Opis:: A high number of whitefish, Coregonus lavaretus, from Lake Thun, Switzerland, display gonad malformations. We tested the hypothesis that exposure to sediment-borne contaminants during the embryonic life results in the development of malformed gonads later in ontogeny. The investigated contaminants were 2,4,6-trinitrotoluene (TNT), which may leak from residues in the lake sediments as consequence of former ammunition dumping into Lake Thun, as well as sulfonated naphthalene formaldehyde condensates (SNFC), which are introduced into the lake from wastewater disposals of a nearby tunnel construction site. Experimentally, whitefish eggs were exposed during 52 days from fertilization until hatching to a) an artificial sediment (control), b) an artificial sediment spiked with TNT (0.5mg*kg-1 dry weight), c) SNFC compounds dissolved in water (3µg*l-1 of each naphthalene-1-sulphonate, naphthalene-2-sulphonate, naphthalene-1,5-disulphonate, naphthalene-2,7-disulphonate), and d) sediment from Lake Thun sampled in an ammunition dumping area. To mimic in situ exposure of the eggs to the sediment-water-interface under laboratory conditions, we developed a novel contact incubation technique. After hatching, fish were reared in tap water for three years until they reached sexual maturity, and were then examined for the presence of gonad malformations. No malformations were observed in the control, in the TNT and SNFC treatment groups. In fish incubated during the embryonic stage on Lake Thun sediment, 2 out of 117 adult males (1.7%) displayed malformed gonads, which is significantly lower than levels of gonad malformations in wild whitefish from Lake Thun (on average 29% in males, 12% in females). The results from our experiment provide no evidence that sediment contamination with TNT or SNFC compounds is a causative factor for the induction of gonad malformations in Lake Thun whitefish.

Opis:: The paper deals with sediments of anthropogenic reservoirs from the central part of the Katowice Upland. Over most of the area, the original relief was considerably altered due to many-years’ mining of hard coal, historical mining and processing of zinc-lead ores, smelting of iron and non-ferrous metals, and chemical and machinery industries. The changes in land surface give rise to mining collapse areas transformed to water reservoirs. Sediment samples (103 samples in total) were collected form artificial lakes, ponds and settling ponds. Samples were air-dried, sieved through a 0.2-mm nylon sieve and digested in aqua regia. Contents ofAg, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, P Pb, S, Sn, Sr, Ti, Vand Zn in the samples were determined by the ICP-OES method. Mercury content was measured using the CV-AAS method. To assess the extent of sediment contamination the Index of Geoaccumulation (Igeo) and the ecotoxicological (Threshold Effect Concentration and Probable Effect Concentration) criterion were used. The sediments show very different chemical compositions. The content of trace elements varies from values lower than the regional geochemical background of the Silesian-Cracow region to extremely high concentrations. Distribution of many toxic chemical elements is characterized by high spatial variability and a strong dependence on the location of pollution sources. About 60% of analysed samples were heavily contaminated due to the very high concentration of cadmium (up to 905.9 mg/kg), lead (up to 25,081 mg/kg) and zinc (up to 45,361 mg/kg) as well as arsenic (up to 2,220 mg/kg), chromium (up to 901 mg/kg) and mercury (up to 11.80 mg/kg). Due to the concentration of metals (TEC and PEC values) almost 80% of the sediments can be harmful to aquatic organisms, as well as to wild animals that consume them. The main cause of harm is the very high concentrations of cadmium, lead and zinc, less of silver, arsenic, chromium, copper and nickel.

Willow (Salix) is a very popular plant in Poland, a symbol of Polish country-side. It is used for weaving baskets, for production of wicker furniture and for reinforcement of river and lake embankments. It is also a pioneer plant in land reclamation process (dunes, excavations etc.). These practical applications of Salix were taken into account when a conception of willow plantations watered with sewage was developed. New application of Salix is using it as an energy resource. In the article the up to date experiences with application of willow for removal of pollutants from point and aerial sources and for sewage sludge utilization are described. At the zoo in Oliwa, along the bed of the Rynaszewski Stream, the main inflow of the Jelitkowski Stream, a set of 5 hygrophyte facilities was constructed for decreasing the load of organic nitrogen and elimination of faecal coli bacteria. The willow buffer zones were located at the edges of the ponds and along the stream bed. The willow buffer zones were located at the edges of the ponds and along the stream bed. The experiences show the buffer willow zones can be used for removal of pollutants from aerial sources. Laboratory experiments were carried out in order to evaluate the effectiveness of pollutants removal from sewage. The seedlings of willow (Salix viminalis) were grown in PE pots, filled with sand. The highest removal efficiency of pollutants (nitrogen, phosphorus, BOD5 and COD)was observed in the pots irrigated with biologically treated sewage and the lowest removal efficiency was observed for the pot without plants. Nine individual household WWTPs with horizontal flow of sewage (HF-CW), inhabited with Salix viminalis, working as the second stage of treatment were analysed. The plants were located near Ciechanow, Lublin and in Lubiejewo near Ostrołęka. On the basis of laboratory and field experiments it was proved that Salix viminalis can be applied for treatment of sewage in individual household treatment plants. Application of willow results in the increase of treatment efficiency in comparison to soil filters. Sewage sludge utilization in a willow plantation in the WWTP Swarzewo. The investigations were carried out at the pilot willow bed (2400 m2 area), planted with Salix viminalis. Sewage sludge from the WWTP Swarzewo was then discharged to the bed - in 3 years time the thickness of discharged sludge layer reached 1 m. Studies show willow plantations can be applied for sewage sludge utilization. In the years 2002÷2003 in southern Sweden the content of heavy metals in soil and biomass in several willow plantations was analysed. All analysed plantations had been irrigated with sewage sludge in the past. The assimilability of metals by the aboveground tissues of willow was analysed with regard to the content of metals in discharged sludge. It was found out that in case of cadmium the uptake by plants was 10 times higher than the content in sludge. On the basis of investigation results and statistical analyses it was postulated that the yearly doses of 9÷10 t d.m. of sludge/ha will exclude potential cadmium accumulation in soil.

Opis:: W artykule przedstawiono metodykę oceny zanieczyszczenia powietrza atmosferycznego wskutek działalności kompostowni osadów ściekowych. Oceny dokonano poprzez identyfikację źródeł emisji, wskazanie rodzajów i ilości zanieczyszczeń z poszczególnych źródeł oraz określenie maksymalnych stężeń zanieczyszczeń i częstości ich przekraczania w stosunku do wartości odniesienia lub dopuszczalnych poziomów substancji w środowisku. Temat zrealizowano na przykładzie projektowanej kompostowni osadów ściekowych w miejscowości Zbarzewo (woj. wielkopolskie). Przeprowadzona analiza wykazała brak ponadnormatywnych stężeń zanieczyszczeń powietrza w rejonie planowanego przedsięwzięcia.
A method of assessment of ambient air pollution due to sewage sludge composting activities. The assessment was done by identifying the sources of emissions, an indication of the types and amounts of pollutants from various sources and to determine the maximum concentrations of pollutants, and the frequency of crossing in relation to the reference value or maximum levels of substances in the environment. Subject implemented on the example of the proposed composting of sewage sludge in Zbarzewo (province Greater). The analysis showed no abnormal concentrations of pollutants in the area of the proposed project.
