<s>[INST] The next text is a question of a member of the European parliament:"According to press leaks, internal mechanisms have allegedly been set up at the Ercros plant in Flix to conceal double accounting in practice with regard to the use, transport and loss of mercury in the industrial processes carried out at this and other plants owned by this corporate group in Spain.   These suspicions come on top of doubts about the reliability of the register of emissions and leakages of mercury in the Flix area. Such doubts have been expressed by organisations such as Ecologistas en Acción, who have denounced the environmental and health risks arising from possible breach of the regulations on mercury.   Is the Commission aware of the data on the use, transport, storage, emissions, losses and leakages of mercury at the Ercros industrial complex in Flix?  Does it consider that these data and measurements are reliable? If not, what steps has it taken or will it take to verify compliance in this case with EU regulations?"
