“…Eunotia spp. are diatoms that tolerate low pH water and often occur in acidic and even extremely acidic water bodies (Koschorreck and Tittel 2002;Sienkiewicz and Gąsiorowski 2017). The first period of the lake's development, during which Eunotia dominated, lasted for 77 years (i.e., two times longer than the first phase in TR-31 ( Fig.…”

“…4). The reconstructions of DI-pH for both lakes were performed using the Mining pH training set created for pit lakes (Sienkiewicz and Gąsiorowski 2017). The values of the reconstructions were determined using the weighted averaging (WA) method with classical and inverse deshrinking.…”

“…Another important feature influencing the water chemistry in pit lakes is the length of time since the end of mining. As a rule, in the case of natural neutralization, younger lakes that form after the end of ore exploitation are more acidic and have higher concentrations of trace metals than older lakes (Sienkiewicz and Gąsiorowski 2017). However, the period of natural neutralization depends primarily on the factors above-mentioned.…”

TR-31 and TR-33 are post-mining lakes located within the Łuk Mu_ zakowa Geopark (western Poland). They were created after the end of lignite exploitation in the second half of the nineteenth century. Although they are located in neighbouring excavations and currently have neutral pH levels, they developed differently. Based on the diatom communities, elemental analyses and isotopic data, TR-33 experienced a natural neutralization process from an acidic state to nearly neutral due to the presence of lignite residuum at the bottom of the excavation. Pyrite is common in lignite deposits and gangue, and its oxidation causes acidity in aquatic ecosystems. The primordial state of the acidic water in TR-33 was confirmed by the development of diatoms belonging to the Eunotia genus, which can tolerate acidic environments. The excavation in TR-31 was filled by rain and groundwater, and the pH of the water was neutral or nearly neutral from the beginning of lake's existence. This is indicated by the diatom assemblages during the initial phase of lake formation and the reconstruction of the water pH. The relatively low values of the C/N ratio in the deep layers of the core indicate the lack of lignite deposits at the bottom of TR-31.

“…2). None of these values exceeds the range of limit values specified by the Food and Agriculture Organizations of the United Nations (FAO) [12] (2 g•dm -3 ); in addition, it was observed, only for tributary II, that the standards specified by the World Health Organization (WHO) [13] (0.5 g•dm -3 ) were slightly exceeded. This is a watercourse with a rocky bed and an intense water flow; for this reason, the chemical pollutants contained in the water do not accumulate in sediments but are transported to the lake.…”

This study assessed the water quality in Lake Wydmińskie (Warmińsko-Mazurskie Voivodeship) based on the content of both organic and inorganic pollutants flowing into the lake with water from drainage systems. The study demonstrated that the water flowing into the lake through drainage ditches that drain the improved part of the catchment area of the lake, was a potential source of diffuse pollutants and excess chemical components were deposited in the lake which could lead to its degradation. The most polluted water was found in the main tributary and the lake bay fed by its water. For this reason, it was concluded that the greatest problem was the area-wide sources of pollutants outgoing from agricultural areas. It was also found that water flowing out of the lake was of a considerably better quality than water flowing into the lake through the ditches. This clearly indicates the accumulative role of the lake on the route of pollutant migration from agricultural sources.

“…Recently, Luís et al (2019) detected a significantly low diatom diversity and the presence of specific bioindicators of acid-and metal-contaminated waters, such as P. aljustrelica, in sites affected by AMD (Alentejo Province, south of Portugal). Again, diatom species richness and diversity was very low in the acidic lakes located in the Łuk Mu_ zakowa along the Polish-German border (Sienkiewicz & Gąsiorowski, 2017). In these communities, many teratological valves of Eunotia spp.…”

Over the last years, issues concerning diatom teratological forms and environmental stress have received growing interest within the scientific community. Publications on this topic dated back to 1890 and were summarized in a review published in 2009 by the journal Hydrobiologia, accounting for high citation rates (i.e. 117 citations Scopus and 232 citations Google Scholar, October 2020). This wide interest stimulates the authors to further unravel teratological forms significance in the light of the most recent publications (2010–2020). Diatom teratological forms are one of the best individual-level biomarkers since they provide a rapid response to several environmental stressors, including new emerging pollutants. The mechanisms involved in teratological valve likely involve both cytoskeleton and silicon metabolic pathway impairments. However, teratologies do not seem to weaken the reproduction capacity and viability of the affected individuals. We recognized eight types of teratologies as involving different parts of the valve, depending on genus. In order to summarize the information obtained by several years of research, we suggest a four-step procedure aimed at providing a theoretical pathway that researchers should follow to better explain results obtained in next-future studies and representing a starting point for the development of an environmental index based on teratological forms.
