“Environmental disaster in Brazil” Mud will achieve 9 km of sea
The onslaught of mud from the dam broken on Mariana (MG) should achieve an area of 9 km of the sea along the coastline of the Holy Spirit. And, although impacts in the ocean should be less drastic than in the Vale do Rio Doce, they can be lasting and affect, for many years, the presence of algae, molluscs, crustaceans and fish.

The scenario was drawn by researchers like Paul Rosman, from UFRJ (Federal University of Rio de Janeiro), who made a mathematical model already cited as a reference by the federal government. It minimizes the possibility of significant impacts on Abrolhos region -banks coral 210 km from the mouth of the Rio Doce, in Bahia, which are rich in marine life, attracting even whales. But according to Minister Izabella Teixeira, head of the Environment folder, “which will impact there will be.” “We’ll just evaluate everything after that is over,” he said. The simulations, there will be a mud dispersion 3 km north of the coast and 6 km south.


Disruption on the last day 5 of the dam Samarco mining company controlled by Vale and Anglo-Australian BHP Billiton, triggered a “mud tsunami” that has come to the Holy Spirit and left 12 missing and seven dead -In four bodies have not identified. Mining towns and Espirito Santo had their compromised water supply -like Colatina (ES), more than 400 km from the dam. Thursday (19), the Federal Court ruled that the mining prevent the arrival of the mud to the sea, subject to a daily fine of R $ 10 million.

Samarco says it is studying the decision. To stop the mud, it would be necessary to make physical barriers to divert waste from the river-operation considered complex by experts.

According to monitoring done by the Geological Survey of Brazil along the river Doce, the mud should only reach the ocean next week. On Sunday, the mass of clay and silt, sediment with very fine grain, is expected to reach Linhares (ES), the last town before the ocean. “The mud should get just as muddy water to the ocean,” said Paul Rosman, UFRJ, an expert in coastal oceanography.

DISASTER The Minister Izabella Teixeira said that the reconstruction of river basin Sweet “is not trivial.” “At a minimum it will take ten years with great generosity of nature. You blew the entire food chain of the river, including terrestrial fauna, because much of this fauna depends on the river.” A task force formed by workers, volunteers and fishermen was working at the mouth of the Rio Doce, in Linhares, to try to prevent the round of mud to the sea. Floating barriers, similar to those used to contain oil spills were being scattered around the site. This measure, however, is not sufficient to prevent debris from reaching the ocean.

The biologist Andre Ruschi, director of the Marine Biology Station Ruschi, in Santa Cruz, near the mouth of the Doce, is one of those who claim that the mud to reach the sea, will have impacts on the environment for a long time. The chain of underwater mountains that begins at the mouth of the Sweet and spans over 1,200 km is one of the biggest points of biodiversity of the Atlantic.

“There is a lot of life because of this mountain range, interfering with currents and retains the nutrients carried away by the rivers.” According Ruschi, “it will take up to 300 years to get rid of the consequences of this crime.”
