Bottom sediments accumulate rapidly in urban reservoirs and should be periodically removed. Their high organic matter content makes them valuable fertilizers, but they often contain toxic substances. The present study compares the responses of the dicotyledonous Tagetes patula and monocotyledon Festuca arundinacea to the presence of such sediments in soil and to soil inoculation with two rhizobacterial strains (Massilia niastensis p87 and Streptomyces costaricanus RP92) isolated from contaminated soil. Total soluble protein, total chlorophyll content, as well as chlorophyll a/b ratio, degree of lipid peroxidation (TBARS), α-tocopherol content, total phenolic compounds (TPC) content and anthocyanins content were examined in the leaves of investigated plants. T. patula was more sensitive to the toxic substances in the sediments than F. arundinacea. Rhizobacterial inoculation reduced the toxic effect of the sediment. RP92 has a more favorable effect on the condition of T. patula than p87. F. arundinacea was not adversely affected by the addition of sediments or inoculation with the p87 or RP92 strains. Both tested plant species are suitable for planting on soils enriched with urban sediments, and the addition of bacterial inoculums promote plant growth and reduce the damage caused by the xenobiotics contained in the sediments.

The study of heavy metal speciation in bottom sediments of the Vyshnevolotsky water reservoir is presented in this paper. Sequential selective procedure was used to determine the heavy metal speciation in bottom sediments and thermodynamic calculation — to determine ones in interstitial water. It has been shown that Mn are mainly presented in exchangeable and carbonate forms; for Fe, Zn, Pb и Co the forms are related to iron and manganese hydroxides is played an important role; and Cu and Ni are mainly associated with organic matter. In interstitial waters the main forms of heavy metal speciation are free ions for Zn, Ni, Co and Cd, carbonate complexes for Pb, fulvate complexes for Cu. Effects of particle size and organic matter content in sediments on distribution of mobile and potentially mobile forms of toxic elements have been revealed.

Total phosphorus and organic matter content in bottom sediments of lake under restoration measures with iron treatmentRusałka Lake is a shallow, man-made, strongly eutrophicated reservoir, being a place of recreational activities for Poznan citizens. Restoration measures with the use of iron sulphate were conducted in years 2006-2007. Phosphorus and organic matter concentrations in lake sediments were analyzed in years 2005-2007 at two research stations (profundal and littoral) to determine its changes under the influence of restoration. Greater phosphorus concentrations were noted in profundal (max 1.55 mg P g-1dry weight (DW)) than in littoral (max 0.98 mg P g-1DW). An increase of P amount in sediment was observed after iron treatment. Among phosphorus fractions Res-P dominated, i.e. phosphorus biologically unavailable for organisms. Organic matter content reached 23.1% in profundal, while 14.8% in littoral. Its amount decreased in following years.

Water Catchment

Water bodies of river-lake systems can act as barriers in the movement of nutrients and toxic heavy metals outside their water catchment area. These components can be suspended in the water column, deposited in bottom sediments or bioaccumulated by the vegetation in the water body. A constant exchange of substances takes place between bottom sediments and macrophytes. The composition of bottom sediments and their distribution affects the intensity of nutrients and metals assimilation by macrophytes in the river-lake systems. The aim of research was to analyse the effect of bottom sediments on the nutrients and metal content in macrophytes. It was demonstrated that tissues of plants anchored in sediments that were more abundant in nutrients had higher contents of biogenic components and heavy metals. The properties of bottom sediments, mainly their granulometric composition, but also organic matter content and pH, determine the content of biogenes and heavy metals in macrophytes to a significant extent. On the other hand, it was demonstrated that aquatic plants could affect the grain size in the sediments. Macrophytes and sediments of river-lake systems play a very important role in reducing the transport of nutrients outside the area of the system, through capturing and incorporating them into the tissues of aquatic plants.

AbstractSpyra A. Woodland ponds as an important habitat of Hippeutis complanatus (Linnaeus 1758) occurrence - effect of environmental factors and habitat preferences. Ekológia (Bratislava), Vol. 33, No. 2, p. 101-115, 2014.In industrial areas, woodland ponds are refuges of biological diversity. The impact of environmental factors such as the physico-chemical properties of water, organic matter content in bottom sediments and various types of substratum on the occurrence of Hippeutis complanatus were assessed. In Poland, it is considered to be a species with an established but unspecified risk, deserving the status of endangered species due to the decline of wetland environments. A Canonical Correspondence Analysis (CCA) revealed associations between the distribution patterns of freshwater snails species and the concentration of nitrates (NO3) and calcium (Ca) as well as pH and the organic matter content in the bottom sediments. Based on statistical relationships, results of study suggest that the kind of substratum (Typha latifolia remains, Phragmites australis remains, fallen leaves of waterside trees) has an impact on the occurrence of freshwater snails including Hippeutis complanatus for which the preferred substratum is the fallen leaves of waterside trees and sites with a high content of organic matter in bottom sediments. The study has shown that isolated water bodies located in forest complexes can be refuges for species that occur in small numbers in other types of aquatic environments.

In 12 astatic pools, each of which was characterised by the dominance of phytocenoses of one of three plant associations, investigations were performed on the physico-chemical properties of the water and bottom sediments, in order to establish the relations between the habitat conditions and vegetation. The criterion of the degree of saltiness of the bottom sediments and the specific conductivity of water in these water bodies allows to order them according to their decreasing fertility as follows: 1) water bodies with dominant phytocenoses of the association <em>Equisetetum limosi</em>, 2) with <em>Caricetum elatae</em>, 3) with <em>Typhetum latifoliae</em>. The type of vegetation indicates also connections with other properties of the water (hardness, oxidability, pH, chloride content) and of the bottom sediment (organic matter content, chlorides, magnesium and various forms of nitrogen). Correlation between the chemical composition of the water and depostis has only been demonstrated in the case of chlorides.

Abstract Oil leakage from gas stations in Taiwan is commonly caused by the corrosion of oil tanks or loose pipeline joints, contaminating the soil and groundwater near the gas station. Wine-processing waste sludge (WPWS) does not contain toxic substances and has a high organic matter content. Thus, it has high affinity for methyl tert-butyl ether (MTBE) and benzene, toluene, ethylbenzene, and xylenes (BTEX), being suitable for application in preventing and controlling groundwater pollution. In this study, a permeable reaction barrier (PRB) constructed utilizing WPWS in a large water tank was designed to simulate the diffusion and blockage of gasoline plumes in an aquifer. The constructed WPWS PRB had a rectangular shape with a thickness and height of 9 and 60 cm, respectively. The depth in the aquifer was adjusted to 50 cm. MTBE was detected in the aquifer downstream of the WPWS PRB every day during the experiment; however, the maximum concentration detected was only 5.33 ppb. BTEX were only detected on 3 days during the experiment and had maximum concentrations of 1.76, 2.28, 0.34, and 0.60 ppb, which are below the water quality control standards.

A preliminary study of the gamma radiation effects on the antioxidant compounds present in cork cooking water was carried out. Radiation studies were performed using radiation between 20 and 50 kGy at 0.4 and 2.4 kGy h−1. The radiation effects on organic matter content were evaluated by chemical oxygen demand. The antioxidant activity was measured by ferric reducing power assay. The total phenolic content was studied using the Folin-Ciocalteau method. Results show that gamma radiation increases both the amount of phenolic compounds and antioxidant capacity of cork cooking water. These results highlight the potential of this technology for increasing the added value of cork waters.

Analysis of cultivable aerobic bacteria isolated from bottom sediments in the Wijdefjorden region, SpitsbergenThe paper presents the first physicochemical and microbiological studies conducted in the northern area of Svalbard (Spitsbergen). Ten sediment samples were collected from the bottom of the longest fjord in the region, Wijdefjorden. Bottom sediments from ten lakes lo- cated along the shores of Wijdefjorden and Woodfjorden were also sampled. Organic matter content (LOI), water content, temperature, pH, and salinity of the sediments were determined. The quantity of aerobic bacteria cultured on various growth media at 4°C, 14°C, and 37°C ranged from 102to 106cfu/g of wet sediment mass, depending on the type of sampling station (fjord or lake). The number of bacteria did not correlate with organic matter content. Out of the 37 bacterial strains isolated from Wijdefjorden, 48% and 70% revealed ureolytic and proteolytic activity, respectively. The proportion of freshwater strains with ureolytic and proteolytic activitywas 32% and 55%, respectively. Antibiotic resistance testing indicated that bacterial strains from the bottom sediments of the lakes were resistant to 8 antibiotics (out of the 18 investigated). Possible sources of this resistance are discussed. Using 16S DNA analysis, bacterial isolates from the lakes were identified asPseudomonassp., whereas frequently occurring strains in bottom sediment of the fjord werePseudoalteromonassp.

Twenty grass populations were evaluated for dry matter yield, N content, P content, organic matter content, organic matter digestibility and winterhardiness. Of these populations, Agropyron intermedium was most suitable for a hay crop on a well-drained irrigated soil. Agropyron trichophorum, Bromus inermis, and Phalaris arundinacea were lower-yielding alternatives that had a satisfactory N content and good digestibility. Elymus angustus shows promise as an irrigated hay crop and should be evaluated further. The usefulness of the following populations was limited by one or more of these factors: low yield (Y), low N content (N), low digestibility (D) and lack of winterhardiness (W): Dactylis glomerata ’Kay’ (Y,N,D), Dactylis glomerata ’Chinook’ (Y,N,W), Elymus sibiricus (Y), Festuca arundinacea ’Kenmont’ (Y,N,W), Festuca elatior ’Trader’ (Y,N), Phleum pratense (Y,N,D), Poa ampla ’Sherman’ (N,D), Poa bulbosa cv. P4874 (Y,N,D), and Poa pratensis (Y,N,D).
