Sao Paulo air quality map

What causes higher pollution levels to show up on the air quality map in Sao Paulo?

Whilst some of the factors that lend themselves to higher air pollution levels in Sao Paulo have been touched on briefly in the article over the various parts of how the air quality map works, and what its readings consist of, a few more of the main polluting sources will be discussed. This is again for educational purposes so that users can better understand the readings that they see for the air quality map above, as well as what is causing higher US AQI readings in Sao Paulo, which also pertains to many other cities throughout India, with many of them having similar root causes. With the country of India itself having one of the largest population numbers in the world, which will only be on the rise, there is naturally a tendency toward having higher amounts of air pollution present whenever there are large groups of people. Indian cities can have large populations, as well as many people traveling in and out of the city, with the transportation industry also contributing to rising pollution levels. Wherever there are large amounts of people there will be some forms of pollution being given off as a result, particularly when it comes to movement. This refers to polluting sources such as cars, motorbikes, and fumes given off by heavier freight vehicles such as lorries, trucks and buses, which can raise ambient, year-round pollution readings on the air quality map for Sao Paulo. The ambient pollution level refers to that which stays consistent throughout the year due to sources that continue to emit particles, chemical compounds and smoke.

Fumes from vehicle exhaust contain many of the chemical compounds used in the US AQI readings, along with many forms of particulate matter, which also raises the US AQI level further due to particle-based pollution being a significant component of air pollution levels, as seen above on the air quality map, as well as on the city page for Sao Paulo, which shows the pollution levels as an average, rather than as individual areas throughout the city. Whilst combustion inside vehicle engines is a significant contributor to higher pollution levels, vehicles can also contribute in other ways (although older and poorer quality cars, motorbikes and lorries will often give out far more noxious fumes and particles than newer models do, due to the poor combustion process taking place in the engine, leading to improper combustion of fuels. This can release materials such as black carbon and volatile organic compounds (VOCs) in higher quantities, as well as older engines are also more likely to release oil vapors). The other ways that vehicles can contribute to higher air pollution readings on the pollution map above is from less well-known aspects such as the residual wear and tear of tire treads causing many tons of microscopic rubber particles to enter the air (as well as settling on the earth or in bodies of water, leading to these particles potentially entering the food chain and making its way to people, and also causing damage to the environment).

What readings are present on Sao Paulo’s air quality map?

The pollution readings for the air quality map, or air pollution map as it can also be referred to, are shown in the form of US AQI readings, which stands for the air quality index, with the US part indicating that it follows the air quality classification measures used in the United States, which are far more stringent than other measurement systems used throughout the world. As such, pollution readings that other systems may use could be classified as being safer, when in reality they may be a cause for concern, particularly amongst vulnerable groups. To cite some readings taken from late August of 2022, US AQI readings of 18, 22 and 45 were taken in Sao Paulo. This reading placed these particular areas on the air quality map into the 'good' pollution rating bracket, which requires a reading of 50 or less for classification (with the closest to 0 being more optimal).

Other readings rose considerably, with figures of 55, 59 and 72 being present, along with a slew of active fires being shown on the map at the time when all of these figures were taken. Readings of 50 or below fall into the 'good' air quality rating bracket, and show up as green on the air quality map above, whilst readings within 51 to 100 are classed as 'moderate' and show up as yellow. Each subsequent pollution rating gets darker in color, reaching a peak with red, purple and maroon, which can indicate unhealthy to extremely hazardous levels of air pollution. Whilst there were some good levels of air cleanliness present throughout Sao Paulo, these may change at any given time, especially when there are fires taking place in the vicinity of the city. Changes in wind directions and strength as well as other polluting events can cause large amounts of pollutants to settle over various areas of the city, and as such the air quality map should be checked often to make sure that users are not within an area of extremely high air pollution readings. For times when such exposure cannot be avoided, certain preventative measures can also be taken to safeguard the health of individuals.

What does the air quality map tell you about the types of pollutants in the air in Sao Paulo?

The air quality map for Sao Paulo gives readings in the form of the US AQI figure, which is based on the aggregation of several main pollutants that are typically found throughout the world, hence the prevalence of their use in calculating the air pollution level.

These pollutants are nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, and PM10 and PM2.5, the two main forms of particle-based pollution. The latter of the two is far more dangerous, and although outright concentration levels are not shown on the air quality map for Sao Paulo when the US AQI reading is high and moves beyond the 'moderate' rating bracket, inhabitants of such areas will likely be in much higher contact with ultrafine particles and the aforementioned chemical compounds. As such, this can serve as information for users as to what pollutants they may be breathing when the air quality map readings are higher in Sao Paulo.

Are air quality maps helpful for people living in Sao Paulo?

Whilst all inhabitants of Sao Paulo can benefit from referring to the air pollution map, certain members of society may benefit more. Those whose health is at risk are more likely to benefit from keeping up with current pollution levels, and as such, those with pre-existing health conditions, compromised immune systems, the elderly, young children and babies, as well as pregnant women, call all benefit from using the air quality maps and the aggregated readings shown on them for the city of Sao Paulo.
