Abstract
In the present work, we attempt to test the applicability of common trophic state indices such as Carlson’s index (1977), probability distribution diagrams of Vollenweider (1982), and fixed boundary systems of the OECD (1982) and of Nurnberg (1996) for evaluating the risk of [...] Read more.
In the present work, we attempt to test the applicability of common trophic state indices such as Carlson’s index (1977), probability distribution diagrams of Vollenweider (1982), and fixed boundary systems of the OECD (1982) and of Nurnberg (1996) for evaluating the risk of eutrophication in the Sejnane reservoir in North Tunisia. The environmental parameters considered include monthly values of nutrients, chlorophyll a, Secchi transparency, turbidity and dissolved oxygen over a decade of monitoring from November 2001 through October 2011. To compile data and to identify key aspects of water quality, a multivariate technique as Principal Component Analysis was performed. Results show that productivity is limited by sedimentary turbidity, which contributes to decreasing water clarity and promotes the adsorption of phosphorus to suspended matter that decreases, indirectly, the bioavailability of nutrients. The Nurnberg model provides an accurate assessment of eutrophication with a clear internal coherence between self-indicators, and appears to be the most suitable way to evaluate eutrophication risk in the reservoir.

The optimal number of hydrological monitoring stations for the annual values, the maximum spring, the minimum summer-autumn and the minimum winter river runoff in Belarus is determined. The research on optimization of the hydrological network of Belarus led to a conclusion about the optimum number of hydrological stations in the country, but in the case of observing the values of the annual runoff, the number of the existing plants is the minimum necessary, and reducing their number is inadmissible. On the basis of trends in air temperature changes, precipitation and humidity deficits from 1985 to 2009, the forecasts of these parameters are prepared until 2020. Taking into account the models of climatic parameter change, a possible change in the water regime of the rivers in the future is investigated. Full article

The non-selective, post-emergence herbicides based on glyphosate [N-(phosphonomethyl) glycine] are one of the most widely used pesticides in agriculture, urban areas and forestry. Although there has been documentation on the physical, chemical and toxicological properties of glyphosate, the aquatic toxicity of such formulations still requires assessment and evaluation. In the present study, we describe deliberate use of glyphosate-based herbicide in a bathing area of Lake Lednica (Wielkopolska, Poland) by unknown perpetrators in April, 2011. Glyphosate was detected using gas chromatography mass spectrometry (GC-MS) in the water samples collected from the bathing area at a mean concentration of 0.09 mg dm−3. Aboveground parts of emerged macrophytes (Phragmites australis and Typha latifolia) covering the investigated area were completely withered. Studies of benthic macroinvertebrates revealed no significant differences in taxa number between event (13 taxa) and control (14 taxa) sites although differences in abundance of particular taxa were observed. Significantly lower numbers of Chironomidae (by 41%), Oligochaeta (by 43%), Vivipariae (by 75%), Hirudinae (by 75%), Asellus aquaticus (by 77%), Gammarus pulex (by 38%) and Dreissena polymorpha (by 42%) were found at the glyphosate-treated site. Furthermore, compared to the control, chironomids (Chironomidae) exposed to glyphosate were represented by specimens smaller in length while A. aquaticus only showed large adults. The ranges of glyphosate concentration in the tissues of sampled macroinvertebrates and Phragmites australis organs were 7.3–10.2 μg kg−1 and 16.2–24.7 μg kg−1, respectively. Our study indicates that glyphosate-based herbicides may have adverse effects on aquatic organisms including macroinvertebrates, thus their use in (or nearby) surface waters should be subject to strict limitation.

A Testimony of Detachment of an Inland Lake from Marine Influence during the Mid-Holocene in the Vestfold Hills Region, East Antarctica

A 47 cm long sediment core collected from an inland lake of the Vestfold Hills, East Antarctica has been examined to reconstruct the palaeolacustrine environmental changes. The core shows dates at two core intervals of 18–19 cm and 28–29 cm as 5050 ± 98 yrs BP and 5560 ± 96 yrs BP, respectively. The core exhibits a good amount of diatom population throughout the length. Prior to 5560 ± 96 yrs BP, the core shows high abundance of diatom population (>10 × 107 g−1) along with sufficient salt crystal, which indicates the connection of this lake with the marine environment. From 5560 ± 96 yrs BP to 5050 ± 98 yrs BP the total number diatoms decreased substantially along with the decrease in salt crystal, which indicates the withdrawal of the marine influence from the lake during that period. From 5050 ± 98 yrs BP to Recent, the low number of diatoms and the rare occurrence of salt crystal suggest that the lake remained mostly detached from the sea during the last 5000 yrs. Full article

Based on archival cartographic sources, teledetection materials, and research results in the scope of history and environmental sciences, changes occurring in the catchment of Lake Rotcze and its close vicinity over the last two hundred years were analysed. The area of the catchment is dominated by moderately fertile minerogenic soils on which forest assemblages developed (poor hornbeamoak forest Tilio-Carpinetum and thermophilous oak forest Potentillo albae-Quercetum). The first trace of anthropopressure was a clearing at the southern shore of the lake, for agricultural use, established not later than at the turn of the 17th and 18th century. The forests were almost completely cleared in the first quarter of the 20th century, and transformed into cultivated land of the village of Grabniak. A large fragment of the catchment is occupied by peatlands, constituting the final stage of lake-peatland succession developed in the former bay of fossil Lake Uściwierskie of which Lake Rotcze constitutes the remains. During the 20th century, the peatlands were intensively drained. This resulted in their overdrying, and growing over with bushes and marshy forests. In the 20th century, Grabniak was an agricultural village. Over the last 25 years, it has turned into a recreation resort. The relatively short agricultural and settlement activity in the lake catchment, in comparison with other parts of Poland, makes the lake appropriate for palaeolimnological reconstruction in terms of looking for reference conditions (sensu WFD).

The aim of the study was the long-term observation of changes in the trophic status of the Great Masurian Lakes versus changes in the management of lakes’ watershed. The Great Masurian Lakes (GML), a system of interconnected glacial lakes, were, until the 80s, receivers of untreated and partially treated sewage from cities and diffuse sources, particularly in the tourist season. In the 90s, state farm areas turned into fallow land, which reduced the input of nutrients from diffuse sources. In the late 90s municipal sewage plants began to be systematically built in cities and the larger villages of the region. An analysis of changes in the trophic status of the GML hydro-system during the period of 35 years was based on rotifer indices of lake trophy. Results of the analysis show that in 1976 lakes in the northern and southern part of the GML system were mesotrophic or meso-eutrophic, while in the central part, in the triangle formed by three cities, the beginning of eutrophication was observed. After several years of increased inflow of nutrients due to the impact of tourism, a marked increase in the trophy of lakes was noticed in the central part of the system. In the 90s, after the collapse of large-scale agriculture and the installation of modern sewage treatment plants, the trophic status of nearly all lakes in the central and southern parts of the system ranged between meso-eutrophy and low eutrophy. The exceptions were Lake Nidzkie, whose trophy increased and Lake Niegocin, which became mesotrophic. Changes in the trophic status of the studied lakes indicate high sensitivity of the GML system to anthropogenic changes in their watershed. Full article
