Opis:
Grasses' pollen produces allergens, which are the main cause of pollinosis in Poland and in many countries of Europe. In Poland the beginning of season falls in different days of May. Pollen monitoring was carried out in Lublin by volumetric method in years 2001-2004 by means of Lanzoni VPPS 2000 trap. Start of grass pollen season was marked by methods 98 % and Ʃ 75 as well as by the Clot's method. Differences between them ranged from 1 to 7 days. The most approximate deadlines of beginning of pollen season were qualified according to methods 98 % and the Clot's one, except year 2002. It was defined the pollen season in Lublin begins between 5. and 21. of May. In that study impact of meteorological factors on the beginning dates of pollen seasons was estimated. It was stated statistically positive, essential correlation among the beginning of season and the daily mean, the minimum and maximum air temperature.
Pyłek traw wytwarza alergeny, które są główną przyczyną pyłkowicy w Polsce i w wielu krajach Europy. W Polsce początek sezonu przypada w różnych dniach maja. Monitoring pyłkowy prowadzono w Lublinie w latach 2001-2004. Zastosowano metodę wolumetryczną z wykorzystaniem aparatu Lanzoni VPPS 2000. Początek sezonu pyłkowego traw wyznaczono metodą 98 % i Z 75 oraz metodą Clot'a. Różnice między metodami wynosiły 1 - 7 dni. Najbardziej zbliżone terminy początku sezonu pyłkowego określono metodami 98% i wg Cloť a, z wyjątkiem roku 2002. Ustalono, że sezon pyłkowy rozpoczyna się w Lublinie między 5. a 21. maja. W pracy oceniano wpływ czynników meteorologicznych na terminy rozpoczęcia sezonów pyłkowych. Stwierdzono dodatnią istotną statystycznie korelację pomiędzy początkiem sezonu a dobową średnią, minimalną i maksymalną temperaturą powietrza.

This paper presents data on daily precipitation totals from six meteorological stations and the climatic water balance for the stations located throughout Poland in 2011-2015. The following sequences of days without precipitation were distinguished: from 11 to 15 days, from 16 to 20 days, and of more than 20 days. The number of precipitation-free sequences during the growing season in 2011-2015 was highly variable. Over the studied period, there were from 1.0 rainless sequence in Wtelno to 2.4 such sequences in Gołębiów per one growing season. The most frequently occurring were sequences of 11-15 days, while those of 16-20 days were less frequent. In the years under analysis, all of the different sequences occurred most frequently in July, and the least frequently in April. The highest numbers of sequences without precipitation were recorded in the south-east of Poland (Zakalniki, Gołębiów).

Opis:
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.

Opis:
In this article distribution of monthly phosphorus loads flowing out of two agricultural catchments which are located in different physiographic conditions of Lower Silesia was analysed. Loads of phosphorus runoff from the catchment located in the piedmont part of Lower Silesia in each month rarely exceed 0.10 kg P · ha-1. The size of annual load is determined by loads obtained in two months of early spring. Much lower loads obtained for lowland catchment, located near Wroclaw. Values calculated for each month rarely exceed the value of 0.01 kg P · ha-1. Culmination of loads bringing away is a bit more extended in a time compared to the catchment located on Sudety Mts. Foreland. Much higher loads are observed during the period from January to April – this period has a major impact on the size of phosphorus load that flows out from this catchment during whole hydrological year. The obtained results clearly indicate that the threat of watercourses and water reservoirs supply in phosphorus compounds from agricultural land is periodic and it is particularly high during early spring. Phosphorus load flowing out from the analyzed catchments is very diverse. From facility located on Sudety Foothill in hydrological year, during research period, flowed away average 0.81 kg P · ha-1. Significantly lower values were obtained for second facility and it was average 0.15 kg P ha-1 during a year. The size of load discharged during a year is largely determined by amount of phosphorus load flowing out during winter half of the year (from XI to IV). In case of foothill catchment in this period flowed out average 0.56 kg P · ha-1, which presents 69% of annual load and in lowland catchment this percentage was even slightly higher and was 73%.

Opis:
The quality of Amba River in Nasarawa State in the North Central Nigeria was investigated for a period of one year covering dry and rainy season. Water samples were collected from four different locations (Gandu, Wadatan-Waje, Kofan-Kaura and Unguwan-Galadima) along the river course and analyzed for Bacteriological parameter, using standard methods. The results indicated seasonal variation in coliform population with higher values at Wadatan-waje and Unguwan-galadima during rainy season. The values obtained for coliform on the average for the two seasons were beyond the maximum acceptable standard set by the World Health Organization (WHO, 2004) for drinking water. Thus, settlers along the River should be enlightened on the danger of consuming untreated water from the River. Also, measures at regulating the pollution of the River should be taken for a healthy and vibrant community.

Opis:
This study determines the approximate duration of the thermal seasons in Warsaw, and investigates their long-term variability. The measurement data come from the Ursynów meteorological station at the Warsaw University of Life Sciences (WULS) (λE 21°02’52’’, φN 52°09’38’’, 102.5 m a.s.l.), situated in the south of Warsaw, and comprise mean diurnal air temperatures for the years 1961-2013. In order to identify thermal seasons, the method of five-day rolling averages was applied, which revealed a substantial year-by-year variability. The achieved results were close to those found by other methods for stations situated within the same climatic region. Over the analysed period, winters and springs have become shorter, whereas the other two seasons have become longer. Nevertheless, the positive trend was only statistically significant for thermal summers. The increasing length of the thermal summer in Warsaw Ursynów may be due to the influence of urban heat islands in built-up areas.

Opis:
Birth month in humans is associated with certain biological variables such as reproduc-tive success, health and mortality rate. At the same time, physical attractiveness is regarded as one of the reliable markers of human health and genetic quality, which suggests that female attractiveness may vary according to their season of birth. To test this hypothe-sis, ratings of females’ photographs from a popular Polish social networking website were analyzed. The sample included 5294 females aged 21-23 years. Results demonstrated that females born in spring (May) were rated as being significantly more attractive than those born in autumn (September and November).

Opis:
Species distribution models are used to predict ideal grounds, species range, and spatial shifts in an ecology over a span of time. With an aim to use Maximum entropy model (MaxEnt), presence records and pseudo-absence points are used to predict the Tachypleus gigas spawning activity for 2030 and 2050 in northeast India. The bearings of sixty T. gigas spawning grounds identified in 2018 were inserted into ArcGIS v.10.1. Meanwhile, 19 environment variables were inserted into MaxEnt v. 3.3.3, before the model performance was tested using receiver operational characteristics and area under curve (AUC). With an AUC of 0.978,85% was achieved for isothermality (bio3) and 74% for temperature (x̄= average) of the wettest quarter (bio8), all of which were inserted into ArcGIS to produce spatial maps. Although we learnt that T. gigas are still spawning in Odisha in 2030 and 2050, their distribution range is predicted to shrink due to the coastal morphology change. The climate conditions in Odisha revolve with the monsoon, summer and winter seasons from which, temperature variations do not only influence the annual absence/presence of spawning adults but also, the survival of juveniles in natal beaches. The use of MaxEnt offers novelty to predict population sustainability of arthropods characterized by oviparous spawning (horseshoe crabs, turtles, terrapins and crocodiles) through which, the government of India can take advantage of the present data to initiate the coastal rehabilitation measures to preserve their spawning grounds.

Opis:
Currently, the soot load from solid fuel combustion is not measured or counted, because it is included as part of particulate matter emitted from combustion sources. However, recent reports indicate that after carbon dioxide, soot is the most important contributor to current climate change. Therefore, an attempt was made to assess the soot load that is emitted during the winter season from individual heat sources where hard coal was burned or co-fired. Soot emission analysis and assessment were carried out in the selected settlement unit. Soot was collected monthly throughout the heating period at the chimney flue outlet, and analyzed for the PAH content. From these results and the information obtained from the users of individual heat sources, the soot load emitted from the installation in question during the entire heating period and the load of the sum of 16 PAHs and benzo(a)pyrene also during the entire heating period were calculated. It was found that the PAH content in soot largely depends on the type of boiler, the form of hard coal and wood addition burned, and the age of the boiler. The soot load, on the other hand, depends on the amount of hard coal burned, the type of boiler, how the combustion process is carried out, etc.
