Opis:: The present study was aimed to identify the indigenous fungal strains which could possibly be applied to the bioremediation of heavy metal-contaminated soil. The contaminated soil samples of Korangi Industrial Estate Karachi were found to have total concentration of Cu 1.044 mgL1 , and Pb 0.631 mgL–1. A total of eight indigenous strains of the fungus were isolated and screened for bioremediation capacity from heavy metals-contaminated soil. For the bioremediation of Lead (Pb) these same indigenous eight fungal strains were used for biological remediation. All the fungal isolated with enhanced bioremediation capability were through phenotypic and genotypical characterization. The topology of the phylograms established that the fungal isolates used in this study were allocated to: K1 (Penicillium notatum), K2 (Aspergillus parasiticus), K3 (Aspergillus fumigatus), K4 (Aspergillus flavus), K5 (Aspergillus terries), K6 (Fusarium solani), K7 (Penicillium chrysogenum), K8 (Aspergillus niger), K9 (Penicillium piceum) and K10 (Penicillium restrictum). Thus, K8 fungal isolate was found to be more efficient with maximum bioremediation capacity, for copper and lead removal efficiency, and selected for FTIR and SEM to find out the uptake of Cu and Pb which of the functional groups are involved, and further to detect the effects of bioleaching of both heavy metals on to the surface of K8 fungus biomass. The current study indicates that indigenous fungal isolates could be used with high potency to remediate or clean up the heavy metals-contaminated soil either by the technique of in situ or ex-situ bioremediation.

Opis:: The present study was conducted to characterize the solid sludge from the Bahir Dar textile industry.The concentration of heavy metals (Cr, Cd, Zn, Fe, Pb, Cu and Mn) in the samples were found to be 37.433-50.967, ND, 244.8-279.9, 2868.633-2886.667, 4.567-7.83, 242.767-282.133 and 160.9-212.8 (mg/Kg) respectively. The range of the pH, EC (%), OM (%), OC (%), MC (%), VS (%) and FS (%) in the sludge samples were found to be in the ranges of 7.317-7.771, 1.466-1.872, 12.302-12.778, 7.136-7.412, 9.211-11.576, 44.598-47.778 and 52.222-55.402 respectively. The results of the heavy metals in the textile sludge sample showed that the concentration levels of Cu metal was above the standard guide lines for maximum limit proposed for agricultural soil set by FAO /WHO and in the case of other metals (Pb, Zn, Mn, Fe, Cr), their concentration levels were found below the standard guide lines for maximum limit proposed for agriculture soil set by this organization, but the concentration levels of Cd was not detected in this present study. Finally, the study concluded that pre-treatment process for reducing the amount of some heavy metal is mandatory before the sludge can be used as a soil conditioner / fertilizer in the agricultural soil.

Opis:: The aim of the study was to evaluate the species composition in the fallow lands in areas heavily degraded by the mining and processing industries. The research was conducted in the western part of the Małopolska province in the municipality of Trzebinia. The layer C of phytocenosis that is the green layer was analyzed by specifying its all plant species and by approximately estimating vegetation cover according to the modified Braun-Blanquet scale. 212 species of vascular plants were found in the research areas. Species typical of fallow lands and ruderal areas i.e. giant goldenrod, couch grass and bush grass are the dominant species in the study areas. Among the species found in the study areas the species typical of fresh meadows such as false oat-grass, goosegrass and sorrel as well as thermophilic species such as crownvetch, greater knapweed or cypress spurge appear with great frequency.

Opis:: The aims of this studies were: (i) to examine the influence of heavy metal content (Zn, Cd, Pb, Fe, Cu) and other physico-chemical soil parameters on the level of root colonization of Molinia caerulea and (ii) to relate root colonisation parameters and soil variables to Molinia caerulea abundance in two contrasting habitats (grasslands and heavy metal contaminated sites). The sites differ significantly in terms of bio-available heavy metal contents, particularly Zn (34 times more than grasslands), soil texture, CaCO_{3}, organic matter (LOI%), Mg and nitrate content. Principal Component Analysis showed the strong negative correlations between frequency of mycorrhization (F), arbuscular abundance (A%) and intensity of root cortex colonisation (M%) and concentration of bio- available Zn and Cd. Moreover, no positive correlation between root colonization of Molinia and its abundance was found. The frequency of mycorrhization of root fragments (F%) was only slightly dif- ferent between these two habitats, whereas the intensity of root cortex colonisation (M%) and relative arbuscular abundance (A%) were significantly lower (3 and 4 times respectively) on the post-industrial sites. The bioavailable Zn content in the substratum of post-industrial sites was strongly negatively correlated with species richness, Shannon diversity index and Evenness. In contrast, these relationships were not statistically significant in grasslands. Based on obtained results we could draw a model of possible relationships between root colonization of Molinia, HM content and Molinia abundance on grasslands and post-industrial sites. Bioavailable Zn content in the soil is a one of main factors influencing the Molinia community diversity. In the grasslands, lower amounts of bioavailable Zn, resulted in higher species richness (R) and species diversity (H) which in turn lead to higher root colonization. On the other hand, on the post-industrial sites, the elevated bioavailable Zn content strongly decreases the plant species richness (R) and species diversity (H) and this caused the decline in root colonization parameters. The low species richness on Zn-polluted sites allowed Molinia to reach higher abundance since the competition with other species is reduced.

Opis:: Badania prowadzono w wazonach kamionkowych umieszczonych w gruncie, które wypełniono glebą płową właściwą (wg WRB, Haplic Luvisols), wytworzoną z piasku gliniastego lekkiego na glinie lekkiej. Do gleby wprowadzono metale ciężkie w formie soli: ZnSO4, Pb(NO3)2 i Cd(NO3). Jednocześnie do gleby wprowadzono jednorazowo: nawóz organiczno-mineralny z węgla brunatnego „Rekulter”, węgiel brunatny, torf, obornik lub dolomit w dawkach odpowiednio 180, 140, 390, 630 lub 7 g na wazon, co odpowiadało 5 Mg Corg na ha. W doświadczeniu uprawiano żyto ozime na zieloną masę. W próbkach roślinnych oznaczono ogólną zwartość wapnia, magnezu, sodu, potasu, fosforu i azotu. Celem badań było określenie wpływu dodatku materii organicznej z różnych źródeł do zanieczyszczonej gleby na plonowanie żyta oraz zawartość i rozmieszczenie K, Na, Mg, Ca, P i N w życie. Wartość nawozowa substancji organicznej z różnych źródeł wyrażona plonem roślin była najwyższa dla Rekultera, a najniższa dla torfu. Dodatek substancji organicznej do gleby powoduje wzrost zawartości K, Mg, P i N w źdźble i kłosie żyta. Zawartość sodu w nadziemnych częściach żyta nie zależała od zanieczyszczenia gleby metalami ciężkimi i materii organicznej. Zawartość azotu w życie na glebie zanieczyszczonej była wyższa w porównaniu do roślin z gleby bez metali ciężkich.
The experiment was carried out in stoneware pots sank into the ground filled up with 56.4 kg of soil: Haplic Luvisols formed from loamy sand. The soil was mixed up with liquid form of salts: Cd(NO3)2, Pb(CH3COO)2 and ZnSO4. To the soil a brown coal preparation, so called “Rekulter”, brown coal, peat, farmyard manure, and dolomite were applied in the amount of 180, 140, 390, 630 and 7 g per pot, which is equivalent to 5 Mg of organic carbon per ha. Winter rye (Secale cereale) was harvested in green forage. The manurial value of organic substance originated from different sources expressed as the plants' crop was the highest for Rekulter and the lowest for peat. The addition of organic substance to soil contaminated with heavy metals causes the higher content of phosphorus in rye's roots. The content of sodium in the rye's above - the grounds parts did not depend from addition of organic matter to soil.

Opis:: The study was conducted on three specially prepared test areas along main streets of Bialystok. The experimental plots were sown with two lawn grass mixtures: Eko and Roadside, and three doses of sewage sludge 0.0 (control), 7.5 kg/m2 and 15.0 kg/m2 were used. The calculated bioconcentration factor made possible to determine the mobility of the various metals from the soil solution to the aerial parts of plants. The obtained results showed that the plants absorbed Cd, Zn, Cu easier than Pb and Ni suggesting a high mobility, in particular of Cd, Zn, Cu, and reflects the easiness extraction of those metals by plants. Significant correlations between concentrations of metals in soil and grass were observed, nickel in soil was significantly correlated with Cd, Zn and Cu in plants, while the Zn content in soil with the level of Cu in plants.
