Red Fox, Vulpes vulpes L., as a Bioindicator of Environmental Pollution in the Countryside of Czech Republic

The objective of this study is to determine the accumulation of heavy metals in the tissues of the small intestines of red foxes from 4 different areas of the northern part of the Czech Republic. The red foxes were relocated from countryside and free nature to the neighborhood of big cities in the last two decades, so it could be great indicator of pollution in these four different areas, with the focus on countryside problems with pollution of heavy metals. The heavy metal (Cd, Pb, Cr, Cu, Zn, Mn, Ni) concentrations in 27 samples and the relationships between heavy metal concentration in red fox tissue and the location of sample were investigated. The highest concentrations of Pb (0.684 mg.kg–1), Cr (0.162 mg.kg–1), Ni (0.235 mg.kg–1) and Zn (19.76 mg.kg–1) were found in tissues from mountain areas. The highest concentrations of Cd (0.047 mg.kg–1), Cu (1.474 mg.kg–1) and Mn (2.025 mg.kg–1) were measured in tissues from industrial agglomeration around the city Hradec Králové. Pb and Cr concentrations in tissues of red foxes from two areas (environs of the city Krasna Lipa and Hradec Kralove) exceeded the permissible food consumption limits.

AbstractMesocestoides litteratus (Batsch, 1786) (Cestoda: Cyclophyllidea: Mesocestoidae) is a common parasite of the red fox (Vulpes vulpes) and other carnivores across Europe. There has been considerable debate as to the validity of M. litteratus and other closely related, often sympatric species of Mesocestoides. We examine isolates of M. litteratus from red foxes in the Czech Republic, Slovakia and Spain both morphometrically and by characterization of 18S rDNA. Morphometric ranges of all isolates confirmed their identity as M. litteratus and were usually within the range published formerly. The sequences of 18S rDNA of one or two isolates from each country were analysed. The sequences were the same and distinct from all published Mesocestoides 18S sequences with the exception of tetrathyridia from a lizard in the Czech Republic, which was identical to those of M. litteratus.

: The differences in Pb and Cd accumulation capabilities of Salix miyabeana, S. viminalis, S. × blanda, and S. elbursensis derived from willows planted in 1997 in coal-ash settling localities in the Krušné hory Mts.,the Czech Republic, were determined. Plantlets micropropagated by organogenesis were grown in sterile hydroponic media supplemented with 0.5mM Pb(NO3)2 or 0.5mM Cd(NO3)2· 4H2O. The samples of roots and aboveground parts were collected after 48, 72, 96, and 168 h of cultivation. Generally, substantially higher concentrations of accumulated Pb and Cd were identified in roots than in aboveground parts of all willow clones, even if clonal differences in their accumulation were detected. The results sufficiently confirmed the clonal differences in the uptake and translocation of heavy metals in the above-mentioned willows.

The article focuses on the study of change of containing heavy metals (zinc, copper, iron, cadmium, lead, arsenic) in the abiotic and biotic components of the Serepok river (Vietman) influenced by wastewater discharge from industrial areas. Heavy metal content was determined in the river water and bottom sediments in the four zones: above and within the boundaries of industrial regions Xoa Phu and Tam Thang and in two water reservoirs situated below the boundaries of those industrial areas. Tilapia Galilean ( Sarotherodon galilaeus ), Hemibagrus ( Hemibagrus ), and sazan ( Cyprinus carpio ) caught in these areas were the hydrobionts under study in which liver, gills, skeleton and muscles accumulation of heavy metals was detected. In the organs of fish caught in the river within industrial region, heavy metals concentration was 3-7 times higher. The greatest concentration of heavy metals was found in the liver and gills of fish caught in the boundaries of industrial regions, the least concentration was in the muscles. In most cases, significant correlation between heavy metal concentration in organs of fishes and in river water, bottom sediments has been revealed.

Removal Of Heavy Metals

A calcium bentonite from Orasu Nou deposit (Satu Mare Romania) was used as raw material. We have conducted laboratory experiments to determine the influence of bentonite on the degree of heavy metal retention. It has been observed that the rate of retention increases as the heavy metal concentration decreases. Experimental studies have been carried out on metal retention ( Zn) in bentonite. In this paper, we realized laboratory experiments for determining the influence of metal (Zn) on the growth and development of two types of plants (Pelargonium domesticum and Kalanchoe) and the effect of bentonite on the absorption of pollutants. These flowers were planted in unpolluted soil, in heavy metal polluted soil and in heavy metal polluted soil to which bentonite was added to observe the positive effect of bentonite. It has been noticed that the flowers planted in unpolluted soil and polluted with heavy metals to which bentonite has been added, the flowers have flourished, the leaves are still green and the plants whose soils have been polluted with heavy metals began to dry after 6 days, three weeks have yellowish leaves and flowers have dried. Experiments have demonstrated the essential role of bentonite for the removal of heavy metals polluted soil.

In this study, the geochemical properties of heavy metal-contaminated soils from a Korean military shooting range were analyzed. The chemical behavior of heavy metals was determined by analyzing the soil pH, heavy metal concentration, mineral composition, and Pb isotopes. In total, 24 soil samples were collected from a Korean military shooting range. The soil samples consist of quartz, albite, microcline, muscovite/illite, kaolinite, chlorite, and calcite. Lead minerals, such as hydrocerussite and anglesite, which are indicative of a transformation into secondary mineral phases, were not observed. All soils were strongly contaminated with Pb with minor concentrations of Cu, Ni, Cd, and Zn. Arsenic was rarely detected. The obtained results are indicated that the soils from the shooting range are contaminated with heavy metals and have evidences of different degree of anthropogenic Pb sources. This study is crucial for the evaluation of heavy metal-contaminated soils in shooting ranges and their environmental effect as well as for the establishment of management strategies for the mitigation of environmental risks.

Over the past two decades, the coastal waters of Jinhae Bay have been extensively used by coastal communities and industries for the disposal of domestic and various industrial wastes, therefore increasing the level of pollutants in coastal waters with a subsequent increase in sediments, especially of heavy metals. Specific objectives of this research are to investigate the distribution of heavy metal concentration in biota, to compare the concentrations with those in sediment and water and to relate the bioconcentration to the different heavy metals in biota obtained from several sites. Sixty one percent of heavy metals was found in particulate form during the high runoff season and 32% during the dry season. The behavior of the particulate metals after flowing in to the enclosed coastal sea is an important factor in heavy metal contamination. Copper, lead and chromium contamination of sediment was revealed at several sites. The bioconcentration factors (BCFs) of zinc, cadmium, copper, nickel, chromium and lead by the mussel (Mytilus edulis) were determined as 2,900, 2,814, 807, 423, 228 and 127 in the decreasing order, respectively. The areas located nearest to highly populated city and industries exhibited mussels with the largest accumulation of copper, lead and chromium.

Several experiments were carried out to study heavy metal tolerance in tissue cultures or whole plants of S. grandiflora., Callus was induced and maintained on modified Murashige and Skoog, 1962 medium (MS) supplemented with (0.5)mg/l benzyl adenine and (2)mg/l 2,4-phenoxy acetic acid . Heavy metals (Cd, Co, Cu, Cr or Zn) were added to the culture medium at different concentrations as contamination agents. In order to asses the effect of these heavy metals on seed germination; seeds were sown in soil contaminated with different concentrations of heavy metals for 3 weeks. Atomic Absorption Spectrophotometer was used for analysis of samples taken from whole plants and callus cultures. Results showed that callus fresh weight decreased with increasing heavy metal concentration in cultural medium. Germination percentages and plant heights increased over time. However, a reduction occurred in these parameters with increasing heavy metal levels. Percentages of metals accumulated in calli were (0.001, 0.011, 0.012 and 0.013%) at (0.0, 0.05, 0.075 and 0.1)mg/l Cd respectively; (0.001, 0.008, 0.016 and 0.006%) at (0.0, 0.1, 0.25 and 0.5)mg/l Co respectively; (0.001, 0.020, 0.034 and 0.015%) at (0.0, 0.075, 0.2 and 0.5)mg/l Cu respectively; (0.001, 0.013, 0.012 and 0.010%) at (0.0, 0.25, 0.4 and 0.5)mg/l Cr respectively and (0.027, 0.051, 0.059 and 0.056%) at (0.0 , 0.75, 1.0 and 1.5)mg/l Zn respectively. Percentages of metals accumulated in whole plants were (0.08, 0.55, 1.11, 0.83 and 0.44%) at (0.0, 1.0, 2.0, 3.0 and 4.0)mg/Kg soil Cd respectively; (0.11, 0.22, 0.55, 0.47 and 0.44%) at (0.0, 15.0, 30.0 45.0 and 60.0)mg/Kg soil Co respectively; (0.01, 0.10, 0.57, 0.58 and 0.72%) at (0.0, 25.0, 50.0, 75.0 and 100.0)mg/Kg soil Cu respectively.

Heavy Metal Pollutants

In the South Coastal Forest area, West Sumatra, a luminous mushroom with the species Neonothopanus Sp. This research was conducted with the aim of seeing the effect of heavy metals on the bioluminescence reaction of luminous mushrooms. Starting from the effect of heavy metal concentrations on the intensity and inhibition coefficient of luminous mushroom biolumination. From the measurement results, the maximum intensity value of luminous mushrooms is 499.6 au occurring at a wavelength of 505 nm. At a wavelength of 505 nm, visible light is produced in green. The results obtained are in accordance with observations, because the light emitted by the glowing mushroom is green. If the concentration of heavy metals is greater, the intensity of the bioluminescent fungus (Neonothopanus sp) will decrease. The type of heavy metal affects the intensity of the fungus biolumination. The greatest decrease in intensity occurred in copper (Cu) and iron (Fe), zinc (Zn) and lead (Pb). If the heavy metal concentration is greater, the inhibition coefficient will be smaller. The greatest inhibition coefficient due to the presence of heavy metals occurs in copper (Cu) then iron (Fe), zinc (Zn) and the smallest is lead (Pb).
