Porto Velho woke up covered in smoke this Friday (2).
Aerial images show the size of the "cloud" of pollution caused by the fires registered in the region.
A survey by IQAir, a Swiss technology company that measures pollution levels in several countries, showed that the air breathed by residents of the capital of Rondônia is the worst in the country this Friday.
According to IQAir, the index recorded was 272, considered "very unhealthy".
The higher the IAQ, the more polluted and harmful the air is.
The classification varies between "Good", "Moderate", "Unhealthy for sensitive groups", "Unhealthy", "Very unhealthy" and "Dangerous".
According to the levels indicated by the Purple Air system, the number is alarming and poses a risk to the health of anyone exposed to it for 24 hours.
Real-time satellite images that detect the presence of Carbon Monoxide (CO) in the atmosphere show that Porto Velho is in a region with the highest concentration of CO in Brazil.
The gas is generated mainly by the use of fossil fuels (oil, coal and natural gas).
Experts attribute the new deforestation fronts, the expansion of pastures in the south of Amazonas and the fires in the region as the main causes of the poor air quality.
One of the main air pollutants in the capital of Rondônia is PM 2.5, an ultrafine inhalable particle that is more difficult to eliminate from the body.
