The entry into the Mar Menor of waters laden with nitrates not only happens these days in the Albujón Rambla, but also affects other parts of the environment that are especially vulnerable. The case of the Lo Poyo salt marsh stands out, a wetland protected by its ecological values and where the dragging of streams contaminated by the presence of chemical substances has flooded several areas.
The flooding of this natural space, close to Los Nietos, has unleashed complaints from citizens through internet social networks. Sources from the Ministry of the Environment assured that, according to their technicians, the waters do not come from nearby farms but from the Campo de Cartagena aquifer. They indicated that, as in the Rambla del Albujón, they are outcrops due to the high water table of the underground mass.
The regional government sent the Segura Hydrographic Confederation (CHS) to report on the measures planned to tackle the problem. And sources from the state administration pointed out that the aquifer is polluted by nitrogen, an element used in intensive agriculture; that the Ministry is working on various solutions; and that the Community has among its competences the control of the use of nitrates, in accordance with European regulations.
IEO detects low oxygen
On the other hand, the researcher of the Spanish Oceanographic Institute (IEO) Juan Manuel Ruiz affirmed yesterday that the state of the Mar Menor, where thousands of fish and crustaceans have died in the last nine days, is a consequence of low oxygen concentrations, which it has “toxic consequences” for marine organisms. He explained that the IEO has been monitoring the waters for more than 30 years and that it is analyzing the reasons that caused the current situation.
Ruiz clarified that, “seeing how the system behaves” and its complexity, the lagoon can “turn one way or another”; that is, your condition can both worsen and improve as the days go by.
