Opis:
This article is devoted to the study of water and sediment pollution in the channel of the Neva delta. Spectrophotometry was used to determine the concentration of pollutants in water. In the chemical analysis of the precipitate, atomic absorption spectroscopy and infrared spectroscopy were used. Analysis of the hydrochemical composition and sediment of the Smolenka River showed high concentrations of heavy metals and petroleum products. At the same time, the hydrochemical composition of the Smolenka River is highly unstable, but the concentration of oil products and lead in the sediments indicates the presence of local pollution sources. Based on our findings, we are guided by the restoration of the aquatic environment.

Opis:
Environmental monitoring is a very important part of all environmental risk assessment tasks aiming correct estimation of the ecological status of water, air, soil, and biota systems. However, special attention is rarely paid to the problem in the teaching programs for students of bachelor or master degree dedicated to environmental chemistry. The same holds true for secondary school programs for chemical education. It is the aim of the present communication to present in a simple and understandable way the major elements of the environmental monitoring as substantial consistent of the overall scheme of environmental risk assessment as presented to chemistry students and secondary school pupils.

Opis:
Radio frequency spectrum mapping allows determining the radio frequency signatures prevalent within an environment. We address the primary frequency bands used for cellular, wireless Local Area Network (LAN), Universal Mobile Telecommunications System (UMTS) and Ultra-wideband (UWB) communications. The purpose of the experiment presented in this paper is to map the detected radio frequencies within an environment and display the collated data on a graphical user interface. A program identifies the presence of the aforementioned radio frequency signatures and recognizes signal levels which exceed the exposure standards enforced by the Australian Communication and Media Authority. The results assist in the understanding of the ramifications of long-term exposure to radio frequency radiation associated with the continued proliferation of wireless devices.

Opis:
Electromagnetic fields radiation has raised concerns within several segments of the population in the past three decades. Many studies proved inconclusive, in part due to the scarcity of data. We propose the idea of a geographical model based radiation pollution database. We discuss networked sensing technology for detection and monitoring of electromagnetic fields. We elaborate on software engineering issues for the visualization in real time of electromagnetic field mappings and the dissemination of information through various means and levels of access. We propose the database be complimented by a data algorithmic software solution for the extraction of patterns.

Opis:
Recently, a lot of attention was paid to the improvement of methods which are used to air quality forecasting. Artificial neural networks can be applied to model these problems. Their advantage is that they can solve the problem in the conditions of incomplete information, without the knowledge of the analytical relationship between the input and output data. In this paper we applied artificial neural networks to predict the PM 10 concentrations as factors determining the occurrence of smog phenomena. To create these networks we used meteorological data and concentrations of PM 10. The data were recorded in 2014 and 2015 at three measuring stations operating in Krakow under the State Environmental Monitoring. The best results were obtained by three-layer perceptron with back-propagation algorithm. The neural networks received a good fit in all cases.

Opis:
The study aims to analyze the measurement data of PM10 particulate matter in the Krakow agglomeration. It develops a model of the backward trajectory of air masses to determine whether and to what extent natural phenomena, such as forest fires outside Poland, affect the level of air pollution. The article describes the process of pollutant dispersion in the Earth’s atmosphere and the principles of air monitoring in the Krakow agglomeration. The study uses 2022 measurement data from ten monitoring stations of the Chief Inspectorate of Environmental Protection in the Krakow agglomeration. Two periods of increased PM10 particulate matter were selected. On the basis of the HYSPLIT software, which uses backward air trajectories, the influx of transboundary pollution was simulated. Then, by analyzing the FIRMS fire information system, an attempt was made to document that the pollution sources considered were of natural origin and that human activity did not in any way determine the emissions and their magnitude.
Celem badań była analiza danych pomiarowych pyłów zawieszonych PM10 na terenie aglomeracji krakowskiej oraz wykonanie modelu trajektorii wstecznych mas powietrza w celu określenia, czy i w jakim stopniu zjawiska naturalne, takie jak pożary lasów poza granicami Polski, wpływają na stopień zanieczyszczenia powietrza. W artykule opisano proces dyspersji zanieczyszczeń w atmosferze ziemskiej oraz zasady monitoringu powietrza w aglomeracji krakowskiej. Do opracowania posłużono się danymi pomiarowymi z 2022 r. z dziesięciu stacji monitoringu Głównego Inspektoratu Ochrony Środowiska, znajdujących się na terenie aglomeracji krakowskiej, gdzie wytypowano dwa epizody zwiększonego stopnia zanieczyszczenia pyłami zawieszonymi PM10. Bazując na oprogramowaniu HYSPLIT, który wykorzystuje wsteczne trajektorie powietrza, przeprowadzono symulację napływu zanieczyszczeń transgranicznych. Następnie analizując system informacji o pożarach FIRMS, podjęto się próby udokumentowania, iż uwzględnione źródła zanieczyszczeń miały pochodzenie naturalne, a działalność człowieka w żaden sposób nie decydowała o emisji i jej wielkości.

Opis:
Oil pollution is a hazard both in terms of scale and toxicity. Oil and oil products cause poisoning, death of organisms and soil degradation. The natural self-purification of natural objects from pollution depends on the natural conditions of the region, the presence of moisture, heat and the activity of the vital activity of the soil biocenosis. Under the conditions of Siberia, where a low temperature regime is maintained for a long time, self-purification is a long process. As a result of the long industrial use of the Medvezhye oil and gas condensate field, the soils of this area have accumulated pollutants. Thus, it is required to assess the toxicity of the soil, as well as to provide the ways and methods to prevent its environmental pollution. One of the ways to restore disturbed landscapes is technical and biological reclamation, the features and results of which are considered in this study using the Medvezhye deposit sand pit as an example.

Opis:
The research is devoted to assessing the negative impact of the amber-succinite deposit in the Kaliningrad region as one of the sources of complex pollution of the Baltic Sea waters. The Baltic Sea is one of the most polluted water bodies in Europe today. There are many natural and anthropogenic factors that cause this ecological situation. Industry is one of the significant contributors to the pollution of the waters of the Baltic Sea. The industrial wastewater discharged into the Baltic Sea often does not comply with the state ecological standards. The wastewater disposal system modernization by creating a recycled water supply is one of the most effective ways to reduce the negative impact of industrial wastewater on the Baltic Sea ecosystem nowadays. This technological solution allows to significantly reduce or to completely prevent the discharge of wastewater into the Baltic Sea.
