Glucosinolates (GLS), antioxidative compounds, total radical scavenging activities (TRSAs) and proteins of white cabbage samples derived from different regions of Europe, collected in the spring and autumn, were studied. Glucobrassicin and sinigrin were the dominating GLS in all analyzed cabbage samples. Depending on origin, these two GLS accounted for 30%(More)
The sensitivity of Heterocypris incongruens to selected heavy metal ions is discussed. Although the Ostracodtoxkit ® has been present on the market for a few years, data on its selectivity and sensitivity to toxicants is scarce; such data is indispensable when interpreting the results of sediment toxicity. The LC(50) and EC(50) results with the(More)
Due to a continuous demand of land for infrastructural and residential development there is a public concern about the condition of surface soil near municipal solid waste landfills. A total of 12 surface (0-20 cm) soil samples from a territory near a landfill were collected and the concentration of 16 PAHs and 7 PCB congeners were investigated in these(More)
A calibration procedure for solid phase microextraction-gas chromatographic (SPME-GC) analysis of organic vapours in air was described in which GC detector (MS in this case) signal is directly related to concentration of analytes of interest sampled by SPME. Gaseous standard mixtures used for the calibration were generated by means of a home-made(More)
In the present study, an analytical procedure was developed for the determination of short-chain fatty acids (SCFAs) in landfill leachate and municipal wastewater employing injection of aqueous samples to gas chromatograph with flame ionization detector (GC-FID). Chromatographic conditions such as a separation system, injection volume, oven temperature(More)
This work describes the problems that occur during routine multi-step determinations of polyaromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), which can be present at trace levels in water, and identifies sources of analyte losses at particular steps during the analytical procedure. PAH and PCB adsorption onto the walls of the container(More)
The paper presents the results of toxicity determinations carried out on sediment samples collected in the vicinity of the wreck of the German s/s Stuttgart (the southern part of the Gulf of Gdańsk, off the Polish coast) in relation to the determination of polycyclic aromatic hydrocarbons (PAHs). The toxicity of surface and core sediment samples was(More)
Urea-formaldehyde-resins bounded particleboards (100 x 40 mm plates) each from a different manufactory plant, were stored at room temperature, with free access of air. In selected time intervals plates were placed in the climatic chamber for five days, and formaldehyde (CH2O) emission were determined. The conditions were as follows: loading factor 1 m2/m3,(More)
The research presented concerns segments of capillary chromatographic columns of different types (WCOT, SCOT, PLOT) used as traps for collection of samples of volatile organic analytes from a stream of air utilizing the equilibrium denudation technique. During the model experiments (utilizing standard mixtures), values of the partition coefficients (Kfs)(More)
White, male Wistar rats were exposed continuously in chamber during 3 months on volatile organic compounds emitted from set of building and finishing materials used in living areas on ship. The air contamination was checked. The following tests for determination of combined toxic effects were performed: functional activity, the body and organ weights, basic(More)
