PC2 MODSPA-NUTRITOX se încadrează în programul de cercetare pe termen lung inițiat în 2007 de UB, ICPA, IBB și ISMMA Prin PC2 a avut loc extinderea programului către procese de interfață relevante pentru evapotranspirație Mobilizarea partenerilor s-a făcut prin formularea unor ținte mai ambițioase decât cele contractate Au fost realizate toate livr...
Article
Full-text available
The paper aims a review of the water quality monitoring and evaluation studies conducted at National R&D Institute for Industrial Ecology over the last ten years, at the level of aquatic ecosystem complexes in the Danube Delta. The paper will include a broad compendium of data including: a data bank of abiotic variables which control the structure...
Article
Full-text available
Occurrence and fate of 18 pharmaceuticals belonging to various therapeutic classes were investigated in the aqueous phase of river water at 16 sampling locations along the Romanian side of the Danube and its three tributaries (Jiu, Olt, Arges). Analyses were performed by solid-phase extraction (SPE) followed by liquid chromatography-tandem mass spe...
Article
Full-text available
This paper presents a systemic assessment for abiotic components of the complex ecosystems in the year 2014; the investigated area is the Danube River from Bazias to Calarasi and its tributaries from Southern Romania rivers Jiu, Olt and Arges. A sampling and monitoring program was performed for representative control sections, whose geographic loca...
Article
Non-compliant landfills generated emissions over a long periods of time that may affect the quality of the environmental components in the vicinity. The conceptual model and the investigation model of the landfill analysed as a case study contain elements that permitted us to establish the environmental vulnerabilities and quantify the associated r...
Article
Full-text available
Ecological risk assessment is required by the European norms to predict or evaluate the effects of chemicals, which are discharged into the receiving 'environment'. Usually the aquatic risk involves two major components: occurrence and hazard effects. In order to estimate the predicted exposure concentrations of chemicals in the water (PEC aquatic)...
Article
The aim of this study is to assess freshwater sediment in terms of biological and preliminary toxicological control linked to a series of variables along the Danube River and Danube Delta systems. The research is focused on eight points of the Romanian sector in the summer to autumn of 2012. Results show a high concentration of metals, pesticides,...
Conference Paper
Full-text available
A preliminary acute evaluation of toxicity in Danube River-Danube Delta Romanian sector (1075 – 0 km) was proposed including surface-water and sediment. The conventional classification of natural waters is based primarily on chemical and physical parameters. Recently the hazard classification have include the use of selected microbiotests based on...
Conference Paper
Full-text available
Over the last 50 years humans have converted the export of fluvial materials which induced significant changes in biology, chemistry and morphology of the aquatic systems. The study presents the long-term changes induced on biotic communities alongside chemical parameters in Danube Delta systems after industrialization period in the context of comp...
Chapter
The main objective of this paper is to highlight the dynamics of biotic community in terms of spatial and temporal relationship. The biotic community dynamics in St. Gheorghe Branch were discussed based on existing data and the results of our own research during 2003–2009. Surface water and sediment samples have been collected monthly from two cont...
Article
The effects of global changes on the water quality of the Danube delta (St. Gheorghe branch) were investigated using the causal framework DPSIR, model used for describing the interactions between society and the environment adopted by the European Environment Agency (EEA): driving forces, pressures, states, impacts and responses. It is known that i...
Article
Regulation (EC ) No 1907/2006 - Registration, Evaluation and Authorisation of Chemicals (REACH) is the most important European legislative regulation concerning chemicals and became applicable in Romania since June 2008. In the period 2008-2011, chemicals manufactures/importers and also eco-toxicological laboratories have made great efforts to comp...
Article
The spatial and temporal variation affects the processes and patterns of the environment, particularly in structured systems such as river networks. Chlorophyll is bound within the living cells of algae and other phytoplankton found in surface water. The aim of the study was to describe the seasonal and spatial distribution of surface chlorophyll a...
Chapter
Full-text available
The main objective of this paper is to provide data on the Danube River Delta Biosphere (Romania) aquatic ecosystem quality and Vardar – Axios River Valley (FYR Macedonia – Greece) on comparison basis from on the long-term analytical investigation for specific indicators. In particular this paper is focused on the quality assessment of surface wate...
Article
Full-text available
The purpose of this paper is to show the results of the investigation of the environmental components quality (surface water, groundwater and sediments) in the winter - spring 2008 campaigns. The systemic characterisation of the physicochemical and biological environment is realised by development of investigation program of the water body represen...
Article
The dynamic equilibrium of the aquatic ecosystems is accomplished because of the connections between the species and the environmental conditions and also because of the mutual connections between the existing populations. From this point of view, the study of biotic - phytoplankton, zooplankton and/or benthonic components - from the position of th...
