“Historical changes in air pollution in the tri-border region of Poland, Czech Republic and Germany”. Worobiec A, Zwozdziak A, Sówka I, Zwozdziak J, Stefaniak EA, Buczyńska A, Krata A, van Meel K, Van Grieken R, Górka M, Jedrysek M-O, Environment protection engineering 34, 81 (2008)
Abstract: In this study, we show the trends in the concentration Of SO2 and particulate matter (PM) in two health resorts, located in the tri-border region of Poland, Germany and Czech Republic. We analyze the annual time series and the seasonal variability of PM concentration for the months of July and February over the period of 1996-2007. Additionally, in July 2006, we measured the mean 24-hour concentration of PM and the content of heavy metals (by EDXRF analysis). We prove that nowadays air pollution in this region has diminished to a large extent as compared to the 90s of the last century. In Cieplice, the local influence is still evident; while Czerniawa is exposed to a periodical advection of polluted air from regional sources.

“Ion exchange-ultrafiltration integrated process as a useful method in removing natural organic matter from water”. Kabsch-Korbutowicz M, Kozak A, Krupińska B, Environment protection engineering 34, 79 (2008)
Abstract: The experiments conducted are focused on natural organic substances, removal from water in ion-exchange process, ultrafiltration process and ion exchange-ultrafiltration integrated process. The water from the Odra River and model solution were investigated. In treatment processes, various doses of 5 anion-exchange resins as well as polyethersulphone membranes with different cut-offs were used. The efficiency of process was determined by measuring a decrease both in the colour intensity and the UV 254 nm absorbance. The results show that separation efficiency in integrated process depends on resin dose added to water before ultrafiltration and on the membrane cut-off as well. Among the resins tested the most efficient was MIEX (R) resin. The ion-exchange process carried out prior to the ultrafiltration increased, especially for high cut-off membranes, NOM retention and resulted in the decrease of membrane fouling intensity.
