Morphological changes analysis using 3D bathymetric surveys in Chilia Branch - Bystroe Channel bifurcation area

2023 , Georgeta Tudor , György Deák , Marius Raischi , Miruna Arsene , Elena Holban , Norazian Mohamed Noor , Roshazita Che Amat

The Bystroe Channel project with transboundary environmental impact in the Danube Delta, area of great ecological significance that has already a strong anthropic footprint, requires close monitoring of water quality parameters in order to determine their tendencies and their impact on the ecosystem components. Riverbed bathymetry surveys using multibeam echo-sounders are of high interest due to the data resolution and coverage capabilities that surpass the single-beam methods. Two riverbed elevation datasets, recorded in consecutive years, have been used to carry out morphological comparative analysis for the area where Chilia branch bifurcates in Bystroe Channel and Old Stambul. The analysis has been performed both on the bathymetry grids as a whole and on 3 longitudinal and 9 transversal river sections, the morphological changes values being in majority included in [-0.5 m;+0.5 m], with a minimum of -2.4 m and a maximum of 2.2 m, showing the bifurcation influence on the erosion/deposition processes results.

Assessment of antibiotics from natural water resources and the potential ecological risk associated with their presence in aquatic ecosystems for developing advanced technologies for removal of antibiotic

Aquatic ecosystems provide many services for society including water for drinking, irrigation, and recreational activities. Emergent contaminants such as antibiotics that are present mainly in urban wastewater have a substantial impact on environment and human health, such as: Potential genotoxic effects, disruption of aquatic ecosystems and development of antibiotic resistance. The main objective of this paper is to develop an advanced analytical method for identifying emergent pollutants within the antibiotic category by using high performance SPE-online-UHPLC-MS/MS techniques from different aqueous matrices, in order to develop technologies to remove them from wastewater. The ecological risk index (RI) associated with the presence of antibiotics in aquatic ecosystems was also calculated for potential ecological risk assessment, using the ratio between the measured concentration (MC) of antibiotics detected in surface water and predicted no-effect concentration (PNEC) values.

Evaluation of the ecological risk and the development of antimicrobial resistance due to the presence of the Macrolide antibiotics Azithromycin and Clarithromycin in Romanian aquatic environment

The presence of antibiotics in the aquatic environment can result in the emergence of antibiotic-resistant pathogens. In this paper, our aim was to identify, quantify and distribute macrolide antibiotics in the aquatic environment in the river basins of Arges-Vedea, Buzau-Ialomita and Dobrogea-Litoral and of the Danube River. In the Arges-Vedea river basin area, clarithromycin was detected most frequently, i.e. 58.62%, in the Buzau-Ialomita river basin area with a frequency of 92.31% azithromycin was detected, and in the Dobrogea - Litoral river basin area clarithromycin was detected with a frequency of 35.48%. The highest concentration of azithromycin, 559 ng/L and of clarithromycin, 502 ng/L was recorded in the Buzau-Ialomita river basin. The ecotoxicological RQecotox risk was also estimated, as well as the risk of developing antibiotic resistance of RQAMR pathogens, by the ratio of Measured Environmental Concentration (MEC) and Predicted No Effect Concentrations (PNEC). The study also aimed to investigate the prevalence of antibiotic resistance in potentially pathogenic bacteria isolated from aquatic environments. Thus, for β-lactam antibiotics, E. coli strains isolated from the Danube River exhibited a very high level of resistance to ampicillin (51%) and high level to azithromycin (43%), cefazolin (38%), amoxicillin+clavulanic acid (36%) and cefoxitin (26%). Low and respectively, low level resistance was noticed for aztreonam (6%) and imipenem (4%).

The effects of climate change are becoming more intense in the last decades. Moreover, according to many official reports, climate changes are directly affecting ecosystems and their services. To assess the impact of climate change on ecosystems, various methods are being used in order to identify changes and interactions with other pressures such as degradation or fragmentation. Adaptation and mitigation measures on the effects of climate change generally include land use changes and land use practices. In order to assess the effectiveness of adaptation and mitigation measures, the services provided by ecosystems and their status are monitored. The paper presents the general framework for evaluating adaptation and mitigation measures and it is based on research from reference works that generally recommend how to evaluate adaptation and mitigation measures. A local adaptation of the mitigation and adaptation framework is presented, by identifying methods for assessing state indicators and ecosystem services. Depending on the availability and accuracy of the data, are proposed methods structured on different levels of detail such as: statistical data, field measurements, modeling software. The application of the proposed methods was verified in a case study: Divici Pojejena wetland, for which detailed methods of assessing the state and services of ecosystems were used.

Assessing the self-healings properties of nano -Ca(OH)â‚‚ - TiOâ‚‚ - ZnO materials used in monuments conservation works

2023 , Moncea Mihaela-Andreea , Deak Gyogy , Gheorghe (Dumitru) Florina-Diana , Norazian Mohamed Noor , Nur Liza Rahim

Consolidates based on Ca(OH)â‚‚ have been prepared as macro- and/or nanoparticles dispersed in different alcohols, regardless of the precursor nature. Their efficiency is related to the small dimensions of the particles and the dispersion media, which allows their penetration into the deteriorated material substrates, as well as to an increased reactivity towards COâ‚‚. Besides the consolidating effect there is a strong need for the newly developed materials to also tackle other properties like self cleaning and antimicrobial activity, especially with regards to white monuments. In this context the present work highlights the effect of treating with stable alcoholic suspension containing nano - Ca(OH)â‚‚ - TiOâ‚‚ - ZnO the physical support models consisting of mortar cubic samples from hydraulic / aerial lime, a commonly used materials in consolidation works.
