The Metsul meteorological observatory in Brazil has warned of the imminent arrival of black rain that could affect parts of Argentina, Uruguay and the national territory in the coming days, although the first contaminated rainfall has already begun to be observed in neighboring countries.
In Uruguay, this type of precipitation has already begun and users of the social network X have shared images of the black water.
ARGENTINA
At Argentina, at least 14 provinces, in the Northeast, Center and Cuyo regions, in the northwest of the country, are on alert for the arrival of these rains. Here are 10 of these provinces: Misiones, Corrientes, Formos, Santiago del Estero, Chaco, Jujuy, Salta, Catamarca, Santa Fe and Tucumán.
The statement from the Argentine Ministry of Health indicates that "a smokescreen from the ongoing forest fires in Bolivia reached the Buenos Aires Metropolitan Area (AMBA) today (11 SEPT 2024).
SOOT
According to MetSul Meteorology (Brazil), this water is also known as soot rain. It is a material composed mainly by carbon, which originates from the incomplete burning of organic materials, such as fossil fuels (coal) and biomass (wood and agricultural waste).
When burned, these materials, instead of transforming pollution into carbon dioxide (Co₂) and water vapor, generate fine dark particles of carbon and other compounds.
Since this new formation is extremely small, with diameters on the scale of nanometers and micrometers, the particles remain in the air for long periods and can travel great distances.
THE PHENOMENON

The phenomenon occurs when soot and other polluted compounds in the atmosphere mix with humidity and fall to Earth carryed by rain water.
MetSul Meteorologia also reported that this type of rain is indicative of high levels of pollution and is usually recorded in industrial areas, fires or where there is intense burning of fossil fuels.
When this substance reaches the ground, it contaminates forests and places where water accumulates. In addition, it leaves a layer of dirt on the surface, visible on buildings, vehicles and other structures.
The term black rain refers to similar events, such as those that occurred in Hiroshima after the explosion of the atomic bomb in 1945, when the rain accumulated dust and soot from the atmosphere.
HEALTH-RELATED RECOMMENDATIONS
Experts state that the so-called “black rain” does not pose a direct risk to health, but it may have contracted contracts for some people.
The National Meteorological Service of Argentina (SMN) has put 14 affected provinces on alert and the Ministry of Health has issued a series of recommendations in a press release.
These measures are aimed at people with chronic respiratory diseases, cardiovascular diseases, allergies or other risk conditions:
Avoid smoking: this will increasing air pollution! 😱
Keep windows and vents closed.
Use the “ventilation” or “recirculation” mode on your air conditioning.
Reduce sources of indoor air pollution.
Place cloths or towels under doors and windows to prevent smoke from entering the home.
Do not light candles or fireplaces.
Be careful when driving due to poor visibility and low beams.
Wear masks that fit snugly to your face to reduce exposure to smoke and ash, especially for those who work outdoors.
Suspend outdoor activities such as walking and running.
