Bacteria associated with Zn-hyperaccumulators Arabidopsis halleri and Arabidopsis arenosa from Zn-Pb-Cd waste heaps in Poland as promising tools for bioremediation.

To identify metal adapted bacteria equipped with traits positively influencing the growth of two hyperaccumulator plant species Arabidopsis arenosa and Arabidopsis halleri, we isolated bacteria inhabiting rhizosphere and vegetative tissues (roots, basal and stem leaves) of plants growing on two old Zn-Pb-Cd waste heaps in Bolesław and Bukowno (S. Poland), and characterized their potential plant growth promoting (PGP) traits as well as determined metal concentrations in rhizosphere and plant tissues. To determine taxonomic position of 144 bacterial isolates, 16S rDNA Sanger sequencing was used.

An Alliance of - bv. -Mycorrhizal Fungi From an Old Zn-Pb-Cd Rich Waste Heap as a Promising Tripartite System for Phytostabilization of Metal Polluted Soils.

The Bolesław waste heap in South Poland, with total soil Zn concentrations higher than 50,000 mg kg, 5,000 mg Pb kg, and 500 mg Cd kg, is a unique habitat for metallicolous plants, such as L. The purpose of this study was to characterize the association between and its microbial symbionts, i.e.

Variability in inorganic As, Sb and Tl species concentrations in waters and bottom sediments of the Kłodnica River (Poland).

The study describes the application of new methodologies for the simultaneous determination of As(III)/As(V), Sb(III)/Sb(V) and Tl(I)/Tl(III) ions in waters and bottom sediments of the Kłodnica River (Poland) with the hyphenated technique of high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS) . Time and spatial correlations were determined in the changes of total and speciation concentrations of the above-mentioned analytes in Kłodnica river in 2012. The developed methodologies demonstrate high selectivity and limits of quantification at the level of 0.

Impact of the Pb and Zn ore mining industry on the pollution of the Biała Przemsza River, Poland.

The development of mining and metallurgic industries of Pb and Zn ores in the Biała Przemsza catchment area has had a strong influence on the condition of the surface water and bottom sediments. In the following study, total contents of metals and metalloids were researched in the water and bottom sediment samples from the Biała Przemsza River. The samples were collected monthly in 2014 at five sampling points along the river.

Chemometric and environmental assessment of arsenic, antimony, and chromium speciation form occurrence in a water reservoir subjected to thermal anthropopressure.

In the study, arsenic, antimony, and chromium concentrations and selected physicochemical parameters in water and sediment samples from the thermal anthroporessure subjected Rybnik Reservoir (Poland) were determined. As(III), As(V), Sb(III), and Sb(V) ions were successfully separated on Dionex IonPac AS7 column, and Cr(III) and Cr(VI) on Dionex IonPac AG7 column. The obtained limits of detection were 0.

Development and validation of HPLC-ICP-MS method for the determination inorganic Cr, As and Sb speciation forms and its application for Pławniowice reservoir (Poland) water and bottom sediments variability study.

The optimization of methodology for determination and extraction of inorganic ionic As(III)/As(V), Cr(III)/Cr(VI) and Sb(III)/Sb(V) forms in water and easily-leached fractions of bottom sediments by HPLC-ICP-MS were studied. In paper total concentration of As, Cr, Sb, pH and redox potential were determined. Ions were successfully separated on Dionex IonPac AS7: As(III), As(V), Sb(III), Sb(V) and Dionex IonPac AG7: Cr(III), Cr(VI) with LOD 0.

Application of hyphenated techniques in speciation analysis of arsenic, antimony, and thallium.

Due to the fact that metals and metalloids have a strong impact on the environment, the methods of their determination and speciation have received special attention in recent years. Arsenic, antimony, and thallium are important examples of such toxic elements. Their speciation is especially important in the environmental and biomedical fields because of their toxicity, bioavailability, and reactivity.

A study on the seasonal mass closure of ambient fine and coarse dusts in Zabrze, Poland.

Diurnal samples of PM(2.5) and PM(2.5-10) were taken in an urban background area in Zabrze (Upper Silesia in southern Poland) in the winter (January-March) and summer (July-September) of 2009.
