The influence of temperature and pH of water on the development of chosen species of algae and cyanophytes (Cyanobacteria, Cyanoprocaryotes) causing water blooms in two dam reservoirs, was studied. Their mass development was observed in various seasons of the year. Each species preferred different environmental conditions. The dominating species of phyto-plankton varied in both reservoirs, only dinoflagellate Ceratium hirundinella being the exception.

The reservoir where the studies were carried out was originated by modification of an old oxbow lake of the Vistula River. The most important sources of inflowing waters are industrial waters from "Puławy Fertilizer Factory". The highest variability of concentration, was NH4 +-N and also Cl-, Ntot., and PO4 -3. Some significant correlations between chemical properties of water and algae (especially green algae and diatoms) were found, which suggested that this phytoplankton was mainly responsible for the biogeochemical cycles in the shallow, strongly polluted reservoir. Another interesting phenomenon was the statistically positive correlation between the density of cyanobacteria and potassium, which suggested that it may play an important role in their abundance.

Physicochemical parameters of water and phytoplankton composition were studied in the dimictic, submountain Dobczyce Reservoir (southern Poland) affected by summer stormflow, which took place in September 2007. During summer (except September) temperature, pH, dissolved oxygen, and carbonates showed vertical differentiation. Stormwater flow through the system had a destabilizing effect on summer stratification. It diluted the concentrations of salts (sulphate and chloride) and slightly increased the concentration of nutrients in the reservoir. In phytoplankton some changes in the dominant species among the Cyanobacteria group were noted.

Badano zmiany parametrów fizykochemicznych oraz strukturę fitoplanktonu w wodzie dimiktycznego, podgórskiego zbiornika zaporowego (Zbiornik Dobczycki, południowa Polska), przez który we wrześniu przeszła fala powodziowa. Temperatura wody, pH oraz zawartości tlenu rozpuszczonego i wodorowęglanów wykazywały znaczne zróżnicowanie w słupie wody w okresie lata. Fala wezbraniowa płynąca przez zbiornik we wrześniu zaburzyła letnią stratyfikację wykształconą w pelagialu. Spowodowała ona rozcieńczenie stężeń soli (chlorków i siarczanów) oraz niewielki wzrost zawartości azotanów i fosforu ogólnego. Porównując okres przed wezbraniem i krótko po przejściu fali powodziowej, w składzie fitoplanktonu stwierdzono zmiany w obrębie dominujących gatunków należących do sinic (Cyanobacteria).

Starorzecza Wisły w rejonie Spytkowic w dolinie górnej Wisły stanowią obszar chroniony Natura 2000 zagrożony wskutek napływu jej zanieczyszczonych wód. Przeprowadzone badania wód starorzeczy pokazują kilkukrotny wzrost zawartości chlorków, siarczanów, węglanów, fosforanów, azotanów, sodu, potasu, magnezu, wapnia oraz przewodności przy wyższych niż przeciętne stanach wody w Wiśle, chociaż powodzie powodują zmniejszenie koncentracji większości z tych składników. Również osady denne w części starorzecza, do której dopływa woda z Wisły, zawartości cynku, ołowiu i kadmu są przeciętnie 3 razy wyższe niż w jego części położonej poza wałami. Znacząca część kadmu, około 50-70%, pozostaje w formach łatwo przyswajalnych dla organizmów i może powodować ich kumulację w żerujących w dnie małżach.

The oxbow lake at Spytkowice in the upper Vistula River valley is a protected area Natura 2000 endangered by the inflow of contaminated Vistula waters. Investigations of waters of the oxbow lake exhibit multifold increase of chlorides, sulphates, carbonates, phosphates, nitrates, sodium, magnesium, calcium and conductivity at Vistula water stages higher than average however, floods effects in a dilution of these contaminants. Moreover, bottom sediments in parts of the lake affected by the Vistula water inflow are 3 times more contaminated with zinc, lead and cadmium, on average, than that behind flood dykes. The significant part of cadmium, about 50-70% occurs in form the most available for benthic organisms, which may cumulate in sediment-feeding mussels.

This investigation focused on plankton inhabiting fishponds, which previously received mine waters from the lead-zinc mine ‘Matylda’, located in southern Poland (Upper Silesia). The purpose of the investigation was to study the effects of chronic and persistent contamination of fishpond bottom sediments with heavy metals originated from the lead and zinc mine. The phytoand zooplankton in the four fishponds were dominated by diatoms, green algae and rotifers. Plankton composition of the reference non-contaminated pond was different, since Chrysophytes dominated, and Copepoda were the most numerous among zooplankton. In the contaminated fishponds, we observed teratological forms, both for phyto-and zooplankton species, but only as individuals. Our results showed that planktonic communities had adapted to chronic and persistent heavy metal contamination.

Przeprowadzono standardową analizę wody oraz określono zawartości metali ciężkich w wodach, osadach i wybranych gatunkach roślin, pobranych ze stawów oraz ze strumienia Matylda w rejonie dawnej kopalni rud Zn-Pb Matylda w Chrzanowie. Mimo niemal 40 lat od zamknięcia kopalni koncentracje Zn, Cd i Pb wodzie i roślinach są wciąż bardzo wysokie, a w osadach przekraczają nawet 1000 razy wartości tła geochemicznego.

Standard analyze of water and heavy metals content in waters, sediments and selected plant species were carried out in the fish ponds and the Matylda stream in proximity to former Zn-Pb ore mine Matylda in Chrzanów. Despite almost 40 years since closure of the mine, sediments, waters and plants are strongly polluted by Zn, Cd and Pb with sediment concentrations exceeding even 1000 times geochemical background.

Rotifer diversity was studied in three different types of artificial water bodies situated in one of the largest cities in Poland. The bodies of water were as follows: a fountain in a city park, the Nowa Huta dam reservoir, and the Bagry gravelpit. The lowest number of rotifer species (23) was noted in the urban fountain, and the highest (36) in the Bagry gravel-pit lake. Rotifers’ communities in the investigated water reservoirs showed different levels of diversity and density. The most numerous species in the dam reservoir was Trichocerca similis (2511 ind. l-1) and in the Bagry gravel-pit lake was Polyarthra dolichoptera (2634 ind. l-1). However, the most abundant species in the fountain was Brachionus urceolaris (863 ind. l-1). The highest values of Shannon and evenness diversity indices were found in the Bagry gravel-pit lake (H’ = 2.521, J’ = 0.783), while the lowest in the urban fountain (H’ = 0.568, J’ = 0.258). The DCA analysis (Detrended Correspondence Analysis) showed that the diversity of rotifers communities in the studied reservoirs was related to the concentration of magnesium and calcium, and to water conductivity.
