With fine particles in the bloodstream, all manner of illnesses can be caused, with cancer, heart disease and heart attacks, strokes, alterations to the nervous system, systemic inflammation and death all being possible. From here it can make its way into the bloodstream via the small air sacs, or alveoli in the lungs. At roughly 30 times smaller than the width of a human hair, it can bypass the body's defense systems and penetrate deep into the tissue of the lungs. It is this minute size, as well as the material that it is composed of that gives it its highly dangerous nature. PM2.5 refers to particulate matter that is 2.5 micrometers or less in diameter, on occasion going down to sizes many microns smaller. PM2.5 is used prevalently as a unit of measurement due to how dangerous it is, being considered as the most hazardous pollutant that can be found in the air in Cincinnati and throughout the state of Ohio. Why is Cincinnati polluted right now?Ĭontributing factors to elevated levels of pollution that can sometimes be seen in Cincinnati include ones that come from a variety of combustion sources, as well as other activities or industries that disturb large amounts of earth which can add heavily to the particle pollution levels. As such, careful monitoring of air quality forecasts can be utilized to stay up to date on changing pollution levels, available both on this page as well as the AirVisual app. In closing, Cincinnati is a city that maintains prolonged spells of good air quality but may be subject to sudden elevations that could cause adverse health effects among certain portions of the population. These include ones such as ozone (O 3), nitrogen dioxide (NO 2), sulfur dioxide (SO 2), carbon monoxide (CO), as well as the two main types of particle pollution, PM10 and PM2.5. The US AQI reading is a figure aggregated from the main pollutants found in the air, based on their volume. These were one step up in the 'moderate' rating bracket, which requires a reading of 51 to 100. In the same month, however, higher readings were also seen, with US AQI readings of 66, 77 and 88 all being on record. This is the most optimal level of air quality when referring to the US AQI rating, and requires a reading of anywhere between 0 to 50 to be classified as such. In July of 2021, Cincinnati presented with a US AQI reading of 31, placing it into the 'good' air quality rating bracket. This is a relatively poor ranking, indicating the pollution levels present were enough to skew Cincinnati’s reading to the point where it came in many positions ahead of other cities throughout the United States. As well as achieving this rating, it also placed the city in 2507 th place out of all cities ranked globally, for 2020. In 2020, Cincinnati presented with a yearly PM2.5 average of 10.1 μg/m³, placing it in the 'good' rating bracket of air quality. Whilst a majority of its months manage to fall within the more optimal levels of air pollution as set out by the World Health Organization, there have been other months on record whereby the pollution levels rise somewhat, making it possible for negative side effects or certain health issues to arise, particularly amongst vulnerable members of the population.
