Pharmaceuticals are part of the emerging pollutants class found in aquatic ecosystems. The presence of these contaminants in the aquatic ecosystem can have harmful effects on living organisms due to their toxicity and ability to accumulate in tissues. In this study, water samples taken from stations located in the Lower Danube River Basin were analysed in order to identify and quantify some classes of pharmaceuticals. To confirm the presence of pharmaceutical traces in surface water samples, a High-resolution UHPLC-MS/MS was used. The obtained results demonstrated that the most frequently identified pharmaceutical residues in the water samples were: caffeine > carbamazepine > metformin > sulfamethoxazole > trimethoprim > clindamycin > ketoprofen > diclofenac > clarithromycin. The highest recorded concentration was 118.52 ng/L for caffeine possibly due to the presence of this compound especially in drinks and food and to a lesser extent also in medicines and the lowest value was 0.36 ng/L for trimethoprim.

Water resource conservation and management is vital as well for humankind, as for nature and economy, and is exposed to anthropogenic and climatic pressures, transcends national boundaries. The EU Water Framework Directive 2000/60/EC establishes a legal framework to protect and restore clean water in the EU and to secure its long-term sustainable use and mitigate the effects of floods and drought. In this regard, EU member-states are developing river basin management plans based on current characteristics and water status and programs with measures. In the planning process were identified different types of pressures on the surface waters, defining the significant management issues, such as pollution with biogenic substances, organic and chemical pollution, pressure from water intake and climate pressure. These problems solutions require both science-based approaches and specific target measures definitions to improve the water resources status and the level of their management.

This paper aims to present the land quality and productivity of the administrative territorial unit of Murfatlar, Constanța County, located in south-east of Romania, an area well known for its vineyards, while used for specific purposes, such as agricultural destinations. The assessment is based on the analyses of climate (temperature and precipitation), soil (type, texture, reaction, gleization, presence of microforms and water), relief (slope), as well as other aspects of land, and their interpretation in order to determine the fertility of the site and its suitability for cultures (such as wheat, canola, corn, etc.). For the results and discussions phase, the soil bonitation note was calculated and a qualitative classification map was made to illustrate the potential productivity level. However, due to the fact that the soil evaluation is developing under both natural and human-caused environmental changes, the bonitation note needs to be revised often.

The paper aims to assess the air pollution level using one mobile low-cost measurement system versus in situ sensing data from local air quality network stations. The measurements were performed during the winter of 2022 on the main streets of Galați city, one of the largest cities in Romania. The main purpose of the measurements is to use mobile measurements to capture the spatial and temporal distribution of important air pollutants such as NO2+O3, CO, SO2, and PM10 in large urban areas. For this study used a mobile air quality monitoring system Sniffer 4Dv1 to record spatial and temporal data on air pollutants on the street of Galati City. The data sets from local RNAQMN (Romanian National Air Quality Monitoring Network) are compared with Sniffer 4Dv1 data to infer various limitations for each of the two data sets.

Microplastics are considered emerging pollutants of growing concern due to their ubiquitous presence and toxic potential in the aquatic ecosystem. However, there are few studies assessing the occurrence of microplastics in freshwaters, most articles are focused rather on the marine environment. Due to the lack of standardized protocols for separating and analyzing microplastics, different methods are described in the literature data. In this paper, FT-IR spectrometry coupled with microscopy (micro-FT-IR) was applied to identify the presence of microplastics in the Predeltaic sector of the Danube River. Based on the morphological classification, the microplastics collected were fragments, films, and fibers. The results of micro-FT-IR analysis confirmed the majority presence of polyethylene and polypropylene-based microplastic particles in water.

The current research presents the way to obtain direct georeferencing of photogrammetric imagery and to obtain rigorously georeferenced orthophoto plans without using ground control points. The direct georeferencing procedure is studied in Romania's atypical coordinate systems (planimetric system based on an ellipsoid different than GRS80 and a vertical system of normal elevations, different than the ellipsoidal elevations used in GNSS technology), but it can also be applied to other systems of coordinates. To generate superior photogrammetric products, an innovative orthorectification methodology based on LIDAR data acquired simultaneously with photogrammetric images is presented. LIDAR data is also acquired by a direct georeferencing procedure and transformed with high precision using an application designed for this purpose. Therefore, a much faster way to generate orthophoto plans is presented, with lower production costs, without a substantial loss of the positional quality of the final product. Finally, there is presented the first stereo restitution project in Romania using small size images, acquired with a UAV system by direct georeferencing. The focus on the atypical case of Romania underlines the innovative features of this research.

The characterisation and knowledge of the Gurghiu drainage basin represents a realistic analysis of the current state of the drainage basin. This analysis led to the obtaining of information on morphometric parameters specific to the drainage basin and the Orşova, Fâncel and Sirod sub-drainage basins; the current state, together with the effects and efficiency of torrent correction works in these sub-drainage basins and the knowledge of the grain size of the alluviums accumulated behind the hydrotechnical works. To analyse the profitability of the hydrological management work in the sub-drainage basin Fâncel, a series of specific indicators were used: specific investment, duration of the recovery of the investment, updated net value, internal rate of return and profitability index. The total amount of alluvium retained in the valleys of the Gurghiu hydrographic basin is 24,960.3 m3, with direct retention accounting for 6,774.55 m3 and consolidation for 8,185.8 m3. The analysis reveals that the costs associated with extracting torrential alluvium would have been roughly 1,859.55 thousand lei. Recommendations are to urgently restore essential repairs to damaged, broken, or detached parts of the work, to cover infiltrations and cracks and to complete masonry in places affected by degradations.

The paper aims to analyze the impact of logging activity on residual trees from logging yards from southwest Romania, located in plain, hill and mountain area and covered with a large variety of silvicultural works-first-intervention cuttings, preparatory and seed-cutting (shelterwood systems or selection systems), cuttings to increase light availability for regeneration (shelterwood systems), final cuttings (shelterwood systems). The impact of logging activity on the residual trees was analyzed based on the data obtained from the measurements made at the end of the vegetation season of 2019 and the beginning of the vegetation season of 2020. Based on the data obtained, the total number of tree damages in the variants studied on relief forms, the relationship between the number of tree damages and different stand characteristics, and the damages distribution by their types in the studied variants, were analyzed. Trees damage evaluation was done by determining damage indexes calculated as a ratio between the volume of damages found and the volume of damaged trees. The most important conclusions have been discussed in the context of other researches in the field.

The sessile oak stands within the seed reservation that were affected by the extreme weather phenomena (windthrown and windsnapped trees) on the 17th of September 2017, from the forest fund of the U.P. VII Văratec, the Forest District Sudrigiu, County Forest Administration Bihor, presents a relatively low ecosystem stability, considering the impact suffered. After the identification of the sessile oak stands affected (by extreme weather phenomena), the assessment of the affected wood material was carried out and implicitly, its extraction and superior valorization. The necessary works, proposed for the ecological rehabilitation of the sessile oak stands that have been examined and studied, take into account their actual state, the regulations of the forestry management plan for the current decade, the provisions of the technical norms in force at the date of implementation of the study, and last but not least, the necessary logistical and financial possibilities. Surfaces from which the wood material was extracted, will be delimited in separate management units, which will regenerate naturally from the seed coming from the remaining stands, thus preserving their provenance in-situ.
