“…For example, the input of N runoff derived from the use of inorganic fertilizers and agricultural development leads to the presence of elevated δ 15 N (between −4 to +4‰) values in the water bodies 71,73,74 . Nitrate concentrations from manure measured in Brittany (France) were reported to exhibit a positive correlation with elevated δ 15 N values 75 .…”

Human activities have profoundly altered the global nutrient cycle through Land Use and cover Changes (LUCCs) since the industrial revolution and especially during the Great Acceleration (1950 CE). Yet, the impact of such activities on terrestrial and aquatic ecosystems above their ecological baselines are not well known, especially when considering the response of these systems to the intensity of LUCCs on nutrient cycles. Here, we used a multiproxy approach (sedimentological, geochemical and isotopic analyses, historical records, climate data, and satellite images) to evaluate the role that LUCCs have on nitrogen (n) cycling in a coastal mediterranean watershed system of central chile over the last two centuries. Despite long-term anthropogenic use (agriculture, cattle grazing) in the Matanzas watershed-lake system, these LUCC appear to have had little impact on nutrient and organic matter transfer since the Spanish Colonial period. In contrast, the largest changes in N dynamics occurred in the mid-1970s, driven by the replacement of native forests and grasslands by government-subsidized tree plantations of introduced Monterey pine (Pinus radiata) and eucalyptus (Eucalyptus globulus). These LUCC had major impacts on the transfer of organic matter (which increased by 9.4%) and nutrients (as revealed by an increase in total N) to Laguna Matanzas. Our study shows that the presence of anthropogenic land use/cover changes do not necessarily alter nutrient supply and n availability per se but rather it is the magnitude and intensity of such changes that produce major impact on these processes in these mediterranean watersheds.

“…Core P4 is located close to the main tributary Matica which represents the most important sources of water and terrigenous material for the Plitvice Lakes system. Previous investigations have shown that surrounding source rocks (dolomites with small amounts of quartz and aluminosilicates) and soils are the main source of materials in sediments at locations P4, while the share of these minerals is low in sediments at location P1, where a signi cant amount of calcite was determined (Horvatinčić et al 2017). Calcite was also the dominant mineral phase in the sediments where terrigenous input is small (the Lake Kozjak), or negligible (the Lake Kaluđerovac) (Horvatinčić et al 2014(Horvatinčić et al , 2107.…”

Sediments from the Plitvice Lakes (Horvatinčić et al 2008(Horvatinčić et al , 2014(Horvatinčić et al , 2017 and the Lake Visovac (Mikac et al 2017) were previously dated, enabling estimation of the historical trends of anthropogenic impacts of TCE for these lakes. In order to determine elements Te, Ga, Ge and Nb, which we previously did not measure, we have validated the method for their determination by HR ICP-MS technique, with enough high sensitivity to detect low levels of TCE expected in the carbonate-rich sediments of these environments.…”

The appearance and vertical distribution of technology-critical elements (TCE) such as Li, Nb, Sc, Ga, Y, La, Sb, Ge, Te, and W were investigated in sediment cores taken in pristine freshwater and marine lakes located within protected areas of Croatia (Plitvice Lakes, Visovac Lake, and Mir Lake). These lake systems are isolated from the direct impact of human activities, and accordingly, the geochemical research in such environments may help to assess temporal trends in historical deposition of anthropogenic TCE. The analytical method of choice in determining the concentration of TCEs was High resolution inductively coupled plasma - mass spectrometry (HR ICP-MS). The results obtained have shown that the measured TCE spanned with wide ranges of concentrations, as a result of the different input of terrigenous material into the investigated lake systems which is further diluted by the formation of authigenic and biogenic carbonates. Evaluation of the anthropogenic impact on TCE levels showed low enrichment of Sb and Te in the upper sediment layers of the Mir Lake and the Plitvice Lakes. Despite that, concentrations of investigated TCE were low, compared to results described in the literature, indicating that the investigated remote lakes can be considered uncontaminated with these elements.

“…The main aim of the investigation of the group from the Ruder Bošković Institute was the study of secondary carbonate precipitation in the form of tufa and lake sediment (e.g., [7,31,32]), which made the Plitvice Lakes a unique natural phenomenon. The analysis of more than 30 years of records of various physico-chemical parameters presented geochemical conditions for tufa precipitation in relation to climate change [33].…”

The application of tritium, 2H, and 18O in the characterization of the precipitation, groundwater, and surface and lake water of the Plitvice Lakes (PL), Croatia, over the 1979–2019 period is presented. An increase in the mean annual air temperature of 0.06 °C/year and in the annual precipitation amount of 10 mm/year is observed. The good correlation of the tritium activity concentration in the PL and Zagreb precipitation implies that the tritium data for Zagreb are applicable for the study of the PL area. The best local meteoric water line at PL was obtained by the reduced major axis regression (RMA) and precipitation-weighted ordinary least squares regression (PWLSR) approaches: δ2HPWLSR = (7.97 ± 0.12) δ18O + (13.8 ± 1.3). The higher deuterium excess at PL (14.0 ± 2.2 ‰) than that at Zagreb reflects the higher altitude and influence of the Mediterranean precipitation. The δ2H in precipitation ranges from −132.4‰ to −22.3‰ and δ18O from −18.3 ‰ to −4.1‰. The much narrower ranges in the groundwater (<1‰ in δ18O, <10‰ in δ2H) indicate the good mixing of waters in aquifers and short mean residence times. The higher average δ2H in all three karst springs observed after 2003 can be attributed to the increase in the mean air temperature. The mean δ2H and δ18O values in the surface and lake water increase downstream due to the evaporation of surface waters. There is no significant difference between the surface water line and the lake water line (2011–2014). The stable isotope composition of the surface and lake waters reacts to extreme hydrological conditions.
