Tucson weather 14 day12/21/2023 ![]() When is the air at its most polluted in Tucson? These are some of the main causes of air pollution occurring within Tucson, with other ones such as occasional forest fires, construction sites and road repairs all being contributing factors to smoke, haze and fine particulate matter (PM2.5 and PM10). This can have a disastrous effect on the health of humans who respire it, as well as on the environment. Vehicles can release the same chemical compounds and hazardous particulate matter as factories can, as well as releasing large amounts of microscopic rubber particles into the air over time due to wear and tear on tire treads. With a huge population, coupled with a large amount of tourists moving in and out of the city (as well as the inhabitants commuting on a daily basis), there would subsequently be a large amount of pollution accumulating in certain areas due to the heavy overuse of cars. The other most prominent cause of pollution would be that of vehicular emissions. Of note is that certain factories and power plants will still use coal as a power source which can put out large amounts of chemical pollutants and particulate matter, all of which can raise the PM2.5 count. One cause would be regarding the fact that Tucson utilizes a large amount of fossil fuels for its energy supplies.Ī majority of this comes from natural gas, which although is a much cleaner alternative to other fossil fuels such as diesel or coal, still carries with it a fair amount of atmosphere polluting capabilities. What are some causes of polluted air in Tucson?Įven with such a respectable level of air quality present in Tucson, there are inevitably sources of pollution that would drive the PM2.5 count up somewhat, alluding to the fact that the air could be of even better quality. This very low reading placed it amongst one of the top cities in the world for clean air, coming in at 4373 rd place out of all cities ranked worldwide, as well as 1301 st place out of all cities ranked in America. In 2020, Tucson came in with a PM2.5 reading of 5.9 μg/m³ as its yearly average, a very good reading that placed it well within the World Health Organizations (WHO's) target goal at 10 μg/m³ or less, for the best quality of air. However, despite this it still manages to maintain very respectable level of air quality, even with such activities going on within the city. With a considerable population, coupled with the large movement of people in and out of the city, Tucson’s air is subsequently affected by this large scale anthropogenic activity. Tourism also accounts for a sizeable portion of the economy, and as such there would be a need to have a large number of hotels and guesthouses throughout the city to host the estimated 3.5 million annual visitors (in the pre-Covid era). Nowadays it sees much of its economic activity based around higher education and science facilities, tech companies as well as the military having a strong presence, acting as a large employer amongst the population within its various branches.
