Opis:
The aim of the study was to compare the Noctuidae moth in the environment of farmland in four places, using ecological indices. The study was conducted from 2003 to 2005 on the fields sown with the winter wheat, sugar beets, the maize and the winter rape. The subject of the study was the imago of butterflies caught by light traps. Light traps (Polish brand) located at the Institute of Plant Protection (IPP), Agricultural Experimental Farm - Winna Góra, Sugar Beet Breeding Research Station in Wieclawice, Experimental Station in Słupia Wielka and IPP - Poznan-research garden. The collected Noctuidae imagines were identified and characterized qualitatively and quantitatively. Moreover, the composition of caught of butterflies and its richness was assessed using "abundance relative method", which estimated the number of dominance of species. The Noctuidae imagines were analyzed using Shannon-Weaver's diversity index (H'), Simpson's dominance index (SJ) and Sorenson's indices of similarity (J %). The results showed higher similarity between species composition in agrocenoses of Poznań and Wieclawice. The smallest diversity of species, reflected in the lowest value of diversity index and the high value of dominance index, was observed in a biotic community of the Winna Góra which reveals the species compensation of few Noctuidae kinds. In this case there were: Agrotis segetum (Schiff. et Den.), A. exclamationis (L.), Xestia c-nigrum (L.), whether Discestra trifolii (L.).
Celem pracy było porównanie struktury sówkowatych w środowisku pól uprawnych, czterech badanych miejscowości za pomocą wskaźników ekologicznych. Badania przeprowadzono w latach 2003-2005, na polach doświadczalnych obsianych pszenicą ozimą, burakami cukrowymi, kukurydzą oraz rzepakiem ozimym. Przedmiotem badań były odłowione imagines motyli sówkowatych za pomocą pułapek świetlnych zwanych potocznie samołówkami. Określono skład jakościowy i ilościowy odłowionych motyli, obliczają strukturę dominacji gatunków wyrażoną za pomocą tzw. abundancji relatywnej. Do analizy porównawczej materiału zastosowano indeks różnorodności Shannonna-Weavera (H'), dominacji Simsona (SI) oraz wskaźniki podobieństwa Sorensona (J %). Wyniki badań wykazały większe podobieństwo składu gatunkowego agrocenoz Poznania i Więcławic. Najmniejszą różnorodnością gatunków, potwierdzoną małą wartością indeksu różnorodności oraz dużą wartością indeksu dominacji, charakteryzowała się cenoza Winnej Góry, co wskazuje w strukturze dominacji gatunkowej na kompensację tylko kilku gatunków sówkowatych, w tymi przypadku np. Agrotis segetum (Schiff et Den.), A. exclamationis (L.), Xestia c-nigrum (L.), Discestra trifolii (L.).

Opis:
The aim of the research was the evaluation of the potential contamination with heavy metals in Fluvisols, used as grasslands and arable soils of Vistula River floodplain in the area of the Chełmiński and Nadwiślański Complex of Landscape Parks. The indicators proposed by Håkanson allow to evaluate the potential ecological risk of the contamination with heavy metals associated with the accumulation of one metal or a combination of multiple metals. The mean total content of Cd, Pb, Ni Cu, Zn, Mn, as well as Fe in Fluvisols at the depth of 120–150 cm was assumed as the content of the local geochemical background and it was: 1.0 mg·kg-1, 22.8 mg·kg-1, 26.9 mg·kg-1, 1.4 mg·kg-1, 60.8 mg·kg-1, 591 mg·kg-1, and 17.6 g·kg-1, respectively. The values of the indicators such as contamination factor (CF), enrichment factor (EF) revealed higher levels of the accumulation of heavy metals in the soils of grasslands, which shows that the method of their use has a significant effect on the total metal content. Contamination with heavy metals in the surface layer of the investigated Fluvisols was found, and in terms of the content with cadmium a moderate and considerable potential ecological risk was reported. Due to the fact that no unfavourable effect of trace elements on the riverside environment was proved and that the floodplain areas are under agricultural use, to evaluate the contamination with metals, the limit values for the soils of agricultural land were assumed as stipulated in the Regulation of Minister of the Environment of September 9, 2002. According to that criterion, the soils studied do not qualify as contaminated with metals. Only in one of the soil sampling points the total content of zinc was higher than the one determined as the maximum for agricultural land soils, namely 350 mg·kg-1. A significantly positive correlation was noted between the content of C org and the total content of metals as well as very numerous interactions between metals. The results of cluster analysis confirm that the method of use determines the concentration of metals in the surface layer of the Fluvisols studied.

Opis:
The potential ecological risk index (RI) was employed to evaluate water quality and sediment pollution of heavy metals in the fish Town Rivers, Nigeria. The propensity of the presence of the heavy metals residue in a common brackish water snail (Pachymelania byronensis) that serves as food for human was also examined. Fine-grained surficial sediments from natural depositional zones were collected using Ekman dredge, pooled together and analyzed for the present of heavy metals. The snail samples were randomly hand-picked from the edge of the Rivers or attached to the substrata from August, 2017 to January, 2018 depicting wet season (August - October) and dry season (November - January). A total of 144 P. byronensis (24 per station) were sampled for this investigation. The concentrations of the heavy metals concentration in the sediments and snail tissues were analyzed using graphite furnace absorption spectrometry. The order of occurrence of the metal in the snail is Zn > Cu > Fe > Pb > Cd and their levels remain within their permissible safe levels for human consumption as stipulated by the various regulatory bodies. The risk factor for the metals in the sediments revealed that the Rivers is moderately at risk, which may not pose serious environmental threat and health risks to the resident organisms, but may be magnify along the trophic level. Therefore, sensitization of the inhabitants becomes inevitable, since the level is at threshold, above which may be detrimental.

Opis:
The environmental assessment of the surface water quality of the Western Bug River has been made using the system of classification quality of land surface water of Ukraine in accordance with the approved methodology, which allows comparing water quality of separate areas of water objects of different regions. The calculation of the environmental assessment of water quality has been carried according to three blocks: block of salt composition, block of trophic and saprobic (ecological and sanitary) indicators and block of indicators of content of specific toxic substances. The results are presented in the form of a combined environmental assessment, based on the final conclusions of the three blocks and consists in calculating the integral ecological index. Comprehensive studies of changes in the water quality of the Western Bug River have been conducted within the territory of Ukraine for a long-term period. The water quality of the river on the final values of the integral indicators of the ecological condition corresponded mainly to 4nd category of the 3rd class – the water is “satisfactory” by condition and “little polluted” by degree of purity (except for points of observation that located within the Volyn region, where the water quality corresponded to 3rd category and the 2nd class. It is “good” by condition and “fairly clean” by the degree of purity). Visualization and part of the analysis are performed using GIS technologies in the software of the ArcGIS 10.3.
Środowiskową ocenę jakości wód powierzchniowych Bugu prowadzono z zastosowaniem systemu klasyfikacji wód powierzchniowych Ukrainy w zgodzie z przyjętą metodologią, która umożliwia porównywanie jakości wód odrębnych obszarów z różnych regionów. Obliczenia prowadzące do oceny jakości wody prowadzono w trzech blokach: blok składu mineralnego wód, blok wskaźników troficznych i saprobowych (ekologicznych i sanitarnych) oraz blok wskaźników substancji szczególnie toksycznych. Obliczono zintegrowane wskaźniki ekologiczne i przedstawiono je w formie zbiorczej oceny środowiskowej opartej na wnioskach z trzech wymienionych bloków. Całościowe badania zmian jakości wody w Bugu są prowadzone na terytorium Ukrainy od wielu lat. Zintegrowane wskaźniki odpowiadają w większości 4. kategorii i 3. klasie – woda ma stan „zadowalający” i jest „nieznacznie zanieczyszczona” (z wyjątkiem stanowisk w regionie Wołynia, gdzie jakość wody odpowiada 3. kategorii i 2. klasie. Jej stan jest „dobry” a woda jest „dość czysta”). Wizualizację i część analiz wykonano z zastosowaniem technologii GIS i programu ArcGIS 10.3.

Opis:
Sewage sludge from sewage treatment plants has important soil-forming and fertilizing properties. However, they cannot always be used for this purpose. One of the main reasons why sludge cannot be used for natural purposes is its heavy metal content. Sewage sludge from the treatment plant in Starachowice has been subjected to an analysis of the potential risk of heavy metals, especially in terms of their mobility and geoaccumulation. The calculations were made for the concentrations of heavy metals in sewage sludge taken from the treatment plant in Starachowice and in arable soil from the measurement point at the place of its potential use. Geoaccumulation index (Igeo) and potential ecological risk index (PERI) were calculated. The analysis of the results shows that although the geo-accumulation index and the level of potential ecological risk are high and dangerous in terms of agricultural or natural use of sediments, the percentage of metals has been recorded mainly in the immobile fraction from which they will not get into the soil.
Osady ściekowe z oczyszczalni ścieków mają istotne właściwości glebotwórcze i nawozowe. Nie zawsze jednak mogą być one wykorzystywane do tego celu. Jedną z głównych przyczyn, dla których nie można wykorzystać osadów na cele przyrodnicze, jest zawartość w nich metali ciężkich. Osady ściekowe z oczyszczalni w Starachowicach zostały poddane analizie potencjalnego zagrożenia metalami ciężkimi, zwłaszcza pod względem ich mobilności i geoakumulacji. Obliczenia wykonano dla stężeń metali ciężkich w osadach ściekowych pobranych z oczyszczalni w Starachowicach oraz w glebie ornej z punktu pomiarowego w miejscu ich potencjalnego wykorzystania. Obliczono wskaźnik geoakumulacji (Igeo) oraz potencjalny wskaźnik ryzyka ekologicznego (PERI). Na podstawie analizy wyników można stwierdzi, iż pomimo że wskaźnik geokumulacji oraz poziom potencjalnego ryzyka ekologicznego są wysokie i niebezpieczne pod kątem rolniczego bądź przyrodniczego wykorzystania osadów, to udział procentowy metali odnotowano głównie we frakcji niemobilnej, z której nie będą one przedostawać się do gleby.

Opis:
The extensive nature of natural resource use in the Siret River basin in recent years has led to a significant depletion of its water resources and deterioration of the ecological state of surface waters. The following paper presents the results of assessing the degree of water pollution of the Siret River. A number of biotic water quality indices were used for this purpose. In particular, the Trent Biotic Index (TBI) and the Biological Monitoring Working Party Index (BMWP), both of which use the density ratio of different macroinvertebrate taxa in the aquatic communities, and the Pantlé and Bucca saprobility index, which uses the absolute density and saprobility of indicator species of aquatic organisms. A comprehensive assessment of the aquatic ecosystem of the watercourse was carried out using the water pollution index (WPI). The biological indices were calculated on the basis of data on zooperiphyton communities formed on an artificial fibre media of the «VIYA» type. The VIYA fibre carrier was used for more accurate determination of the species composition and quantitative characteristics of zooperiphyton communities in the studied river sections. The TBI index ranged from 5 to 6 (which corresponds to a water quality assessment of 'satisfactory'). The BMWP index ranged from 8 (very poor) to 32 (good), and the saprobicity index from 1.52 to 1.95 (good water quality). The WPI index at the control sites in the Siret River ranged from 4.6 (which corresponds to a water quality assessment of 'polluted') to 8.1 (which corresponds to a water quality assessment of 'extremely polluted'). Significant differences in the results of the assessment by different biotic indices indicate that these indices cannot be used as indicators for an exhaustive assessment of water quality using zooperiphyton. They can only be used as relative indicators for comparing the state of water pollution at different locations. The values of hydrochemical indicators of water quality at two observation posts of the river were analysed. The maximum permissible concentrations of nitrite ions, ammonium ions and suspended solids in the control sections of the river were found to be exceeded.

Opis:
Coastal areas in Anantigha are utilized as dumpsite for industrial and domestic wastes including effluent from local industries and inhabitants of the area despite their usage for crop cultivation. Thus, the present study was designed to assess the concentration, pollution load and ecological risk of heavy metal in Anantigha coastal area. Standard pollution indices such as contamination factor (Cf), degree of contamination, pollution load index (PLI), enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk index were deployed to assess the level of heavy metals contamination in the area. The results showed that the sediment was acidic under dried conditions and low in conductivity. The mean concentration levels of all the heavy metals were lower than their mean background values except for Al. The orders of dominance for concentration of heavy metals were: Al>Fe>Mn>Cu>Zn (Station 1) and Al>Fe>Mn>Zn>Cu (Stations 2, 3 and 4). Analyzed data showed that the sediments in the area are contaminated with Al with Igeo result showing station 2 and 4 been moderately to heavily contaminated with Al while station 4 was heavily contaminated with aluminium. Station 1 had low degree of contamination, whereas station 2 and 4 had moderate degree of contamination, and station 3 showed considerable degree of contamination. The PLI result indicates unpolluted condition and the area were not enriched by the studied heavy metals as shown by EF values. Hence, the sediment in Anantigha coastal marine area was classified as having low ecological risk factor. However, the levels of these metals are not static; there is tendency for increase as a result of increased human input and activities. Hence, there is a need for regular soil testing.

Opis:
This study aimed to analyze the heavy metal contamination in sediments and their potential ecological risks. The sediment samples were collected using PVC pipes and grab samplers at nine study sites in Youtefa Bay, namely five sites in the mangrove ecosystem, two sites in the estuary, and two sites in the middle of the bay. The heavy metal content was analyzed using Atomic Absorption Spectrophotometry. The results of the analysis of the heavy metal content in the sediment were in the following order: Zn > Cu > Pb > Ni > Cr > Cd > As > Hg (106.077±98.857, 28.553±30.505, 19.798±11.541, 17.665±11.457, 12.103±0.124, 2.996±1.235, 0.149±0.124, and 0.082±0.047 mg kg-1, respectively). Only the Cd content has exceeded the Threshold Effect Level (TEL) at all study sites. On the other hand, the As and Cr content has not exceeded TEL at any study site. The content of Hg, Cr, Pb, Zn, and Ni has exceeded TEL only at a few study sites. The heavy metal content in estuary sites is higher than in mid-bay and mangrove sites, which can provide the information on the sources of heavy metal contaminants. There is a significant correlation for the content of Cu, As, Pb, Cd, Zn, and Ni which can indicate that the sources of these heavy metals are relatively the same (r = 0.569 to r = 0.950). The CF and Igeo values indicate that there has been contamination of several heavy metals studied. Further analysis ( ERI ) showed that the heavy metal content in the sediments poses a potentially serious ecological risk. Most of the potential ecological risks are the contribution of Cd and Hg which have high toxicity factors and this should receive special attention from local governments and stakeholders to prevent higher contamination.

A total of 316 soil samples in the An Giang province were collected from the industrial zone (48 samples), mining (40 samples), farming (112 samples), landfills (88 samples) and cemeteries (28 a samples) to analyze toxic elements, including Cu, Zn, Pb, Cd and As. The geoaccumulation index (Igeo), pollutant load index (PLI) and potential ecological risk index (RI) were used to assess pollution levels and ecological risks. The results showed that the concentrations of heavy metals were almost still within the allowable limits of national standards. Cd was not detected. Heavy metals were detected in the soil in the following order: As < Pb < Cu < Zn, mining < industrial < landfill < cultivation < cemetery areas. The heavy metals contributing to soil environmental variability were similarly identified in the cemetery with industry and landfill with farming. The value of Igeo shows that As has a high potential to accumulate in soil in all land uses. The ranges of PLI values presented that the soil in industrial, farming, mining and landfills areas were classified moderate, while the cemetery areas has been rated at a high level. The RI values identified very high, high, and moderate ecological risks for cemetery, industrial and farming land and landfill, mining, respectively. The combination of PLI and RI indices showed that the cemetery areas were at the highest levels of pollution and risk. The results of this study provide scientific information on pollution level and ecological risks in various land use types supporting environmental zoning and managing strategies in the An Giang province.

The results of the study of the macrophytes of the rivers Turia, Vyzhivka and Tsyr, the right-bank tributaries of the upper reaches of the Pripet River, are presented. The species composition of aquatic and coastal aquatic vascular plants was investigated during the vegetation seasons of 2018 and 2019 at 9 observation points located along the rivers from the source to the mouth. The most numerous species composition, 57 species, was found in the Turia River, 36 in the Vyzhivka River, and 28 species were identified in the Tsyr River. The macrophyte index for rivers (Pol.: makrofitowy indeks rzeczny - MIR) was determined from the results, and the ecological state of the rivers was assessed according to the methodology of the macrophyte assessment of rivers (Pol.: makrofitowa metoda oceny rzek - MMOR). The investigation showed that water quality in the Turia River on sites No. 1, 3 and 4 belongs to class III, satisfactory category. The surface water quality on site No. 2 of the Turia River belongs to class II, a good category. The water quality in the Vyzhivka River on all test sites belongs to class II, a good category, which testifies to favourable ecological conditions for the development of higher aquatic plants along the whole course. The water quality in the Tsyr River on test site No. 8 (Kamin-Kashyrskyi, upper course) corresponds to class II, good category. On test site No. 9 (middle course), the quality of surface waters of the Tsyr River worsens to the class III, satisfactory category.

Opis:
The heavy metal contamination has become a serious problem in the aquatic environment, including marine sediments. This study was aimed at analyzing the content of heavy metals in marine sediments, then assessing and evaluating the level of heavy metal contamination and its ecological risks. The sediment samples were taken using a grab sampler at six sites in the coastal waters of Mimika Regency, Indonesia. The TCLP testing method was used to determine the content of heavy metals in marine sediments. The results showed that the concentrations of Pb, Cu, Cd, and Hg in marine sediments ranged from <0.25 to 0.59 ppm, <0.02 to 0.54 ppm, <0.005 to 0.03 ppm, and < 0.0007 ppm. Only the concentrations of Cu on the Meoga and Puriri sites exceeded the quality standard in the Government Regulation of the Republic of Indonesia No. 18 year 1999. The results of the assessment of heavy metal contamination and its ecological risk potential indicate that the coastal waters of Mimika Regency are included in the category of low contamination and low ecological risks. The concentration of heavy metals in this study shows that the coastal waters of Mimika Regency are not contaminated by Pb, Cu, Cd, and Hg heavy metals.

Opis:
Tendencje społeczeństwa do nieustannego wzrostu gospodarczego w połączeniu ze zmianami demograficznymi doprowadziły dziś do istotnych problemów ekologicznych w skali globalnej, do których należą między innymi: wzrost wykorzystania nieodnawialnych zasobów naturalnych, wzrost emisji gazów cieplarnianych, zanieczyszczenia gleb, wód, powietrza oraz postępująca degradacja ekosystemów. W obliczu tak poważnych zagrożeń niezbędne są globalne inicjatywy wszystkich państw w celu ograniczania skutków nadmiernej konsumpcji. Celem artykułu jest prezentacja metod pomiaru poziomu konsumpcji zasobów naturalnych przez społeczeństwa oraz badanie zależności pomiędzy poziomem rozwoju społeczeństw, a zużyciem zasobów. Jako metodę pomiaru poziomu konsumpcji dzisiejszych pokoleń w odniesieniu do możliwości regeneracyjnych środowiska naturalnego wykorzystano popularny miernik – ślad ekologiczny (Ecological Footprint). Natomiast jako metodę oceny poziomu rozwoju społeczeństw wykorzystano wskaźnik Human Development Index (HDI), uwzględniający trzy podstawowe obszary: oczekiwana długość życia, poziom PKB na mieszkańca oraz edukację. Wyniki badań wskazują, że aktualny trend nieograniczonej konsumpcji krajów wysokorozwiniętych odbywa się kosztem przyszłych pokoleń.
The trends of the society for the continuous growth, combined with the demographic changes, today have led to the important ecological problems on a global scale, which include, among others: the increased use of non-renewable natural resources, an increase of the greenhouse gas emissions, contamination of soil, water, air and the progressive degradation of ecosystems. In the face of such serious threats the global initiatives of all countries are important to limit the results of the excessive consumption. The aim of the article is to present the methods of measurement of the consumption level of natural resources by the societies and the examination of relationships between the level of development of the societies and the use of resources. The popular measure – the ecological footprint – was used as a measurement method for the consumption of the today’s generations in relation to the regenerative possibilities of the natural environment. On the other hand, as the assessment method for the level of development of societies – the Human Development Index (HDI), including three basic areas: the life expectancy, GDP level per capita and education was used. The results of the research indicate that the current trend of the unlimited consumption of the highly developed countries takes place at the expense of the future generations.
