Opis:: The present study was performed for the period of one year from June 2012 to May 2013 in order to understand the physico-chemical properties of sediments samples collected along the Mahim Creek of Mumbai. The annual average pH value of the creek sediments was recorded as 9.22. It is feared that such conditions may increase the alkalinity of Creek water which according to USEPA will increase the physiological stress of many aquatic species resulting in decreased reproduction, decreased growth, disease, or death thereby reducing the biological diversity of the Creek. The total organic matter in the creek sediments was found to be maximum of 10.30 % with an annual average concentration of 6.29 %. Although organic matter is a primary source of food for benthic organisms and is important in maintaining a viable ecosystem, too much of organic matter deposited in the sediments will be responsible for depletion in dissolved oxygen content of the creek water causing unpleasant odours and may also increase the rate of eutrophication. From the results it appears that as India moves towards stricter regulation of industrial effluents to control water pollution, greater efforts are required to control the discharge of pollutants into the ecosystems.

Opis:: Zinc present in water penetrates into the organism of a fish either directly, through the skin and gills, or indirectly, with food taken into the alimentary canal. The toxocity of this metal is associated with the transporting function of blood, which distributes it over the whole organism. The aim of this paper was to assess the zinc content in water and bottom sediments collected from the Dunajec River, and also in selected organs of bleak (Alburnus alburnus L.). The bioaccumulation factors for this element in the muscles, liver, skin and bones of the fish were calculated from the results of the research, which was carried out in 2011. Samples of water and bottom sediments were collected twice, in July and October, at 5 research points located in Szczepanowice, Janowice, Wróblowice, Lusławice, and Zakliczyn. Twenty-nine specimens of bleak were provided by members of the Polish Angling Association (PZW — Polski Związek Wędkarski), from catches performed in the second half of July. The zinc concentration in the samples was determined by inductively coupled plasma atomic emission spectrometry at a wavelength of 206.200 nm, conducted on an Optima 7600 DV spectrometer made by Perkin Elmer. The limit of detection for zinc was 5.9 μg · dm-3. High concentrations of zinc in the water were found, indicative of anthropogenic enrichment of the river with this element. The zinc content in the analysed sediments was below the geochemical background value for bottom sediments in Poland. Zinc concentrations in the fish varied within a range from 152.6 to 352 mg ∙ kg-1 in the skin, from 158.8 to 271.3 mg ∙ kg-1 in the bones, from 27.32 to 97.35 mg ∙ kg-1 in the muscles, and from 82.39 to 230.7 mg ∙ kg-1 in the liver. The mean content of zinc in individual organs decreased in the following order: skin > skeleton > liver > muscles. Zinc concentrations in individual organs of the fish were comparable with the ones determined eslewhere in environments polluted with this element.

Opis:: Sediments and organisms were sampled to determine organotin contents – butyltins (BTs) and phenyltins (PhTs) – at 12 locations in an estuarine ecosystem, the Lagoon of Venice, characterised by varying contamination impacts. The results showed that organotin contamination in sediments is at lower levels, ranging from 2.5±0.1 to 84±1 ng g−1 (d.w.) for ΣBTs and from 0.8±0.2 to 7±1 ng g−1 (d.w.), for ΣPHTs, than in organisms, where the highest concentrations were found in filter feeders like mussels – from 60±3 to 7632±148 ng g−1 (d.w.) for ΣBTs and from 0.80±0.01 to 4005±121 ng g−1 (d.w.) for ΣPHTs. The possible risk to human health was assessed on the basis of the consumption of edible species sampled in some areas of the lagoon.

Opis:: Anthropogenic alterations of the recent millennia of our era, in the loess areas of the Lublin Upland are clearly visible in the composition and character of the sediments that fill river valleys. This paper is an attempt to review this issue on the example of a small river valley that runs through the loess relief regions near Lublin. Samples were taken from deep drilling (up to 6 m) in the three cross-sections of the valley (Ożarów, Jastków, Snopków). A total of 172 samples taken from 5 drillings were investigated. The results obtained allow to conclude that delluvial processes dominated in the course of sediment formation that filled the Ciemięga river valley. Those delluvial processes started in the Neolyth by climatic changes and cutting down forests for the incoming agriculture - and have been intensified since the Middle Ages up till now. It is seen in a clear correlation between the growing part of ash components and mineral interbeddings in the peat deposits, as well as in the presence of cereal grains and weed pollen from cultivated fields in the investigated samples. In the chemical composition of the sediments, anthropogenic enrichment of K, P, Fe, Mn, Pb, Cr, Cu, Zn, and Co is observed.

Opis:: The aim of this study was to conduct the first comprehensive evaluation of carbon stock in the sediments of Avicennia marina (black mangrove) and Rhizophora mucronata (red mangrove) along the coastline of an arid region (Farasan Islands, Saudi Arabia). Such information is necessary for the development of any management plan for the mangrove ecosystems along the Saudi Red Sea islands and provide a rationale for the restoration of mangrove forests in Saudi Arabia. A. marina and R. mucronata locations showed significant (P < 0.001) differences in sediment bulk density (SBD) and sediment organic carbon (SOC) concentration with higher mean values for both in the sediments of A. marina. Considering the whole depth of sediment sampled (0–50 cm), the highest value of SOC stock (12.3 kg C m−2) was recorded at A. marina locations and the lowest (10.8 kg C m−2) at R. mucronata locations. Thus, the SOC stock of A. marina was greater than that of R. mucronata by 114.3%. Consequently, considering the rate of carbon sequestration and the area of mangrove forests (216.4 ha), the total carbon sequestration potential of mangroves in the Farasan Islands ranged between 10.3 Mg C yr−1 and 11.8 Mg C yr−1 for R. mucronata and A. marina locations, respectively. Thus, it is necessary to protect and restore these ecosystems for the sequestration of carbon and for their other valuable ecosystem services.

Opis:: This study evaluated the extent to which depth, sediment type, exposure to waves and coastal slope inclination modulate the relationships between regional nutrient loading, weather patterns and the species composition and dominance structure of macrobenthic invertebrate feeding groups in a brackish water ecosystem of the Baltic Sea. Irrespective of feeding function, the species composition and dominance structure of benthic invertebrate communities were determined by local abiotic variables such as exposure, depth and sediment type. Regional weather variables (average southerly winds, salinity, water temperature, ice conditions) either separately or interactively contributed to the variability of benthic invertebrates. Nutrient loading had significant effects on benthic invertebrates only in interactions with local abiotic or regional weather variables. Herbivores, deposit feeders and suspension feeders exhibited a stronger response to the studied environmental variables than carnivores. All this suggests that (1) the dynamic coastal habitats studied in this work are not very sensitive to shifts in nutrient loading and (2) local abiotic conditions and weather patterns largely define the observed biotic patterns. We believe that the benthic invertebrate time series will only be a better reflection of the nutrient loading signal if more years covering extreme events are included.

Opis:: Water bodies are the final sinks of all pollution with more than 90% of contaminants found in suspended particulates and bottom sediments. Only less than 10% is retained in the water column yet it attracts and receives great research attention. The pollution status and the potential ecological risk of three pools of water along a stream due to heavy metal enrichment from a nearby active gold mining tailings dam were assessed. The upstreamdownstream and sedimentological approaches to ecosystem health assessment were used. Potential uses of pool water were also evaluated based on measured water quality parameters. Heavy metals in water and sediment were determined using Flame Atomic Absorption Spectrometry. Results revealed that salinisation, acidification and heavy metals were exported from a mining tailings dam to the stream. The degree of contamination of pool water by heavy metals dictated water uses. Heavy metal concentrations imposed water use restrictions for aquatic life in a pool which directly received discharge from the mine tailings dam. The average heavy metal concentrations in sediments were lower than the standard shale values. Sediment quality guidelines and pollution indices showed that the stream was not polluted with heavy metals, thus posed no potential ecological risk. Continuous monitoring of tailings discharge and wash off is important to safeguard aquatic ecosystem and public health.

Opis:: Cd and Pb concentrations were measured in water, sediment and plant organs collected from selective sites located along the Bogdanka river (Poznań, Poland) in the 2012 growing season. The aim of the investigations was to monitor changes in heavy metal (HM) concentrations in different media over the periods, as well as to evaluate potential of two littoral plants, Phragmites australis and Typha angustifolia, for phytoremediation under natural conditions. Investigations revealed differences in HM concentrations in water and sediments. Higher values were observed in sediments than in water. The decrease in concentrations of both HMs in sediments was noted in two of the three selected water reservoirs during growing seasons, which suggests the possibility of their adsorption and accumulation by aquatic plants. Both investigated plant species accumulated ample amount of Cd and Pb in underground and aboveground plant tissues, however T. angustifolia revealed higher Cd translocation potential than P. australis. The latter revealed higher Pb accumulation in two lakes. Moreover, the translocation ratio was usually higher in spring, especially for Pb, in both plant species. Increasing level of pollution load index in sediment along the Bogdanka watercourse indicates accumulation of measured HMs.
Stężenie Cd i Pb mierzono w wodzie, osadach, jak również w organach roślin zebranych z wybranych stanowisk zlokalizowanych wzdłuż biegu rzeki Bogdanka (Poznań, Polska) w sezonie wegetacyjnym 2012 roku. Celem badań był monitoring zmian zawartości metali ciężkich w różnych mediach w określonym czasie, jak również ocena dwóch gatunków roślin szuwarowych, Phragmites australis i Typha angustifolia, pod kątem zastosowania do fitoremediacji w warunkach naturalnych. Badania wykazały zróżnicowanie w stężeniach metali ciężkich w wodzie i osadach. Wyższe wartości zanotowano w osadach w porównaniu do wody. Zmniejszenie stężenia obu badanych pierwiastków zanotowano w osadach w dwóch z trzech badanych zbiorników w ciągu sezonu wegetacyjnego, co sugeruje możliwość ich absorpcji i akumulacji przez rośliny wodne. Oba badane gatunki zakumulowały pewne ilości Cd i Pb w częściach podziemnych i nadziemnych, jednakże T. angustifolia wykazała wyższy potencjał do translokacji Cd w porównaniu do P. australis. Ta ostatnia wykazała z kolei wyższy poziom akumulacji Pb w dwóch jeziorach. Współczynnik translokacji był w większości przypadków wyższy w okresie wiosennym, w szczególności dotyczy to Pb dla obu badanych gatunków. Zwiększający się poziom indeksu ładunku zanieczyszczeń w osadach wzdłuż biegu rzeki Bogdanka wskazywał na akumulację badanych pierwiastków.
