Mining activity generates a large quantity of mine waste. The potential hazard of mine waste depends on the host mineral. The tendency of mine waste to produce acid mine drainage (AMD) containing potentially toxic metals depends on the amounts of sulfide, carbonate minerals, and trace-element concentrations found in ore deposits. The acid mine process is one of the most significant environmental challenges and a major source of water pollution worldwide. AMD and its effects were studied in northwest Turkey where there are several sedimentary and hydrothermal mineral deposits that have been economically extracted. The study area is located in Can county of Canakkale province. Canakkale contains marine, lagoon, and lake sediments precipitated with volcanoclastics that occurred as a result of volcanism, which was active during various periods from the Upper Eocene to Plio-Quaternary. Can county is rich in coal with a total lignite reserve [100 million tons and contains numerous mines that were operated by private companies and later abandoned without any remediation. As a result, human intervention in the natural structure and topography has resulted in large open pits and deterioration in these areas. Abandoned open pit mines typically fill with water from runoff and groundwater discharge, producing artificial lakes. Acid drainage waters from these mines have resulted in the degradation of surface-water quality around Can County. The average pH and electrical conductivity of acid mine lakes (AMLs) in this study were found to be 3.03 and 3831.33 lS cm -1 , respectively. Total iron (Fe) and aluminum (Al) levels were also found to be high (329.77 and 360.67 mg L -1 , respectively). The results show that the concentration of most elements, such as Fe and Al in particular, exceed national and international water-quality standards.

“…lanceolata HusTedT was also discovered in Indonesia (Lake Toba, Sumatra), as a fossil freshwater diatom (HusTedT 1935). LessmaNN et al (1999) recorded P. acoricola in an extreme acidic lake with high concentrations of calcium, iron, aluminium, manganese and sulphate. This taxon has a variable morphology resembling P. obscura KrassKe (carTer 1972).…”

A new benthic freshwater diatom species belonging to the genus Pinnularia eHreNb. has been recorded in the Água Forte stream surrounding the Aljustrel mining area in southern Portugal. Pinnularia aljustrelica Luís, aLmeida et ecTor sp. nov. is described as a new species based on light and scanning electron microscopy observations and on its particular habitat in an acidic environment due to acid mine drainage, high metal concentrations (As, Cd, Cu, Fe, Mn, Pb and Zn) and high sulphate and conductivity. The taxa most similar to P. aljustrelica are P. acidophila HoFmaNN et Krammer, P. acoricola HusTedT and P. acoricola var. lanceolata HusTedT, so type materials of these taxa were studied for comparative purposes. Although, the ecology of the three similar taxa is also quite similar, the new species has a combination of particular morphological characteristics studied under LM and SEM that separates it from the rest. Pinnularia aljustrelica has a general shape relatively similar to P. acidophila and P. acoricola, but the valve outline is not as linear as in P. acidophila and not as oval as in P. acoricola.

“…Most of them are aquatic insects, predominantly chironomid larvae, which can reach relative high densities in some lakes. These organisms appear therefore to be important as primary consumers and/or top-predators (Lessmann et al, 1999;Wollmann et al, 2000;Rodriguez, 2001). Although some studies have dealt with their distribution patterns or their ecology in acidic mining environments (e.g.…”

Influence of bioturbation on the biogeochemistry of littoral sediments of an acidic post-mining pit lake

Abstract. In the last decades, the mining exploitation of large areas in Lusatia (Eastern Germany) but also in other mining areas worldwide has led to the formation of hundreds of pit lakes. Pyrite oxidation in the surrounding dumps makes many such lakes extremely acidic (pH < 3). The biogeochemical functioning of these lakes is mainly governed by cycling of iron. This represents a relevant ecological problem and intensive research has been conducted to understand the involved biogeochemical processes and develop bioremediation strategies. Despite some studies reporting the presence of living organisms (mostly bacteria, algae, and macroinvertebrates) under such acidic conditions, and their trophic interactions, their potential impact on the ecosystem functioning was poorly investigated. The present study aimed to assess the influence of chironomid larvae on oxygen dynamics and iron cycle in the sediment of acidic pit lakes. In the Mining Lake 111, used as a study case since 1996, Chironomus crassimanus (Insecta, Diptera) is the dominant benthic macro-invertebrate species and occurs at relatively high abundances in shallow water. A 16-day laboratory experiment using microcosms combined with high resolution measurements (DET gel probes and O 2 microsensors) was carried out. The burrowing activity of C. crassimanus larvae induced a 3-fold increase of the diffusive oxygen uptake by sediment, indicating a stimulation of the mineralization of organic matter in the upper layers of the sediment. The iron cycle was also impacted (e.g. lower rates of reduction and oxidation, increase of iron-oxidizing bacteria abundance, stimulation of mineral formation) but with no significant effect on the iron flux at the sediment-water interface, and thus Correspondence to: S. Lagauzère (lagauzere@gmail.com) on the water acidity budget. This work provides the first assessment of bioturbation in an acidic mining lake and shows that its influence on biogeochemistry cannot be neglected.
