GES description |
In order to estimate GES with respect to the first criterion of this descriptor (Concentrations of contaminants), we can conclude that the measured concentrations of priority substances in seawater (33 +8) show that good environmental status is achieved, because only 3 of 24 samples exceeded the criteria, but insufficient number of measurements (only two sampling campaigns) do not give a reliable assessment of the condition of priority substances. Altogether it can be concluded that the GES has not been achieved for all measured parameters, however, it should be taken into account that the most of the locations where the samples were taken from were exposed to strong anthropogenic influence, so it is questionable whether this assessment is relevant for the whole Croatia?s Adriatic coast and it should be considered to be only partially reliable. The assessment of GES in relation to the second criteria of this descriptor (Effects of contaminants) is that GES is reached. Due to the lack of data on the effects of significant acute pollution events, considering this indicator GES assessment is not possible. |
The concentrations of priority substances in seawater, measured 2010 in the potentially endangered water bodies, (13 of 16 examined stations) were mostly within the set Standards of environmental quality, except in the two water bodies where elevated concentrations of C10-13 chloroalkanes or TBT were found. Results of measurements of priority substances at 8 potentially threatened coastal areas during 2014 indicate good chemical status at 7 stations examined, while one indicated the elevated concentration of lead. These preliminary results indicate that the concentrations of most of priority substances in seawater are not elevated, but based on only two measurements it is difficult to make a definitive conclusion about the state of pollution by these substances. Monitored metals in shellfish, during the last 10 years show a growing trend for Pb, Hg, and Zn, while Cd and Cu showed no significant changes. Concentrations of metals in sediment were monitored at 12 locations. As well as for shellfish, concentrations of all metals in the sediment were significantly elevated in harbors, or area exposed to industrial pollution. Average concentrations of metals in sediment showed no significant temporal trends, primarily because of the way of sediment sampling that does not allow temporal resolution on a scale of 10. All measured concentrations of organotin compounds in shellfish significantly exceed BAC according to OSPAR, especially in the harbors where marine traffic is enhanced. Reduction of TBT in 2011 indicates decreased input of TBT in the marine environment. At all locations, concentrations of PCBs in shellfish were significantly higher than BAC values. Trends of average concentrations show slight decline, but it is obvious that the PCB contamination is still notable. Mean concentrations of the sum of 7 congeners in sediment were measured at 6 locations in the period of 2006-2011, showing that the concentrations are the highest at the location OT10 in the Kastela Bay, similar to that of shellfish. All average concentrations of chlorinated pesticides (DDE (p, p*)) in shellfish are higher than the BAC values, but the trend of the pressure is significantly decreasing; similar situation is recorded in sediment. The highest concentrations are at the locations that are significantly exposed to anthropogenic impacts. Average lindane concentrations in shellfish are all significantly lower than the BAC values and demonstrating their downward trend, while lindane was not discovered in the sediment. Radionuclides in seawater and sediment: Regular measurements of activity concentration of fissile radionuclides 90Sr i 137Cs in surface waters at 8 coastal stations, as well as 137Cs in sediment at 3 open sea stations, point to low activity concentration during the last 10 years. |
Good environmental status has not been reached for some metals (especially Hg and Pb) and PCB. Data for concentrations of priority substances and synthetic contaminants in coastal waters are insufficient. There are not enough data on the reference values for the Adriatic, so that the criteria of OSPAR were used. Most of the sites with available data are exposed to significant anthropogenic pressures, so it is questionable how much the evaluation is relevant for the entire coastal area the assessment is partially reliable. GES is not reached. |
Levels of contaminant effects measured in seawater, sediment and biota at potentially impacted coastal stations were below or in the range of established good environmental status. GES is reached. |
Levels of contaminant effects measured in seawater, sediment and biota at potentially impacted coastal stations were below or in the range of established good environmental status while a “good ecological potential” (GEP) was achieved at stations placed in areas such as harbours, industrial areas, etc. classified as heavily modified water bodies (HMWB). GES is reached. |
Due to the lack of adequate data on the biological effects of acute natural concentrations of heavy metals in the sediment of the Adriatic. The assessment is unreliable. |
