The subject of the research involved the agricultural farms from the Przysucha county (Masovian Voivodeship, Poland). The assessment of ecological results from farms was the purpose of the thesis. Evaluation was made by using selected indicators: minerals balance, soil's organic substances balance and vegetation cover of soil's index. The research was carried out among 100 chosen agricultural farms, situated on light soil, i.e. rye soil. The ecological assessment of the examined farms showed that all of minerals balances (N, P, K) and soil's organic substances balances were positive. In the case of nitrogen, balances exceeded the limit value 30 kg N·ha-1. Vegetation cover of soil's index, as regards arable land, did not reach the recommended value, i.e. at least 60%. However, the cover of utilised agricultural area soil was similar to the recommended level (>70%). That was because of the large orchards and permanent crops share in horticultural farms, as well as large permanent grassland share in bovine and mixed farms.

The ecosystems offer to the socio-economic system a series of goods and services derived from their processes and biodiversity. Ecosystem services offered by a river are at their highest potential when the river status is close to the natural one. Once the river is affected by human impact due to resources exploitation, hydro technical works, water abstraction or improper land use, the ecological status declines and the ecosystem services become scarce. This is why an ecological assessment is necessary in order to establish the connection between the ecosystem services and the human impact. In this paper, the ecological assessment of Timiș River was done, allowing the classification of the river in four sectors with different ecological statuses, associated with the various human impacts that differently affect the quality of the water, the riverbed and the flooding area.

The Coastal region of Diu is the natural habitat dominated by Avicennia marina mangrove species at the southeast coast of Saurashtra in Gujarat state of India. However, Diu being a famous industrial and tourism place survival of these mangrove species is threatened due to anthropogenic activities. In present studies, sediment and leaf samples of A. marina were collected from the Diu coast to evaluate the ecological threat of heavy metals accumulation in the marine habitat. There was remarkable presence of heavy metals such as copper, nickel, cadmium, chromium and lead in sediments and leaf samples of A. marina. The values of Biological concentration factors (BCFs) of heavy metals in leaf samples were high for cadmium, chromium and lead which suggest chelation of these heavy metals with biomolecules. The geo-accumulation index suggested that Site-4 and Site-5 were heavily contaminated with copper and nickel. The ecological risk index suggested that there is no significant effect of heavy metals on growth of plants in the mangrove ecosystem. Principal component analysis revealed that the samples collected from the natural habitats (Site-4 and Site-5) near the fishing and industrial areas were the main sources of heavy metal contamination. Hence, it was concluded that the concentration of heavy metals in the studied ecosystem had limited impact on growth of plants at Site-1, Site-2 and Site-3. However, growth of plants at Site-4 and Site-5 were threatened due to the toxic effect of copper and nickel present in its sediments.

W artykule przedstawiono zwięzłe sprawozdanie dotyczące chronologii oraz działalności Międzyrządowej Platformy Polityki Naukowej w sprawie Różnorodności Biologicznej i Usług Ekosystemowych (IPBES). Organizacja ta przywiązuje szczególną wagę do globalnego stanu różnorodności biologicznej, trendów i aktywności politycznej. Artykuł prezentuje uogólniony obraz rozwoju i osiągnięć IPBES w trakcie jego istnienia. Raporty IPBES ze względu na swoje znaczenie są uznawane i aprobowane na całym świecie. Jednak rozpoznawalny sukces IPBES jest niweczony przez sytuację finansową IPBES. W efekcie istnieje stan, która prowadzi ostatecznie do wniosku, że zawsze następuje hamowanie finansowania wspólnego dobra.

Macrophytes are one of the main components of the aquatic ecosystem. They are used in several countries as metrics for the ecological assessment of hydrosystems. The objective of our study was to evaluate the suitability of the Macrophyte Biological Index for Rivers (IBMR) to determine a trophic level in the upper Oum Er Rbia basin (Morocco) and to understand physicochemical parameters of water that govern the distribution of macrophyte species. CCA analysis was used to relate the distribution of macrophytes to hydrochemical parameters of water. The CCA analysis shows that the distribution of macrophytes was more correlated with abiotic parameters (EC, WT and DO) than nutrient parameters (PO4-P, NO3-N, NO2-N, NH3-N and CODMn). The recorded values of IBMR in the upper Oum Er Rbia basin indicate that the trophic level of the studied rivers ranged from “moderate” to “very high”. Pearson’s correlation coefficient showed that the IBMR is more correlated with the abiotic parameters such as WT and EC and does not show any significant correlation with the content of PO4-P and NH3-N in water, which makes the IBMR index unreliable for assessing the trophic status related to phosphate and ammonia concentrations in our lotic waters.

Within the scope of the work completed has been an ecological assessment of self-curing quartz moulding sand in which the binding system was composed of the Askuran FH 040 furane resin and the Härter GS II curing agent. The test mould has been poured with silumin and grey iron. The analysis results for a water extract from the waste and the results of direct analysis of a waste sample provided the basis of ecological assessment of the waste. The wastes have been qualified under the codes of 10 09 05 and 10 10 05. The discussed codes have not been include in the list of hazardous wastes.

It has been investigated the ecological status of the cooling pond of Zaporizhzhya Nuclear Power Plant (NPP) on the hydrochemical and toxicological indicators. The ecological water quality by most hydrochemical and hydrophysical indices corresponds to the class II, category 3, and is characterized as "fairly clean". However, according to the BOD5 index, the water quality is "satisfactory" (class III, category 4). By the contents of both nitrogen of nitrates and phosphorus of phosphates the water quality belongs to the class IV, category 6, as "bad, dirty water". The main anthropogenic pollutants are copper, iron, zinc, and fluorides. The ecological characteristics by their concentrations in the water correspond to the class III, and categories 4–5 of quality, which are "poorly and moderately polluted" water. Accumulation of toxic metals in the surface layer of the reservoir bottom sediments depends on their types, the minimal content is found in sandy sediments, and maximal one is in muddy sediments. The possibility of significant secondary pollution of the water environment by toxic metals is small under the hydrophysical and hydrochemical conditions typical for the cooling pond of Zaporizhzhya NPP. According to the calculations, the value of the average chemical index of ecological quality is "2.5", which characterizes the water of the Zaporizhzhya NPP cooling pond as "good" and "clean".

In order to evaluate the ecological health condition of Zhanghe River Watershed, an adapted Benthic Index of Biotic Integrity (B-IBI) was developed. Macro-invertebrates were sampled at 12 monitoring stations which were grouped into two condition categories (reference and impaired stations) according to the level of degradation. A total of 47 benthic macroinvertebrates taxa were identified, in which aquatic insects 33 taxa, Mollusca 8, Annalida 3 and Crustacea 3 taxa. Based on macro-invertebrate assemblages characters of this area, 18 candidate biological metrics in four categories, including taxonomic richness, community composition, pollution tolerance, trophic guild, and value distribution, were chosen. In which, four metrics were excluded because of low values or narrow distribution range. Discriminatory power between reference and impaired stations was analysed using box-plots, and six metrics were excluded because the medians of the box-plot inside the inter quartile range. Of all the rest eight metrics, four were not suitable for B-IBI index system because of their high Pearson correlation (| r | 0.75). Finally, total taxa, percentage of Crustacea and Mollusca, percentage of tolerant taxa and percentage of predators were screened out to form a B-IBI index system. Ratio scoring method for B-IBI index was used to get a uniform score. Evaluation criterion was established based on the 25 percentiles value of reference stations. Assessment results using B-IBI showed 5 of sampling stations were in ‘healthy’ and ‘sub-healthy’ state, 3 were in ‘fair’ state, and 4 were in ‘poor’ or ‘very poor’ state of the whole watershed.

The deterioration of the natural environment in the cities and the awareness of multi-faceted benefits from 'green' urban investments led to a new view of the areas covered by vegetation, especially wooded spaces in urban areas. They are now more and more seen as 'one of the main catalysts of urban regeneration, adhesives, which can tie together fragmented elements of modern growth processes into strong structures that can act as stimulators of investments, which in turn will encourage to internal development' (Simson, 2005). This assessment is the result of joint findings of scientists from 21 European countries and was made after analysing many examples of urban development in different countries and successful innovative urban investments in which green areas were the priority issues stimulating the growth. It was stated that the implementation of investments in this light can serve as an inspiration to revive the activity and free social initiatives, particularly in the areas of economic stagnation. New understanding of the role of the natural environment is a challenge for landscape architects and specialists in all related professions (arborists, gardeners, foresters, etc.) and for spatial planners to prepare relevant information materials aimed at both professionals and citizens. It is also necessary to develop appropriate legal instruments and organisational and technical tools in the form of guidebooks and standards based on new knowledge for the creation of conditions for the implementation of a new method of shaping the cities according to the vision of the 21st century in practice. These are urgent actions requiring consolidation of the whole professional environment and close cooperation with authorities and the local community. This is extremely important because, despite the more broadly understood importance of green spaces in the spatial structure of cities, economic categories enclosed within the narrow limits of profits and losses are still predominate in today's thinking of decision-makers. This means that the budget funds for the development and maintenance of green areas are cut in the first place, treated not as a value, but only as a burden and a field generating expenses from a limited pool of municipal budgets. In the face of this situation the Institute of Spatial Management and Housing (IGPiM) have undertaken a number of studies in order to identify the factors stimulating and limiting the development of urban green areas by using the SWOT analysis (Sitarski et al., 2011). Multi-disciplinary studies on the impacts of green areas on the condition of the urban environment, including the local climate and the change of elements of this environment in areas of strong pressure of communication nuisance, were also conducted (Szczepanowska (ed.) et al., 1984). A method was developed for determining the value of trees on the background of vast studies of the methodology of valuating urban wooded areas in many European and non-European countries. Materials for improving the investment activity, including the protection and development of the natural environment, in line with the New Charter of Athens are also being prepared. This paper aims at implementing the priorities set out here for practical use. These issues will be presented in the second part of the article discussing the problems of the new presentation of green areas in the spatial structure of urban areas.

Certyfikacja polega głównie na wielokryterialnej ocenie budynków, w tym również ocenie hałasu i komfortu akustycznego. W polskim prawodawstwie komfort akustyczny jest traktowany dużo mniej rygorystycznie niż np. komfort termiczny i oszczędność energii. Podczas projektowania tzw. zielonych budynków, przede wszystkim biurowych czy oświatowych, przywiązuje się pewną wagę do takich parametrów jak czas pogłosu czy wskaźnik transmisji mowy. W artykule omówiono parametry akustyczne wymagane w ocenie ekologicznej. Spośród wielu powszechnie stosowanych systemów na świecie zaprezentowano brytyjski system BREEAM oraz amerykański system LEED.

Certification is mainly based on multi-criteria assessment of buildings, including the assessment of noise and acoustic comfort. In the Polish legislation, acoustic comfort is regarded considerably less strictly than, for example, thermal comfort and energy savings. However, in the process of design of so-called “green buildings”, in particular office and educational buildings, some importance is attached to parameters such as reverberation time or speech transmission index. The article presents the required, in the environmental assessment, acoustic parameters. Among the many commonly used systems in the world, two were selected for discussion: the British system BREEAM and American system LEED.
