“…Macrophytes are aquatic plants that grow in/or near water and can be classified as emergent, submerged or floating plants. Some studies have investigated the capabilities of macrophytes to remove heavy metals from the environment (30,31,45), their role as biomonitors of environmental metal levels (36,40,41) and their capacity as biological filters of the aquatic environment (48).…”

“…This is a result of difference in the characteristics of stress: 1) quarrying produces extremely long term disturbance and 2) the sediments produced in quarries alter the chemistry of water (e.g., change of pH), which does not occur in experiments where natural stream sediments were used (Kim et al 2007;Mishra et al 2008).…”

“…Papers related to the biological assessment of the effects of quarrying on aquatic systems are sparse (Nuttall 1972;Nuttall & Bielby 1973). This is surprising, given both the imaginable and the proven effects of various mining effluents (Quinn et al 1992;Kim et al 2007;Mishra et al 2008). Most quarries produce extreme amounts of fine particles (Felekoglu 2007) which might be transported by wind across great distances and affect all types of habitats.…”

Destructive effect of quarry effluent on life in a mountain stream

Quarrying is a widespread method for acquiring construction material. The studies of quarrying effects to date have been conducted mostly in the fields of geology, (hydro)geochemistry and landscape management while ecological studies on effects of quarrying are surprisingly few. The goal of this study was to assess some ecological effects of quarry mining on mountain stream habitats. The study was performed at Bistra Stream on Medvednica Mountain in NW Croatia. The quarry is located 3 km downstream from the spring. Samples were taken at four sites on four dates during the spring of 2006. Standard physico chemical parameters were measured and triplicate benthos samples were taken using a 30 × 30 cm Surber sampler. Turbidity, pH and temperature increased significantly downstream of the quarry. All biocenotic descriptors decreased significantly downstream of the quarry including total taxa (by 60%), total number of individuals (by 85%), diversity index (by 56%). The most important cause of such changes in the macroinvertebrate assemblage structure was the change in pH and turbidity. The magnitude of changes in the macroinvertebrate assemblage structure was due to the extremely long duration of disturbance. However, we believe that the recovery of aquatic assemblages, upon closure of the quarry, would be fast and successful because of nearby streams that may serve as a recolonizing source.

“…Calcium bound P is insensitive to redox potential and once deposited in bottom sediments, it may get long-term retention (Kufel et al 2013). Sediment is an important storage sink for metals (Mishra et al 2008;Nemati et al 2011). The mobility and bioavailability of metals strongly depend on their specific chemical forms and ways of binds to each of the different phase (Karadas and Kara 2012).…”

The role of calcium (Ca) in the cycle of phosphorus in water environment depends on the speciation of Ca in sediments, and reliable Ca sequential extraction method is useful for obtaining information about Ca transport processes from sediment to water. Experiments have been carried out to develop a simple but robust Ca sequential extraction method for identification of Ca portioning in sediments. The sequential extraction protocol was modified for extractants, extracting time, concentration and pH of the reagents in the first three steps of Tessier sequential procedure. With optimum conditions, there were 1:25 sediment to solution ratio and 3 h of extracting time shaken with NH 4 AC (1 mol L -1 , pH 7.0) (exchangeable Ca fraction); 1:25 sediment to solution ratio and extracted with NH 4 AC (1 mol L -1 , pH 5.0) for 5 h (carbonatebound Ca fraction); and 1:30 sediment to solution ratio and extracted with NH 2 OHÁHCl (0.5 mol L -1 , pH 1.5) for 6 h (Fe and Mn oxides bound Ca fraction). The recovery for Tessier procedure ranged form 35.6 to 71.1 %, while the recovery for the modified Tessier procedure ranged form 46.1 to 86.9 %. These results revealed that Tessier procedure underestimated the proportion of Ca in exchangeable fraction. In sediments, Ca was mainly exchangeable and carbonate bound, which was considered as the most liable fractions.
