THE Polychlorinated biphylenes I'm a class of organic compounds highly pollutants whose toxicity is comparable to that of dioxin. The polychlorobiphylenes, also known by the acronym PCB, are dramatically known in the Brescia area: Brescia and Anniston (USA) represent the major cases worldwide of PCB contamination in the waters and in the soil. In one of the latest investigations by Direct plug, Rai Tre's in-depth program, the spotlight has turned on the case Brescia.
The Rai Tre program, conceived and directed by Riccardo Iacona, traveled to Boston to interview Philippe Grandjean, professor and scientist at Harvard University. Philippe Grandjean has been studying the effect of compounds for over twenty years polychlorinated biphylenes on human health. The scientist found that exposure to PCB, in addition to causing various types of cancer, seriously compromises the proper functioning of the immune system and the endocrine system.
The production of PCB was banned for the first time in Japan in 1972, after 5 years the ban reached the United States but to get to Italy it took 11 years, in fact, until 1983, to Brescia, the Caffaro factory produced PCB. The production of PCB in Brescia it lasted 51 years, from 1932 until the year of the ban. According to the reconstructions and analyzes of the ASL, the Caffaro factory has polluted heavily the territory with an amount of 150 tons of pure PCBs. Nothing has been done for the past few years reclaim the territory and the most recent surveys show that Brescia residents have PCBemia values up to 20 times higher than the reference values. As far as the territory is concerned, in 1999 the Brescia ASL found a quantity exceeding 5,000 times the limit values set by Ministerial Decree 471/1999 and in June 2001, further investigations did not see any improvements, so much so that a complaint of environmental disaster from the Republic of Brescia.
As mentioned, that of Brescia is a unique case in Europe but not in the world. The citizens of Anniston, Alabama, suffered a similar fate due to a company similar to Caffaro that produced and contaminated the terriotorio with tons of PCBs. Direct Presa conducted a survey to closely observe what happened to the citizens of Anniston and discovered an entire sick community. The only big difference is that the Alabama company was brought to court and sentenced to pay 700 million dollars and obliged to provide for the expenses necessary for land reclamation. Nothing similar has happened in Italy and no concrete works by quenching and tempering.
