVCOM CBC for their essential role in guiding her work. “The scientists at DEVCOM CBC have been instrumental in helping me refine my research and presentation,” she said.
Presenting at the SETAC conference allowed Adams to engage with environmental toxicology experts and spark meaningful discussions about her findings. “It was incredible to speak with professionals and experts who helped explore future applications for my research,” Adams noted. “I’m excited about the potential impact of finding sustainable alternatives to peat moss on global testing standards.”
Looking ahead, Adams plans to test additional organic materials and expand her research to include other soil organisms. Her ultimate goal is to contribute to environmental sustainability by reducing the industry’s reliance on peat moss for toxicology testing.
