The increasing threat of terrorist attacks in Europe and social demands for governmental actions towards facilitating an information exchange between the national authorities responsible for public security, lead to the spectacular shift towards collection of passengers’ data. Initially, the idea had concerned mainly aviation passengers’ data and was limited to international flights only. But soon it was extended in order to include the Passenger Name Records (PNR) from domestic transport. Recently, we can see tensions to expand the PNR collection scheme to other means of transport including maritime routes. The paper studies the most developed system created in Belgium and assesses its influence on possible all-European solutions. When presenting the main problems connected with profiling the passengers and data sharing between institutions, it discusses a lack of precise privacy impact assessment and the need for necessity and proportionality studies to be carried out both at the level of Member States and in the EU discussion on the implementation of the so called PNR Directive and on the new requirements for the digital registration of passengers and crew sailing on board European passenger ships included in 2017 amendments to Directive 98/41/EC.
This article examines the process of opening datasets accumulated by public institutions, and its impact on the rise of new types of journalism, in particular data journalism.
The main objective of the study was to evaluate if macrophytes structure and trophic status of dam reservoir Kraśnik on a small lowland river Wyżnica are determined by phosphorous loadings. Studies were conducted seasonally in May, July and October during the years 2008-2009. Samples were taken at four sites: Site 1 - inflow of the Wyżnica River to pre-dam, Site 2 − pre-dam, Site 3 − dam reservoir and Site 4 - outflow of the Wyżnica River from dam reservoir. Physical and chemical parameters (temperature, Secchi disc depth, dissolved oxygen, pH, conductivity, total suspension, chlorophyll-a, TP and P-PO4) were measured in water samples. Together with water parameters there were estimated biomass of phytoplankton and species composition and biomass of emergent, floating-leaved and submerged macrophytes. Concentrations of TP, chlorophyll-a and Secchi disc depth were used to calculate trophic state index of Carlsson for dam reservoir and its pre-dam. Based on mean water current, mean residence time of water in dam reservoir and concentrations of TP and P-PO4 loadings (g m-2) flowing into dam reservoir with the Wyżnica River were calculated. The results showed visible negative effect of phosphorous loadings on both macrophytes composition and trophic state of the reservoir. The marked changes concerned soft vegetation. High P loadings (7.74 g m-2 of TP and 6.03 g m-2 P-PO4) during the spring of 2008 caused the disappearance of characeans meadows. In 2009, the presence of rigid hornwort (Ceratophyllum demersum L.), the species typical for eutrophic lakes was noted. This unrooted submerged plant uptakes dissolved orthophosphates directly from the water column.
Values of Carlsson index (51.4 ≤ TSI ≤ 68.2) indicate the eutrophic state of dam reservoir Kraśnik. During summer season in dam reservoir there were observed algal blooms (biomass of phytoplankton exceed 10 mg WW dm-3) and low water transparency (Secchi disc depth ranged from 0.4 to 0.65 m). During the two-year studies in dam reservoir Kraśnik a high reduction of P loadings, mostly dissolved orthophosphates was observed. Dependently on season, reduction of P-PO4 loadings ranged from 52% (July 2008) up to 91% (May 2009). The reduction of TP was lower and reached values from 15% (May 2008) to 48% (July 2009).
As of the spring of 2017, the HAŁDY Database is available on the Polish Geological Institute – NRI website. The geodatabase contains information and data on waste mineral raw materials collected on old heaps, industrial waste stock-piles and in post-mining settlers, from the Polish part of the Sudety Mountains. The article presents the types of data and information contained in the geodatabase and the methodology for their collection. As a result of four-year research works, field reconnaissance, archives and geological basic research, 445 objects of former mining and mineral processing were inventoried. There are 403 mine heaps, 16 industrial settlers, 23 stock-piles and 3 external dumps. These are mainly objects after coal mining and metal ores, including post-uranium. The greatest opportunities for the economic use of waste are associated with coal sludge accumulated in settlers of the liquidated Lower Silesian Coal Basin. The material from stone heaps after polymetallic, iron and fluorite ore mining is also easy to use. The issue of the economic use of post-flotation copper ore waste or the recovery of metals (including gold) from dumps of arsenic mining remains open. The limitation here is the efficiency of metal recovery technologies and environmental restrictions. Some of the objects are located in protected areas, which excludes the possibility of waste management. Some stock-piles and heaps should be carefully reclaimed and covered by environmental monitoring, due to their harmful impact on environmental components.
W artykule opisano spory wokół sposobów zbierania danych na temat smogu w Polsce. Ramą teoretyczną analizy są studia nad nauką i technologią, a w szczególności badania nad rolą infrastruktur, standardów i danych. W części opisowej przedstawiono rolę infrastruktury pomiarowej w kształtowaniu relacji pomiędzy różnymi podmiotami zajmujący się pomiarem jakości powietrza, a następnie zanalizowano dwa wymiary konfliktu. Pierwszy z nich dotyczy kwestii metodologicznych i związany jest z rzetelnością pomiaru. Drugi natomiast – ontologii smogu, to znaczy odmiennego ujmowania problemu zanieczyszczenia przez ekspertów i obywateli, co ma przełożenie na praktyki społeczne.
The study presents the results of the research into different phosphorus forms in the bottom sediments of anthropogenic limnic ecosystems i.e. the reservoirs of Pławniowice, Rybnik and Goczałkowice (SP). The bottom sediments of dam reservoirs were investigated by chemical extraction procedure for phosphorus forms. The lowest value of the mean AAP form percentage in the Pławniowice bottom sediments reflected the effect of reclamation with the hypolimnetic removal that had been conducted in the reservoir since 2003. The highest percentage of the RDP form (2%) was found in the Goczałkowice bottom sediments. The order of the specific speciation forms in the bottom sediments of the examined reservoirs was:
Rybnik: AAP > EP > WDP > RDP; 4,630> 3,740 > 117 > 65 > 3.5 mgP/kg
Pławniowice: AAP > EP > WDP > RDP; 916 > 783 > 107 > 15 > 1.4 mgP/kg
Goczałkowice: AAP > WDP > EP > RDP; 686 > 628 > 51 > 7 > 0.14 mgP/kg
The mutual correlations between the phosphorus speciation forms (AAP : EP : WDP : RDP) were as follows:
Rybnik: 1,323 : 1,068 : 33 : 18 : 1;
Pławniowice: 654 : 559 : 76 : 11 : 1;
Goczałkowice: 4,900 : 4,485 : 364 : 50 : 1.
The comparison of the mean concentration values for specific phosphorus forms in the bottom sediments of the three investigated reservoirs demonstrated that the Rybnik sediments had the highest contents of phosphorus. The contents in Pławniowice and Goczałkowice were 5-7 times lower
