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.

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).
