An analysis of hazel pollen seasons in Sosnowiec was presented on the basis of data from the years 1997–2007. The research was conducted by means of the volumetric method using a Burkard-type spore trap. The duration of pollen seasons was determined by means of the 98% method. The research demonstrated statistically significant correlations between the average, maximum and minimum temperature, relative humidity as well as the number of days with sub-zero temperature and the beginning of the hazel pollen season. It was demonstrated that the duration of the pollen season depended on air relative humidity, insolation and precipitation during the season and the annual sum depended on the weather conditions of the year preceding pollen production and also the weather conditions two years earlier. Significant correlations were also found between weather conditions and the daily concentration of pollen grains. The daily concentration decreased when relative humidity was high and increased with high insolation and air temperature.
This paper investigates pollen seasons for Corylus spp. and Alnus spp. for the years 1997-2007 in Sosnowiec, southern Poland. The research was conducted by means of the volumetric method using a Burkard-type spore trap. The duration of pollen seasons was determined by means of the 98% method. The aim of this study was to distinguish the types of the course of hazel and alder pollen seasons using cluster analysis, including non-hierarchical clustering of multi-feature objects – k-means clustering. The pollen seasons were divided into five types because of considerable variations from one year to another. For both taxons one dominant type was found, which was characterized by a very long period of compact pollen release with low values of the pollen count and by the occurrence of several maximums divided by periods of a lower pollen count. This work contains only a preliminary analysis on the types of pollen seasons because of relatively short data set. Future research on a larger series of measurements should be proved.
The investigation of Ambrosia pollen counts in the air of Sosnowiec was carried out from 1998 to 2010 by means of the volumetric method. The pollen season which was determined by means of the 98% method started at the end of July and the beginning of August and lasted until the end of October. The highest Ambrosia pollen count was recorded in 1999 (222 grains x m-3) and the lowest in 2001 (18 grains x m-3). It was stated that the daily count of pollen grains depended on the wind direction and maximum air temperature. The strongest correlations were found with maximum temperature and with a wind direction from the south east. A high negative correlation coefficient was found between the frequency of inflows of air masses from the west and the annual total of pollen grains and the value of the maximum daily count. The closest sites of Ambrosia L. are at a distance of 25–40 kilometres from the sampling point. Significant correlations with the frequency of inflow of air masses can support the conclusion that Ambrosia pollen grains recorded in Sosnowiec were most probably carried not only from local sources but also, at least in part, from distant places.
The article presents the analysis results of the grass pollen seasons from 1997 to 2006 in Sosnowiec. The research was carried out by means of the volumetric method with the use of a Burkard device. The duration of the pollen seasons was determined by means of the 98% method. The influence of meteorological conditions on the starting date and duration of the grass pollen seasons has been estimated in the article. The beginning of the pollen seasons was recorded between 23 April and 23 May. It has been demonstrated that the average duration of the pollen season amounted to 138 days. The period of maximum concentrations was recorded in June and the first half of July. The highest daily concentration was found in 2000 (495 grains in m³) and the highest annual sums in 2002 and 2000. The daily concentration distribution curve has shown three peaks. The highest values were recorded from 7 am until 11 am, from 13 pm until 17 pm and from 19 pm until 21 pm. It has been found that there is a significant influence of weather conditions (temperature, precipitation and relative humidity) on the beginning and duration of the pollen seasons and the period of maximum concentrations.
During the field research in various phytocenoses of Sosnowiec city in year 2002, altogether 98 species of planthoppers and leafhoppers, which constitute 19% of Polish fauna were found. The new species for Upper Silesia are: Eurybregma negrolineata SCOTT, 1875, Arboridia erecta (RIBAUT, 1931), Arboridia velata (RlBAUT, 1952), Doratura impudica HORVÁTH, 1897, Mocydiopsis attenuata (GERMAR, 1821). Moreover two species: Backlutha calama-grostis OSSIANNILSSON, 1961, and Doliotettix lunulatus (ZETTERSTEDT, 1840) were confirmed as still present in Upper Silesian region.
W pracy ukazano możliwości zagospodarowania terenów pokopalnianych w dwóch polskich miastach średniej wielkości – Sosnowcu i Zielonej Górze. Teren w Sosnowcu obejmuje część dawnej Kopalni Węgla Kamiennego „Niwka”, natomiast w Zielonej Górze – dawnej cegielni „Krośnieńska” i kopalni węgla brunatnego, działających w ramach Consolidierte Grünberger Gruben. Współcześnie tereny te są nieużytkami, o silnie zdegradowanej powierzchni ziemi. Autorzy artykułu zaproponowali wobec nich zagospodarowanie parkowe, z pozostawieniem elementów ich przeszłości przemysłowej. Tym samym, poza rekreacją i wypoczynkiem, obszary te nabiorą cech ciekawych, unikatowych parków tematycznych nawiązujących do przemysłowej historii miast.
Badano narażenie na tlenek węgla wybranych grup ludności związane z zamieszkiwaniem terenów uprzemysłowionych i paleniem papierosów. Badaniami objęto grupy osób nienarażonych, narażonych środowiskowo i niepalących, nienarażonych środowiskowo palaczy papierosów. Wskaźnikiem narażenia było stężenie HbCO we krwi. Określono udział poszczególnych źródeł w narażeniu mieszanym na tlenek węgla.
