    Opis:
    Human disturbance is an important factor in forming vegetation. According to our hypothesis, anthropogenic activity and changes in the species composition of grass communities occur in the process of co-evolution. Understanding co-evolution, to better predict future changes in the entire ecosystem. Five grassland sites were selected with different methods of use and hence different anthropogenic disturbance regimes. The results show that the composition of grassland communities responds to the methods of their use. The needs and demands of our civilization are changing. Humans co-create plant communities the preservation of which depends on their use by humans.

    Opis:
    Sulfur dioxide and nitrogen oxide are health hazardous gases, which contribute to the formation of submicron acidic particulates. To reduce SO2 and NOx emission from the sintering flue gas, the combination of ammonia-Fe(II)EDTA solution scrubbing with Fe(III) electrolytic regeneration is proposed. The above method has the following advantages: direct conversion of NOx and SO2 to harmless N2 and SO4 2−, recovery of the by-product (NH4)2SO4), simultaneous removal of NOx and SO2 emission from flue gas in the reactor. The effect of the pH, initial Fe(II)EDTA concentration, and voltage on the desulfurization and denitration efficiencies was investigated using a bench-scale reactor. The maximal desulfurization and denitration efficiencies were 98% and 52%, respectively. The optimum parameters were pH ˃ 5.0, 2.1 V, and 0.05 mol·dm–3 Fe(II)EDTA concentration. SO2 and NOx removal from the sintering flue gas by ammonia-Fe(II)EDTA solution scrubbing combined with electrolytic regeneration was also demonstrated in a pilot-scale reactor.

    Opis:
    Gaseous emissions during thermal animal waste treatment in a meat production plant have been determined. A dry flue gas system with a multisectional bag filter was installed at a meat production plant. Animal waste was incinerated in a rotary kiln, the capacity of the plant was 700 kg/h. The average thirty-minute (1352 samples) emission values of volatile dust, total organic carbon (TOC), hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur dioxide (SO2), nitrogen oxide (NO), nitrogen dioxide (NO2) and carbon oxide (CO) were obtained during a study period of 1 month. Specific samples were collected to determine dioxin, furane, heavy metal, mercury, cadmium and thallium concentrations. Histograms of the obtained results were prepared, and the results were compared with the permissible emission levels defined by the European Union. Additionally, justification was provided when the observed values exceeded the levels defined by the European Union.

    Opis:
    The influence of air pollutants on visibility in Warsaw Agglomeration has been investigated. Following pollutants were considered: PM10, SO2, NO2 and O3, while meteorological parameters included: air temperatures (mean, minimum, maximum), solar radiation, relative air humidity, rainfall rates and wind speed. Initial analyses were performed with the use of principal component analysis (PCA). In next stages, the logistic regression (LR), the analysis of variance (ANOVA), one-way classification and a model path of generalized regression models (GRM) were applied. PCA analysis showed that in the cold season the visibility index depends on PM10, SO2, NO2 and the temperatures: T, Tmin, and Tmax. In the warm season, the index of visibility is mostly shaped by four elements: O3, T, Tmax and solar radiation. Logistic regression model indicated that in the warm season only two variables are significantly related to visibility: PM10 and relative humidity of air. Regularities in the cold season shown by the LR correspond with the conclusions from the PCA. Among meteorological conditions, the most important is air temperature, but only Tmax preserves the same direction of influence as the one pointed by the PCA model.

    Opis:
    The results of pilot plant investigations of simultaneous removal of NOx, SO2 and Hg from flue gas with ozone as the oxidizing agent and the spray tower absorber with NaOH solution as the absorbent have been presented. Flue gas was delivered into the pilot plant at the flow rate of 200 m3/h from the coal fired OP-430 boiler. The effectiveness of NOx removal was over 95% when the molar ratio O3/NO reached 2.0. Sulfur dioxide was practically completely washed out from flue gas in the absorber at the liquid-to-gas ratio 7.5 dm3/m3. The effectiveness of Hg removal in the studied system was approximately 80%. It was pointed out that CO concentration in flue gas could considerably increase the ozone consumption. The effect of carbon dioxide in flue gas on the chemistry of absorption due to hydroxides conversion into carbonates and bicarbonates was noticed.
