TEAM IN 2007-2011 PERIOD

Specilists of DDNIRD constantly involved in activities of the Chemesty Laboratory (as main research team) are:

Scientific researchers gr.III

Note: support staff includes four technicians.


The Chemistry Laboratory of Danube Delta National Institute for Research and Development was set up in the early ‘70s and it focused on specific research projects monitoring of surface water and sediments of the Danube Delta Biosphere Reserve (DDBR).
The first stage in infrastructure development of DDNI Chemistry Laboratory was in 1996 when in the GEF / World Bank funded project for the Biodiversity of the Danube Delta (1995 - 2000) the Chemistry Laboratory was equipped with high performance equipment: UVVIS Lambda 10 Spectrometer, Solid Phase Extractor SPE and a Varian AA 100 Spectrometer.
Organized by RIZA Institute in the Netherlands the laboratory specialists participated in some training courses in the Delwett Centre of Excellence Project - october 2002 – in inorganic analysis (heavy metals) and in “Working Visit Centre of Excellence’’ RIZA Institute, the Netherlands - october 2003 - organic analysis GC/MS training course.
An important stage in the Chemistry Laboratory infrastructure development was in 2005 and 2006 by participating in two competitions of the Centre of Excellence Program (CEEX), Module IV, when high tech equipment acquired (Microwave oven Anton Paar, Inductively Coupled Plasma Mass Spectrometer ICP MS Elan DRCe, Atomic  absorption with cold vapor FIAS 400, Accelerated Solvent Extractor ASE 100 Dionex, Gas Chromatographer with Electron Capture Detector GS/ECD Clarus 600) allowed the increase of chemical analysis quality also the extension of analyzed indicators field in the scientific research projects and the possibility of laboratory involvement in national and international projects.

In 2006 the Chemistry Laboratory of Danube Delta National Institute for Research and Development has been accredited according with SR EN ISO/ CEI 17025: 2005 by the Romanian Accreditation Association (RENAR) to 27 indicators. More indicators were accredited in 2008 reaching in 2010 up to 41 indicators  accredited by the Romanian Accreditation Association (RENAR) with the Certificate of Accreditation nr. LI 434 available until 2014.
The Chemistry Laboratory is accredited for all types of determinations: determination by molecular absorption spectrometric methods, determination by atomic absorption with cold vapors spectrometric methods, determination by mass spectrometry with inductively coupled plasma, determination by gravimetric methods, determination by volumetric methods, determination by electrochemical methods, determination by gas chromatography.


In the last 4 years the team-members of the laboratory were involved in 13 projects dealing with water quality assessment of surface water, groundwater and environmental objectives.

The team-members contributed:
- to the improvement of physicochemimcal analytical quality control practices in DDNIRD laboratory
- to the development of the infrastructure for evaluation and certification of conformity for ecological and chemical state in the Danube Delta according with Water Framework Directive
- to the development of the monitoring programme in Danube Delta Biosphere Reserve in compliance with the requirements of Water Framework Directive
- to the development of the monitoring networks in Danube Delta Biosphere Reserve
- to the improvment of the water quality classification schemes of the Danube Delta Biosphere Reserve
- with background information to the evaluation of the ecological status of the surface water of the Danube Delta Biosphere Reserve using the spatiotemporal anlysis of the main physical and chemical factors which are important in management decisions for sustainable resources management in Danube Delta Biosphere Reserve
- to the analysed of spatiotemporal variability of the stable isotopes content along the Romanian Danube Basin
- to the analysed of the organic and inorganic micro-pollutants concentration in the food chain
- to the evaluation and modeling of the hyporheic area by the development of the high resolution method


The Chemistry Laboratory provide assistance for several team member to develop their PhD or MSc theses, as follows:

Dr. chemist Liliana TEODOROF -
awarded in 2009 with the thesis: “The influence of physical and chemical factors on the micro pollutants distribution in deltaic ecosystems”
Dr. eng. Cristina NASTASE - awarded in 2010 with the thesis: “The environmental factors impact on the heavy metals presence in deltaic ecosystems”
2010 - Daniela SECELEANU’s MSc thesis: “Studies and researches on the monitoring of surface water quality from DDBR” – carried out at „ Tehnical University ” – Cluj Napoca, Faculty of Engineering of Materials and Environment
2011 - Adrian BURADA – PhD student – Lower Danube University of Galaţi; “ University of Science and Environmental” Thesis – “Monitoring of environmental factors in deltaic ecosystems”
