Opis:: The paper goal is to develop a spatial analyses of the most critical environmental issues in the country and how the population concerns could be addressed with the use of spatial technologies. Population perception of environment management relies on its minimum levels. In the recent past, static, fixed scale, multi use, highly accurate, permanent, paper maps compiled over a short period of time was the norm, meanwhile today’s world uses a dynamic, single use, variable accuracy, variable scale, digital product made from data possibly retrieved from database derived from multiple sources. The opportunity to combine spatial technology associated with numerical data leading to a structured and genuine analyzes of the country issues turns to be an optimal strategy. We structure a set of digital maps encouraging decision-makers to rely their performance on spatial tools. Coastline pollution stands as a top priority. For the purpose of the analysis, the entire coastline was divided into sectors. Hence, further investigations could be addressed toward space-time relationship to cover the environmental evolution process, which may serve as an input for future predictions.

Opis:: In this article we presented the issues concerning the measurement of road noise, measurement results, and the discussion pertaining to the methods of limiting the excessive noise in the city of Lublin. Mobile systems, equipped with software which enables editing the measurement data, analysis and presentation of the data in the form of an acoustic map, are used to measure the noise level. Exemplary streets of the city are shown, where the road noise level has been significantly exceeded, and the effects of acoustic screens installation is presented. Moreover, the preventive and educational actions which are carried out in Lublin, meant to popularise alternative methods of transport, are discussed. It was concluded that an effective reduction of the traffic noise in the city can be achieved already at the stage of designing housing estates, along with the planning of access roads and noise barriers.

Opis:: The objective of this study was to determine the biodegradability of bioplastic materials – sponge cloths – available on the European market that are labeled as 100% biodegradable but not certified as compostable. The test was carried out in a controlled composting environment. The project length was 22 weeks. The emphasis was put on discovering whether the sponge cloths are biodegradable or not. Based on the results thereof it can be concluded that sponge cloths have not decomposed completely but their color has changed and that degradation and physical changes occurred. Samples A₁, and A₂ have not decomposed completely and exhibited very slow degradation rate. Sample B5 exhibited the highest degradation rate. Samples B₃, B₄ exhibited high degree of decomposition. The main conclusion from this study is that biodegradation of bioplastics materials strongly depends on both the environment in which they are placed and the chemical nature of the material.

Opis:: Specific conditions in urban areas favour large species richness, these are also places prone to the anthropogenic pressure. As a result, many studies on aquatic habitats in urban ecosystems have been carried out. The aim of this study was to investigate the diversity of diatom assemblages developing in artificial environment in relation to water chemical parameters. The study was performed on a small water outflow in south-eastern Poland, which started in the storm sewage. The water at the studied sites was characterized by alkaline pH and low content of nutrients. The values of other chemical parameters were highly variable, depending on the research season. A total of 113 taxa were identified in five research seasons; most of them prefer circumneutral and fertile habitats, with a high content of biogens and are tolerant to water pollutions. Aerophytic and terrestrial taxa were observed in the analyzed materials in high diversity.

Opis:: The abundance of microplastics (MP) in the aquatic environment is increasingly disturbing for maritime countries, especially Indonesia, because it has the potential to threaten the health and sustainability of aquatic ecosystems. This review summarized and discussed the distribution of MP abundance in Indonesian aquatic ecosystems which concluded that rivers, bays and estuaries, beaches, seas, and even fish and shellfish have been contaminated. The highest contamination of MP was found in the waters of Jakarta, West Java, and East Java, which are densely populated areas. The potential threat of exposure and accumulation of MP to human health was also discussed. However, differences in the methods and units of measurement for MP as well as limited information regarding the interaction of MP with human organ functions are weaknesses in this review. The future research on the relationship between food and feeding habits of the community around contaminated waters with the accumulation of MP in the human body is needed to identify the prevention and treatment strategies.

Opis:: We have obtained eight degradable/biodegradable materials based on starch (certified compostable), sample 4–7, HDPE mixed with totally degradable plastic additive (TDPA), sample 2 and polyethylene with the addition of pro-oxidant additive (d2w), sample 1. Composition of sample 3 has not been reported. The materials have been tested as to the rate and character of their degradability/biodegradability in controlled composting conditions. Experiment explored also the effect of degradation/biodegradation of plastic bags on compost quality. The material of the original samples was subjected to assessment using the Nicolet 6700 FT-IR spectrometer, the outcome thereof was obtaining infrared spectra of the samples. For further specification the original samples were tested using the thermogravimetrical analysis. The texture of the foils at different stages of degradation is presented in the Scanning Electron Microscope (SEM) photographs. Plastic bags certified as compostable have degraded in laboratory conditions and their degradation had no impact on the quality and features of compost. Selected samples (4, 6) showed significant erosion on surface when subjected to the SEM analysis. Samples labeled (by their producers) as 100% degradable (samples 1, 2, 3) did not show any visual signs of degradation and the process of degradation had no impact on the quality and features of compost. Only one of the samples (sample 1) showed certain erosion of surface when submitted for the SEM analysis.

Opis:: Omówiono źródła fosforu wnoszonego do środowiska w Polsce na tle łańcucha pokarmowego człowieka, który obejmuje gleby uprawne, płody rolne, żywność i końcowym etap łańcucha - odpady bytowe. Największe zagrożenie dla środowiska stwarza fosfor pozostawiany w glebach uprawnych, jego obfitość w osadach ściekowych oraz zawartość w środkach czystości. Gleby uprawne mają ograniczoną pojemność wobec fosforu, a ilości wnoszone z nawozami są systematycznie większe od wynoszonych z plonem. W ściekach bytowych zawartość fosforu do azotu jest 4 razy większa niż w nawozach naturalnych, a w doradztwie nawozowym osady nie są liczone jako nawóz. Największym jednak zagrożeniem jest możliwość stosowania dużej masy osadów ściekowych w celu zmniejszania podatności na erozję gleb. Wydaje się, że dodawanie fosforanów do żywności, w ilościach przekraczających często ich naturalną zawartość, nie budzi większego niepokoju wśród dietetyków. Rocznie do środowiska w Polsce dodaje się około 170 tysięcy ton fosforu, z którego 160 tysięcy ton w nim trwale pozostaje.
The sources of phosphorus input in to the Polish environment on the basis of human food chain were presented. This chain is following: arable soils, cops, food and communal waste. About 95% of phosphorus quarried from phosphate rocks is destined to human food chain, as fertilizers and as fodder and food additives. The end point of food chain are communal wastes. The greatest risk to the environment is made by the phosphorus left in the arable soils, its abundance sewage sludge and good solubility of its compounds in cleaning agents. Soils have limited capacity to bound phosphorus and its input with fertilizer is steadily greater than the output with crops. The ratio of phosphorus to nitrogen content in sewage sludge is about 4 times higher than in manure, nevertheless that is not considered in the Polish fertilizer recommendation system. Though, the highest risk is created in the using huge amounts of sewage sludge on purpose to lessen the capacity of soil to erosion. It seems, that the dietetics are not much afraid with the common approach to increase the phosphorus content in human food to the level higher than its natural content. About 170 thousand tones of phosphorus (P) is added into the Polish environment annually, from which 160 thousand tones is left for ever.

Opis:: Struktury przestrzenne i sposoby użytkowania ziemi należy synchronizować z przyrodniczo-gospodarczymi warunkami, stosownie do bytowych i kulturowych potrzeb społeczności lokalnych i regionalnych. Gleba i szata roślinna stanowią biologiczną powłokę lądowej powierzchni ziemi. Bez gleby nie ma szaty roślinnej (fitosfery), tak jak bez szaty roślinnej nie ma gleby (pedosfery). W warunkach naturalnych obie wymienione sfery tworzą względnie stabilną (w czasie) biosferę, stosowną do jakości powierzchniowych utworów geologicznych (petrochemicznych), strefy klimatycznej (w tym klimatu lokalnego) i rzeźby terenu. Antropogenizacja powierzchni ziemi bezpośrednio i pośrednio zniekształca naturalne warunki środowiska. Likwidacja trwałej szaty roślinnej ba potrzeby uprawy roślin odsłania glebę na erozyjne działanie wód opadowych i wiatru oraz nasila dynamikę powietrza atmosferycznego i spływy powierzchniowe wód opadowych. Modyfikuje warunki klimatu lokalnego. Techniczna uprawa gleby czyni ją bardzo podatną na erozyjne działanie wody i wiatru. Techniczna zabudowa trwale niszczy biologicznie czynną powierzchnię ziemi, z daleko idącymi skutkami ekologicznymi. W rolniczej przestrzeni Polski dominują archaiczne struktury gospodarstw chłopskich, o niebywałym rozdrobnieniu powierzchni działek, daleko idąca degradacja systemów melioracji wodnych. Niezbędne scalenia gruntów są realizowane w znikomym zakresie. Leśna rekultywacja nieużytków i nieefektywnych gruntów rolnych, to główny czynnik wzrostu lesistości kraju, począwszy od roku 1949. Dzięki temu lesistość kraju zwiększyła się z około 20% do około 30% w roku 2010. Potencjalne możliwości zwiększenia lesistości są jeszcze bardzo duże, tym bardziej, że znaczna część nie użytkowanych gruntów rolnych została już samoistnie zadrzewiona (zalesiona) i zakrzewiona, czego nie ujmuje geodezja i statystyka.
Spatial structures and land use patterns need to be synchronized with natural and economic conditions, at the same time taking into account social and cultural needs of local and regional communities. Soil and vegetation provide biological coating of land surface, as without soil there is no vegetal cover (phytosphere), and likewise, without vegetation there is no soil (pedosphere). Under natural conditions, both spheres aforementioned constitute the biosphere, relatively stable over time, and adapted to the quality of geological material at the land surface (petrochemical conditions), climatic zone (including local climate) and local relief. Anthropogenic impacts on land surface have direct and indirect effects visible as the deformation of natural conditions. Removal of vegetal cover without subsequent crop cultivation exposes soils to wind and water erosion and enhances the dynamics of atmospheric air and runoff of precipitation waters. It also modifies local climatic conditions. Technical cultivation of soils renders them vulnerable to erosive action of wind and water. Technical build-up irreversibly destroys the biologically active land surface leading to the far reaching environmental consequences. In the agricultural space of Poland there prevail both archaic structures of farmland with an unusual fragmentation of agricultural lots and advanced degradation of water melioration systems. Activities required to perform land merging have only been made to an invisible extent. Forest reclamation of waste land and non-effective agricultural land has been the main factor contributing to an increase in the country's forest rate since the year 1949. It is owing to that activity that the country's forest rate increased from some 20% to about 30% in the year 2010. Potential for increasing the forest rate remains very high still, the more that a considerable part of set aside farmland has been subject to spontaneous afforestation (woods and shrubs), what has not been registered by geodetic and statistical services.

Opis:: Tansy (Tanacetum vulgare L.) grows in moderate area of the northern hemisphere, in Poland – its range covers the whole country. It appears on the farm wastelands, by roadsides, on enbankments, river banks, forest lips and in open spaces. The present paper has faced the challenge of defining the influence of the environmental conditions on the mineral composition of Tanacetum vulgare leaves. The plants were picked in the blooming period from May to September 2017 in 12 natural environments of their growth and at different contamination levels. The dried and minced plant material was submitted to chemical analyses of the bio elements content (K, P, Cu, Zn, Mo) of leaves. A great variety was observed when speaking in terms of particular elements content in dependence on the position. In all tests, significant quantities of K and P were found. The study results point at the very fact that the mineral composition of Tanacetum vulgare leaves is influenced by the environmental contamination, caused by the nearby "neighbourhood" of circulation areas of high traffic volume, factories or patrol stations.

Opis:: Due to the rapid pace of urbanization, the lead-zinc slags previously located outside the settlement turned out to be within the city of Shymkent and began to pose a serious threat to the environment. Therefore, the purpose of the study was to investigate the impact of lead-zinc slags on the environment of Shymkent. It has been revealed that the fields of ruderal plant species are inversely correlated with the lead content in the soil, for phyto-indication of the state of soils, the most informative indicators are the phytocenotic composition and the projective covering of soils with vegetation. At the same time, the proportion of annual species in the control is 53.5 ± 5.6%; with an increase in the toxic load, their role gradually weakens, reaching from 14496.0 ± 105.1 mg/kg Pb2+ to 5.2 ± 0.4%. It was found that Dodartia orientalis, Centaurea squarrosa Willd., Plantago lancetofolium are hyperaccumulators of lead ions, while electron microscopic images showed that lead ions accumulate in the intercellular space of plants, forming significant conglomerates of 10–75 nm. The negative influence of lead-zinc waste has been established, which leads to the accumulation of lead in the blood of children and, as a consequence, is the cause of various diseases. The maximum lead content in the amount of 103 micrograms / dl was found in the blood of children in the area of the city, located 800–1000 m from the slag storage site. Developing hypochromic anemia in children indicates its toxic origin. It was revealed that 90% of children have such pathologies as biliary dyskinesia, dental caries, small anomalies of heart development.

Opis:: The quality of the aquatic environment of high Andean lagoons was evaluated by means of multivariate statistical methods in two contrasting climatic periods. The water samples and benthic macroinvertebrates were collected in 22 sampling sites during the rainy and dry seasons. In each lagoon DO, DTS, EC, temperature and pH were determined in situ. The results revealed that the physicochemical parameters comply with the environmental quality standards for water, except COD and BOD5. In the PCA of the physicochemical parameters, the first two axes explained 73% of the total variation. The gradual analysis in pairs showed significant differences. The SIMPER analysis determined an average of four families of benthic macroinvertebrates per lagoon that showed more than 70% contribution. The ANOSIM revealed that Tragadero lagoon differs significantly from the others. The DistLM showed a value of 0.46 of coefficient of determination. Therefore, the quality of the environment of high Andean lagoons evaluated by means of multivariate statistical methods presents important differences or dissimilarities not only in the physicochemical characteristics of the water, but also in the composition of the benthic macroinvertebrate communities.

Opis:: Na rynku tworzyw sztucznych pojawia się coraz więcej tworzyw opisywanych jako biodegradowalne, oxobiodegradowalne, które mają być całkowicie bezpieczne dla środowiska, mają rozkładać się znacznie szybciej niż konwencjonalne tworzywa, w warunkach naturalnych, np. kompostowania. Informacje podawane przez producentów takich materiałów budzą wiele wątpliwości i kontrowersji, związanych z rzeczywistym rozkładem tworzywa, jego bezpieczeństwem dla środowiska. Calem pracy było przedstawienie najważniejszych informacji, dotyczących tworzyw biodegradowalnych oraz oxobiodegradowalnych, wykorzystywanych jako opakowania na towary, żywność oraz worki na odpady, określenie możliwości rozkładu tych tworzyw oraz zidentyfikowanie problemów, jakie powstają na różnych etapach ich cyklu życia. Zebrane informacje potwierdzają konieczność modyfikacji przepisów i norm dotyczących tworzyw biodegradowalnych i oxobiodegradowalnych, w celu wyeliminowania z rynku produktów, które mogą stwarzać poważne zagrożenie dla środowiska oraz zdrowia i życia zwierząt. Głównym problemem jest rozkład tworzyw w różnych warunkach środowiskowych, które są inne niż ustalone podczas badań w laboratoriach.
On the market of plastics there are more and more plastics described as biodegradable, oxobiodegradable, which are to be completely safe for the environment, have to decompose much faster than conventional plastics, in natural conditions, e.g. composting process. The information provided by the makers of such materials raises many doubts and controversies related to the real decomposition of the material and its environmental safety. The aim of this study was to present the most important information on biodegradable and oxobiodegradable plastics, used as packaging for goods, food and waste bags, determining the possibility of decomposition of these materials and identifying problems that arise at various stages of their life cycle. The collected information confirms the necessity to modify the regulations and standards for biodegradable and oxobiodegradable plastics, in order to eliminate from the market products that may determine a serious threat to the environment and animal health and life. The main problem is the decomposition of plastics under different environmental conditions, which are different than those found during laboratory tests.

Opis:: This research characterizes a natural zeolitic-rich tuff from Yemen (Al-Ahyuq area) and its potential in environmental applications. A total of 40 zeolite samples of Al-Ahyuq area were selected and fully characterized by a variety technique to obtain the mineralogical and physicochemical parameters. Our results show that the purities of zeolite minerals range from 78 to ~100% zeolite. Clinoptilolite and mordenite are the major mineral zeolite whereas heulandite and stilbite occur in minor amounts present in the zeolite deposit. Accessory minerals include quartz, illite, mica, feldspar, kaolinite, and smectite. In addition, the chemical compositions of Al-Ahyuq zeolitic tuffs are found to be comparable with other zeolites compositions of high economic value in the world. Moreover, its environment application was also discussed in this paper.

Opis:: Plastic debris has become a global problem due to its widespread distribution and accumulation in the marine environment. Indigenous bacteria in the marine environment are able to quickly contaminate plastic surface and assemble to form successional plastisphere-specific bacterial. The formation of microbial biofilms on the plastic surface can indirectly initiate the degradation of plastic polymers. The environmental conditions of the tropical region make the growth of microbial biofilms become faster. However, the study on the biodiversity of microorganisms in marine plastic debris is limited to the northern hemisphere, which includes subtropical and temperate regions. This review provides current studies of biodiversity and community structure of plastisphere in tropical environments, including bacteria and microalgae, and their potential to degrade the plastic polymer. A systematic literature search has been conducted using Scopus with different combinations of keywords. In addition, Google Scholar databases were also used to find more studies on some specific topics, including plastic degrading organisms. The climate-associated areas have been grouped according to the latitude of the study site into tropical, subtropical, and temperate latitudes. The microorganisms analyzed in this review are only bacteria, actinobacteria, and microalgae.
