Nuevo León state issued its tenth environmental alert for 2023 so far on November 17.This alarm phase is due to high concentrations Particulate matter less than 10 microns (PM10) In metropolitan areas.
What are the consequences of pollution?
The pollution elements present in urban environments represent A silent threat to human health.
also respiratory problems Examples include asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD) Cardiovascular diseases, Another important impact is Pollution directly affects the brain.
In large cities with high levels of air pollution, the simple act of breathing increases the risk of experiencing oxidative stress and premature deterioration of the central nervous system.
Epidemiological studies also suggest that in the future, in addition to an aging population, air pollution may cause more people to develop cognitive problems earlier. According to the recent Global Burden of Disease study, The study published in The Lancet analyzed the prevalence of dementia in 204 countries and predicted that the number of people with dementia worldwide will increase significantly, from 57 million in 2019 to 153 million in 2050.
What are the most dangerous pollutants we breathe?
PM2.5 and PM10 particulate matter Particles of dust, soot, ash, cement, waste or pollutants between 2.5 and 10 microns in diameter From road traffic, from engine combustion, braking and tire wear, can penetrate the lungs and may reach the central nervous system. Its exposure is associated with cognitive problems and increased risk of neurodegenerative diseases.
also from Carbon monoxide (CO) Its long-term exposure may produce long term neurological effects. It has been linked to cognitive problems, memory impairment, and an increased risk of neurodegenerative diseases such as Alzheimer’s disease.
Other pollutants that affect the nervous system are, Ozone (O3), nitrogen dioxide (NO2) and sulfur dioxide (SO2).
