The phenomenon known as “Black Acid Rain” in Iran has raised global concern after viral images showed dark-colored rain linked to smoke from ongoing conflicts. This type of rain occurs when carbon soot, toxic dust, and gases produced by explosions or the burning of fuel—such as attacks on oil facilities—accumulate in the atmosphere. When these pollutants mix with rain droplets, the rain can appear dark and become more acidic than normal.
Such rain may pose health risks, including irritation to the respiratory system, skin, and eyes. Some pollutants from oil combustion also contain substances that may increase cancer risk with long-term exposure. Experts recommend avoiding direct contact with unusual rain, wearing protective masks such as N95 when outdoors, and washing the body immediately if exposed.
Although the likelihood of black rain reaching Thailand is very low due to the long distance, experts note that air pollution can travel across borders. The situation serves as a reminder of how environmental impacts from human conflicts can affect the global ecosystem.
