The Tubarão Port is the largest iron ore export terminal in the world. It is located in Victoria, the capital of the State of Espírito Santo in Brazil. Since 2009 people in the neighborhoods noticed "black powder" in their environment and especially inside their homes. This "Black powder" is a combination of iron ore and others pollutants present in the air because of the activity of the Tubarão Port. In February 2015, the local legislature set up a Parliamentary Commission of Inquiry (PCI) to find out the responsibility, and they concluded that Vale, Arcellor Mital and Samarco are the companies responsible for this emissions.
