    Opis:
    Pollution with heavy metals and waters in Mitrovica with surroundings, both in the past and in present days, is a preoccupation for the citizens of Mirtovica, as well as for the other inhabitants living around it. Such a problem has been a concern which still continues for a number of researchers who have been dealing with this issue, and who still continue to be preoccupied with the issue of heavy metal (habitat) pollution in this part of Kosovo. Heavy metal's contamination of the environment's main components, dates back to the 1970s/90s to this date. This pollution, especially of the rivers, is due to the industrial activity taking place in the Trepça Combine and the presence of industrial landfill sites of this Combine near the flow of two main rivers: the Sitnica and Ibër River waters, in the city of Mitrovica. The focus of our study, this time consists solely in the research and illumination of pollution with these heavy metals and waterworks of the Ibër River, as a result of the pollution caused by the industrial waste landfill located in Kelmend village. In the paper, we have attempted to show the concentration of heavy metals in sediment and water, by pointing at four sample sites of the Ibër river: in the Bosniak U1 neighborhood, then in the flow in front the U2 landfill, discharge flows from landfill U3 and a certain distance from the U4 landfill.

    Opis:
    The development of industry, agriculture, and transport contributes to an increased environmental pollution by heavy metals. The aim of the study was preliminary assessment of the contents of selected metals (lead, cobalt, copper, chromium, cadmium and nickel) in the sediments of Bug river. The study comprised part of the river flowing through Poland. It was found that the Bug river sediments are not contaminated in respect to the content of tested metals. Based on the analysis of the study results, these metals can be lined up in the following order: Cr > Pb > Cu > Ni > Co > Cd. Statistical analysis showed that copper and chromium occur in Bug river sediments in forms bindings with organic matter in majority of cases. The granulometric analysis of sediments from Bug river revealed the largest percentage of two fractions: 1.0–0.2 mm with average of 47.7 ± 19.77% and 0.2–0.1 mm with average of 20.6 ± 7.7%. These are the dominant fractions with the accumulation of metals in river sediments, which has been confirmed by statistical analysis.

    Opis:
    The concentration of Cu, Pb, Zn and As in water, sediment and muscle of Oncorhynchus mykiss from the Tishgo river in the central Andes of Peru were analyzed. The water, sediment and fish samples were collected from 36 sites in three sampling sectors. The analytical determination was performed by flame atomic absorption spectrophotometry. The mean Pb concentrations in the water from the three sampling sectors showed significant differences (p < 0.05) which exceeded the values of the Peruvian standard and the WHO. The mean concentrations of Cu, Pb and As in sediment did not present significant differences (p > 0.05) in the three sectors evaluated. The redundancy analysis (RDA) revealed that the concentrations of As and Pb in water, and Cu, As and Zn in sediment significantly influence the concentration of these elements in the O. mykiss muscle. The mean concentrations of Cu, Pb, Zn and As in the O. mykiss muscle were lower than those established by international regulations. Therefore, the concentrations of heavy metals and As recorded in this study do not represent a threat to the consumption of O. mykiss from the Tishgo river.

    Opis:
    The Dombivli city near Mumbai has rapid industrialized. However the improper environmental planning has resulted in discharge of industrial waste effluents from the industrial belt into the Ulhas River. These wastes from these industries include various toxic heavy metals which subsequently accumulate in the sediments of Ulhas River. This day by day increasing tremendous pollution load has provoked us to carry the systematic and detailed study of heavy metal content in the sediment samples collected along the Ulhas River along the Dombivli City, near Mumbai. The study was conducted in year 2012 and 2013. The study was carried out in along the banks of Ulhas River near the discharge of effluents from Dombivli Industrial belt Phase I and Phase II. Accordingly the sampling points were identified. The analysis for the majority of the toxic heavy metals like Cadmium (Cd), Copper (Cu), Nickel (Ni), Chromium (Cr), Cobalt (Co), Iron (Fe), Lead (Pb), Mercury (Hg), Arsenic (As) and Zinc (Zn), in sediment samples was done. From the results of our study, it can be concluded that there is a need of systematic and regular monitoring of pollution level along the Ulhas River so as to generate the data on accumulation of heavy metals in the river sediments which will further help in improving the industrial waste treatment technology adopted along the Dombivali industrial belt. It is expected that such scientific studies will help to gauge the extent of pollution in order to avoid long term irreparable damage to the ecosystem.

    Opis:
    The pollution of rivers from human activities such as housing, markets, workshops, transportation, land cultivation, and industry has become an issue. The increasing contribution of heavy metals to pollution in rivers has a direct effect on the metal bioaccumulation in fish. Therefore, this study aimed to examine the concentrations of Cd, Cu, and Pb in the waters, sediment, and fish harvested from the Krueng Sabee River, Aceh Province, Indonesia. Furthermore, the water, sediment, and fish samples were collected from six locations representing the upstream and downstream regions of the river. Cd, Cu, and Pb were analyzed using Atomic Absorption Spectrophotometry (AAS). The results showed that Cd, Cu, and Pb were not detected in the water, while the concentration of Cd in the sediments ranges between 0.0544 to 0.2683 mg kg-1, Cu ranges between 4.4149 to 14.8160 mg kg-1, and Pb ranges between 0.9186–15.4954 mg kg-1. Therefore, Cd, Cu, and Pb in the water and sediment were below the quality standard, but these heavy metals in the fish sample met the threshold limit. The highest Cd concentration was reported in Tor soro (5.5591 mg kg-1), and the highest concentration of Cu was reported in Mugil cephalus (6.7021 mg kg-1), while the higher Pb concentration was reported in Cyclocheilichthys Apogon (0.0279 mg kg-1).

    Opis:
    Overbank sediment profiles of the channelized and heavily polluted Vistula and Odra rivers were investigated in southern Poland. The sediments are usually represented by sandy layers about a dozen centimetres thick, intercalated with black sandy muds few centimetres thick and rich in organic matter. Accumulation of these sediments started by the end of 19th century. The sediments are contaminated with heavy metals in amounts exceeding background values by two orders of magnitude and contain coal particles dispersed in black layers. These fine sediments initially accumulated over gravel bars at the channel banks due to lateral channel stabilization by stony groynes and bank revetments, constructed in 19th and 20th century. Progressively the sediments, which are up to 4 m thick, became a part of 20–30 m wide floodplain zones along many reaches of the upper Vistula and Odra. The distribution of these sediments is related to the degree of channel narrowing and incision induced by 19th and 20th century channelization.

    Opis:
    Badaniami objęto 17 gatunków mięczaków słodkowodnych, z czego dla 14 gatunków oznaczono koncentracje metali ciężkich (Cu, Zn, Pb, Co, Cd i Hg) w tkankach miękkich, a dla 16 gatunków oznaczono stężenia tych pierwiastków chemicznych w muszlach. Łącznie dysponowano wynikami analiz koncentracji metali w 110 próbkach tkanek miękkich i w 119 próbkach muszli. Gatunkami, których tkanki miękkie i muszle najlepiej reagują na zmiany koncentracji metali ciężkich w wodzie i osadach dennych, okazały się: Anodonta anatina, Dreissena polymorpha, Lymnaea stagnalis, Pseudoanodonta complanata i Viviparus contectus. Drugą grupę, odzwierciedlającą w mniejszym stopniu poziomy metali w środowisku, stanowią cztery gatunki: Viviparus viviparus, Sphaerium solidum, Unio pictorum oraz Unio tumidus. Gatunkami najlepiej odzwierciedlającymi poziomy metali w środowisku w poszczególnych układach środowiskowych są: (1) tkanki - woda: Viviparus contectus, Anodonta anatina oraz Viviparus viviparus, (2) tkanki - osady: Anodonta anatina, Pseudoanodonta complanata i Viviparus contectus, (3) muszle - woda: Dreissena polymorpha, Unio pictorum i Lymnaea stagnalis, (4) muszle - osady: Viviparus viviparus, Dreissena polymorpha i Sphaerium solidum. W wodzie powierzchniowej wszystkie sześć badanych metali możemy kontrolować poprzez analizę muszli Dreissena polymorpha, a w osadach dennych Cu, Zn, Pb, Cd i Hg poprzez analizę tkanek oraz Co poprzez analizę muszli Anodonta anatina. Te dwa gatunki wydają się podstawowe do dalszych prac. Dwa gatunki uważa się za gatunki uzupełniające w dalszych pracach. Są to: Lymnaea stagnalis (w wodzie możemy kontrolować Cu, Zn, Pb, Cd poprzez analizę muszli, a w osadach Cu, Pb, Cd poprzez analizę muszli oraz Zn poprzez analizę tkanek), Viviparus contectus (w wodzie możemy kontrolować Cu, Co, Cd poprzez analizę tkanek i Pb poprzez analizę muszli, a w osadach Cu, Zn, Co i Cd poprzez analizę tkanek). W toku dalszych prac należy zrezygnować z gatunków, które od 2001 r. są na liście gatunków chronionych w Polsce. Są to: Sphaerium rivicola, Sphaerium solidum, Unio crassus, Pseudoanodonta complanata oraz Anodonta cygnea.
    The research was applied to 17 species of freshwater molluscs, for 14 species the concentration of heavy metals (Cu, Zn, Pb, Co, Cd and Hg) was marked in soft tissues, and for 16 species the concentration of these metals was marked in shells. This study is based on the analysis of 110 samples of soft tissues and 119 samples of shells. The species that best react to the changes in concentration of the heavy metals in water and sediments are: Anodonta anatina, Dreissena polymorpha, Lymnaea stagnalis, Pseudoanodonta complanata and Viviparus contectus. The second group, which is less related with the environment, are four species: Viviparus viviparus, Sphaerium solidum, Unio pictorum and Unio tumidus. The species most related with the environment in individual arrangements are: (1) tissues - water: Viviparus contectus, Anodonta anatina and Viviparus viviparus, (2) tissues - sediments: Anodonta anatina, Pseudoanodonta complanata and Viviparus contectus, (3) shells - water: Dreissena polymorpha, Unio pictorum and Lymnaea stagnalis, (4) shells - sediments: Viviparus viviparus, Dreissena polymorpha i Sphaerium solidum. In the surface water we can control all six analyzed metals through the shell analysis of Dreissena polymorpha, and in the bottom sediments we can control the concentration of Cu, Zn, Pb, Cd i Hg by soft tissues analysis and Co by shell analysis of Anodonta anatina. These two species are crucial for the future research. Two other species are considered as supplementary. Those are: Lymnaea stagnalis (in water we can control the concentration of Cu, Zn, Pb, Cd by shell analysis, and in sediments we can control Cu, Pb, Cd by shell analysis and Zn by soft tissue analysis), Viviparus contectus (in water we can control the concentration of Cu, Co, Cd by tissues analysis and Pb by shell analysis, and in sediments we can control Cu, Zn, Co i Cd by tissues analysis). In the future research one should resig from using five species that are under protection in Poland since 2001. Those are: Sphaerium rivicola, Sphaerium solidum, Unio crassus, Pseudoanodonta complanata and Anodonta cygnea.

    Opis:
    The study involved 17 species of freshwater molluscs. The concentration of heavy metals (Cu, Zn, Pb, Co, Cd andHg) in soft tissues was determinedfor 14 species, while the concentration of heavy metals in shells was determinedfor 16 species. Totally, 110 samples of soft tissue and 119 samples of shells were analysed. The statistical analysis of the qualitative data concerning concentration of metals in shells indicated a clear distinction between snails and bivalves. The only exception is Unio crassus, which was assigned to a three-point cluster together with snails. With respect to snails, this may be because the analysis was performed only on one sample. The results of this study can be significant both for palaeontological research and palaeoenvironmental research. If we have a few shell fragments available, it can be generally concluded, based on geochemical analysis of heavy metals in shells, which shell fragments belong to bivalves and which to snails. It is also possible to assess geochemical conditions of ancient ecosystems. Obviously, the given results are preliminary and they suggest necessity of further research.
