Opis:: The aim of the present study was the estimation of the phytotoxicity of soils amended with sewage sludge with relation to Sinapis alba L. The study was realized in the system of a plot experiment. Two kinds of sewage sludge: dewatered and anaerobically stabilized sludge with dry matter content of about 24%, and dewatered sludge “Palikal” with dry matter content of about 92%. The results indicate that the tested samples are toxic. Growth inhibition at the studied samples ranged from 70.45% to 100%.

Opis:: We have obtained eight degradable/biodegradable materials based on starch (certified compostable), sample 4–7, HDPE mixed with totally degradable plastic additive (TDPA), sample 2 and polyethylene with the addition of pro-oxidant additive (d2w), sample 1. Composition of sample 3 has not been reported. The materials have been tested as to the rate and character of their degradability/biodegradability in controlled composting conditions. Experiment explored also the effect of degradation/biodegradation of plastic bags on compost quality. The material of the original samples was subjected to assessment using the Nicolet 6700 FT-IR spectrometer, the outcome thereof was obtaining infrared spectra of the samples. For further specification the original samples were tested using the thermogravimetrical analysis. The texture of the foils at different stages of degradation is presented in the Scanning Electron Microscope (SEM) photographs. Plastic bags certified as compostable have degraded in laboratory conditions and their degradation had no impact on the quality and features of compost. Selected samples (4, 6) showed significant erosion on surface when subjected to the SEM analysis. Samples labeled (by their producers) as 100% degradable (samples 1, 2, 3) did not show any visual signs of degradation and the process of degradation had no impact on the quality and features of compost. Only one of the samples (sample 1) showed certain erosion of surface when submitted for the SEM analysis.

Opis:: The study was conducted to measure the emission from landfill in the years 2005– 2011. The results are used to diagnose the emissions of CH₄. The mean value of CH₄ in vol. % in the collection wells ranged from 0 to 2.14 vol. % the mean concentration of CH₄ in mg/m³ ranged from 0 to 25 251 mg/m³, the average concentration of CH₄ in mg/Nm³ at the measuring and control points ranged from 2.2 to 24.1 mg/Nm³. CH₄ emissions from the landfill do not exceed the reporting thresholds the landfill does not meet conditions for being included in the Integrated Register of Pollutants.
