Riparbella The quarry is a problem for all The nuisance of ophiolitic material (green rocks, or grabbriccio in our area) has been known for decades. Medicine democratic complaint for many years, especially in recent years, since facing massive new Excavations at the service of a motorway. E 'known case of Pallet Town in the province of Catania, where they had to undertake massive reclamation works to neutralize the previous massive use of green rocks. They are also known carcinogenic effects on the population of Pallet Town, which has been subjected to epidemiological studies, finding her suffering from diseases from exposure to asbestos well above the national average. Even in Piedmont and Emilia have implemented clean-like, the parking of the central railway station. The harmfulness of the "green stone" can be found on DPR August 8, 1994, in particular art. 4 "Preparation of programs for dispose of the mining operations and implement its remediation, "and the Decree of the Ministry of Health, 14.5.1996 (OJ 251 of 10.25.1996 suppl. ord.) establishing criteria for the controls. Finally and most importantly the law 257/1992 (the basic law on asbestos) expressly prohibits the extraction and marketing of asbestos or asbestos-containing products, as in our case the gabbriccio. After these laws there have been studies by different regions, confirming the strong presence of asbestos in these rocks. In Tuscany, the Province of Pisa is more involved, especially the Val di Cecina, with dozens of caves that the Province has decided to reopen or continue to benefit, even in relation to the construction of the new highway (1) Although they are present and widespread also in our area quarries that do not contain asbestos (eg limestone or basalt), the authorities continue to inexplicably give permission to the bait, like that of Rialdi, and although it is certain that these permits involve public exposure to asbestos. These permissions - such as that granted by the City of Riparbella June 15, 2010 - are based on the alleged harmfulness of asbestos is not below a certain limit, but according to many researchers, including Lorenzo Tomatis - Director of IARC for 12 years - Dr. Vito Totire professor at the University of Venice and the prof. Giancarlo Ugazio there is no acceptable threshold for carcinogenic substances, especially asbestos. Even a low exposure, even a single fiber, can cause cancer of the pleura (mesothelioma), even decades after exposure. But in the case of Rialdi, exposure of the population would be massive and continuous: the second "release indication" of asbestos fibers into the atmosphere and ARPAT made by ASL to the quarry (18.74 milligrams per kilogram of material extracted (2 )) multiplied by the quantity pull-out in the 15 years of "safety measures" (sic), it bears much an issue of 101,196 pounds of fiber (3). Apart from direct exposure, it should be noted the very wide and growing use of green rocks crushed sand in housing, which grows with the unwinding of the sands of the river, and involving thousands of construction workers and families themselves. The lethal combination of exposure to asbestos and asbestos green rocks from industrial applications (shipbuilding, industrial equipment such as Solvay Piombino steelworks and oil refinery in Livorno) is the province of Livorno in Italy one of the four - along with Taranto, Alexandria and Gorizia - in which are more numerous cases of mesothelioma 4). From the 'Archive mesothelioma "of Regione Toscana is that the province Livorno suffered three times the regional average of mesotheliomas (index 7.67 v 2.53), and we know that many - perhaps most - of the material excavated in the foothills, is used in coastal towns like Cecina, Rosignano Donoratico etc. located in the Province of Livorno. It remains to investigate the effect of the runoff of rain on the roads to quarries and gabbriccio and then infiltration of asbestos fibers into the groundwater and surface water, resulting in pollution of the local food chain, in an already abnormal as worrying state drinking water distributed by seven years notwithstanding the legal limits for arsenic, boron, the Trihalomethanes and chlorites. (5), not including chromium, mercury, turpentine, etc.. How easily intuits the problem quarry is not a problem limited to Riparbella, but the whole Val di Cecina. By the end of October, the City of Riparbella should release the final authorization for the "fugitive emissions" means the population will take the opportunity to force the municipality to admit you were wrong so far and to deny the final authorization for the best interest to population health. At the same time democratic Medicine calls for the closure and the safety of all the quarries of green rocks of the Val di Cecina, and ascertaining the health effects of population and exposed workers. Note 1 - the reopening of the quarries, see the website of the Province of Pisa, 26.2.2009 informed the two - see the investigation report to the City of ASL Riparbella 11 .12.2009. 3 - the calculation made by democratic Medicine is based on a quantity removable media, not the greatest city in the authorization assumed. The calculation is shown below. 4 - See the National Institute of Health Study of 2002 Mastrantonio, Belli, Comba et al. 5 - drinking water, see the regional derogation in force, Decree 1587 of 4/9/2009, with the municipalities involved and the relevant pollutants in derogation from the limits law. Quarry Rialdi (Riparbella - Pisa) Issue of asbestos fibers into the atmosphere Index release 18.74 milligrams per kilogram (ASL Report 12/11/2009) 18.74 mg X 1000 = 18,740 mg = 18.74 grams per tonne Release of asbestos per tonne of material extracted. Material Release 3,600,000 cubic meters (400,000 cubic meters for 9 modules = 3,600,000 cubic meters. The range authorized by the municipality, on the recommendation of the Province of Pisa, is between 100,000 and 600,000 cubic meters per module. Specific gravity of the material excavated estimated 1 Meter cube = 1.5 X 1.5 = 5,400,000 tons 3,600,000 tons 5,400,000 tons of extractable X 18.74 grams per tonne = Release 101.196.Kg fibers released into the atmosphere That is 101,196 pounds of asbestos released into the atmosphere, where the extraction of material is 3.6 million cubic meters, based on the given index "release" of ARPAT 2007, mentioned in the report of the ASL 6 11 .12 .2009. To this amount must be added the amount of fiber that are mobilized in the years to the destination of gabbriccio (roads, squares, walls, etc.), air and water. 23.9.10 Maurizio Marchi (Manager Livorno and Cecina Valley)
