The two municipalities presented concentrations above the range considered terrible on the scale of the Electronic Environmental Surveillance System (Selva), of the State University of Amazonas (UEA).

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

In addition to Parintins and Barreirinha, other cities in the same region also recorded terrible air quality at the same time. In Itapiranga, the concentration was 197.5 µg/m³, while Silves recorded 170.3 µg/m³. The municipalities of Nhamundá (135.4 µg/m³), Itacoatiara (143.3 µg/m³), Urucurituba (149.7 µg/m³) and Maués (132.4 µg/m³) were also in the range considered very poor.

Still in the east of the state, São Sebastião do Uatumã recorded 89.5 µg/m³, an index classified as very poor. In Urucará, the measurement was 51.8 µg/m³, considered bad.

The municipality of Parintins recorded a series of forest fires throughout the week. In Vila Amazônia, a fire at Fazenda da Esperança, linked to the Catholic Church, mobilized volunteers and residents to try to contain the fire, which was advancing through the forest.

On Friday night (6), Civil Defense sent an alert to residents of Parintins about air quality. The agency recommended the use of masks and advised the population to avoid exposure to smoke.

Pollution also harmed air quality in municipalities in the Manaus Metropolitan Region. In Iranduba, the sensor registered 108.8 µg/m³, an index considered very bad. In Autazes, the concentration reached 79.3 µg/m³, also considered very bad.

Careiro da Várzea and Novo Airão presented measurements of 59.3 µg/m³ each, classified as poor.

In the capital, the rates varied between moderate and bad. At 8am, the worst measurement was recorded in the Morro da Liberdade neighborhood, with 52 µg/m³. The only sensor in Manaus to indicate good air quality was the one installed near Eduardo Gomes International Airport, with 21 µg/m³.
