1. INTRODUCTION
This report presents the final report of the work performed by the Romania team from National
Research and Development Institute for Environmental Protection - ICIM Bucharest, as part of
the consortium designated for accomplishment of "Iron Gate Sediments Evaluation" project,
within the UNDP/GEF Danube Regional Project - the group of small contracts for services.

2. OBJECTIVES
According to TORs, the main general objective of the project is to assess the sediment quality in
the Iron Gates Reservoir and based on those results to prepare initial recommendations for
future protection of the Danube River and Black Sea.
2.1. Specific objectives
Out of the specific objectives outlined in the TORs, the following ones have been dealt with in
the previous stage of the project:
2.1.1. Collecting and reviewing the existing data and information on present
situation
As it was specified in the Inception Report and further in the Technical Report, the national
team collected existing and available data on sediment quality from the sites located in the Iron
Gate Reservoir area. The sources of sediment quality data (as well as essential issues
concerning the Quality Control/Quality Assurance, where available) are below briefly presented.
2.1.1.1. Description of existing data sources
EROS 2000 PROJECT ­ for data from year 1995
This study was the output of a research contract between the European Community (PHARE
Programme) and the Romanian Centre of Marine Geology and Geo-Ecology regarding the
eutrophication and contamination state of the Danube River.
During the EROS Danube River Cruise (June 1995) bottom sediments were collected by grabs
and corers and the samples were analysed for grain size distribution, chemistry (major
compounds, heavy metals) and mineralogy (clay and heavy minerals).
The samples from the core were collected for measuring the variations in heavy metals and
oxides contents.
The Technical Report on Iron Gates contains also some information on the grain size distribution
analyses.

ECOTOXICOLOGICAL STUDY CONCERNING THE DANUBE RIVER POLLUTION
RESULTING FROM THE EVENTS OF YUGOSLAVIA - for data from year 1999
This study consisted of a chemical and biological survey along the border between Romania and
FRY (as it was in that time) in order to assess the impact produced by relevant persistent
pollutants potentially released during the conflict in Yugoslavia, on the Danube River's
ecosystems.
As far as concerns sediment quality investigation, samples were taken in July 1999, from 9
sections along the Danube (Romanian and Yugoslavian border) between rkm 1071 - 834;
sampling sites from each section were at various distances from left bank and on the main
stream.

TRANS-NATIONAL MONITORING NETWORK - NATIONAL DATA BASE for data from
2000
As it was agreed within the former MLIM ­ Expert Group of ICPDR, for this monitoring
programme, sediment samples are taken and analysed according to Standard Operating
Procedures (SOPs) applied within the TNMN. These SOPs are applied as well in all TNMN
National and Regional Reference Laboratories from the Danubian countries.
JOINT DANUBE SURVEY (JDS) ­ for data from 2001
Sediment samples were taken from the left and right banks of the river either with a sampling
net or with the grab sampler in 98 stations within the whole catchment area out of which 13
stations were in the Iron Gate reservoir. Sediment sampling was followed by on-board grain size
fractionation with wet sieving for obtaining the less-than 63 µm fraction for laboratory analysis.
Determination of heavy metals
For heavy metals analysis sediment samples were pretreated according to ISO/DIS 11464:1992
­ "Soil Quality. Pre-treatment of samples for physico - chemical analyses".
Determination of aluminium, cadmium, chromium, copper, iron, lead, nickel, manganese and
zinc in the extracts was carried out by ICP-AES (Perkin Elmer OPTIMA 2000 DV) according to
ISO 11885. Arsenic and mercury were determined by flow injection-graphite furnace-AAS using
the hydride/cold vapour principle (Perkin Elmer 4100 ZL with FIAS 200).
Determination of organic pollutants
Petroleum hydrocarbons were analysed during JDS by using different analytical methods,
including GC-FID for total petroleum hydrocarbons (TPH), TPH was determined by using UV
absorption and fluorescence procedures, as well as GC/MS analysis of Polycyclic Aromatic
Hydrocarbons (PAHs).
The JDS list of determinants included the following:
>
five organochlorine compounds (Lindane, Hexachlorobenzene, Hexachlorobutadiene,
Pentachlorobenzene, pp'-DDT);
>
seven polychlorinated biphenyls (PCB 25, 52, 101, 118, 153, 138, 180).
>
Polycyclic Aromatic Hydrocarbons (PAHs)
>
Nonylphenol (4-para-nonylphenol) and Octylphenol (para-tert-octylphenol)
>
Organotin compounds (tributyltin cation ­ TBT).
AQUATERRA INTEGRATED PROJECT ­ for data from 2004
The Aquaterra Danube Survey (August ­ September 2004) provided additional results and data
concerning the concentration of selected chemical compounds in sediments and suspended
matters.
Sampling sites were selected out from the sites investigated during the Joint Danube Survey
and were selected a number of 30 stations on the Danube River.
Sediment samples were taken from both left and right banks of the river, using a sampling net
and a grab sampler. Sediment sampling was followed by on-board grain size fractionation with
wet sieving for obtaining the less-than 63 µm fraction for laboratory analysis of selected
determinants.
Sediment samples were sampled and handled according to the appropriate Standard Operations
Procedures and Standards Methods, as it follows:
>
ISO 5667-3:1985: Preservation and handling of samples;
>
ISO 5667-6:1990: Sampling of rivers and streams;

>
ISO 5667-15:1991: Preservation and handling of sludge and sediment samples;
>
ISO 5667-17:1991: Guidance on sampling of suspended matters.
With each series of samples were analysed certified reference materials. In total, 5 certified
reference materials (1640 Trace Elements in Natural Water (NIST, USA); TMDA ­ 54.3 a
fortified calibration standard for trace elements (NWRI, Canada); Sewage sludge BCR 144 R
(IRMM, Belgium); Soil LGC 6138 (GB); Sediment GBW 067306 ­ China) were used in order to
assure quality control of measurements.
Following appropriate dilution to fit the calibration range, the elements were determined in
digests of suspended matters, bottom sediments and certified reference materials as follows:
>
Cd, Cu, Fe, Mn, Ni, Pb and Zn by flame atomic absorption spectroscopy according to ISO
8288/1986 (Cd, Cu, Ni, Pb and Zn) and Cr according to EPA/600/4-79/020, 1983;
>
As by hydride generation technique of atomic absorption spectroscopy ;
>
Hg by cold vapour technique of atomic fluorescence spectroscopy according to EN
13506/2001;
>
Al by inductively coupled plasma mass spectroscopy according to ISO 17294-2/2003.
2.1.1.2. Considerations on existing data and information
>

2.1.2. Assessment and reviewing the existing data and information
Pollutants in sediment constitute a major factor in the way in which ecological or chemical water
status is influenced. Assessment of sediment quality is not always an easy task to fulfil given
the fact that there is not one "best" method available. The key issue in quality sediment
evaluation is the "crossing approach": certain pollutants negatively impact the ecological
status by their hazardous character. On the other hand, the real of contaminants is mainly
determined by their biovailability. Sometimes, strongly and irreversibly sediment-bound
sediment pollutants are hazardous but their risk is negligible. Moreover, even if a sediment
contaminant becomes available by various factors ­ bioturbation or a flooding event ­ still there
is not a direct relationship with impact to chemical or ecological status. Therefore, it is rather
difficult to estimate whether or not a certain level of pollution will adversely influence chemical
or ecological water quality.

Expert judgment in assessment of sediment quality provides a simultaneous application of three
tailor-made solutions, commonly referred to as the Triad-approach:
>
Chemical analysis ­ in order to determine concentrations of selected, hazardous

2.1.2.1. Technical approach in assessing the Iron Gates sediment quality
The technical report took into account the "chemical analysis" method by groups of
determinands and depending on the existing pre-defined standards and guidelines and based on
a number of Sediment Quality Standards and Guidelines the assessment was done for the types
of pollutants identified also in the previous projects. Based on the data processing done and the
discussions of the results it was concluded a certain level of pollution associated to sediments
and based on the gaps identified as well the new data necessary for better assessment were
recommended as part of the field trip sampling campaign planned and executed in September.
For the technical report, four sets of values were used, both as national quality standards and
international quality guidelines ­ the Romanian, the Canadian, the Dutch and the North-
American guidelines (EPA) - briefly described below:

National (Romanian) Environmental Quality Standards are legislated by Order 161/2006 for
Surface Water Quality Classification for establishing the Ecological Status of Water Bodies. Four
groups of determinands, containing a total number of 44 compounds, are selected for chemical
investigation of sediments (fraction less than 63 µm). For each contaminant one value is set as
Quality Standard.

Canadian Sediment Quality Guidelines are numerical concentrations or narrative statements
that are set with the intention to protect all forms of aquatic life and all aspects of their aquatic
life cycles during an indefinite period of exposure to substances associated with bed sediments.
The levels on which the sediment evaluation has been carried out were:
>
The Threshold Effect Level (TEL) - also the same as Interim Sediment Quality Guidelines
ISQG - represents the concentration below which adverse biological effects are expected
to occur rarely;
ICIM / POPESCU, HAMCHEVICI

Final Report_ICIM
page 15
>
The Probable Effect Level (PEL) that defines the level above which adverse effects are
expected to occur frequently; unless otherwise specified, SQGs refer to the total
concentration of the substance in surface sediments (i.e., the upper few centimeters) on
a dry weight basis (e.g., mg/kg or µg/kg dry weight).
By deriving TEL and PEL, three ranges of chemical concentrations are consistently defined:
>
the minimal effect range (values below TEL) within which adverse effects rarely
occur;
>
the possible effect range (values between TEL and PEL) within which adverse effects
occasionally occur;
>
the probable effect range (values above PEL) within which adverse effects frequently
occur.
EPA Sediment Quality Guidelines consist of two sets of values:
>
Sediment quality guidelines that reflect threshold effect concentration (TEC); is the
level below which harmful effects are unlikely to be observed
>
Sediment quality guidelines that reflect probable effect concentration (PEC); is the
level above which harmful effects are likely to be observed
Dutch approach for sediment quality: The Dutch Environmental Quality Objectives are specified
in terms of a target value that is set at a negligible concentration, usually 1/100th of the
maximum permissible concentration. If the negligible level is lower than the background
concentration, the target value is set to that level. Limit values were only set for the upper
sediment layer, in direct contact with water.
2.1.2.2. Main conclusions drawn from the Technical Report
Based on the present evaluation of results regarding sediments quality in the Iron Gates area,
the following conclusions can be drawn:
>
The existing sources of raw data were heterogeneous as concerns the order of
magnitude of pollutants concentration.
>
The reliability of data could not be consistently proved in the case of data from 1999.
Therefore, compliance of these data with various Sediment Quality Guidelines has a
small degree of correlation with the compliance of data from years 2000s and after.
>
Next sampling step should take into account core sediments samples in the studied
stretch in order to evaluate historic contamination and to compare the results with
previous investigations.
>
The current data should be further correlated with previous data concerning certain
target pollutants existing in suspended solids phase (data from 2001 and 2004).
>
There is a strong need for further investigations especially in the case of Priority
Substances recommended within the Water Framework Directive or other xenobiotics,
which are included in the Lists of Hazardous and Dangerous Hazardous Substances.
>
A more comprehensive approach of the assessment of sediment quality should be
adopted and applied in terms of looking at actual risks or impact of the contamination
rather than checking whether quality standards and guidelines are exceeded and in
doing this the eco-toxicological tests can be applied.

2.2. Specific objectives dealt with in the present stage
According with the TORs project, the last phase's specific objectives are the following:
>
Undertaking sampling and analysis as agreed by the overall project team
>
Proposing further monitoring programmes.
2.2.1. Description of the field trip and sampling activities performed
Taking into account the results from the Technical Report and in order to keep the data
continuity, it was agreed that the following quality determinands would be analysed in sediment
samples collected during the field campaign: organic nitrogen and total phosphorous, heavy
metals (Mercury, Cadmium, Lead, Nickel, Chromium, Arsenic, Copper, Zinc), organic micro-
pollutants (DDT, Lindane, Aldrin, Endrin, Dieldrin), Nonylphenol, Octylphenol, Pentachlorphenol,
Di(2-ethylhexyl)phthalate, PAHs, PCBs), Extractable Petroleum Hydrocarbons and Particle Size
Distribution.
The surveyed stretch was comprised between Upstream Velika Morava (river km 1107) and
Mala Vrbica / Simian (river km 924). The sampling sites as well as the type of sediment samples
from the each sampling site are presented in the Table 4.

2.2.1.1. Technical conditions of the sediment sampling
Grab sediment samples were taken using an Ekman dredge from both left and right banks of
the river, at each sampling site, except for site no 8 (Dubova, river km 971 where no sediment
was found on the left side. Grab sampling was followed by wet sieving in order to obtain the
less-than 63 µm fraction for chemical analysis in the lab. Core sampling was carried out using
an Eijkelkamp core sampler and samples were taken from the right side at river km 1077 (Stara
Palanka ­ Ram) and at rkm 924 (Vrbica / Simijan) and from the both sides of the river at
sampling sites no 7 and 9 (Donji Milanovac, river km 991 and Orsova, river km 956
respectively. The core sample was then divided into 10 centimetres slices for further analysis in
the lab ­ see Fig. 1.

2.2.1.2. Sample analysis
According to the proposed and agreed list, the following determinands were analysed by ICIM:
Total Phosphorus, Organic Nitrogen, Heavy Metals (Mercury, Cadmium, Lead, Nickel, Chromium,
Arsenic, Copper, Zinc), Extractable Petroleum Hydrocarbons, Organo-chlorine Pesticides (DDT,
Lindane, Aldrin, Endrin, Dieldrin), Nonylphenol, Octylphenol, PAHs and selected PCBs.
Pentachlorphenol and Di(2-ethylhexyl)phthalate were not analysed because of the lack of the
suitable equipment. In Table 6 a short description of the samples preparation and the analytical
methods that were used in the ICIM's laboratory is shown:

The results of the performed analysis are presented in Annex 1 of this final report.
2.2.1.3. Results evaluation
The evaluation of the sediment quality based on both pre-existing data and information and on
data emerged from the sampling campaign performed in September 2006 is going to be done
based on the final agreed data set reported by the three laboratories involved.

In accordance with the agreement made between the DRP leader, the International Expert Co-
coordinator (VITUKI) and the working teams of the two countries involved (Serbia and
Romania), the final processing of the newly produced data and the already collected data
(including the final interpretation of the results) will be done by VITUKI.
2.2.2. Proposing further monitoring programmes
Many previous cases showed that sediment investigations were designed to be descriptive
studies presenting temporal and spatial distributions of contaminants. This approach - also
applied in some above mentioned studies related to the Iron Gates sediment evaluation ­ was
mainly focused on assessing the compliance of the determined concentrations of selected
contaminants with the pre-defined quality standards (if available). Once the exceedence of a
certain quality standard is checked, this assessment method has to be completed by taking into
consideration the actual risk and/or impact of contaminated sediment given the fact that
contaminants in sediment may strongly impact the ecological or chemical water quality status.
Hence, a further monitoring programme for the Iron Gates reservoir area shall continue with:
>
Monitoring of WFD priority hazardous substances that have a strong preference to stick
to sediment (such as hydrophobic organic compounds);
>
Given the WFD objective related to "non-deterioration" sediment quality, monitoring of
the above mentioned substances should be applied both in terms of spatial and trend
monitoring. Spatial monitoring is necessary in order to evaluate the extent in which a
certain contaminant is spread over a studied area and probably to detect its source
based on available emission data. Trend monitoring should be carried out in order to
evaluate the temporal pattern over a long time period. This type of programme shall
include also the study of deeper sediment layers (core sediment samples at the same
spots as the ones from the previous studies) in order to reflect the historic
contamination;
>
Along the Iron Gates area, the spatial monitoring shall include at least the sampling
sites from the studies that have been taken into account in this evaluation (data from
2001 and 2004) and that have been included in the list of the sampling campaign from
September 2006;
>
The present monitoring programme (hazard assessment method as the first circle of the
Triad-approach) might be complementary followed by the evaluation the toxic effect of
sediment on organisms using bioassays and by impact assessment using field inventory
(assessment of taxonomic composition and abundance of benthic invertebrate fauna).
>
The frequency of the Iron Gates sediment monitoring should be established based on a
common agreement among the stakeholders involved and based on technical criteria
such as: present information on sediment quality compliance with EQSs, sedimentation
rate and existing or further identification of new anthropogenic pressures.
