## 🎯 Key Points

- Kyiv was blanketed on the morning of September 30 by dense fog mixed with smoke from previous shelling.
- The SES explained that a calm atmosphere and lack of wind prevent the dispersion of combustion products.
- The SaveEcoBot system recorded a moderate (yellow) level of air pollution with PM2.5 fine dust.

On the morning of September 30, 2026, Kyiv residents faced an unprecedentedly dense fog and haze that blanketed the capital in a thick layer. Social media and local channels were instantly filled with footage of the gray veil, which significantly reduced road visibility and caused concern among citizens. Many mistook the natural phenomenon for industrial smog, prompting official explanations from specialized agencies.

### Causes and official position of the SES

The press service of the State Emergency Service of Ukraine promptly responded to public concern, confirming heavy fog in the city. According to rescuers, the visual effect was intensified by the aftermath of recent shelling and fires. Residual smoke and combustion products rose into the upper layers of the atmosphere, where they mixed with natural air masses in the complete absence of wind.

### Environmental situation and air monitoring

In addition to visual discomfort, the situation affected environmental indicators. According to the Ukrainian monitoring system SaveEcoBot, as of 9:00 AM, a moderate level of air pollution marked in "yellow" was recorded in certain districts of Kyiv. The main pollutant was fine particulate matter (PM2.5), the index of which was calculated using the NowCast formula.

### Recommendations for residents and drivers

Experts emphasize that a moderate pollution level may cause only minor discomfort in sensitive categories of citizens. However, rescuers and relevant services recommend avoiding prolonged outdoor stays, keeping windows closed, and following road safety rules. Drivers are strongly advised to turn on fog lights and maintain an increased following distance due to poor visibility.
