Concerns are spreading across Central Asia after powerful explosions at oil storage facilities in Tehran, Iran, reportedly released large volumes of hazardous chemicals into the atmosphere, potentially creating toxic rainfall and air pollution.

Forecasters expect unfavorable meteorological conditions in Almaty, Kazakhstan on March 9. These conditions-such as calm winds, fog, and temperature inversion-can trap pollutants near the ground and worsen air quality, The Caspian Post reports via Kazakh media.

Experts advise residents to limit outdoor physical activity and reduce time spent outside during this period. People with chronic lung, cardiovascular, or allergic conditions are urged to carry necessary medications and take extra precautions.

The explosions and subsequent fires at the oil depots reportedly released large amounts of hydrocarbon compounds as well as sulfur and nitrogen oxides into the air. Such emissions can lead to toxic acid rain, which may cause chemical skin irritation and pose serious risks to respiratory health.

Meanwhile, social media posts circulating on March 8-9 claim that a toxic cloud could be moving toward Central Asia.
