Opis:
This data article aimed to evaluate the influencing mechanisms of the nutrients and the level of eutrophication in the Yangtze River estuary. The seasonal characteristics of nutrients (dissolved inorganic nitrogen (DIN), SiO3-2–Si, and PO43-P) in the seawater of the Yangtze River estuary were analyzed by conducting surveys in spring and summer of 2019. The findings revealed that the concentrations of all nutrient at the surface and bottom layers were lower in spring compared to summer. NO3–N was typically the major form of DIN. Runoff was identified as the primary source of DIN and SiO32−–Si, while PO43−–P originated from a various sources. The SiO32−–Si, while PO43−–P values in the surface and bottom layers during the spring and summer were higher than the Redfield values, indicating an imbalanced nutrient distribution. Furthermore, discrepancies were observed in the distributions of DIN/PO43−–P, SiO32−–Si/DIN, and SiO32−–Si/PO43−–P in the Yangtze River estuary. Through an examination of the ratio of DIN/PO43−–P absorbed by phytoplankton, PO43−–P was identified as a potential limiting factor for nutrition in the sea area of the Yangtze River estuary during spring and summer. The Eutrophication Index (E) values for both spring and summer were found to be higher than the eutrophication threshold, indicating severe eutrophication in the studied sea area.

Opis:
The aim of this study was to determine the content of phosphorus and nitrogen in the bottom sediments of the Poraj Reservoir located on the Warta River, along with defining their spatial distribution and the relationship between these elements and organic matter, aluminum and iron. Samples of bottom sediments were collected on the basis of regular measurement grid of 46 points located in the area of the water reservoir Poraj. The collected samples were analyzed in terms of content of following elements, which values are in range: total phosphorus (TP) 0.06 – 5.06 g/kg, total nitrogen (TN) 0.17 – 9.66 g/kg, organic matter (OM) 0.49 – 28.41% of solid content, aluminum (Al) 2.44 – 145.15 g/kg and iron (Fe) 0.28 – 16.50 g/kg. By using of GIS system, spatial distribution of obtained results of laboratory analyzes were interpolated (Inverse Distance Weighted method was used). On basis of spatial distribution it was noted that in northern part of water reservoir bottom sediments have greater values of TP, TN and OM than in southern part. The study also included calculation of correlation between: OM and TN (n=46, R2 = 0.9335), TN and Fe (n=46, R2 = 0.8782), TN and Al (n=46, R2 = 0.8629), OM and Fe (n=46, R2 = 0.8243), OM and Al (n=46, R2 = 0.7981), TP and Fe (n=46, R2 = 0.7456), TP and Al (n=46, R2 = 0.6209). The presented pilot studies show that the potential content of phosphorus, nitrogen and organic matter in the sediments of the water reservoir Poraj can reach a significant level. The need to plan and carry out further research allowing the evaluation of the properties of the analyzed elements and examining their potential impact on water quality in the tested water reservoir was stated.

Opis:
Jeddah is the most industrialized city on the west coast of Saudi Arabia and is under increasing influence of human activities. Heavy metals data were obtained from four near-coast Red Sea sediment cores in close proximity to Jeddah. Chromium, manganese, iron, copper, zinc, and lead were analyzed from depth-resolved sections of each core via heavy acid digestion and inductively coupled plasma-mass spectrometry (ICP-MS). The average concentrations of all four sites were 245.96 mg kg1, 478.45 mg kg1, 8506.13 mg kg1, 251.82 mg kg1, 623.09 mg kg1, and 362.75 mg kg1, respectively. The depth-resolved results showed that highest concentrations of Mn, Cu, and Pb were found in the top 15 cm of the core profile distributions compared to other depth sub-samples. Heavy metal concentrations in core sediments are increased near central Jeddah and have become higher in recent years. The results of enrichment factor calculations indicate little anthropogenic supply of Mn and Cr while Pb, Zn, and Cu show strong anthropogenic input. The Pollution Load Index was higher in the two sites closer to central Jeddah where power and desalination plants and wastewater release are known. This indicates that the area has suffered from heavy metal pollution compared to other non-industrialized sites in the Red Sea. Heavy metal contaminations due to anthropogenic activity should be taken into account to protect the Red Sea during future growth. The results of this work should be considered as a baseline for heavy metals monitoring in the sediments of the Red Sea coast near Jeddah, Saudi Arabia.

Opis:
The cycle of gonad development and related changes in the length structure and spatial-temporal distribution of ninespine sticklebacks (Pungitius pungitius L.) in Puck Bay were studied. Observations were carried out in the shallow shore zones, as well as in the deeper epipelagic zone of the Bay. Ninespine sticklebacks reproduce in the brackish environment of Puck Bay, breeding in its warmer, inshore zones. Reproduction takes place in the spring and summer months, from April to July. One female spawns several clutches of eggs during one breeding season. The average length of ninespine sticklebacks in Puck Bay was about 40 mm, and the sex ratio in the population was close to 1:1. However, both length structure and sex ratio were subject to local and periodic variations, resulting from possible breeding-related territorial divisions. Higher gonadosomatic indices in females in early spring represented the transition of fish to the advanced vitelligenous phase. The lowest GSI of males during the breeding season indicated the termination of spermatogenesis. The completion of spawning in August started a new process of gonad restoration to prepare the fish for the next breeding season.

Opis:
Four soil profiles were collected from locations with different distances (5, 50, 250 and 1000 m) from a uranium mill tailings dam, Guangdong province, China, to investigate the pollution status of the soil in mining/ milling-related areas based on the contents of uranium (U) and thorium (Th), thus to understand the impacts of uranium industrial activities to the surroundings. The U and Th concentrations were determined by inductively coupled plasma mass spectrometry (ICP-MS) after conventional HF-HNO3-HClO4 digestion procedures. The results indicate that the soils within 50 m from uranium tailing were severely contaminated; those in 250 and 1000 m soil samples were observed to be with local background level even though these in 250 m had slightly higher U/Th ratios. Uranium concentrations varied from 5.50 ± 0.27 to 160.55 ± 8.03 mg/kg, with maximum values recorded in an intermediate layer of the 5-m distance soil profile. In comparison, the concentration of Th ranged from 6.02 ± 0.30 to 84.71 ± 4.24 mg/kg, with maximum values observed in the top layer of the 1000-m distance soil profile. The U/Th ratio varied from 0.15 to 11.99 compared with 0.20, 0.22 and 0.26 of the average for Guangdong province, national China and the world, respectively. The mean U/Th of four soil profiles showed a reduction with distance from the uranium mill tailing dam, suggesting the relatively large magnitude of uranium elevation in soils within limited distances.

Opis:
The aim of this study was to assess the spatial distributions of total trace elements content in the bottom sediments of Dzierżno Duże water reservoir, along with the comparison of the accuracy and characteristics of Kriging and IDW interpolations. On the basis of regular measurement grid consisting of 53 points, bottom sediments samples were collected. Mean values of total trace elements content in bottom sediments of Dzierżno Duże were as follows: Zn – 410 mg/kg, Pb – 57 mg/kg, Cr – 36 mg/kg, Cu – 40 mg/kg, Cd – 5 mg/kg, Ni – 16 mg/kg and Ba – 267 mg/kg. According to the geochemical quality classification, the concentrations of Cd in 32% of samples were assigned to class IV (heavily contaminated), 45% to class III (contaminated), Zn in 42% samples to class III with 1 sample in class IV and 26% to class II (slightly contaminated), Pb in 9% to class III and 58% to class II, Cu in 4% to class III and 68% to class II, Cr in 17% to class II, Ni in 55% to class II, Ba in 8% to class III and 61% in class II. Coefficient of determination was determined between each case of trace elements content. The highest correlation (R2 in range from 0.81 to 0.96) was observed between Zn and Pb, Zn and Cu, Zn and Cr, Zn and Ni, Pb and Cu, Pb and Cr, Cu and Cr, Cr and Ni. Significant correlation (R2 in range from 0.70 to 0.80) occurred between: Zn and Cd, Pb and Ni, Cu and Ni, Cd and Ni. The lowest correlations (R2 in range from 0.25 to 0.70) were observed between concentration of Ba and the rest of trace elements. Two different interpolation methods were chosen for the purpose of generating spatial distributions – Inverse Distance Weighted and Ordinary Kriging. These methods were chosen for purpose of obtaining optimal accuracy result of spatial distributions. The distributions of trace elements content were classified by means of geochemical criteria. In the case of accuracy comparison between IDW and Ordinary Kriging, the former had slightly better results in terms of mean value and root mean square. The generated spatial distributions allowed to determine the most contaminated areas, which were mainly northern-central and southern-central parts of water Dzierżno Duże reservoir.

In this paper we present the results of direct observations of the morphology and size of phage-like particles by means of transmission electron microscopy (TEM) as a function of their spatial distribution in the shallow highly productive Curonian Lagoon of the Baltic Sea. In total, 26 morphologically different forms of phagelike particles were found. Different trends of distribution in terms of abundance, size and shape of virus-like particles were demonstrated. The total abundance of viruses varied from 1.91×107 ml−1 to 5.06×107 ml−1. The virus to bacteria ratio (VBR) changed from 15.6 to 49 and was negatively associated with total bacterial numbers (r = −0.60; p < 0.05). The phages of family Myoviridae were the most diverse and were dominant at all stations.

Opis:
One unintended consequence of nitrogen use in agriculture is an increase in nitrate content in ground waters. Nitrogen content was evaluated in soil samples from specific hydrographic regions of Poland from the 60-90 cm soil layer, in which this nutrient is not readily available to the main root mass of crop plants and may negatively affect the environment. It was revealed that Nmin content in specific hydrographic regions was highly dependent on both the soil type and land use. Notably higher values of Nmin content were observed for organic soils. The highest N contents were found in the grasslands of the northwestern area of Poland, while they were slightly lower in several regions of the main Odra River catchment and west of the Vistula River. The area with a high Nmin content in soils under maize was significantly larger compared to the grasslands area and primarily included the hydrographic regions of the Odra River basin in its south-western stretch, and of the Vistula River on its western and south-eastern side. With regard to the arable land under mixed cereals, the soils with the highest Nmin content in the non-root layer were predominantly located in hydrographic regions belonging to the main Odra catchment and to the catchment of the Vistula River in its upper course.

Opis:
The Klimkówka Dam Reservoir is situated on the Ropa River in southern Poland. The surface area of the reservoir is about 306 ha and its capacity is 43.5 hm3. Acoustic surveys were conducted both in the daytime and at night using a SIMRAD EY-500 split beam 120kHz echo sounder. Maps of the spatial distribution and density of fish were drawn up, and the fish species structure, size, number and biomass were estimated based on acoustic surveys and supervised net catches. The highest fish density at night occurred in the river tributary zones (836 fish/ha). In this area at night fish density was twice as high as in the central region of the reservoir. The density figure for the whole reservoir was 638 fish/ha and was 1.4 limes higher than that in the Solina Reservoir and from ten- to twenty-fold lower than in several other studied lakes. Fish catches performed with pelagic trawIs and net sets revealed the presence of nine fish species. Lake and river trout species which had been introduced to the reservoir were not noted. The fish biomass was estimated to be 11.5 tons, or 44.4 kg/ha, and was from three to 14 times lower in comparison to the estimated figure in several other lakes.

Industrialization is a process which is based on precise and quantitative measurements and contains different basic changes in the economic structure of a country or region. The structural characteristics and spatial distribution of the industrial enterprises established during the industrialization process which is one of the most important elements of the socio-economic transformation in Turkey within a historical process has been the object of this study. The aim of the study was to establish the positions and significance of one thousand (1000) large industrial companies in the industry of Turkey by using the framework of criteria based on sales from production which have been maintained by the Istanbul Chamber of Industry on a regular basis. The workplace and number of employees of the companies on a province basis, sector based division, realized exports and sales from product output, corporate entities, structures, spatial distribution and other characteristics were taken into consideration in the study. Although the thousand large scale companies in Turkey based on production output sales comprised only0.40% of the enterprises active in the industrial sector in 2012, they comprised 12% of the labor force,59.6% of product output sales and 65.2% of all exports. On a regional basis, 54% of these companies are located in the Marmara region, 13.2% are located in Central Anatolia and 12.4% are located in the Aegean region; on a province basis, 63.4% are located in Istanbul, Izmir, Bursa, Kocaeli and Ankara. A sector based division of the companies shows that 21.4% are involved in food, beverage and tobacco processing, 19.6% are involved in the industry of metal goods, machinery, automotive industry, electrical tools and equipment and 16.1% deal with textiles, ready-to-wear, leather and the manufacturing of shoes. In terms of labor force numbers, the figures vary as 18.9%, 27.4% and 17.9% respectively.

The aim of the studies was determining the spatial distribution of premises and the technical means of production resources on farms in the years 1996, 2002 and 2010. The database has been developed for 36 counties of the Śląskie voivodship. The spatial database developed for the analysed voivodships assumed a county as the smallest indivisible unit of the geographical space. The data describing the technical means of production on farms were obtained from inquiries conducted by the European Statistical Office. Diagnostic variables describing the technical equipment on farms included: self-propelled machinery, tractors and usable areas. The analysis of spatial distribution was conducted for the assumed period of time and spatial changes were determined. On the basis of the analysed diagnostic variables the synthetic indicator was determined, which described the multivariate phenomenon by means of one variable. The analysis show that in 1996 agricultural farms were better equipped on the level of the measure of development 0.306 than in 2002, when the measure of development was lower by 0.100.

Opis:
Atmospheric pollution in Ukraine has become a significant environmental problem, especially in the eastern part where heavy industries are located, and it is particularly severe in industrial centers such as; Zaporizhia, Kryvyi Rih, Dnipropetrovs’k and Dniprodzerzhyns’k. The main emission sources are ferrous metallurgical plants and the coal industry. The purpose of this project is to estimate the degree of pollution from dioxides of nitrogen and sulfur in the south-eastern part of Ukraine using satellite data. An assessment of atmospheric pollution by NO2 is carried out using the data from satellite spectrometer EOS/OMI, and information products Level 3 from Goddard Earth Sciences Data, (GES DISC) NASA for 2009-2014. According to the results study, the largest area of propagation of SO2 aerosol was observed in the industrial agglomerations of Kryvyi Rih, Dnipropetrovs’k and Vilnohirs’k.However, a somewhat smaller content of NO2 in the air recorded near the town of Kryvyi Rih and the cities of Vilnohirs’k and Zaporizhia.The results obtained from this research will aid the creation of awareness among Ukraine’s policy makers about the need for air pollution abatement, and also serve as a stepping stone towards addressing the negative impacts of acid rains.
