Research on the chemistry of atmospheric precipitation in the Hornsund region of Svalbard has been extended by analysis of the organic contents. In rainfall samples collected in September 2003, the organics were separated by solid phase extraction (SPE), eluted and analysed on gas chromatograph coupled to a mass selective detector (GC/MS). Rainfall pH was in the range 4.72-5.45, the low values suggesting possible pollution. Concentrations of inorganic ions, expressed as total dissolved salts (TDS), were 5.40-13.18 mg L-1. Non-sea-salt (nss) sulphates were in the range 5-11 µeq L-1. In all samples, long-chain alkanes with chain length up to C36, and their methyl derivatives were detected. Among aromatic compounds biphenyl, dibenzofuran and its methyl derivatives were found. Polycyclic aromatic hydrocarbons (PAHs) were represented by naphthalene, phenanthrene, fluorene, acenaphthene, fluoranthene and pyrene. There were no PAHs with higher numbers of rings. The synoptic meteorological conditions in September 2003 indicate that all organic and inorganic pollutants were of local origin.

Spływ powierzchniowy jest procesem złożonym, a czynniki od których zależy są zmienne zarówno w czasie, jak i przestrzeni. Badania laboratoryjne wykonano na modelu gruntowym o wymiarach: długość 136 cm, wysokość 120 cm, szerokość 15 cm. Eksperyment wykonano dla spadków 5%, 10% i 15%. Wnętrze modelu wypełnione zostało piaskiem gliniastym mocnym zagęszczanym warstwowo. Badania dowiodły, że w początkowej fazie opadu następuje zwiększenie wielkości spływu do momentu ustalenia się stanu równowagi pomiędzy intensywnością i energią opadu, a wielkością i energią spływu. Przeprowadzone badania wykazały, że wilgotność początkowa jest głównym czynnikiem wpływającym na proces kształtowania się spływu powierzchniowego.

Opracowanie oparto na wynikach pomiarów intercepcji opadów atmosferycznych, które wykonywano w latach 1995-1998 na polach ustalonych Obserwatorium Agrometeorologicznego w Felinie Akademii Rolniczej w Lublinie. Do pomiarów intercepcji użyto deszczomierzy w formie rynienek o powierzchni 200 cm2 i wymiarach 4x50 cm w kompletach po 10 przyrządów na poletku doświadczalnym. Pomiary prowadzono na poletkach z pszenicą ozimą, żytem ozimym, jęczmieniem jarym, bobikiem i koniczyną czerwoną. Łącznie zebrano 388 wyników pomiarów. Najwięcej wartości intercepcji stwierdzono w trzech przedziałach klasowych, w zakresie 20-50% - było tam 60,6% całości danych. Maksymalna liczebność - 80 wyników wystąpiła w przedziale klasowym 40-50%, co stanowi 20,6% próby. Średnia wartość intercepcji wahała się od 17,8% (jęczmień jary w 1995 r.) do 52,8% (bobik w 1996 r). Z obliczeń korelacji wynika, że najsilniejsze korelacje dodatnie wystąpiły pomiędzy sumami opadów na wolnej przestrzeni oraz ilością wody pod roślinami oraz pomiędzy opadami na wolnej przestrzeni oraz ilością wody pozostającej na roślinach. W kilku przypadkach stwierdzono ujemne korelacje pomiędzy wysokością opadów na wolnej przestrzeni i wartością intercepcji.

The present paper reports on the year-long study of atmospheric precipitation (rain and snow) composition, including nitrogen, phosphorus and mineral matter as conductivity, in ice-free area of western coast of Admiralty Bay (King George Island). The effects of the local Adelie penguin colony on nitrogen and phosphorus concentrations in atmospheric precipitation, as well as the role of wind on nitrogen and phosphorus enrichment of ice-free areas uncovered by a progressing deglaciation of the Ecology Glacier (ASPA 128) were examined. The effect of marine influence on the mineral matter level (as conductivity) in atmospheric precipitation was examined too. The determination of conductivity, nitrogen and phosphorus were assayed according to standard methods. Conductivity, nitrogen and phosphorus concentrations in atmospheric precipitation differed depending on sampling sites location, precipitation type (rain or snow), season (summer or winter), and also distance from a penguin rookery. The mean conductivity of rain and snow amounted to 189 μS cm⁻¹ and was higher in rain (up to 290 μS cm⁻¹) than in snow samples (87 μS cm⁻¹). Mean total nitrogen and total phosphorus concentrations in precipitation amounted to 0.208 mg Ndm⁻³ and 0.028 mg P dm⁻³, respectively. A higher conductivity was recorded in the precipitation transported by NNW winds (200 μS cm⁻¹), and lower in the precipitation transported by SSE winds (80 μS cm⁻¹). The seasonal variability of conductivity was characterized by a higher values during summer (320 μS cm⁻¹) and lower – during winter (90 μS cm⁻¹). The most nutrientrich samples were those collected in the centre of the penguin rookery, average values of TN and TP concentrations were 0.450 mg N dm⁻³ and 0.090 mg P dm⁻³, respectively. At the other sites concentrations of TN and TP were lower. Seasonal variabilty of nitrogen and phosphorus concentrations were usually characterized by minimal concentrations during winter and maximal – during spring or summer. The concentrations of nitrogen and phosphorus were characterized by a statistically significant negative relation along the distance from the penguin rookery and along the altitude of sampling sites. The influence of the penguin rookery on the higher concentrations of biogenic compounds caused the high concentrations of ammonium nitrogen (averaging about 0.250 mg N dm⁻³) during summer at all sampling sites, even at those, located farthest away (about 2200 m) from the penguin colony. The annual nitrogen and phosphorus loads deposited by atmospheric precipitation onto the ice-free area were estimated at about 0.752 kg N ha⁻¹ and 0.061 kg P ha⁻¹, respectively.

This paper reviews collectors for atmospheric precipitation (rain, fog, and run-off water). Collection systems of a different degree of automation (from simple designs to highly automated costly collectors) are presented. In many papers on collecting atmospheric precipitation neither sampling procedures nor locations of sampling sites are given, although this information is necessary for producing correct and comparable results of physical and chemical analyses.

Two-dimensional variance analysis of the results of determination of NO₃⁻, SO₄²⁻, F⁻, Al³⁺, Cl⁻, NH₄⁺,PO₄³⁻, Fe³⁺, Ca²⁺, K⁺ and Mg²⁺, and pH and electrolytic conductivity of precipitation water samples collected in the Tricity area showed that transregional transport of pollutants affects air quality in this region. Over the large area of the Tricity agglomeration fluctuations in analyte concentrations in precipitation water samples are not affected on a statistically significant level by localizing sampling sites, but the area affected by transport direction of air mass movement.

The analysis of rainfall from the period of 1971-2000 recorded in the Beskid Sądecki Mountains, in the phytoclimatic research station in Kopciowa near Krynica (φ = 49º 27'N and λ = 20º 58'E, located at the altitude of 720 m) indicated a strong rising tendency of rainfall in winter, spring and autumn. It was reflected in a clearly positive trend of the annual rainfall totals, despite the falling tendency of rainfall in the summer. On average, the annual rainfall totals were 1000 mm. During this 30-year period, the monthly totals of the summer months were characterised by the strongest variability, while the winter months' variability was the weakest. The highest rainfall totals were usually recorded in June and the lowest in February. The mean annual rainfall total increased during the thirty years by 208 mm. An increase in the amount of rainfall during spring and winter and a decrease in the summer indicates that the pluvial climate of the area under research has acquired oceanic features.

The performed observations indicate the possibility of making the prognosis of the hops harvest basing on the atmospheric conditions. Those data are not publicly presented in Poland. It's serious inconvenience in the hops production planning.
