It should be highlighted the presence of iron in the irrigation ditch of Rascanya above the permitted parameters established in mg/l. It seems a punctual waste or there is a seasonal reason as a further analysis shows the iron concentration.
We also found high ammonium concentration in the Albufera (3 mg/l versus to 0,5 mg/l permitted). It could be due to the use of fertilizers in the fields of rice close to the lagoon.
-
The variations of the values, especially for ammonium and iron, can not directly correlated with environmental impacts, because there is a lack of accurancy in the analyzing system (in all countries the same range of variation could be observed).
-
Therefore for the surface water in all countries the parameters measured are in a good range, within the limits of the EU.
-
The variation of the oxygen values are big, because the measurements were taken in winter and summer. There a no informations for the values of the EU for the seasonal variations.
