Pátzcuaro is a large town and municipality located in the state of Michoacán, Mexico. According to a census conducted in 2005, the population was estimated to be approximately 80,000 people.
At the beginning of 2022, Pátzcuaro was experiencing a period of “Moderate” air quality with a US AQI reading of 91. This United States Air Quality Index number is an internationally used set of metrics supported by the World Health Organisation (WHO) and is used to compare the air quality in different cities throughout the world using comparable standards. It is calculated by using the levels of the six most commonly found pollutants such as nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide and both sizes of particulate matter, which are PM2.5 and PM10. If all six figures are not always available in which case, a level is calculated by using what data there is. In Pátzcuaro only the pollutant PM2.5 was measured which was recorded as being 31.2 µg/m³.
This level of PM2.5 is just over three times the recommended safe level of 10 µg/m³ as suggested by the World Health Organisation (WHO) as being an acceptable level. Although no amount of air pollution is considered to be safe.
When air pollution is classified as being “Moderate” the given advice would be to remain indoors as much as possible, closing doors and windows to prevent the ingress of more polluted air. Those who are more sensitive to poor quality air should avoid venturing outside until it improves. If this is unavoidable, then a good quality face mask should be worn at all times. All types of outdoor exercise should be avoided until the air quality improves. There is a downloadable app from AirVisual.com which is suitable for all operating systems and gives the latest information regarding air quality in real-time.
Air quality can be affected by many things, therefore it can and does change rapidly depending on the local conditions. Looking back at the 2020 figures published by IQAir.com, it can be seen that the month of June produced “Good” air quality with a reading of 11.5 µg/m³. The remaining eleven months saw air quality from the “Moderate” category with figures between 12.1 and 35.4 µg/m³. These figures are all expressed in microns per cubic metre.
Records for air quality were first kept in 2019 when the annual average was noted to be 20.8 µg/m³. The following year of 2020 saw an improvement when that figure was 18.0 µg/m³, but this lower figure was almost expected because it would have been affected by the COVID-19 pandemic as many vehicles were no longer in daily use because the offices were closed and the staff encouraged to work from home, in an attempt to halt the spread of the virus. Many factories and non-essential production units were also required to close which removed their emissions from the atmosphere, albeit on a temporary basis. Worldwide, cities reported a much better quality of air due to the general lack of traffic pollution in city centres due to the pandemic.
In Michoacán, the main cause of environmental contamination is in the so-called mobile sources. Transportation, and motor vehicle traffic in general, generates carbon monoxide that is fixed in the atmosphere and that we breathe, which affects our quality of life.
Every day around 2 million vehicles circulate through the streets of the state, mainly in the metropolitan area, where the largest number of vehicles is concentrated, with more than 700 thousand units; this means that it is there where the greatest air pollution in the entity is found.
In Michoacán, four out of five people own a motor vehicle; that is, it is a very high standard. For this reason, we need to prioritize the use of urban transport and, precisely, one of our strategies is the renewal of the vehicle fleet, so that citizens have an adequate service and can opt for it.
For example, it is necessary to abandon agricultural burning, forest fires caused to change land use, and use the vehicle in moderation; let's share our private vehicles with family members and, of course, keep them in good condition and properly serviced. Let's not forget to walk or cycle which is also a good option.
In the document of the Management Program to Improve Air Quality in the State of Michoacán 2015-2024, it is read that 17 measures have been established to reduce the emission of pollutants, of which six are institutional strengthening, health and environmental education and communication; and eleven are aimed at emitting sources such as industry, motor vehicles, businesses and services.
Even if you can't see it, the air you breathe can affect your health. Polluted air can cause shortness of breath, allergy flare-ups, or asthma, and other lung problems. Long-term exposure to air pollution can increase the risk of other diseases, including heart disease and cancer.
Many residents experience some form of air pollution-related symptoms, such as watery eyes, coughing, or wheezing. Even for healthy people, polluted air can cause irritation or breathing difficulties during exercise or outdoor activities. Your actual risk depends on your current health status, the type and concentration of the contaminant, and the length of time you are exposed to contaminated air.
