Volunteers will also take to the field to free one of the tanks in the Poetto salt pans from the thousands of terracotta clay pigeons thrown in the past by the former skeet shooting facility in Quartu . There is already the availability of various Quartese groups but also of university students, who have already welcomed the proposal of the Molentargius park institution.
A deployment that will strengthen the task force that will soon take the field to put its hand to the reclamation financed by the regional environment department with 440 thousand euros.

Two interventions of the project. The first - that of making the emergency safe - consists in the removal from the site of the clay pigeons and their subsequent transfer to the landfill. « The need to recover them is certainly not imposed by the material with which they are built, i.e. terracotta, but by the binders used in the manufacturing, i.e. pitch. This is toxic to the environment. From here, as imposed by the ministry, the removal», explains the biologist of the Molentargius park, Laura Durante.
No danger, however, for humans. For this reason, the collection of clay pigeons does not prevent the involvement of volunteer teams.
When the clay pigeons have been collected, the second phase of the project will proceed: the so-called characterization of the area. The investigation which will have to ascertain whether there is a form of pollution in the bottom of the tank. Only in that case will the remediation have to be implemented.
«In reality - explains Durante - the area has been under strict control for years. The lead pellets from the shooting during the activity of the skeet shooting range are disrupted since we are talking about a plant that has been closed for decades. It is clear that the Park has also paid attention to the risks for birdlife linked to the presence of lead, but a case of lead poisoning has never been found". The pathology linked to exposure, in this case of birds, including flamingos, to this metal.
