“…The results of this study indicate that access to the examined lakes should be limited (Figures 9 and 10). Tourist infrastructure in the evaluated trail segments should be upgraded, for example by introducing barriers to separate visitors from the lakes (segments number 2, 3,4,5,6,11,14,16,17,18,24,26) and by eliminating lake access points and illegal paths (segments number 1,7,8,9,10,12,13,15,25,28,29,30,31, and an illegal path south of Lake Zadni Staw Polski) (Figure 7). the studied lakes, and wastewater should be directed to the existing wastewater treatment plant at the shelter.…”

“…Mountain areas are characterized by high biodiversity and attractive landscapes, and they are popular tourist sites. The above contributes to the development of tourism infrastructure, and it increases tourist traffic, which intensifies the usually negative effects of anthropopressure on mountain ecosystems, including aquatic ecosystems [8][9][10][11][12][13][14]. Global tourism interest also leads to a phenomenon called "overturism" (it occurs when there are too many visitors to a particular destination in some places.…”

Eutrophication is one of the major threats to the quality of water in high mountain lakes. The inflow of elements having biological origin may significantly aggravate the ecological status of those ecosystems. For this reason, the aim of this study was to map and assess the impact of anthropogenic pressure on alpine lakes in the valley of Dolina Pięciu Stawów Polskich (known in English as the Valley of Five Polish Lakes) in the Tatra National Park in Poland. The effects of tourism and easy access to alpine lakes on changes in their ecological status were determined. Tourist trails were evaluated based on the difficulty of access to the water surface of analyzed alpine lakes, with a method developed for assessing anthropogenic pressure on aquatic ecosystems. The method, deployed for the first time in 2019, was modified and adapted to the local environmental conditions in the research area. The results of this study indicate that tourism pressure contributes to the growth of submerged vegetation in alpine lakes. The presence of aquatic plants (including vascular plants) shows ecosystem response to water enrichment with biogenic substances. The present findings were used to formulate practical recommendations and propose modifications to the evaluated hiking trails. The research method developed in the study can support analysis and control of tourist traffic, thus reducing anthropogenic pressure on alpine lakes in national parks located in mountain areas.

“…However, palaeolimnological research has become more extensive over the last years in Slovakia (e.g. Hamerlík et al 2016;Bitušík et al 2018) and there is the tendency to quantitatively reconstruct Holocene temperature patterns in the Western Carpathians.…”

Here we present a summary of subfossil chironomids (Diptera: Chironomidae) found in the surface sediments of 52 Tatra Mts. lakes (Slovakia, Poland). Head capsules of 73 morphotypes of 5 subfamilies are described and illustrated. In addition to the previously documented subfossils by Brooks et al. (2007), we present 15 new morphotypes: Diamesa Tatra-type A, Diamesa Tatra-type B, Pseudodiamesa branickii-type, Pseudodiamesa nivosa-type, Pseudokiefferiella parva, Brillia bifida-type, Cricotopus (Paratrichocladius) skirwithensis-type, Cricotopus (Cricotopus) tremulus-type, Cricotopus/Orthocladius I, Eukiefferiella brevicalcar-type, Eukiefferiella claripennis-type B, Orthocladius (Orthocladius) dentifer-type, O. (Mesorthocladius) frigidus, Orthocladius (Euorthocladius) sp. and Tanytarsini indet. Most of these types have possibly broad distribution patterns in Europe. We believe that due to specific features of each region, this paper will serve as a helpful manual for limnologists and paleolimnologists working not only in the Tatra Mts. but also in the whole Carpathian region.

“…210 Pb could be determined via its daughter radioisotope (polonium) using alpha spectrometry. The deposition of 210 Pb into sediments can be used to measure sedimentation rates and sediment age ( 210 Pb method) (Sanchez-Cabeza and Ruiz-Fernandez 2012; Hamerlík et al 2016;Szarlowicz et al 2018). In addition, 210 Po, being an alpha emitter with high radioactivity, makes a major contribution to the natural radiation received by humans, because of its accumulation from food especially from fish or shellfish (Skwarzec 1988(Skwarzec , 1997Ugur et al 2002;Lazorenko et al 2002).…”

The radioactivity of alpha emitter radioisotope 210 Po can be used to determine the amount of 210 Pb radionuclide. This radioisotope is commonly used in the dating of marine as well as freshwater lake sediments. In this type of research, the collected samples are small, often 1.5-3 g (wet sediments), especially if we work with sediments taken from mountain lakes. This work presents the problems found with 210 Po determinations in a sample weighting 0.1 or 0.2 g. The analysis is based on the decomposition of samples, the concentration of the analyte, preparing source via spontaneous deposition on a silver discs, and alpha measurements of this source. The aim of this work was to optimize every stage of the procedure. The main assumption of the research was to minimize the weight of samples, the amounts of reagents taken for radiochemical determinations, and to eliminate hydrofluoric acid during the analytical process. The study focused on the optimization of the decomposition of sediments (microwave digestion with concentrated HCl and HNO 3 acids), the adsorption of polonium on the container wall in time, and the deposition conditions. The results show that there is a possibility to determine 210 Po in small amounts (0.1-0.2 g) of sediments without using hydrofluoric acid with the yield of radiochemical procedure above 90%. The procedure was checked by reference material, and good accuracy and precision were achieved.
