Opis:
Phytoremediation is an acceptable, economical, and eco-friendly way to remediate the metal contaminated soils beside the industrial zone. Like other industries, the textile industries generate the effluent containing several types of pollutants such as metal conjugated dyes, several inorganic and organic substances, etc. When discharged to the environment, metals - specifically heavy metals - exert an adverse impact on soil and other biotas through the food chain. In this study, Bryophyllum pinnatum was used for phytoremediation in the contaminated soil sample collected from the area located around textile industries in Kaliakair, Bangladesh. The experiment was carried out by ex-situ in earthen pots. The concentration of six heavy metals including Zn, Cu, Ni, Cr, Pb, and Cd was analyzed before applying phytoremediation. Two heavy metals, Cu (28.57 µg/g) and Zn (143.88 µg/g) were found and others were not detected in that soil. After planting of Bryophyllum pinnatum, the concentrations of Cu and Zn in the contaminated soil were analyzed at three intervals of 45 days (S3), 90 days (S4), and 135 days (S5) in three replications. The experiment revealed that there was a decline in the concentration of Cu in soil (27.08 µg/g for 45 days and 13.19 µg/g for 90 days) except for the 3rd replication of 135 days (S5). However, the concentration of Zn (mean 103.09 µg/g) in soil was measured at 45 days and then remained within nearer values of concentration for other replications. The amounts of heavy metals uptake for both Cu and Zn by plants can be presented as leaves> stem >root which indicated that heavy metals were transferred from root to shoot over time. Bryophyllum pinnatum can, therefore, be considered as a good hyperaccumulator plant having BCF>1 and TF>1 values as well as possessing a better capacity of phytoextraction of metals.

Opis:
Landfills with the open dumping method cause many environmental pollution problems, such as pollution, soil, surface water, and groundwater. Pollution cleaning technology (remediation) to reduce the harmful effects in the locations contaminated with heavy metals can be implemented by means of several methods, including using phytoremediation as a barrier to heavy metal contamination in order to preventing contamination distribution to the environment. Ferns (phytoremediation) on the side of the open dumping landfill were investigated as phytoremediation, inhibiting the distribution of heavy metals into the environment. The descriptive-analytic research method was used to analyze the ability of ferns in an open dumping landfill in peatland areas as a barrier to metal contamination distributed to the environment. The results show that ferns can bind heavy metals, such as Hg and Pb, produced from open dumping landfill activities to prevent the distribution of heavy metals to the environment around the landfill. Ferns are able to block the distribution of heavy metals into the environment, especially Pb and Hg. The ability of ferns to become potential plants in peatland areas requires further testing of other heavy metals.

Opis:
The impact of adding a natural clay sorbent such as halloysite on the content of selected heavy metals in the biomass of common orchardgrass (Dactylis glomerata L.) was studied in a pot experiment. The study was conducted on mucky soil enriched anthropogenically with heavy metals, whose values exceeded permissible standards of soil quality and values of the geological background. The experiment included three variants with differentiated percentage of halloysite, i.e. 10%, 30% and 50%, as well as two control cultivations. The results confirm the impact of halloysite on the physicochemical properties of soil, consisting in increased soil pH and sorption capacity. Addition of halloysite to soil also differentiated the quantity of crop yield and concentration of heavy metals in the plant and soil. Halloysite was found to have an inconsistent impact on the concentration of heavy metals in the biomass of common orchardgrass, which was proven by some elevation in the level of heavy metals and a higher bioaccumulation factor (BAF). Halloysite constituting 50% of the mass of substrate substantially increased the consumption of Pb and reduced the sorption of Cr. Addition of halloysite stabilised Zn and Cu in soil. The results of our preliminary investigation indicate that addition of halloysite to soils with excessive concentrations of heavy metals influences the level of soil sorption to the extent which may be effective for soil remediation.

Opis:
Floristic composition in three industrial areas with soils contaminated by heavy metals (As, Cd, Cu, Hg, Pb, Zn) and organic pollutants (polychlorinated biphenyls) was studied. The content of Pb was only significantly correlated with the floristic composition and explained 13.8% of its variability considering spatial dependency of the sites. No correlation was found for PCBs. Altogether, 237 plant vascular species were found at three study sites (117, 133 and 105, respectively). The three study areas differed in their species composition represented by their own characteristic species. The gradient in the content of natives/non-natives, species number, prevailing life forms and indicator values for plant species investigated was revealed. Based on our results, for phytoremediation purposes we can select productive plant species with high biomass and ability to accumulate large amounts of heavy metals or organic compounds and surviving on soils with low mineral content.
