UN letters include harsh criticism of Swedish government and Boliden mining company Over 30 years after Swedish mining company Boliden shipped almost 20,000 tonnes of toxic mining waste to the Chilean city of Arica, a group of United Nations Special Rapporteurs have made allegations of serious ongoing human rights abuses, exposed in the ARICA documentary, which continues it’s festival run with screenings in Spain, Czech Republic, Italy and Belgium in the coming weeks. Exposure to the waste led to numerous cases of cancer, birth defects and serious diseases, with the Chilean government estimating that around 12,000 people were exposed to the toxins.
