| GES description | D8C1 Contaminants in environment (8.1, 8.1.1) | Coastal: GES will be achieved when the concentration of the hazardous substances is close to the background levels or, for those discharges in the marine environment from human activity, close to zero Open sea: GES will be achieved when the concentration of the hazardous substances is close to the background levels or, for those discharges in the marine environment from human activity, close to zero |
8.1.1. Water: Concentrations of heavy metals in the Romanian marine waters observed during 2006 - 2011 recorded the following average values and range of variation: copper 10,02 ±13,77 µg/L (0,01-93,51 µg/L); cadmium 0,99 ± 1,26 µg/L (0,01-18,32 µg/L); lead 3,78 ± 6,03 µg/L (0,01-51,97 µg/L); nickel 3,65 ± 4,40 µg/L (0,01-30,59 µg/L); chromium 3,84 ± 6,26 µg/L (0,01-59,74 µg/L) . In relation to environmental quality standards in the field of water recommended by national legislation (Order 161/2006 for approving the Norms on surface water quality classification to determine the ecological status of water bodies), the percentage of samples investigated in the period 2006-2011 which exceed the proposed limits vary by element, area, season, special hydrological events as follows: 7.8% copper, cadmium 1.2%, 9.4% lead, nickel and chromium 0%. Differences in spatial distribution of heavy metal concentrations in marine waters highlights in some cases river contribution (Danube) in the northern sector (lead, nickel, chromium) and terrestrial sources of pollution in the southern sector (lead, chromium) (harbours, WWTPs: Mangalia, Constanta South). In comparison, the values observed in marine waters along the East Constanta transect that goes up to 30 nm far from the shore are often reduced (copper, cadmium, chromium) . Different trends, depending on the element, were noticed. In general, the annual values fall within specific areas of multiannual variability, with some trends of stabilization in recent years (eg, nickel). Slight increase in recent times have been observed for copper and lead, while a slight diminishing of chromium and cadmium was observed. |
