I present a work made with rayographs with expired paper, which does not allow the white to be white of a torrent called Lura in Italy. This torrent, runs for 45 km from its source at the border with Switzerland to the gates of Milan, where it meets the Olona river. For years it has been in the headlines for the discharge of pollutants deriving from factory waste and illegal dumping of chemical and toxic substances. In the past, there was also a case of a nuclear disaster in which a high percentage of Celsium was found in the waters of the river. So, today, we find pollution stains on the stones, leaves with stains and strange colours. I am very indignant because I would like my daughter to be able to play in its waters, and I don't want to keep her away because the water is toxic.
