Four commonly employed biotic indices based on macrofauna composition: BMWP (British Monitoring Working Party score system), ASPT (Average Score Per Taxon), DSFI (Danish Stream Fauna Index) and FBI (Family level Biotic Index) were used to assess environmental quality of six small slow-flowing lowland streams (Masurian Lakeland, North-eastern Poland). Their efficiencies in determining the level of degradation, assessed by the simoultaneous measuring of the main abiotic parameters of water, were tested. The search for relationships between both abundance and percentages of invertebrate taxa and values of the main abiotic parameters with multiple regression analysis resulted in determining an indicative value for certain taxa. Results of discriminant function analysis show, that environmental quality can be predicted accurately on the basis of macrofauna composition in 94-100% of the sites. However, none of tested indices classified the sites to particular classes of degradation with with sufficient accuracy. The relationships between the values of all tested indices and the values of Cumulative Index of Environmental Quality (CIEQ) based on abiotic parameters, expressed as coefficients of linear regression, were very low and ranged between 0.006 and 0.068. Therefore, a new regional, macrofauna-based biotic index, APODEMAC, is proposed as a better tool for environmental quality assessment. Values of APODEMAC are strongly dependent on values of CIEQ (R^2 = 0.641), and their seasonal variance is lower than that of other indices. Coefficient of linear regression between CIEQ values and APODEMAC was 9 to almost 100 times higher than for other tested biotic indices. The selection of indicator taxa used in APODEMAC procedure was based on comparisons between the taxa densities at sampling sites differing in terms of environmental quality and on the results of multiple regression and discriminant analysis. The importance of certain taxa of molluscs, leeches and dipterans in this procedure is much higher, while the importance of mayflies, stoneflies and caddisflies is much lower than in BMWP, ASPT, FBI and DSFI. The occurrence of the various larval insects in the studied environments seems to be limited rather by substrate type than by the chemical quality of stream water. Application of simple regional biotic indices like APODEMAC is suggested as an, in some cases, easier, cheaper and less time-consuming way of biological assessment compared to complicated and time-consuming implementation of the existing indices.

W artykule został poruszony problem biologicznej oceny działania oczyszczalni hydrofitowej. Obiekt badawczy stanowiła oczyszczalnia hydrofitowa położona w miejscowości Zwierki w gminie Zabłudów. W celu dokonania biologicznej oceny działania oczyszczalni wykonano badania wybranych wskaźników mikrobiologicznych. Wykonano posiewy próbek ścieków surowych, ścieków oczyszczonych oraz wód pobranych ze stawu odbierającego ścieki oczyszczone. W wyniku badań stwierdzono, iż złoże hydrofitowe w redukuje ilość drobnoustrojów obecnych w ściekach surowych. Natomiast w stawie odbierającym ścieki dochodzi do wtórnego zanieczyszczenia biologicznego.

This article discusses the problem of biological evaluation of the constructed wetlands. The constructed wetland located in Zwierki in the Zabłudów commune was a research facility. Biological evaluation of the constructed wetland was made by taking samples of raw sewage, treated sewage flowing out of the deposit and water from the receiving pond. Cultures were made on individual media to determine the presence or amount of the microorganisms concerned. After incubation, the approximate number of microorganisms on solid media was calculated. As a result of the research, it was found that the constructed wetland to some extent reduces the amount of microorganisms present in raw sewage. However, in the receiving pond, secondary biological pollution occurs.

Sediments are the major source of pollution in surface waters of the Pacific Northwest Region of the USA. The purpose of this study is to evaluate the relationship between SMI water quality scores at 76 sampling sites in eight watersheds and the observed soil erosion rates on adjacent landscapes. The water quality SMI scores in streams were obtained using stream macro invertebrates as an indicator of water quality, while soil erosion rates were determined by observation on adjoining landscapes during periods of maximum precipitation. Soil erosion rates of <2, 2–5, 5–15, 15–25 and >25 mt/ha/yr were observed at 9, 20, 45, 14 and 12% of the sampling sites, respectively. Landscapes with erosion rates of less than 5 mt/ha/yr generally resulted in good water quality in adjacent streams; however, when soil erosion rates on adjacent landscapes exceeded 5 mt/ha/yr SMI water quality scores were less than good 86% of the time. Strong signifi cant relationships were observed between SMI water quality rating and observed soil erosion rates. Consequently, land management or rehabilitation practices that reduce soil erosion rates to levels below 5 mt/ha/ /yr should improve stream water quality.

Rumowisko rzeczne stanowi główne źródło zanieczyszczenia wód powierzchniowych w zlewniach Pacyfiku w północno-zachodnim regionie USA. W pracy przedstawiono wyniki badań prowadzonych w ośmiu zlewniach w celu określenia zależności między indeksem jakości wody SMI w 76 przekrojach kontrolnych a wartościami wskaźnika erozji gleb na przyległych obszarach. Jako wskaźnik jakości wody do określenia wartość SMI wykorzystano badania makro bezkręgowców wodnych, natomiast wskaźnik erozji gleb określano na podstawie obserwacji terenu w okresach maksymalnych opadów deszczu. Uzyskano silną zależność między wartościami SMI a wartościami wskaźnika erozji gleb. Stwierdzono, że gdy wskaźnik erozji gleb przekraczał wartość 5 mt/ha/rok wówczas w 86% okresu obserwacji jakość wody była gorsza od dobrej, tj. słaba, zła lub bardzo zła. Zagospodarowanie terenu oraz działania w celu redukcji wartości wskaźnika erozji gleb poniżej 5 mt/ha/rok powinno poprawić jakość wody w ciekach.
