Dr. Marianna Oláh - MATE Research
Overview
Dr. Marianna Oláh is a Research Fellow at the Division of Environmental Analysis within the Research Center for Agro-Environmental Sciences at the Institute of Environmental Sciences, Hungarian University of Agriculture and Life Sciences, Gödöllő, Hungary. Her research focuses on ecotoxicology and soil ecology, particularly the effects of agricultural pesticides on non-target soil organisms. She develops laboratory model systems to assess persistent compounds, applying biomarker-based approaches and studying mixture toxicity. She has authored 10 scientific papers (h-index: 5) and is a member of the Hungarian Society of Ecotoxicology.

Projects
2024-1.1.1-KKV_Fókusz-2024-00036, PFAS-free adaptive membranes for sustainable biological waste treatment
Industrial composting widely uses semi-permeable ePTFE membrane covers, but their production involves PFAS compounds (e.g., PFOS), posing environmental risks and facing EU restrictions. This project develops PFAS-free covers with validated environmental compliance, long-term durability, and optimized performance across diverse composting systems.https://palyazatok.uni-mate.hu/2024-1.1.1-kkv_f%C3%B3kusz-2024-00036
KKCS-9, 2024-2027 "Tracking the progress on ecosystem restoration involving agriculture-related Nature Based Solutions."
The research assesses regenerative grazing, covering soil, ecological, botanical, and parasitological aspects. Multi-year field studies at Bőszénfa deer farm, complemented by lab analyses, test short, intensive grazing followed by regeneration, aiming to improve pasture, support conservation, climate adaptation, and develop practical recommendations.
