Hugo O’Conor gave the go-ahead for the Spanish to build Presidio San Agustin del Tucsón in 1775. This was the beginning of Tucson as a military fort. After Mexico won its independence from Spain in 1821, it became part of the state of Sonora. In 1853, the United States bought 29,670 square miles (76,840 km2) of land from Mexico.
This land is now in southern Arizona and southwestern New Mexico. From 1867 to 1877, Tucson was the capital of the Arizona Territory. During Arizona’s time as a territory and early years as a state, Tucson had the most people, but by 1920, Phoenix had overtaken it. Still, population growth stayed strong in the last decades of the 20th century. In 2017, UNESCO named Tucson the first city in the United States to be a “City of Gastronomy.”
What are some things that make the air in Tucson dirty?
Even though the air quality in Tucson is pretty good, there are always going to be sources of pollution that make the PM2.5 count go up a little bit. This shows that the air could be even better. One reason could be that Tucson uses a lot of fossil fuels to power its homes and businesses.
Most of this comes from natural gas, which is a cleaner fossil fuel than diesel or coal but still pollutes the air. Some factories and power plants will still use coal as a power source, which can release a lot of chemical pollutants and particulate matter, all of which can raise the PM2.5 count.
Emissions from cars and trucks are the other major source of pollution. With a large number of people living in the city and a lot of tourists coming and going, as well as people who live there commuting every day, there would be a lot of pollution in some areas from the overuse of cars. Vehicles can release the same chemical compounds and dangerous particulate matter as factories.
Over time, the wear and tear on tyre treads can also release a lot of tiny rubber particles into the air. This is bad for the health of people who breathe it in and for the environment as a whole. These are some of the main things that cause air pollution in Tucson. Other things, like occasional forest fires, construction sites, and road repairs, also contribute to smoke, haze, and small particles (PM2.5 and PM10).
When does the air in Tucson get the most dirty?
When you look at the data collected over the course of 2020, you can see that there was a time when the air pollution levels were much higher than the rest of the year. However, the air quality in the city is so good that the levels were still within acceptable ranges. Around August, these more polluted months started, and they lasted until the end of the year.
During some of the last months of the year, this can be caused by a much higher demand on power plants to heat homes and businesses. This is a common sight in many cities around the world that experience a big drop in temperature at certain times of the year. It’s important to note that pollution can also rise during hotter months for different reasons.
In July, the reading was 34.8 g/m3, which was a very good number. In August, the number went up to 7.5 g/m3. From this month on, the air pollution got even worse. From September to December, the readings were 8.1 g/m3, 7.4 g/m3, 7.7 g/m3, and 8 g/m3, which were some of the highest readings of the year.
December is one of the colder months in Tucson, which is how the pollution reading made sense. With an 8 g/m3 reading, December was the most polluted month of the year (before it dropped down significantly in the early months of the following year, in accordance with the PM2.5 readings shown in early 2020). This shows that the most pollution in Tucson would be in the months of August through December.
What kinds of pollution can you find in Tucson?
Pollutants like nitrogen dioxide (NO2) and sulphur dioxide (SO2), which are mostly released by cars, are the most common in Tucson. Other pollutants like carbon monoxide (CO), black carbon, and volatile organic compounds (VOCs) are also common. Ozone is another pollutant that is especially bad in the United States. It is made when oxides of nitrogen (NOx) and other chemical pollutants or gases are exposed to a lot of sunlight, turning them into ozone (O3).
This could explain why PM2.5 levels go up a little bit in the summer, when a lot of ozone is made when a lot of vehicles are used and a lot of sunlight hits the exhaust fumes from those vehicles. Chemicals like benzene, toluene, xylene, methylene chloride, and formaldehyde are all examples of volatile organic compounds.
Waste Management Issues In Tucson
The city of Tucson has had a waste management issue for a long time. Unfortunately, they have been unable to come up with a suitable solution. This makes it very difficult to manage their waste. With the population of the city increasing every year, it is getting worse by the day. The city has tried various methods to manage their waste but they have failed.
They have been looking for new ways to manage their waste and have recently started to look at recycling. While recycling is a good way for them to manage their waste, it is not an ideal solution. The truth behind the Tuscon’s waste management problems is the city’s mismanagement of the landfills. As the population of Tuscon exponentially increases, the city’s landfills have reached their maximum capacity and have had to lower their prices to attract new truckers and businesses in order to dispose of their trash.
Tucson’s waste is often dumped in Oklahoma.These actions have increased the chances of illegal immigration and drug trafficking into the United States. One proposed solution to this problem is to build a new landfill on the other side of Tuscon, and to improve the recycling rate in order to reduce the amount of waste being produced. Another possible solution is to decrease the amount of organic waste in the landfills, which will lower the risk of methane gas explosions and help reduce the amount of gas that is released into the environment.
