IMPACT OF MINE WATER FROM THE UPPER SILESIAN COAL BASIN AREAS ON CHANGE QUALITY OF WATER IN OLZA RIVER IN YEARS 2000–2007
Andrzej Harat, Arnošt Grmela
Summary
In the following article, the assessment of mine water from USCB area on the change of water quality in Olza river in years 2000-2007 was presented. The impact in this field is confirmed by surface water tests in Poland and Czech Republic. Presented activity is also a great example of long-term and fruitful cooperation between neighboring countries which comes from international agreement in terms of environmental monitoring.

IMMISSION OF SO2, NO2 AND O3 TO INTEGRATED MONITORING BASE STATION “POŻARY” ON GROUND OF AUTOMATIC MEASUREMENTS PROVIDED BY VOIVODSHIP INSPECTORATE FOR ENVIRONMENTAL PROTECTION
IN WARSAW IN 2004-2007
Anna Andrzejewska, Adam Olszewski
Summary
Automatic measurements of air pollution are provided on The Integrated Monitoring Base Station “Pożary” in Granica village since 2004. Concentration of SO2, NO2, O3 and meteorological parameters are measured hourly. Gases concentration were analized according to their dependance on air temperature, wind speed and direction and time of the day. The grow of SO2 and NO2 with decrease of temperature is evident. Higher concentrations of SO2 and NO2 during low wind speed indicate comparatively close emmission sources.

COMPARISON OF EVAPORATION ESTIMATION RESULTS FOR LĘKUK LAKE OBTAINED BY CALCULATED AND MEASUREMENT METHODS
Zdzisław Prządka
Summary
The lake water balance estimation largely depends on the water-surface evaporation estimation, which is defining by basing on mathematical formulas with empirical coefficients or basing on direct evaporation measurement.
In this article evaporation estimations obtained by two methods: calculated and measurement is presented. The first method is using (from 2003) in the Institute Environmental Protection in Warsaw and is based on Peneman formula. The second method was entered in 2008 and is based on Wild type’s evaporator installed at the meteorological garden of Puszcza Borecka Station. Using apparatus is a electronic weight (type EWA-992), surrounded by meteorological cage. The main advantage of this method is an automation of evaporation estimations. In the measurement method it was needed apply corrective coefficient. This coefficient was determined by comparison the evaporator EWA-992 and the standard evaporator GGI 3000, which was placed on a raft anchored on Sławskie Lake near the Station of Institute of Meteorology and Water Management in Radzyń.
The comparison evaporation estimation methods shows that calculated method based on Peneman formula lowers months sums of evaporation indifferently about 20 per cent beside measurement method. This faults, which sometimes may be higher, have an importing contamination on the estimation of lake water balance. As the estimation analysis presented, monthly proportional differences of the lake retention defined by mathematical formula and directly evaporation mensurations are from -20% to +120% .
Analysis of presented data shows that application Wild’s type evaporator needs a apparatus calibration with a cover in the area conditions where there are realizing surveys, also during different seasons.
Using uncalibrated apparatus give rise to the faults of evaporation estimation as like the faults appearing during using the Penman formula.

EFFICIENCY AND SELECTIVITY OF REAGENTS USED TO CHEMICAL FRACTIONATION OF HEAVY METALS IN ENVIRONMENTAL SOLID SAMPLE
Ryszard Świetlik, Marzena Trojanowska
Summary
Total concentration of metals in environmental samples does not provide suitable information about mobility and bioavailability of potentially toxic elements. It is now widely recognized that the toxicity and the mobility of metals depend strongly on their specific chemical forms and physical phases. Single and sequential extraction methods have been widely applied to characterize the chemical forms of metals in solid samples. Sequential selective extraction techniques are commonly used to chemical fractionation the solid-phase forms of metals in environmental samples. Many sequential extraction schemes have been developed for different solid samples (sediments, soils, slugdes). Despite numerous criticisms, extraction procedures remain very useful in environmental studies and are considered an essential tool in establishing element fractionation in solid phase. This article reviews the most commonly reagents used in the various procedures. From this review, it appears that all reagents used in various schemes have advantages and disadvantages. The choice of procedure must be related to a definite objective, taking into account nature of the sample and selectivity of the reagents used in the procedure.
