Laguna de Rodrigo Freitas,
en Río de Janeiro.
Desde la
semana pasada se han retirado más de 33 toneladas de peces muertos de la Laguna
de Rodrigo Freitas, en Río de Janeiro.
Es aquí
donde se albergarán las pruebas de remo y canoa en los Juegos Olímpicos de
2016.
El mal olor
de la Laguna Rodrigo de Freitas había provocado las quejas de los vecinos y de
miembros de los clubes de remo locales.
El
secretariado de Medio Ambiente de Río de Janeiro dijo el jueves que las muertes
fueron el resultado de un cambio repentino de la temperatura del agua pero
según científicos y ecologistas los peces murieron por la contaminación.
La calidad
del agua es una de las principales preocupaciones de los organizadores de las
Olimpiadas, no sólo en esta laguna sino también en la Bahía de Guanabara, donde
se celebrarán las pruebas de vela.
More than 33 tons of dead fish were
removed from Rodrigo Freitas Lagoon in Rio de Janeiro, which will host the
rowing and canoeing at the Olympic Games in 2016.
This has been the result of work by a
team of 60 people who try to clean the pond of the carioca capital since last
week.
According to scientists, the fish died
from lack of oxygen caused by pollution.
Water quality is also a major concern of
the organizers for the tests to be held in Guanabara Bay, where the sailing
events will be held.
The stench of Lagoa Rodrigo de Freitas
had provoked complaints from neighbors and members of the local rowing clubs.
The Secretariat of Environment of Rio de
Janeiro said Thursday that the deaths were the result of a sudden change in
water temperature, but scientists rejected the explanation,Bloom began de Paul Rosman, an oceanographer working in
the lagoon told Reuters that a rapid increase in the population of algae, known
as algal bloom, caused the increase of carbon dioxide in the water.
"There was a great effort to reduce
wastewater and took everything," said Rosman. "But reducing
wastewater does not mean reducing algal bloom. That happens by the excess
nutrients in the water."
It is not the first time they appear
tons of dead fish on the surface of the lagoon.
According Rosman, both the city
government and the state of Rio de Janeiro have ignored proposals to improve
water quality, draining canals that connect the lagoon to the sea.
The governor of Rio de Janeiro, Luiz
Fernando Pezao, acknowledged this week that "not going to give time"
to finish cleaning before the Games next August.
In January, government officials said
they could not meet its goal of reducing pollution of the waters of Guanabara Bay
by 80%.
