Anyone who is not used to it notices right away the contaminated air. Inhaling the so-called iron dust — an unpleasant mixture of iron ore pellets and coal dust — provokes headaches, itching skin and breathing difficulties. And in the long term the impact can be deadly.
Respiratory allergy is one of the first symptoms you feel on arriving in the small village of Piquiá de Baixo, in the town of Açailândia, located in the interior of Maranhão State. The iron dust is emitted by the five steel factories that process ore coming from the giant Carajás mine.
“This is what happens to those who are not used to the iron dust”, says Wellem Pereira de Melo, one of the representatives of this community of 300 families. Under instructions from his doctor, 56-year-old Melo had to move out of Piquiá de Baixo to another neighbourhood two kilometres away. He was told that it would be dangerous for him to go on breathing the polluted air.
Long-term exposure to the dust may cause severe health problems and attack the body’s immunity to lung disease. The dust in Piquiá is a mixture of carbon, manganese, chromium, copper, nickel, phosphorus and silicon. In the long term, the chronic effect of breathing this air may be the development of black spots on the lung.
It is not unusual to find Piquiá’s inhabitants with lung complications.“The particles enter our airways and go to the lungs. It is likely that everyone in Piquiá will have a lung problem in the future”, says Joselma Alves de Oliveira, a 37-year-old teacher who has been suffering over the last decade with an intense throat irritation and inflammation of the ear.
For Antônio José Ferreira Lima Filho, the representative of the Centre for Defense of Life and Human Rights in Açailândia, an NGO founded in 1996, what is happening in this neighbourhood is a powerful indication of the negligence of the authorities with respect to the impact on human lives of the production of pig iron in the region.
“There is no other place in Maranhão where human rights are violated to the same extent as they are here. The coexistence between the pig iron production and human settlement, which has happened for 20 years, can’t go on. The community will end up forced out of this place, even though they were the first to arrive”, says Antônio Filho.
The pollution can be seen with the naked eye, adds Danilo Chammas, a lawyer and a member of Rede Justiça nos Trilhos (Justice on the Rails Network), who speaks for the community of Piquiá.
