In southern Brazil, black rain falls in many places due to forest fires

On September 12 local time, the meteorological observation agency of Santa Catarina state in southern Brazil released news that black rain appeared in some areas of the state and Rio Grande do Sul state adjacent to it. Areas such as Chapecó, Maravilha and Sete Quedas are more seriously affected by “black rain”.

The Brazilian civil defense department pointed out that when the concentration of pollutants in the atmosphere is high, black rain will occur. The appearance of this “black rain” is closely related to the continuous forest fires in the Amazon region. Since August this year, the smoke and dust formed by forest fires have continuously spread to various parts of Brazil. Previously, “black rain” has also occurred in Rio Grande do Sul state and Uruguay, a neighboring country of Brazil.

Forest fires occur from time to time in Brazil and have appeared frequently this year. The reasons are relatively complex, including natural factors such as dry climate and strong winds, as well as possible human-caused arson. Fires not only cause serious damage to the local ecological environment, burning large areas of forests and vegetation, but also have many adverse effects on the lives and health of residents.

Since “black rain” may contain toxic substances harmful to health, especially affecting respiratory health, relevant departments recommend that people avoid direct contact with rainwater and do not use it as domestic water. At present, the local government and relevant departments are closely following the development trend of forest fires and taking corresponding measures for firefighting and rescue work to reduce the losses caused by fires.
