Our paper evaluates the effectiveness of pollutant removal from stormwater in a semi-natural treatment plant and develops stochastic models of their transformations in a soil bed. The examined wastewater treatment facilities consisted of reduction chambers and a retention-infiltration reservoir. The following indicators of pollution were subjected to analysis: BOD₅, COD, total suspended solids, and chlorides. It was shown that COD, total suspended solids, and chlorides are the indicators that have the greatest impact on stormwater quality. However, the possibility of removal of the analyzed pollutants from stormwater is affected by the sedimentation process occurring in the reduction chambers and in the retention-infiltration reservoir, as well as by the process of infiltration through the soil bed. The developed models of pollutant transformation during wastewater infiltration through the bed were presented as the regression equations, where the selected pollution indicators in the filtrate were the dependent variable, while the analyzed pollution indicators in water from the retention-infiltration reservoir, coefficients of constant reaction kinetics determined for each variable, and the time of infiltration of wastewater through the soil bed were adopted as independent variables.

Recently, algae have become significant organisms for biological purification of wastewater since they are able to accumulate plant nutrients, heavy metals, pesticides, organic and inorganic toxic substances and radioactive matters in their cells/bodies. Biological wastewater treatment systems with micro algae have particularly gained importance in last 50 years and it is now widely accepted that algal wastewater treatment systems are as effective as conventional treatment systems. These specific features have made algal wastewaters treatment systems an significant low-cost alternatives to complex expensive treatment systems particularly for purification of municipal wastewaters. By this method 70 % of biological oxygen demand, 66 % of chemical oxygen demand, 71 % total nitrogen, 67 % of phosphorus, 54 % volatile solid and 51 % of dissolved solid was reduced.

As a result of examinations carried out, 16 strains of microorganisms able to grow on mineral media with methyl tert-butyl ether as the sole source of carbon and energy were isolated. Bacteria prevailed among the isolated microorganisms . The growth of microorganisms under laboratory conditions was long and accompanied by low biomass increase. Under the conditions of the experiment, the isolated microorganisms did not show any quantitatively measurable biodegradability of methyl tert-butyl ether (MTBE) under aerobic conditions. This requires far-reaching caution with respect to trading in MTBE-modified petrols in order to protect the natural environment in Poland against contamination with that hard-to-biodegrade substance.

In this review the most well-known examples of secondary effects and pollutants which occur in the particular elements of the environment (atmosphere, hydrosphere, soil and food products) are described. Very often pollution of the environment is characterized only by quantities of primary pollutants emitted to the particular elements of the environment. However, it is much more difficult to find any information on certain secondary effects and pollutants which can have a considerably higher influence on environmental degradation than the respective primary pollutants. This does not concern such well-known phenomena as acid rains, the greenhouse effect, depletion of the ozone layer in the stratosphere and smog. This paper also presents some less well-known secondary effects and pollutants such as sick building syndrome, dioxins formation during waste incineration, secondary pollution of water during water treatment, eutrophication of waters, food contamination during processing, and occurrence of PCB's in the environment.

The bacterial degradation of phenol by Alcaligenes xylosoxidans and Pseudomonas putida was studied in a laboratory-scale stirred tank bioreactor. Several kinetic experiments were employed to obtain values of kinetic parameters by applying nonlinear regression methods to differential kinetic models and integrated experimental data. The extra sum of squares for statistical tests of reliability of proposed kinetic models was attached. The values of kinetic parameters based on the Haldane substrate inhibition model for both strains were: μmax=0.347 h-1, Ks=21.5 mg/1 and K1=707 mg/1 for Alcaligenes and μmax=1.988 h-1, Ks=15.92 mg/1 and K1=197.7 mg/1 for Pseudomonas. The measured yield coefficients YX/s were in agreement with values commonly published in literature (0.3-0.8). Degradation rates up to 0.5 g/(l- h) were obtained.

This study discusses the occurrence of neoplasia in the Baltic clam Macoma balthica from the Gulf of Gdańsk in recent years and investigates potential relationships between toxic compounds in the environment and the presence of the cancer. The disease was identified at four sampling stations during 1999–2002. Comparison with previous results highlighted the substantial prevalence of the tumour between 1998 and 2002. The prevalence of the cancer was strongly dependent on the sampling location (p < 0.001): it was highest at sampling point H45 (the deepest part of the gulf) and lowest at station PB30 (central part of the gulf). Monthly studies showed a trend towards an increasing prevalence of neoplasia during the warm months. However, over several sampling months no strong statistical correlation between the prevalence of the disease and the sampling time was found. The results of the study suggest that several environmental factors may promote the progress of the cancer in M. balthica from the Gulf of Gdańsk: it is most probably an indirect effect of pollution, although causality cannot be proven at this stage. Seriously polluted and exhibiting a considerable asymmetry of contamination, the ecosystem of the gulf provides an ideal environment for testing potential cause-effect relationships between pollutants and their biological effects.

Both sewage sludge and fly ash are wastes. Their granulation can decrease their adverse effect. Due to the contents of biogens in the sewage sludge the granulates will have fertilizing and soil-forming properties. The aim of this study was to find such proportion of components used for production of ash-sludge granulates that would decrease the volume of extracted contaminants to meet the requirements of regulation [36] preserving their fertilizing properties. In our study two types of fly ash were mixed in various proportions with municipal stabilized sewage sludge. The obtained granulates were subjected to one- and three-stage elution tests. In the eluates the concentration of nitrogen compounds, phosphorus, magnesium, calcium and heavy metals was determined. The mixture with the same share of sewage sludge and fly ash proved to be of high fertilizing value at the same time.

Large areas worldwide are polluted by cadmium (Cd) and lead (Pb). The objective of this study was to develop and verify a simple model for phytoextraction of Cd and Pb. Consequently, a new model was developed based on soil and plant responses to Cd and Pb pollutants. Polluted soils were packed into some pots. Land cress and spinach seeds were germinated in the pots. Results showed the more Pb and Cd-tolerance of land cress compared to spinach. Land cress dry matter was about 50 times more than that of spinach at same contaminations. For spinach, there was a threshold soil Pb concentration (600 mg kg⁻¹), beyond which plant is more efficient to uptake Pb. Results also indicated that the proposed model with linear sorption isotherm can reasonably well predict the time needed for remediation of soil Pb. However, the model could not provide a reasonable prediction for Cd remediation.
