“…The Pb trend observed in the present study is in line with those reported in the literature for other catchments throughout Europe, especially the peak observed for the 2-4 core sections (Bra ¨nnvall et al, 2001;Renberg et al, 2001;Arnaud et al, 2003Arnaud et al, , 2004Spadini et al, 2003;Camarero et al, 2009b;Nedjai et al, 2011). This peak could be likely associated to the 1970s, when Pb deposition rate reached the highest level due to the increase in fossil fuel combustion and leaded gasoline use (Nizich et al, 2000;Renberg et al, 2000;Bra ¨nnvall et al, 2001;Siver & Wonziak, 2001).…”

“…In this context, indirect dating of the top core sections could be hypothesized through comparisons with other studies in European lakes. As the highest peak in total Pb concentrations within core sediments is reported during the 1970s (Bra ¨nnvall et al, 2001;Renberg et al, 2001;Arnaud et al, 2003Arnaud et al, , 2004Spadini et al, 2003;Camarero et al, 2009b;Nedjai et al, 2011), the detection of this peak in the top sections of the Balma Lake core could allow the identification of the core section corresponding to the 1970s period, when fish was introduced in the Piedmont area alpine lakes.…”

“…No evidence of sediment movement after sedimentation emerged during the sample analysis. The measured Pb data have been compared with others different Pb analyses recorded on cores collected in nearby lake basins (Arnaud et al, 2003(Arnaud et al, , 2004Camarero et al, 2009b;Nedjai et al, 2011) and other European lakes (Bra ¨nnvall et al, 2001;Renberg et al, 2001;Spadini et al, 2003). Also considering data published by ISPRA ( 2009), which showed a decrease in Pb emissions in Italy after 1990, it was possible to estimate that the observed peak could be likely related to the 1970s.…”

Changes in midge assemblages (Diptera Chironomidae) in an alpine lake from the Italian Western Alps: the role and importance of fish introduction

Introduction of exotic species is one of the major human impacts for decline in autochthonous biodiversity. In freshwater lentic environments, alien fish introduction heavily shapes macrobenthic invertebrate structure, with special regard for Chironomidae (Diptera) community. These effects could be more evident in alpine lakes whose environments are considered as remote and undisturbed, but extremely susceptible and vulnerable to both natural and anthropogenic impacts. In this context, modern and subfossil chironomid assemblages were studied in a highaltitude lake (Balma Lake, Piedmont, Italy) which was not previously investigated and subject to brook trout introduction for recreational fishing at the end of the twentieth century (after 1970). Seasonal samplings (summer, autumn) were performed in five littoral and three deep sites, while a core sample was extracted from the deepest point of the lake. The analysis highlighted significant differences in subfossil chironomid communities before and after fish introduction and between subfossil and modern communities, with notable decrease in recent diversities. Dissimilarities were mainly related to Corynocera oliveri, Zavrelimyia, Micropsectra, Metriocnemus, and Heterotrissocladius marcidus type. Therefore, this study highlights the importance and effects of anthropic environmental events, such as fish introduction, in climate reconstructions and their interpretation, especially regarding the last 100/200-year period, when human environmental issues have become more significant.

Abstract:Various elements are accumulated in bottom deposits in concentrations that significantly exceed the levels observed in lake water. Under certain conditions, this can lead to secondary contamination of water, posing a threat to aquatic organisms. The aim of this study was to evaluate the spatial distribution of Pb, Zn and Cr pollutants in the bottom deposits of Lake Sunia. The investigated water body is situated in the Olsztyn Lakeland (western part of the Masurian Lakeland), approximately 30 km north of the city of Olsztyn, in the municipality of Swiatki. The lake has a total area of 111.6 ha and a maximum depth of 8.8 m. The inflow to and the outflow from lake are situated in its south-western and north-western part, respectively. The lake features a bay which is separated from the main water body by a shallow zone. Its catchment area comprises mainly agricultural land. The total area of supply of lake is 450 ha of which inflow catchment area is 70 ha. Most of the catchment area is agricultural land (91%), and in particular arable land, the rest of the area (5%) are the barren, and trees (4%). In the area of the lake is dominated by power-sandy loam soil in the passing sands and clay loam strong little sandy. In terms of particle size are a summary of the soil that is difficult permeable to water and nutrients. Taking into account the valuation of soil classification in the vast quantities of soil are included in the class IVa, IIIa and IIIb. The average content of organic matter in the lake was determined at 24%. Significant accumulation of organic matter results from intense inflow of biogenic substances from farmed areas in the catchment. The average concentrations of trace elements in the analyzed water body were arranged in the following series: Cr < Pb < Zn, and their ratios were determined at 8.1 < 22.9 < 45.2. Higher levels of heavy metals were observed in the profundal zone, whereas lower concentrations of the analyzed elements were noted in littoral zone sediments.Keywords: anthropogenic pressure, bottom deposits, heavy metals All water reservoirs have their bottom, which settle on the organic and inorganic suspensions. They form a bottom deposits characteristic for catchment and morphological feature [1]. The settlement of allochthonous material formed outside the sedimentation zone and autochthonous material created at the place of sedimentation leads to the formation of bottom sediments in water bodies [2]. The content of chemical compounds in sediments is determined by the type of bed rock forming lake catchments as well as land use patterns in the catchment area. Rock strata constitute a point of reference (geochemical background)
