W artykule zaprezentowano wyniki badań według projektu „Ocena stężeń PAH i metali ciężkich na powierzchni hałd i obiektów przemysłowych" realizowanego w ramach Programu Operacyjnego Współpracy Transgranicznej Republika Czeska - Rzeczpospolita Polska przez VSB-TU w Ostravie oraz GIG (CZ 3.22/1.2.00/12.03398:2013). Badania na wybranych 20 obiektach (hałdach), po 10, po obu stronach granicy polsko-czeskiej w strefie przygranicznej Euroregionu Silesia wykazały, że pyły PM10 w warstwie przypowierzchniowej stanowią od 1,2 do 7,6 % zebranego materiału mineralnego. Ich skład mineralny związany jest z karbońskimi odpadami wydobywczymi oraz popiołami energetycznymi.

The article presents the results of the research done within project „Assessment of concentrations of WWA and heavy metals on the surface of dumps and industrial facilities" realized under the Operational Programme of Cross Border Cooperation of Czech Republic - Republic of Poland by the VSB-TU in Ostrava and CMI (CZ 3.22/2.1.00/12.03398:2013). The studies carried on 20 selected sites (waste dumps), 10 on each side of the Polish-Czech border, on the border area of the Silesia Euroregion, showed that PM10 dust in the near surface layer constitute between 1.2 to 7.6 % of the collected mineral material. Their mineral composition is related to the Carboniferous mining waste and fly ashes.

The results from the experimental research are presented in the abstract. The experimental research involved utilization of the sludge from the mine water treatment plant of Coal Quarry ČSA/Czechoslovak Army/ (hereinafter “ČSA”) and Coal Quarry Jana Švermy (hereinafter “JŠ”) in the segment of thermal insulation mortars. The mine water treatment is described below including chemical and mineralogical sludge composition as the additional component of the binding material in the polyurethane thermal insulation mortars. Furthermore the composition of experimental mixtures of the thermal insulation polyurethane mortar is presented in the work and its physical-mechanical properties. The monitored elements included the strength characteristics, heat conductivity coefficient λ, and water vapour diffusion coefficient μ.

Effect of column bleed on trueness of determination of trace levels of dibenzofuranes (PCDD/F) and biphenyls (PCB) by gas chromatography-high-resolution mass spectrometry (GC-HRMS) was studied. As a result of extensive bleed of an arylenesiloxane capillary column, fluctuations of abundance ratios of monitored ions were observed, making exact determination of target analytes impossible. These effects were observed on food samples as well as on pure standard mixtures. The column bleed affected the abundance ratios of PCDD/F and PCB within the range of 13–328 pg of target analyte/mL, and higher levels of analytes remained intact. An analysis of diluted calibration mixtures is recommended as a tool for detection of column bleed.
