Just enough 15 minutes on the edge of a busy road so that the traffic smoke start generating inflammation in the airwaysaccording to studies collected by BBC World. An experiment reported by the media demonstrates that direct exposure to automotive pollutants produces almost immediate effects on the healthevidencing the silent but accelerated impact of urban pollution on the body.
Analyzing samples collected after exposure, specialists found an increase in ultrafine particles capable of penetrating deep into the lungs and accessing the bloodstream. Among the risks identified by the researchers are increased chances of developing respiratory diseases, asthma and cardiovascular problemsaccording to data from BBC World.
The damage caused by air pollution Traffic not only affects the respiratory system. A report of the United States Environmental Protection Agency states that breathing these particles increases the risk of strokes and has been associated with the reduced cognitive function. Damage can be observed even in young people, indicate experts consulted by The NY Journal.
One of the experiments showed that, after being exposed to pollution in areas with heavy traffic, subjects experienced symptoms such as cough, throat irritation and even difficulty breathing.
Likewise, experts explain that the effects of ultrafine particles and gases derived from internal combustion engines can manifest themselves both in those who have risk factors and in previously healthy people.
Traffic in densely populated cities means that millions of people are continuously exposed to microparticles and toxic gases, with children and older adults being the most sensitive. The World Health Organization (WHO) estimates that environmental pollution causes about 4.2 million premature deaths annual.
The use of masks with adequate filters and reducing time in high traffic areas are recommended measures, particularly for vulnerable populations, according to experts interviewed by BBC World and The NY Journal.
Chronic exposure to traffic pollutants has been linked not only to persistent respiratory illnesses, but also to an increased risk of metabolic complications such as type 2 diabetes, according to recent research published in The Lancet. Studies in the urban population indicate that the incidence of these diseases is higher in areas near high-traffic avenues.
In cities like Madrid and Mexico Cityhealth authorities have implemented real-time air quality monitoring systems and vehicle restrictions for the days of greatest pollution. These programs seek to reduce pollution peaks and limit the exposure of the most vulnerable groups.
Furthermore, smart urbanization and investment in efficient public transportation emerge as key alternatives to reduce the concentration of particles. Organizations like the Pan American Health Organization highlight that the redesign of urban spaces, the incorporation of green areas and the promotion of active mobility could be decisive in mitigating the adverse effects of traffic on public health.
