Protected areas are a critical aspect towards safeguarding biodiversity with impacts on climate change and carbon sequestration. This study presents the results of the analysis on the living conditions offered to aquatic birds by the aquatic habitats of ROSPA0143 Upper Tisa protected area and highlights the importance of the aquatic habitats from Teplița for the conservation of biodiversity. Teplița aquatic system registers the largest number of aquatic species (66 out of a total of 68 for the entire protected area), of species that occur only here (22), of those nesting exclusively at Teplița (36.84% of the total nesting aquatic species) as well as the largest populations of aquatic species that are important for conservation. The vegetal carpet that supports the fauna has a simplified structure due to anthropic pressures, being comprised of three types of hygrophilous habitats, but with a high degree of ruderalization. Water quality analysis reveals a slightly more basic pH value for Tisa than for the 3 lakes in the area. Also, high values of dissolved oxygen and oxygen saturation determined for Tisa and the three lakes reflect a good level of oxygenation, above the minimum of 6.5-8 mg·L-1 required for healthy water. In accordance to water legislation, all measured parameters (i.e., alkalinity, Na, NH4+, NO2-, NO3-, Cl, iron) fall within the very good, good, and moderate quality classes. Dissolved copper, however, reveals a degraded water quality for lake 3 with a concentration slightly higher than the legal limit (0.123 mg·L-1).

In the last two decades, the development of satellite technology has made it easier and more convenient to apply remote sensing in warning and solving environmental problems, especially the tracking, monitoring, and evaluation of environmental objects. Algae blooms are one of the top environmental issues of concern today. The blooms cause many harmful effects on the water environment and ecosystems in the area, such as reducing dissolved oxygen levels and producing harmful toxins, causing aquatic organisms to lack oxygen and be poisoned and dead. This study presents the research results in monitoring and calculating the concentration of algae in the Dau Tieng Reservoir by remote sensing. By constructing a regression function between monitoring data and qualitative algorithms from Landsat image spectrum reflection, the study conducted quantification and mapping of the distribution of algae concentration in the Dau Tieng Reservoir area. The calculation results show that the qualitative algorithm 3BDA(3) from the spectral bands in the GREEN, RED, and near-infrared NIR wavelength bands shows a reasonable degree of correlation with the monitoring data. Since then, the author has mapped the distribution of algae concentration and the current status of blooming algae on the reservoir at 3-time points. The study's results show the feasibility of applying remote sensing technology in monitoring, evaluating, and analyzing the concentration of algae in Dau Tieng Reservoir. The calculation results are an essential source of advice in managing reservoir water quality to prevent and minimize environmental and ecosystem damage in the area local water bodies.

The main aim of the article is to investigate the content of nutrients and potentially toxic elements in individual parts of the plant body using the analytical method of energy dispersive micro-X-ray fluorescence spectroscopy (μXRF). As the model species, silver birch (Betula pendula) and European spruce (Picea abies) were selected and sampled at the abandoned Hg-ore deposit Veľká Studňa on the well-known mining territory of Malachov (Central Slovakia). In order to investigate the bioaccumulation mechanism and test the efficiency of the method, the analyses were focused on the several parts of the plant body individually: roots, stems, branches, leaves/needles. Among all elements, Ca was contained in the highest concentrations in all samples. The concentrations of essential elements decreased as follows: Ca > Si > Mg > P > S > Mn; and of potentially toxic elements in order: Zn > Fe > Al > Hg > As > Cu. The article evaluates the efficiency of the presented analytical method for application in plant matrices.

In this study, greenery wastes of Platycladus orientalis (Po) and the other 5 species which are commonly used in urban landscaping were collected. Monospecific greenery wastes and their 1:1 mixtures containing Po waste were used to treat contaminated soil with a petroleum content of 15.00 g/kg, to conduct a 150-day laboratory remediating experiment at 20-25℃, under a soil moisture of 50% of the saturated water holding capacity. The effects of mixed addition of greenery wastes on their re-mediating effects on contaminated soil were detected, to provide scientific basis for the reasonable utilization of greenery waste in contaminated soil remediation. The results indicated that: (1) Mixed addition of Po waste with Picea asperata (Pa), Acer truncatum (At), Ginkgo biloba (Gb) or Juniperus formosana (Jf) waste significantly enhanced their effect of removing petroleum contaminants, espe-cially for removing aromatic and non-hydrocarbon substances; while the mixed addition of Po waste with Pinus tabuliformis (Pt) waste significantly weakened their remediating effects. The mixed addition of Po waste with Gb or Jf waste significantly enhanced their effects of replenishing soil available N and P; the mixed addition of it with Pa, Pt, Gb or Jf waste tended to enhance their effects of stimulating the activities of soil invertase, urease, phosphatase and dehydrogenase, while the mixed of it with At waste tended to weaken their simulating effects. (2) Mixed litters with high contents of C, N, terpenoids and amino acids, and chemical dispersion facilitated the degradation of petroleum contaminants, while those with high contents of soluble saccharides and total organic acids/terpenoids led to contrast effects; mixed litters with high N content facilitated the increment of soil enzymatic activities, while those with high contents of total organic acids and terpenoids led to contrast effects. In conclusion, mixed addition of Po and Jf, Po and Gb, and Po and Pa wastes might enhance their overall remediating effects on petroleum contaminated soil, while mixed addition of Po and Pt wastes might weaken their ability of removing the contaminants, and this mixing form of greenery wastes should be avoided.

Contents and spatial distribution of heavy metals (Zn, Cu, Cd, Ni, As, Pb, Al and Ba) in the fine fraction of surface sediments and in Zygophyllum album shrub of zones influenced by phosphate industry in the region of Gabès, as well as in a control site (Sidi Ejjehmi) were determined. For the assessment of the level of sediment pollution, several parameters were calculated, including enrichment factor (EF), contamination factor (CF), Pollutant Load Index (PLI), Risk factor (Er), potential ecological Risk Index (Ri), Geoaccumulation Index (Igeo), Electrical Conductivity (Ec), Organic Matter (OM) and pH.Whereas, Bio-Concentration Factors (BCF) and Translocation Factors (TF) are calculated for the evaluation of pollution degree in Zygophyllum album. The soils of Gabès are characterized by a high average relative concentration of As, Ba, Cd, Cu, Ni, Pb, Al and Zn in all the study sites, indicating contributions from anthropogenic sources. The Igeo and the PLI of heavy metals show that all study sites are heavily polluted. All the EF values of all trace metals from Gabes sites (above 10), indicate a very significant enrichment in soils. The PCA, AC and correlation matrix suggest that soils are mainly polluted by As, Ba, Cd, Cu, Ni, Pb, Al and Zn. For all studied metals, the values of TF in Z. album from Gabes sites are greater than 1 except for Al at S2. All metals studied, except Cd, are more accumulated in shoots than in roots. Values of BAF are greater than 1, as well as TF values are greater than 1, so Z. album of Gabes can be considered as phytoremediator in the case of those studied metals. For Cd, TF is greater than 1 and BCF is less than 1, Z. album can be considered as a phytostabiliser for this metal.

In this article, we aimed to analyse and evaluate the alkaline metals (such as Li, Cs, and Rb) enrichment in the lacustrine and volcanoclastic sediments of the Erdőbénye valley basin of north eastern Hungary using a field spectrometer and ICP-MS analysis methods in order to define a potential explo-ration target. The results are ambiguous and the consequences are summarized in this article. Alkaline metals such as Li, Cs, and Rb are essential for the 5G technology, production of batteries, various ceramics and glass products, as well as other crucial application areas in the current world. As a result, the demand for those elements is skyrocketing on a world-wide. A potential target area was selected to test the applicability of LIBS field spectrometer in this segment of industrial mineralization.

Photosynthesis, the process by which green plants synthesize carbohydrates from the carbon dioxide available in the environment using light energy as a fixed energy source with the help of photoassimilate pigments, underlies all food chains in nature. The good functioning of plants (in this paper, spontaneous and cultivated taxa of the genus Taxus L.) in their vegetation areas is influenced, at the same time, by the level of their relationship with the environment regarding water exchange, as a vital factor for the existence of the vegetation cover on Earth. As a result, the basic physiological processes (photosynthesis, transpiration) depend to a large extent on the anatomical and micro-morphological characteristics of their leaf apparatus, on certain internal factors relating to the leaf surface, and on a series of external factors, which manifest themselves in the environment of the taxa concerned, to which they have developed specific morpho-structural and functional adaptations.

Water scarcity, unequal access to water resources, and the impact of climate change on water availability are among the major global environmental concerns. As dynamic and vulnerable water subjects, rivers are constantly exposed to the pressure of natural conditions variability (primarily climatic) and direct anthropogenic influences. Therefore, it is necessary to investigate river regime dynamics over longer periods to adapt the water management sector, and human demands to any observed variations in river discharge. Observing the periodicity or cyclicity of the occurrence of certain discharge values is an important topic of modern physical geography and hydrology research. Statistics and hydrologic modelling provide great opportunities for observing cyclicality and forecasting future trends. The aim of this paper is to indicate the importance of specific statistical methods of autocorrelation and spectral analysis to study the repeatability of mean annual and maximum discharges. The South Morava River in Serbia (HS: Mojsinje, Korvingrad, Grdelica) has been selected as a case study. The obtained results (period: 1924-2021) indicated the significant cyclicity of mean annual discharges, especially pronounced at the upstream hydrological station Grdelica (3.5-year cycle) and downstream hydrological station Mojsinje (19.5-year cycle). These cyclicities are mostly influenced by variations in the amount of precipitation received from the upper part of the river basin (R > 0.6). In contrast, no regular cycles of maximum annual discharge values were determined in the studied period. The obtained results can be important for future detailed geographic and hydrologic studies as well as for the development of strategies and plans in the field of water management, environmental protection, spatial planning, prevention of floods and droughts, etc.

Research on microplastic in coral ecosystems in Indonesia is infrequent. This research will observe Microplastic on the coral reef dive tourism in Tidung Island, Kepulauan Seribu, Jakarta Bay. The number of microplastics varied between 60 to 340 particles/kg dry weight. Fiber was the most microplastic type found in all stations; it ranged from 67% to 100%. Size of microplastic found in this study ranged <100 to >1100 𝞵𝞵m. We found four types of polymers (polybutylene, polyethylene, polypropylene, and polyester) with the highest percentage of polyethylene at 61.76%. We assume that microplastics observed in coral reef sediment on Tidung island originated mainly from anthropogenic sources. Waste management must be tightened and enhanced in the Kepulauan Seribu and neighboring areas, such as the western area of Java Island and its adjacent areas.

In Perundurai Taluk, which is part of Tamil Nadu's Erode District, the adequacy of underground water for agricultural use was evaluated. Numerous tanneries, chemical plants, textile factories, and dyeing facilities are located close to Perundurai. These industries directly discharge their effluents into the groundwater, which then becomes contaminated. To determine the suitability of subsurface water for agricultural use, groundwater samples from 15 villages were analyzed over the course of two seasons. The appropriateness of the groundwater's chemical type was determined by interpreting Piper trilinear diagrams. It demonstrates that underground water is more alkaline. Most groundwater samples fall into class 4 and Seenpuram falls into class 2, as shown by the USSL Staff diagram. The test results indicate that contamination in the Seenapuram is more due to SIPCOT which poses a potential risk to both agricultural soils and the local population in that area.
