Progressing urbanization results in the potential increase of pollution sources such as wastes, industrial or municipal sewage, which may contain hazardous inorganic pollutants such as e.g. metal ions and their compounds. Urbanization has a negative effect also on soil, as a consequence of an increasing share of impermeable surfaces such as pavements, parking lots, housing developments and public buildings. The area of a hardened (impermeable) surface is exposed to intensive surface runoff during rain and as a result pollutants are transported through the storm drainage system directly to surface waters. The aim of this study was to determine the effect of metals contained in rainwater discharged from subcatchments of various land use types on the quality of surface waters (the Cybina River and the Antoninek reservoir) in the city of Poznań, as well as investigate whether metal contents in rainwater effluents depend on the relief and character of the immediate catchment. Investigations were conducted in 2009 along the lower section of the Cybina River. Water samples from the river and reservoir were collected each time when collecting rain water samples. Water and sewage samples were collected 15 times within a year. Analyses were conducted on 5 selected catchments (with different land uses) drained by storm water drainage system discharged to the Cybina River and the Antoninek reservoir. Water was collected from 13 sampling points (5 of which were sewer outfalls and 8 were situated on the river or the reservoir above and below the sewage discharge). Higher concentrations of all tested elements were recorded in rainwater in comparison to the water samples coming from the river or the reservoir. Canonical Variate Analysis (CVA) model presenting differences between water concentrations of Cu, Zn, Cd, Pb and Fe and environmental variables (rainfall intensity measured in a four-point scale, location as divided into industrial areas multi- and single-family housing as well as location of sewage discharge to the river on the reservoir) showed elevated concentrations of these elements especially in water collected directly from the storm water sewer. Elevated metal concentrations in storm system effluents did not have a significant effect on the content of these pollutants in the river or the reservoir. It could have been caused by the intensive immobilization of elemental ions in bottom deposits followed by the metal uptake by aquatic organisms, mainly plants.

The authors in the article presented information on the possibility of separating rainwater from municipal sewage and the possibilities of its re-use. They based their considerations on the experience of municipalities in the European Union (EU), the Dutch one in particular. The choice of the Dutch municipality of Apeldoorn was not coincidental. Apeldoorn has the highest rainfall level in all of the Netherlands. What is more, The Netherlands is one of those European countries that is highly advanced in water management. This is due to the fact that it is a small country with a very dense population, which must deal with the distribution of water resources for very populated municipalities. Moreover, 50% of this country is situated below the sea level, which causes problems with excess water in coastal provinces. The Dutch are therefore trying to manage water using all technical and legal possibilities. This article presents some solutions related to the separation of rainwater from municipal sewage and the financial possibilities offered by the municipality of Apeldoorn. The authors also shortly presented history of the use of rainwater, including Polish experiences. The authors applied research methods based on examination of documents in the municipality of Apeldoorn and interviewed municipal employees responsible for the project of separation rainwater from sewage.

The input of rain water to the forest floor and the composition of rainfall and throughfall water were monitored between October 2001 and September 2002 in a natural and two plantation (Eucalyptus globulus and Cupressus lusitanica) forests at Munesa, southeastern highlands of Ethiopia. The proportions of throughfall to annual incident rainfall that passed through the different forest canopies were 53% under Cupressus and the natural forest and 82% under Eucalyptus. Annual nutrients deposition by rainfall varied from 0.08 kg ha-1 yr-1 for Mg to 3.79 kg ha-1 yr-1 for Na. Wash-off of materials deposited on the canopy surface and leaching of intracellular solutes from the canopy resulted in an enrichment of throughfall fluxes in K, Mg, Ca and Cl relative to rainfall and varied among forest types, being highest under natural and Eucalyptus forests and lowest under Cupressus. Sodium, NO3–N, NH4–N, SO4–S and PO4–P fluxes in throughfall were depleted relative to rainfall, but the magnitude of net depletion was different for the different elements; highest for Na (3.87 kg ha-1 yr-1) followed by NH4–N (2.85 kg ha-1 yr-1) and lowest for PO4–P (0.42 kg ha-1 yr-1). The amount of canopy uptake and leaching were generally low in the dry season and increased sharply towards the wet season.

W artykule przeanalizowano stosunki wodne w profilu zielonego dachu w okresie wegetacji roku hydrologicznego 2008. Dzięki możliwości systematycznych pomiarów wilgotności aktualnej w 15 cm warstwie powierzchniowej profilu oraz ich weryfikacji na tle danych meteorologicznych stworzono podstawy do oceny badanego profilu pod kątem możliwości gromadzenia wody opadowej. Wyniki badań dowodzą, iż w okresie wegetacji roku hydrologicznego 2008, przy normalnych warunkach meteorologicznych, zapasy wilgoci [Z] w okresie wczesnej wiosny oraz po nawalnych opadach dochodziły do poziomu pełnej pojemności wodnej (57,8 mm). Podczas okresu pomiarowego obserwowano kształtowanie się zapasów wody na poziomie niższym od pojemności okresu suszy (POS), ale nigdy nie odnotowano ich spadku poniżej punktu trwałego więdnięcia roślin (PTWR).
