Czy Nysius huttoni (Hemiptera: Heteroptera: Lygaeidae), gatunek obcy dla Europy, może mieć w Polsce sprzyjające warunki do bytowania?
2020
Nysius huttoni, the species endemic to New Zealand, is regarded as a pest which feeding can seriously reduce crop establishment in forage brassicas. It was discovered for the first time in Europe in 2002 (the Netherlands) and has spread in several European countries (Belgium, France, United Kingdom, Germany). Although detailed data on the natural spread of N. huttoni is lacking, it can theoretically be transported over long distances with infested plants, and is often found on apple and kiwi fruit packages exported from New Zealand. The species was hitherto not reported from Poland, therefore its potential geographic distribution was modelled using maximum entropy (Max-Ent) in order to pred…
Historia Domu Rekolekcyjnego Konferencji Episkopatu Polski "Księżówka" w Zakopanem w latach 1910-1945
2016
W artykule została przedstawiona droga do zrealizowania, podjętego w 1891 r., przez Stowarzyszenie Domu Zdrowia dla Kapłanów w Zakopanem założenia, budowy domu wspólnoty, z uwzględnieniem bazy zakładu leczniczego. Obiekt przyjmował różną formułę: od domu dla księży w celach zdrowotnych, turystycznych po współczesne funkcje rekolekcyjno-szkoleniowe; od przeznaczenia dla osób wyłącznie duchownych, po szeroką ofertę korzystania z domu przez osoby świeckie. Tekst wprowadza w atmosferę panującą w „Księżówce” w czasach zaboru austriackiego, w II Rzeczypospolitej oraz w okresie okupacji hitlerowskiej.
Niedoszła wystawa prac Feliksa Topolskiego w Nuzeum Narodowym w 1956 roku
2014
In 1956 in the National Museum in Warsaw there was to be and exhibition of the works of Feliks Topolski, a world-famous painter and illustrator living in Great Britain. The People’s Republic of Poland embassy in London contacted Topolski. Yet Topolski came to Poland only in 1961.
From the poster boy of Europeanization to the sick man of Europe: thirty years (1990–2019) of Poland’s European policy
2021
The Eurosceptic turnabout which has taken place in the CEE constitutes one of the most significant factors weakening the cohesion of the EU. In this group, Poland is the key element in view of its size and the status of the ‘poster boy’ of Europeanization acquired in the previous years. This paper analyses the major trends in the European policy of the Polish governments in the long-term period of 1990–2018 on the basis of standardized data (addresses by the Polish ministers of foreign affairs) and a quantitative analysis. These data also shed light on the essence of changes taking place in Poland’s EU policy. What appeared to be important was both the change in the country’s status after j…
Reglamentowana odwilż. Obóz „zamkowy” na emigracji wobec wydarzeń w Polsce i bloku komunistycznym w 1956 roku
2016
The article presents the position of “the Castle” on emigration (the President, government and the Council of the Republic of Poland) towards the events in Poland and the Eastern Bloc in 1956. The politicians and publicists of “the Castle”, observing some changes in the country, did not expect that they would lead to basic changes. The opinion prevailed that Poland was not an independent state and that the Soviet occupation still persisted. Propagating maximum demands (independence, restoration of the pre-war border in the east), they did not have much hope in an evolutionary course of changes. They opted for a deposition, and not a liberalisation of the communist system in Poland and the r…
The Moss Biomonitoring Method and Neutron Activation Analysis in Assessing Pollution by Trace Elements in Selected Polish National Parks
2020
The concentrations of trace elements in feather moss Pleurozium schreberi (Brid.) Mitt. were used to indicate the relative levels of air pollution by trace elements in Polish national parks. Pleurozium schreberi was collected from nine national parks. The highest concentrations were recorded in the moss samples from the southern and most industrialised part of the country; the lowest from northern and north-eastern Poland. A comparison of data obtained from Polish national parks in the 1970s and 1990s showed a significant decrease in the concentrations of heavy metals. In the linear covariability estimation, the t quantile approach was used for multi-element comparison. A number of positive…
Effect of deicing salts on urban soils and health status of roadside trees in the Opole region.
2004
This article reports on a study whose aim was to evaluate the impact of snow removal salts on urban soil properties and the health of roadside trees. The evaluation was done by chemical analyses of soil samples and plant matter combined with toxicity testing, performed with a Protoxkit F, a protozoan microbiotest. Samples were collected at 45 locations on three main roads in the town of Opole (Poland). The roads differed in the snow removal technology and amount of chemical substances (mostly NaCI) used on them during the winter. The study showed that when soil was exposed to a high level of NaCI, it tended to be more alkaline and also exhibited increased content of Na + and Cl - . The toxi…
Data quality oriented procedure, for detailed mapping of heavy metals in urban topsoil as an approach to human health risk assessment
2021
Abstract Urban soils' health is important to the community because of the soils' potential use for recreational activities. A data quality-oriented approach to sampling design is proposed for performing soil representative surveys that gives support to defensible and statistically-based decisions. Krowoderski park in Cracow (Poland) was selected as a study case to investigate heavy metals (HMs) accumulation and to assess human risk exposure according to simulated scenarios. Statistical power was computed for optimizing the number of samples to compare HMs concentration against legal upper tolerance levels (LUTL). The samples' location was iteratively designed as random spatial distribution …
The influence of preparation methodology on the concentrations of heavy metals in Pleurozium schreberi moss samples prior to use in active biomonitor…
2020
AbstractActive biomonitoring is used to assess environmental pollution of elements such as heavy metals by indicator species such as mosses. They are used, among others, in urbanized areas where no indicator species are found. In such study areas, mosses collected from sites considered to be ecologically clean shall be exposed. In this context, it is very important to prepare the mosses properly before the exposure, so that the information received about the condition of the environment is reliable. In 2018, studies were conducted in the forested areas of southern Poland—in Opolskie Province. Pleurozium schreberi mosses were used in these studies. Atomic absorption spectrometry with flame a…
Algae utilization in assessment of the large Turawa Lake (Poland) pollution with heavy metals.
2011
This investigation was undertaken to determine the applicability of algae for the assessment of contamination level of water reservoirs with heavy metals. The alga Spirogyra sp. collected in the littoral zone of the Large Turawa Lake (artificial lake in Southern Poland) was used for the study. The concentrations of heavy metals accumulated in the alga inhabiting a flow-through water basin of the Large Turawa Lake were found to correlate with sources of these metals, such as benthic sediments and contaminated watercourses. The highest concentrations of metals were found in alga samples collected at the outlet of the lake: c (Mn) = 12330 mg/kg dry mass, c (Fe) = 15059 mg/kg d.m., c (Cu) = 47.…
