Air quality reaches terrible levels in cities in Amazonas and exceeds the limit considered good by up to 15 times

Air quality is considered good by Selva when the concentration of particles is between 0 and 25 µg/m³. Above this limit, the indices undergo classifications that vary from moderate to very poor, depending on the scale used by the system.

In Parintins, the index recorded by the sensor positioned in the municipality reached 332.3 µg/m³. In Vila Amazônia, located in the rural area of ​​the municipality, the scenario was even worse: 392.5 µg/m³, around 15.7 times above the maximum limit considered good.

In Barreirinha, also in the Lower Amazon region, the concentration reached 306.7 µg/m³, at around 8:20 am, according to Selva sensors.

Other municipalities also recorded high rates. In São Sebastião do Uatumã, the concentration of polluting particles reached 154.8 µg/m³. In Itapiranga, the sensor recorded 161.1 µg/m³.

Data consulted in the system about the municipality of Itacoatiara also shows the air quality was considered very poor, with 90.8 µg/m³ at around 8:30 am. In Silves, the index reached 109.5 µg/m³.

On Monday (9), the gum situation caused by fires was already critical in Parintins, leading to the suspension of classes in the municipal and state education networks and the cancellation of commercial flights. According to the terminal administration, the Azul commercial flight scheduled for that day was canceled due to low visibility.

Parintins airport operates by visual reference. This means that the pilot needs to be able to see the runway to make safe landings and takeoffs, even with the navigation aids available.

In addition to commercial flights, the situation also affected air medical transport operations, used to take patients to other municipalities, and other essential services.
