We are pleased to announce the latest article by the staff of our Institute, published in the renowned journal Water:
Gebus-Czupyt B., Chmiel S., Kończak M., Huber M., Stienss J., Radzikowska M., Stępniewski K., Pliżga M., Zielińska B., 2024. The Isotopic Composition of Selected Phosphate Sources (δ18O-PO4) from the Area of the Vistula and Bug Interfluve (Poland). Water 16, no. 19: 2809. https://doi.org/10.3390/w16192809
The study presents new data on δ¹⁸O values in dissolved inorganic phosphates (PO₄) extracted from various types of water from the Lublin Upland and Roztocze regions, as well as selected phosphate-bearing rock samples from this area. Preliminary results revealed slightly varying ranges of δ¹⁸O-PO₄ values in spring, river, and drainage waters, wastewater from treatment plants, and bedrock samples. This suggests that the isotopic composition of oxygen can be a useful tool for identifying the sources of phosphorus in water. However, unlike other key environmental elements such as carbon (C), nitrogen (N), or sulfur (S), phosphates provide only one marker, making it particularly important to thoroughly identify potential local sources of phosphorus.
Further research is underway to evaluate the contribution of phosphates leached from sedimentary rocks to groundwater and surface runoff in the area and, consequently, their role in eutrophication processes.
These studies were founded by the Polish National Science Centre (grant no. UMO-2020/37/B/ST10/01994).
