معرفی
Dr. Lance Yonkos is an Associate Professor in the Department of Environmental Science & Technology at the University of Maryland, College Park. He is affiliated with the College of Agriculture and Natural Resources and conducts research focused on contaminant abundance, transport, and toxicological effects in aquatic environments. His work integrates laboratory and field studies to investigate microplastic pollution, endocrine disruptors, and contaminant sources in the Chesapeake Bay watershed.
Yonkos' research emphasizes:
- Microplastic dynamics in surface waters and sediments, particularly linked to land use patterns
- Development of non-lethal sampling methods for fish populations
- Environmental mitigation strategies for coal ash and poultry manure management
- Identification of PCB sources in the Anacostia River using passive samplers and mussel monitoring
His studies often combine advanced analytical techniques like mass spectrometry with ecological field observations to assess pollutant impacts on aquatic organisms. Key themes include:
- Endocrine disruption effects in fish (e.g., testicular oocytes in bass)
- Fate and toxicity of pharmaceuticals and personal care products
- Contaminant sorption to microplastics
- Ecological risk assessment of Chesapeake Bay ecosystems
Recent publication trends focus on:
- PCB contamination in urban watersheds
- Microplastic-soil interactions in wetlands
- Effects of emerging contaminants on fish reproduction
- Development of biomarkers for estrogenic exposure
No scientific awards or grants are explicitly mentioned in the provided materials. His research group collaborates on field deployments of freshwater mussels and maintains an active presence in environmental monitoring initiatives across Maryland's waterways.
