Air quality in Ukraine's Ternopil re-tested after Russia’s attack: What is known

In Ternopil, the air was retested for pollution after Russia’s attack. The air quality has normalized, according to the city’s mayor, Serhii Nadal, on Telegram.
He noted that the Ternopil Regional Center for Disease Control and Prevention conducted repeated measurements of atmospheric air at nine locations across the city as of 12:00 p.m. Kyiv time.
The levels of carbon monoxide, nitrogen dioxide, and chlorine are within the permissible limits set by Ukraine’s Ministry of Health. The radiation background is also within the normal range.
"Measurements will continue throughout the day. It is safe to go outside," the mayor stated.
On the night of June 6, Russia launched missile and drone strikes on Ternopil. Industrial facilities and infrastructure were hit. The head of the Ternopil Regional Military Administration described today’s attack as the most massive since the start of the full-scale war.
Fires broke out in Ternopil as a result of the attack, and smoke was observed. After an inspection, some harmful substances were detected in the air.
Residents — especially children and the elderly — were advised to stay indoors and keep windows closed.
Massive Russian attack
In the early hours of June 6, Russia launched another large-scale assault on Ukraine, using Shahed drones, cruise missiles, and ballistic missiles. The strikes targeted Kyiv, Chernihiv, Lutsk, Ternopil, Kremenchuk, as well as Kyiv and Lviv regions.
In Kyiv, the attack tragically claimed the lives of three rescuers, and over ten other emergency workers were injured.
In Lutsk, a nine-story building was damaged by a Russian strike. Rescuers recovered the body of a young man from the rubble.
